In December 2025, governments gathered in Belém, Brazil, for the 30th Conference of the Parties (COP30) against a backdrop of record heat, torrential rains, and growing calls to move away from fossil fuels. The final outcome fell short of expectations for many. Fossil fuels were not mentioned in the agreed text, and the existing Nationally Determined Contributions (NDCs) still point to a dangerous 2.6°C warming trajectory, far above the level of 1.5°C called for in the Paris Climate Agreement and by science. 

Peter du Pont of SIPET Connect spoke with Frauke Röser, Co-Founder and Director at NewClimate Institute, about what COP30 revealed about the state of global climate politics, the emerging agenda of “transitioning away from fossil fuels”, and what all of this means for countries working on the energy transition, including in Southeast Asia. 

*** 

SIPET Connect: To start, could you tell us about NewClimate Institute and the work you focus on? 

Frauke: NewClimate Institute is a not-for-profit think tank that follows the international climate policy agenda. Our main focus has been on just transitions, the mitigation agenda, and the finance agenda, and we are also increasingly engaging on the issues of adaptation, resilience, and loss and damage. But the core of what we do is really around just transitions, mitigation, and the finance that goes with them. 

We are based in Germany with two offices, one in Berlin and one in Cologne. We are now roughly 50 people, with a very diverse team of more than 20 nationalities. We work on climate policy and transitions, and we track climate action, climate finance, and carbon markets. Article 6 and international carbon trading are also important strands of our work, and we follow those discussions quite closely at the COP. 

One of the things we are known for is the Climate Action Tracker, which looks at what countries are putting forward in the form of their NDCs and climate targets and relate that back to the Paris Agreement goals. This is one of the key inputs we provide at COPs. Beyond that, COPs are also a space for us to follow negotiations, exchange with peers, meet partners, and stay in touch with the international community. 

SIPET Connect: How did COP30 in Belém feel on the ground, especially for civil society and indigenous representatives? 

Frauke: In some ways, it was a relief. I was happy that, for the first time in several years, the COP was held in a democratic country again. Compared with Azerbaijan, Dubai, and Egypt, the visibility of civil society and particularly indigenous representatives was very high. That was really good to see. 

At the same time, you could really feel climate change in a very immediate way. It was extremely hot. I stayed a bit longer in Brazil, and the temperature difference coming back to Germany was a real shock for my body. During the COP, there were torrential rains that were so loud you sometimes could not have a conversation because of the sound of rain on the rooftops, and then there was the big fire. So it had all the drama of the climate crisis around it. In that sense, it brought the issue home very clearly. 

Unfortunately, though, the political outcome did not fully reflect the urgency that you could feel there. 

SIPET Connect: Going into COP30, what were you hoping to accomplish, and which issues were you following most closely? 

Frauke: I would not say we had targets in the sense of expecting the COP to suddenly deliver what is needed, given the climate crisis we are facing. In the current geopolitical setting, it was clear that the international community was not going to magically come together in Belém and decide on ambitious climate action. Especially with the United States pulling back in various ways, it was a difficult set-up. 

Personally, I was following three things most closely: the discussions on transitioning away from fossil fuels, the just transition agenda, and the related debates on levels of climate finance. Finance is always at the core of the negotiations and often the stumbling block that prevents things from moving fast and ambitiously. 

Other colleagues of mine focused more on Article 6 and international carbon markets, which we view quite critically, and on the overall picture of NDCs and where we stand relative to the Paris Agreement. 

SIPET Connect: Many governments updated their NDCs ahead of COP30. What did we learn from these new NDCs, and what does that mean for the energy transition? 

Frauke: You are right that some updated NDCs are more ambitious, and that is positive. But others are not. Some major economies, such as India, had not even submitted their NDCs. And the EU submitted its NDC very late, essentially a day before the COP. 

China’s NDC is somewhat more ambitious but still short of what we know the country can do, and compared to what we see happening in the real economy. That is an important point: NDCs are a useful political tool and framing, but they often do not portray reality very well. In some cases, like the EU, the real economy is moving much faster and in a much more ambitious way than what is written in the targets, and countries then overachieve their NDCs. 

Overall, in our analysis, the current NDCs will lead to a temperature increase 2.6°C by the end of the century, largely the same as last year, meaning that the new 2035 NDCs did not change the picture. That is pretty disastrous when you look at the scientific models. I cannot quote all the exact submission statistics off the top of my head, but I can say that many NDCs came late, some were not very ambitious, and some big emitters had not submitted at all. 

SIPET Connect: One of the initiatives that drew attention at COP30 was the “Transitioning Away from Fossil Fuels” (TAFF) agenda. How do you see that process? 

Frauke: The TAFF initiative was indeed one of the more interesting developments. It was started by Colombia and at some point there were more than 80 countries behind it, including many European countries. 

There was quite a bit of hope that this initiative would find its way into a final COP decision—some kind of formal language or text. In the end, it did not. Fossil fuels were not even mentioned in the final outcome, which was disappointing. 

For me, the main take-away is that there is now a large and significant group of countries that clearly want to pursue an agenda of transitioning away from fossil fuels. They have organized themselves around this and are continuing. There will be a conference in Colombia early next year, co-hosted with the Netherlands, to follow up on TAFF. 

Many of the countries behind TAFF are fossil fuel importers. From an energy security and independence perspective, you would expect them to have a strong interest in accelerating this transition. On the other side, you have fossil fuel exporting countries who are trying to stall it. I do not think they can stop it. At best, they can delay it. That is really what they are aiming for. 

So even though TAFF did not make it into the final text of COP30 declaration, it has created a movement and a platform that I hope will grow into the kind of multilateral collaboration we need. 

SIPET Connect: Given the current geopolitical context, how do you see the role of COPs now? Can they still deliver meaningful outcomes? 

Frauke: If you think back, the Paris Agreement is almost a miracle. I do not think we would be able to negotiate such an agreement today. The idea that 194 countries would agree unanimously on something that ambitious seems almost inconceivable now. 

So we have to be realistic. Having a unanimous, highly ambitious agreement from 194 countries is extremely difficult. Even COP decisions are, to some extent, voluntary. That is why it is important to have issue-focused coalitions and initiatives like TAF. They allow a “coalition of the willing” to move ahead together. 

At the same time, COPs remain extremely important. They show that multilateralism is not dead. They provide a forum where all countries have to come together and, in a very transparent way, show the world where they stand. That visibility is crucial. 

You can also see that something is at stake simply by looking at who shows up. There are now many lobbyists attending COP. If nothing in these processes threatened existing business models, they would not bother to be there. So what happens at COP, including NDC updates and long-term strategies, does matter, because it shapes the direction of travel and the policy signals that follow. 

SIPET Connect: You mentioned climate finance and the need for just transitions. What did COP30 change on those fronts, and what still needs to happen? 

Frauke: On finance, there was some progress, particularly around adaptation finance, which I see as a positive step. But in terms of the overall provision of climate finance, there is still a long way to go. 

We need to move forward with reforming the international financial architecture, phasing out fossil fuel subsidies, and making sure we are not only mobilizing more investment for green sectors but also redirecting investment away from brown sectors and into green ones. It is not enough to simply add green finance on top of continued fossil investment. 

On just transitions, there was more explicit recognition of what transitions mean for people, workers, communities, indigenous peoples. That social dimension was brought into the debate more formally, which I think is a success. But again, these are only starting points. The key is whether countries now turn that recognition into policies, finance, and support mechanisms that actually help people through the transition. 

SIPET Connect: The funding environments over the past year has been extremely challenging for many climate organizations. How has this affected NewClimate Institute and your peers? 

Frauke: It has been difficult. We did not have USAID funding ourselves, but we are impacted by the ripple effects. When U.S.-based organizations are hit by funding crises, they turn more to European funders. At the same time, many foundations with links to U.S. corporates have partly pulled back from climate work. And then you also have governments like Germany reducing some budgets. 

So the squeeze is coming from all sides: more competition for European and foundation funding, and fewer resources overall. Organizations like ours have had to adapt—rethinking funding models, being more strategic, and trying to protect the quality of our work while dealing with more uncertainty. 

SIPET Connect: Many of our readers are working on the energy transition in Southeast Asia. What should governments and private sector actors in this region take away from COP30? 

Frauke: I would highlight a few things. 

First, transitioning away from fossil fuels is a question of when, not whether. That message came through quite clearly, even if it is not yet reflected in the formal COP text. Countries that prepare early will be better off economically and socially. 

Second, the just transition is now more firmly part of the conversation. Governments need to think about what the transition means for people and communities, including indigenous communities, and to design policies that reflect that. 

Third, for public sector actors, it is important to have a longer-term vision of where the economy is going and what is actually beneficial for the country and its communities. When you look at the hard numbers, you usually find that moving faster on the transition is economically and socially more advantageous than delaying it. 

For private investors, everything depends on signals and the framework they operate in. They follow investment opportunities. When governments send clear, reliable signals about the direction of travel and put the right incentives in place, the private sector responds. COP30 did not fully provide that clarity, but initiatives like TAFF and the stronger emphasis on social and justice issues still send important impulses. 

SIPET Connect: How important are NDCs themselves as signals for investors, and where do they fall short? 

Frauke: I am not sure investors read NDCs in detail. NDCs are high-level political signals about where a country says it wants to go. They need to be underpinned by concrete policies, sectoral roadmaps, and regulatory changes that investors actually respond to. 

That said, NDCs and long-term strategies do matter. The level of lobbying around them shows that. If they were irrelevant, you would not see so many actors trying to influence them. They frame what comes next in terms of laws, regulations, and incentives. 

Ultimately, though, each country has to take these high-level targets and translate them into very specific plans and policies across sectors. That is what gives investors the clarity they need. 

SIPET Connect: In spite of the 2.6°C trajectory, you still sound cautiously hopeful. Where do you see signs of progress? 

Frauke: I would say I am worried and hopeful at the same time. Clearly, 2.6°C is not acceptable. But a few things give me hope. 

One is that multilateralism is still functioning on some level. Countries are still coming together at the COPs, and that matters a lot. It forces them to be transparent about where they stand, and it keeps the pressure on those who are blocking progress. 

Another is what we see in the real economy. In many parts of the world, the deployment of renewable energy and the falling costs of technologies show that the transition is happening and that it is unstoppable. 

And if you compare where we are now with ten years ago, we have moved the needle. In 2015 the current policies scenario led to 3.6°C of warming by 2100.. Now we are at 2.6°C. That is still far from where we want to be, but it shows that action makes a difference. 

Looking ahead, I think one of the important next steps is for more countries—maybe not all 194, but a critical mass—to adopt credible roadmaps for phasing down and phasing out fossil fuels. Even if it is “only” 80 countries out of 194, such roadmaps can send powerful signals to investors and real-economy actors. 

So yes, progress is too slow, and it is not yet enough. But things are moving in the right direction. Our task now is to speed up that movement and make sure that the transition is fair. 

Viet Nam, the Philippines and Indonesia have the resources and workforce to lead ASEAN’s clean energy future, but turning potential into progress hinges on creating stable, predictable policies and taking bold and near-term actions to secure investment and stay competitive.

In October 2025, Bangkok hosted its first-ever Bangkok Climate Action Week (BKKCAW), a nine-day citywide initiative featuring more than 270 events across 60 venues. Conceived as a civic movement rather than a conventional conference, the week aimed to take climate action beyond expert and institutional circles, drawing in citizens, artists, youth, entrepreneurs, and policymakers alike.

Peter du Pont of SIPET Connect spoke with Leo Horn-Phathanothai, Founder and Executive Director of JUTI (Just Energy Transition Incubator) and a recently appointed Board Member of Greenpeace Southeast Asia (GPSEA).  JUTI organized BKKCAW in collaboration with a diverse and inclusive set of partner organizations. In the interview, Leo reflects on the ideas behind the event, the response it generated, and what it reveals about how Southeast Asia can build civic power and culture around the energy transition.

***

SIPET Connect: To start, could you share a bit about your background and how you came to work in energy, climate, and development, and how JUTI fits into that journey?

Leo: I’ve spent just over two decades at the intersection of environment and development, first as an environmental economist, then as a diplomat, a think-tank director, and in other technocratic organizations. What’s guided me from the start are two enduring passions: a love of nature, and an outrage at the persistence of poverty in a world of abundance. Those two things—love and outrage—shaped my sense of social justice and put me on this path.

In the first half of my career, I was often the lone environmentalist inside development institutions, trying to bring climate change and environmental issues into the center of the development agenda. In the second half, I worked from the other side, within environmental organizations, trying to bring people to the center of climate and environmental work. In short, always bridging climate and development concerns.

I founded JUTI early this year with the aim of localising ambitious action on climate and nature. We do three things: support high-potential local actors to grow their impact; orchestrate collaboration across a fragmented ecosystem; and work on the deep leverage points for systemic change, that is, narrative and culture, to help shift expectations of what’s possible. Bangkok Climate Action Week brings all three of those strands together in one space.

SIPET Connect: The inaugural Bangkok Climate Action Week was a huge success. What was the core vision behind it?

Leo: The vision is to build a movement. We wanted to take climate out of its narrow “climate box” and place it in a whole-of-society context. The goal was to activate people, to bring them into the climate action arena and give them greater ownership of a transition that is already underway. The question is no longer how to start the transition, but how to make sure it leads somewhere good and how to ensure it delivers benefits for everyone instead of being captured by incumbents.

That requires building civic power. We need strengthened public participation and engagement to shape the transition, build political demand for better, and redefine what kind of future we want to create together.

SIPET Connect: As an active participant in Bangkok Climate Action Week, one of the striking features I observed was how inclusive it felt. How did you design something that reached beyond the usual policy and industry audiences?

Leo: It started with how we built it. This wasn’t a top-down exercise led by one person; it was collective from the start. We created a diverse steering committee that included educators, architects, artists, policy experts, former ministers, agency heads, and youth activists. I’d tell them: if Bangkok Climate Action Week could reflect the diversity of this group, it would succeed. The heavy lifting was done by a multi-talented core team constituted by a similarly diverse group of individuals from diverse organizations, including III Muses, PXP Sustainability, Creative Migration, and Saunter Media.

We also designed it for those who are usually excluded, including children, older people, and those outside formal climate or policy spaces. It’s the same principle as city planning: if you design a city for the most vulnerable, you create one that works better for everyone. Radical inclusion was our design principle, and it led to richer conversations and new forms of collaboration.

SIPET Connect: What did you take away from the results?

Leo: Honestly, it exceeded my expectations. We focused on accessibility, bringing climate issues to people instead of expecting them to come to us. The outcome spoke for itself: around 270 events, and over 77 000 visitors. Every room I walked into was full. That level of turnout told us something powerful: there’s readiness, and a real hunger for this kind of civic space.

SIPET Connect: Why do you think the response was so strong?

Leo: Because people already care. Surveys everywhere show that concern about climate change is extremely high, often 90 per cent or more, but actual engagement remains low. That’s not apathy; it’s a lack of opportunity. When you open the space, people walk in. Thailand is no exception.

SIPET Connect: What were some of the most memorable outcomes or new collaborations that emerged?

Leo: The most important outcome was the participation itself, the diversity and energy of people who stepped forward for the first time. That, to me, signals the start of something bigger: a civic awakening, even a regional one, where Asian voices and experiences take center stage.

There were also concrete results. One was the Climate Lighthouse, a partnership between Shanghai Climate Week and Bangkok Climate Action Week—two Asian cities that are both vulnerable to climate impacts and leading in innovation. Another was the Invest for Nature coalition, which brought together around 20 civil society organizations in Thailand working on nature finance. The aim is to equip capital with a better lens for identifying high-integrity investments in nature, distinguishing what’s real from what’s greenwashing.

We also ran a youth innovation challenge, where teenagers aged 13 to 18 presented collaborative ideas for climate solutions. It flipped the typical “Shark Tank” model—judges weren’t extracting value but nurturing it. The quality of ideas was incredible, and we’re even exploring turning it into a counter-cultural television program next year that celebrates cooperation over competition.

Another important seed was the Bangkok Climate Action Declaration, which emerged spontaneously as a civic call to political leaders. It’s a first step toward building sustained public demand for stronger action.

SIPET Connect: The Clean Air Act was passed unanimously in Parliament soon after the event. Do you see a connection?

Leo: I think it reflects a shared moment. We’re moving from an era of complacency to one of agency. People are fed up with pollution and inequality; they expect better. Bangkok Climate Action Week tapped into that energy. People didn’t come because of personalities; they came because the space was opened up for them, and they were ready to use it.

SIPET Connect: Looking ahead, how will you build on this momentum next year?

Leo: We approached this first edition as an experiment, to test whether creating a new kind of civic space would draw people in. It did. Now we can be more ambitious.

Next year, we’ll double down on culture as the common language of action. Culture connects who we are with the future we want, and it’s our most abundant and endlessly renewable resource. We want to cultivate a culture of care, courage, and collaboration.

We’ll also activate the community of action that has formed. Success won’t mean having more events; it will mean stronger ones. I’d rather see fewer, co-designed sessions that bring together communities and deepen collaboration.

And we’ll keep the experimental spirit alive. Bangkok Climate Action Week will remain a laboratory, an open space to test ideas. Some concepts already emerging include using football as a platform for unity and creating new spaces for dialogue between citizens, businesses, and policymakers. The focus is collaboration, not confrontation.

SIPET Connect: The event drew significant participation from across Southeast Asia. How do you see its regional role evolving?

Leo: We always saw Bangkok Climate Action Week as a regional platform. For the first edition, we needed to ground it locally and ensure it felt authentic in Thailand. Even so, it turned out to be vibrantly regional. My guesstimate is that roughly a third of the events, about 80 to 100, had an explicit regional dimension.

Next year, we want to bring regional partners directly into the steering committee and co-create from the start. The experience has shown that we can be more confident in our regional ambition. People across Southeast Asia felt that this was an Asian moment, not just a Bangkok one.

SIPET Connect: Many of our readers are development partners working on the energy transition. What lessons can they take from this experience?

Leo: The first lesson is trust, trust people, and resist the urge to over-format. We didn’t prescribe themes or sectors; we simply created the space. More than 95 per cent of proposals aligned with the spirit of what we were trying to do. That says a lot about latent understanding and readiness.

The second is humility. Experts, myself included, often think we have the solutions, but that mindset can disempower others. Our role should be to equip people with tools, knowledge, and evidence, and then trust them to find their own paths.

Third, create space for experimentation. Development work is often too risk-averse. Transformation requires a portfolio that balances predictable, low-risk projects with space for new, uncertain ideas. That’s where innovation comes from. China’s development success was rooted in local experimentation that was scaled up; there’s a lesson there for all of us.

Finally, changing the narrative matters. One of our priorities for next year is to run coordinated communications campaigns with partners, pooling resources and aligning messages to shift public understanding of the energy transition. Culture and communication are what make participation, finance, and political will possible.

For decades, regional power trade in Southeast Asia remained more aspiration than action. Today, the ASEAN Power Grid is beginning to move from plans on paper to projects on the ground. In this Transition Toolbox conversation, Peter du Pont of SIPET Connect speaks with Keiju Mitsuhashi, Director for Southeast Asia & Pacific Energy Sector at the Asian Development Bank (ADB), about the momentum behind the ASEAN Power Grid and ADB’s work with the Philippines on renewables, grid modernization, and enabling infrastructure. Keiju shares his experience and reflections on how regional interconnections, domestic grid development, and national reforms are advancing together—linking ASEAN’s ambitions for increased power trade with the Philippines’ drive for more clean energy from geothermal, and offshore wind resources, as well as smarter, greener, and more resilient power grids. 

**** 

SIPET Connect: To start, could you introduce your role and focus at ADB?

Keiju Mitsuhashi: I am the Director for Energy Sector for Southeast Asia and the Pacific at ADB. I took on this role about two years ago after my assignment in Viet Nam. Our work is about delivering prosperity, inclusiveness, resilience, and sustainability across Asia and the Pacific through financing concrete energy projects, advancing complex reforms, and promoting innovative solutions.

SIPET Connect:  Regional power trade has long been on the agenda, but it has only recently begun to move from talk to action. The ASEAN Power Grid (APG) has been central to these discussions. What’s driving the new momentum toward making it a reality?

Keiju Mitsuhashi: The idea of an APG has always made sense but turning it into reality is complex. Grid-to-grid interconnection requires aligned regulations, grid codes, standards, and legal frameworks, and adding power trading creates another layer of difficulty. That is why progress has taken time, but it is now happening. The ASEAN Interconnection Masterplan Study (AIMS) III plan identified 18 interconnections in the region; nine are already connected, although many of these will need to be upgraded. We financed the West Kalimantan–Sarawak link in 2016 and saw a quick payback. The Lao–Thailand–Malaysia–Singapore pilot traded 100 megawatts across four countries and is now expanding to 200 megawatts. We also financed the Monsoon Wind Power in Laos—600 megawatts for export to Viet Nam—which is source-to-grid rather than grid-to-grid, but still part of the APG story.

What’s different now is the combination of technology, demand, and policy. Renewables are far cheaper than when earlier power plans were drawn up. Power demand in Southeast Asia could triple by 2050, driven by the growth of population, air-conditioning, data centers, and EVs, among others. And there is stronger political direction: leaders have agreed that the region’s grids should be connected by 2045. Singapore’s announcement that it will important six gigawatts of clean energy created a credible off-taker and shifted the market conversation. Some countries have access to abundant, low-cost renewables, and others do not; in many cases, imports are the least-cost way to bring in green electrons.

SIPET Connect: How do governments balance energy security with reliance on imports?

Keiju Mitsuhashi: Energy security comes first. In the 1990s and 2000s, industrial growth was primarily driven by coal-fired power plants in Southeast Asia, and many of those plants are still relatively young. That can’t continue if countries are serious about achieving net-zero emissions and about staying competitive for exports and attracting foreign investments in the region. Clean energy is a core part of an energy security strategy now. That’s why we’re moving from planning to implementation. You’ll see that reflected in ministerial meetings this year.

SIPET Connect: Where does ADB fit into the ASEAN Power Grid, as it moves forward?

Keiju Mitsuhashi: While we coordinate at the ASEAN level, we also engage with sub-regional work within the Greater Mekong Subregion (GMS), the Brunei Darussalam–Indonesia–Malaysia–Philippines East ASEAN Growth Area (BIMP-EAGA), and the Indonesia–Malaysia–Thailand Growth Triangle (IMT-GT), because trades usually start bilaterally, gradually, and expand from there. We have a cooperation arrangement with Singapore’s Energy Market Authority on clean-energy imports. At the ASEAN level, we and the World Bank are launching the APG Financing Initiative with the ASEAN Centre for Energy and the ASEAN Secretariat. The goal is to mobilize funds, including from the private sector, alongside sovereign lending because a large share of the APG will need to be privately financed.

SIPET Connect: What has to change to bring more private investment into power generation and interconnections?

Keiju Mitsuhashi: For generation, you need bankable power purchase agreements (PPAs), whether through auctions or feed-in-tariff schemes before power markets develop. Transmission is tougher. It’s regulated and mostly state-owned in Southeast Asia, and third-party access is still limited. Merchant models common in Europe may not be practical here. Realistically, however, you’re looking at public–private partnerships (PPPs) and availability-based structures for subsea cable projects. Further, interconnections must ensure grid stability. Domestic grid strengthening is critical. Grid links can increase vulnerability if they’re not planned carefully, so sequencing matters.

SIPET Connect: How will the APG Financing Initiative actually work, and how do you plan to de-risk?

Keiju Mitsuhashi: We’re coordinating project preparation and financing and setting up a financiers’ forum that brings in development financiers, commercial banks, developers, and philanthropies. De-risking happens in three places. At the policy level, we use policy-based lending to support reforms. In preparation, we can fund the up-front work—such as undersea surveys, environmental and social assessments, and legal and regulatory reviews—often with public or blended finance that can be refinanced later. And during construction, tools that ADB and multilateral development banks have can help manage cross-border and political risks so investors and other lenders can come in with confidence.

SIPET Connect: Let’s turn to the Philippines, where ADB has been very active over the past few years. What does partnership look like today?

Keiju Mitsuhashi: We have revamped our partnership with the Philippines in the energy sector. In 2001 we supported the Electric Power Industry Reform Act, which shifted the sector to a privatized structure. Today the country targets 35 percent renewables by 2030 and 50 percent by 2040. Policy signals are important, but not sufficient; public-sector interventions are needed alongside private investment. We’re supporting climate policy reforms with the Department of Energy (DOE), and other departments. We’re preparing a derisking facility for geothermal exploration and drilling, with financing targeted for 2026, because exploration risk has stalled development for two decades. We’re expanding energy access with results-based approaches for communities that still lack reliable electricity. We’re helping public-building energy efficiency retrofits to build market capacity and demonstrate models. On offshore wind, we’ve supported  Department of Environment and Natural Resources (DENR) to issue the department regulation on environment compliance certificate. We’re also working on common-use offshore wind ports, so developers have the infrastructure they need. On transmission, we’re exploring how public action can accelerate smart and green grid upgrades so renewables can be integrated at scale.

SIPET Connect: Offshore wind in the Philippines is getting a lot of attention these days. How do you see it unfolding?

Keiju Mitsuhashi: The Philippines has some of the strongest offshore wind resources in Southeast Asia, with estimates ranging from 50 to more than 150 gigawatts of potential. DOE have already issued notice to auction to subscribe 3.3 gigawatt of offshore wind power by 2028–2030, marking an important step forward. For developers, certainty around ports and support infrastructure is critical. Those facilities are likely to be publicly financed as common goods, which reduces demand risk, lowers overall project costs, and helps make bids more competitive for both consumers and industry.

SIPET Connect: Stepping back, what are your big lessons for the region’s transition?

Keiju Mitsuhashi: First, the energy trilemma—security, access, and affordability—has to anchor decisions. Energy transition itself cannot be the only or ultimate goal. Second, there’s no transition without transmission; clean power generation only works if the grid can carry it. And while renewable generation costs are down, integration is not free. Once variable renewables rise above roughly a third of the mix, the grid systems need storage, smarter operations, and more capacity to avoid curtailment. Third, the transition may not always look cheap, but the alternative—sticking with fossil fuels—raises costs and undermines competitiveness. The question isn’t whether we pay; it’s whether we build systems that are cleaner, more secure, and ultimately better for economies in the long run.

In Southeast Asia, unlocking private capital for urban decarbonization requires practical finance and delivery mechanisms that work within existing institutions. In this Transition Toolbox conversation, Peter du Pont of SIPET Connect speaks with Marc S. Forni, Lead Urban Specialist at the World Bank, about the World Bank’s Regional Low Carbon Cities (LCC) Program. 

The LCC Program advances a replicable approach—using performance-based contracts, “stapled” lending through state-owned and commercial banks, and clear rules for crediting—to help cities and large asset owners implement high-return investments at scale. 

What makes this approach compelling isn’t just its technical design—it’s the way it threads finance, regulation, and real-world incentives into something cities can actually use. As regional actors look for scalable solutions to climate action at the urban level, this is a toolkit in the toolbox worthy of careful examination! 

*** 

SIPET Connect: To begin, what is the World Bank’s Regional Low Carbon Cities Program, and why does it matter for the energy transition? 

Forni: The LCC Program is a practical playbook for getting proven technologies—like efficient lighting, rooftop solar, modern HVAC, and fleet electrification—into public and quasi-public facilities at scale. In settings where municipal borrowing is limited, we position cities and real estate operators as “brokers” of performance-based contracts with energy service companies (ESCOs), while partner banks provide the lending. That lets projects move without new public debt, and it creates a path that can be replicated across multiple cities and asset classes. 

SIPET Connect: You often say cities can broker rather than borrow. What changes when you take that view? 

Forni: It widens the solution set. Instead of asking whether a city can take on debt, we focus on structuring shared-savings contracts that are bankable on their own merits. The city sets performance requirements; an ESCO delivers and is paid from verified savings; and a state-owned or commercial bank provides a loan backed by the project cash flows. Instruments like receivables assignment or fiscal intercepts help de-risk repayment. Because many of these upgrades generate double-digit returns, the model is attractive to both public asset owners and lenders. 

SIPET Connect: You have worked in multiple countries. Why has Thailand become a focal point? 

Forni: Thailand offers an enabling environment: strong interest from asset owners, active financial institutions, and a clear framework for greenhouse-gas crediting through the Thailand Greenhouse Gas Management Organization. We also have a very collaborative set of counterparts—led by the Department of Climate Change and Environment—working alongside utilities and regulators to align technical, legal, and financial pieces. Earlier work in Vietnam helped shape the model; Thailand provided the conditions to pilot the approach at scale. 

SIPET Connect: What are the key building blocks of the model? 

Forni: There are three pillars. First, off-balance-sheet delivery using performance-based contracts and standardized procurement. Second, a pathway for carbon crediting, so that verified emission reductions can be monetized. This provides a meaningful uplift to project returns. Third, a supportive market infrastructure: sandbox pilots, clear licensing where needed, and fit-for-purpose accounting and disclosure, so financial institutions can participate with confidence. 

SIPET Connect: What have you learned from working with industrial zones and service providers? 

Forni: Scale is achieved by standardization. When audits, contracts, and MRV are consistent across dozens or hundreds of sites, large firms and their ESCO subsidiaries can participate at volume, and smaller providers find opportunities through subcontracts. Equally important, we’ve clarified procurement and contracting pathways, so that public agencies can use shared-savings arrangements where appropriate—always in line with regulations and in coordination with the utilities. The through-line is collaboration and clarity, not one-offs. 

SIPET Connect: What does the initial Thailand pipeline look like, and how do carbon revenues fit in? 

Forni: Subject to the usual approvals, the current proposal includes a lending line through a partner bank with a significant share earmarked for physical investments. Early tranches prioritize rooftop solar across public buildings, LED streetlighting, and industrial-estate solar expansions. Together, these could deliver substantial electricity savings and measurable emissions reductions. Where issuing of carbon credits is appropriate, verified reductions can be sold forward—creating a steady revenue stream that improves project economics while maintaining a conservative approach to quantification and reporting. 

SIPET Connect: You mentioned sandboxing. What kinds of pilots are you exploring? 

Forni: I can give you two examples. On the finance side, we’re working with banking partners on underwriting verified emission reductions and piloting forward purchase contracts. On the market infrastructure side, we’re collaborating with the exchange on structured forward auctions. Everything is done transparently, within the relevant regulatory frameworks, and with careful attention to accounting and disclosure. 

SIPET Connect: What’s the appetite you are seeing from the private sector? 

Forni: It’s strong when the offer is clear. Asset owners want a short list of bankable options, indicative capex, expected savings, and a straightforward path to funding and delivery. We’ve held information sessions and are coordinating with banking associations so that lenders can approach their clients with standardized packages. Adding a well-governed crediting component can lift returns further, while standardized documentation brings transaction costs down. 

SIPET Connect: How portable is the approach across Southeast Asia? 

Forni: The toolkit travels, but the first steps differ by market. In some places, distributed solar leads; in others, energy efficiency or waste-to-energy pilots make more sense. We also collaborate closely with financial authorities—central banks, securities regulators, and finance ministries—so that solutions integrate smoothly with domestic financial systems. The aim is to complement ongoing efforts and help local institutions scale what already works. 

SIPET Connect: What makes you confident this can scale beyond a single country? 

Forni: We’re not betting on unproven technology. We’re assembling well-tested practices—shared-savings contracts, standardized MRV, forward procurement, and transparent crediting—into a coherent package that institutions can use. When the pieces are aligned, projects move quickly and reliably. That’s what gives us confidence in the model’s scalability. 

Clean energy events are proliferating across Southeast Asia, but few are deliberately designed to foster candid, peer-to-peer exchanges among those shaping national energy policies. The Regional Energy Transition Dialogue (RETD), organized annually under the project Clean, Affordable, and Secure Energy for Southeast Asia (CASE), aims to fill that gap.

For the past three years, the RETD has been convening political partners from Thailand, Indonesia, the Philippines, and Viet Nam for two to three days of discussion under the Chatham House Rule.[1] The RETD shows that purpose-driven convening is a strategic tool in its own right: by bringing together the right people, focusing on timely themes, and creating a trusted space, it enables Southeast Asian policymakers to share candidly, learn from one another, and take those lessons back home—creating impact that extends well beyond the event itself.

In this Transition Toolbox conversation, Peter du Pont of SIPET Connect speaks with Sascha Oppowa, Project Director at GIZ [Deutsche Gesellschaft für Internationale Zusammenarbeit] [SO1]  Thailand, about how the Regional Energy Transition Dialogue works, what makes it effective, and why purposeful stakeholder convening can be as powerful a tool as any technical intervention.

****

SIPET Connect: Sascha, could you start by describing your role at GIZ and the work you do related to the energy transition in the Southeast Asia region?

Sascha Oppowa: In my role as Project Director at GIZ, I have the pleasure of being responsible for overseeing the Clean, Affordable, and Secure Energy for Southeast Asia (CASE). CASE focuses on four countries—Thailand, Indonesia, the Philippines, and Viet Nam—and it has a regional component that supports the ASEAN [Association of Southeast Asian Nations] vision for a regional power grid. The project is implemented as a consortium, with GIZ in the lead, and local partners in each country, as well as two international partners based in Germany. Together, we combine research, dialogue, and capacity-building to support to advance a sustainable energy transition in the region. Besides this, we are also running this wonderful platform, The Southeast Asia Information Platform for Energy Transition (SIPET), to foster transparency and mapping in Southeast Asia.

SIPET Connect: The Regional Energy Transition Dialogue has become a core part of CASE. What is it, and what does it aim to achieve?

Sascha Oppowa: The Regional Energy Transition Dialogue, or RETD, is an exchange and learning platform that we have now organized for three consecutive years. Its purpose is twofold: first, to share state-of-the-art research and evidence on the energy transition—whether developed within CASE or contributed by other partners; and second, to create a safe, closed-door space for peer-to-peer exchange among government officials and key stakeholders from our four partner countries. What makes RETD unique is that these participants might not otherwise meet; it allows them to step outside domestic silos, learn from each other’s approaches, and discuss both successes and challenges. Over time, this has helped build trust and foster an atmosphere where candid conversations can take place, which is critical for advancing the region’s energy transition.

SIPET Connect: How do you curate the discussions and select the topics?

Sascha Oppowa: We have been experimenting with both the format and the content over the three events we have held so far. We have always linked the theme to our ongoing workstreams: the very first edition of the RETD was a trial run in the sense of testing whether the idea of bringing together partners from different countries in Southeast Asia to openly share perspectives and experiences would work as envisioned. Building on these learnings, the second year allowed us to refine the concept further, bringing everyone together under the theme of “Electricity Market Designs for Renewables”, which provided a more focused structure for exchange and collaboration.

This year’s theme for our RETD was geopolitical developments and their implications for national energy systems, and this generated strong engagement. Participants discussed issues such as supply chains for critical minerals, the role of China in the region, and the implications for energy security in their countries. Post-event feedback confirmed that the theme closely matched their priorities. More broadly, I believe this approach ensures participants receive up-to-date insights while also creating common ground for them to reflect on and compare their national experiences.

SIPET Connect: The Dialogue is held under the Chatham House Rule. Why is that important?

Sascha Oppowa: What has proven crucial is not so much the formal application of the Chatham House Rule itself, but rather the creation of a framework and shared understanding of how to design a space, an environment, and atmosphere that is conducive to open exchange—where participants feel at ease to speak and reflect together. Government officials and our political partners rarely have many opportunities to meet across borders in such a setting and to engage in candid conversations with one another. With the RETD, we seek to provide exactly this: a room that fosters trust, encourages the sharing of both achievements and challenges, and allows participants to recognize that many of their peers in other countries are navigating similar complexities in the energy transition.

SIPET Connect: What have been the key takeaways or outcomes from these dialogues?

Sascha Oppowa: The RETD is not designed to deliver immediate policy changes. The impact is often subtle but long-term. An official from Indonesia, for example, might hear how the Philippines is tackling a particular challenge and adapt that approach at home.

Two lessons stand out for me:

The first is that trust is built over time: you need repeated engagement to create the openness we now see in our RETD meetings.

The second is that shared challenges unite people: knowing that others face similar barriers makes cooperation easier and more natural.

SIPET Connect: With so many clean energy events in the region, how do you ensure the Regional Energy Transition Dialogue stands out?

Sascha Oppowa: For me it depends on the purpose of each event. Large conferences such as ADB’s Asia Clean Energy Forum (ACEF) are excellent for networking and broad thematic discussion. Our RETD, however, is designed very differently. It is highly targeted, limited to our political partners and key counterparts in each country, and the agenda is shaped around their specific needs and interests. That focus, combined with a closed-door setting, makes the discussions more relevant, candid, and ultimately more valuable for the participants. In that sense, I think RETD fills a unique niche rather than competing with broader events.

SIPET Connect: Could you describe the participant mix and how the sessions are structured?

Sascha Oppowa: We typically invite about 20 political partners—representatives from ministries, utilities, or government-linked agencies and a similar number from our CASE consortium, which includes local think tank partners and international experts.

We also bring in external speakers. This year, for example, the International Energy Agency’s Singapore office presented on topics such as grid flexibility and supply chain challenges. The Dialogue usually runs over two to three days. We would begin with scene-setting inputs from partners and experts, followed by breakout sessions and peer exchanges. This mix of evidence-based inputs and interactive dialogue creates both knowledge sharing and candid peer-to-peer conversations.

SIPET Connect: Have any new partnerships, initiatives, or changes emerged directly from the Dialogue?

Sascha Oppowa: I would not claim that the Dialogue leads directly to policy changes. However, it creates the relationships and shared understanding that make cooperation easier. Participants’ feedback has been overwhelmingly positive, especially this year, particularly on the value of connecting with peers from other countries whom they might not otherwise meet.

SIPET Connect: Was there anything from this year’s Dialogue that particularly stood out to you?

Sascha Oppowa: What stood out to me this year was how visibly the trust between participants across borders had grown over the course of the Dialogue. On the first evening, during an informal welcome, you could still see people clustering within their country groups. By the end of the two workshop days, those boundaries had broken down—participants from different countries were sitting together at lunch, engaging in breakout sessions, and sharing openly with each other. That shift is exactly what RETD is meant to achieve: moving beyond national silos and creating genuine peer-to-peer exchange. Seeing that transformation unfold in just a couple of days was very rewarding.

SIPET Connect: Looking ahead, what is your vision for the Regional Energy Transition Dialogue in 2026 and beyond?

Sascha Oppowa: As CASE, we would like to hold at least one more Dialogue next year. After three years, I am confident we have found a formula that works: relevant themes, a trusted space, and a strong team to deliver it.

Beyond CASE, I would be happy to see the concept and format adapted elsewhere – but would think this is not necessarily easy to replicate. Building the trust we have now took years of day-to-day work with partners in each country. Without that foundation, the openness we see at the Dialogue, I could imagine it being difficult to achieve.

As Southeast Asia scales up its energy transition, understanding the landscape of energy investments is more important than ever. Across the region, governments, development partners, and philanthropies are implementing hundreds of energy transition projects amounting to billions of dollars in technical assistance and investment. This raises two important questions for us: 

1. Are these efforts aligned, effective, and reaching the right places?   

2. And is it possible to avoid the inevitable overlap between donor activities in the Energy Transition space? 

To help answer these questions, the Southeast Asia Information Platform for the Energy Transition (SIPET) recently completed an update of its flagship Project Mapping Tool. The result: a refreshed, regional view of more than 480 projects and more than USD 45 billion in clean energy investments—much of it focused on technical assistance and capacity building. 

But this is more than a numbers exercise. The updated data provides insight into regional progress on the energy transition, technical and programmatic opportunities for greater collaboration, and the significant benefits of making energy transition efforts more visible and coordinated. This article highlights lessons from SIPET’s latest donor mapping effort and argues that a more collaborative, shared approach to data on donor assistance can reduce duplication and help accelerate Southeast Asia’s transition. 

Why Project Mapping Matters 

The energy transition is not about just infrastructure. It’s also about technical assistance to build capacity, and the need for an efficient, collaborative and coordinated approach. With growing interest from funders and implementers, there’s a clear need for a shared platform that can track activity, identify synergies, and make information accessible to all stakeholders in the energy transition. 

The SIPET Project Mapping Tool helps meet this urgent need. The tool covers projects in Indonesia, the Philippines, Thailand, and Viet Nnam and provides a user-friendly way to understand what types of activities are under way, where resources are flowing, and where support may still be needed. 

Our recent update was not just technical. It also had a strategic objective—aiming to build trust, transparency, and a shared understanding and knowledge base among energy transition stakeholders in Southeast Asia. 

Figure 1. Projects in the SIPET Project Mapping Tool by Country and Project Status 

What the Data Show 

While the scale and pace of energy transition activities is accelerating, the updated SIPET mapping reveals a few key takeaways: 

1. Funding at both the national and regional levels is becoming more transparent. Based on more than 480 projects recorded on SIPET (excluding JETP), most of the budget has been implemented in Indonesia; followed by projects with a regional remit; followed by projects focused on the Philippines, Viet Nnam, and then Thailand.  

2. Apart from the Just Energy Transition Partnership (JETP) funding, investments can be grouped into two broad areas:  

a) projects related to renewable energy (RE) Infrastructure and variable renewable energy (VRE); and 

b) support for policy advocacy, technical assistance, and capacity building. 

Figure 2. Budget share by theme: Policy Advocacy, Technical Assistance & Capacity Building, Infrastructure Investment, and JETP across 481 energy projects in Indonesia, the Philippines, Thailand, and Vietnam. 

Figure 3. The budgets of the three project themes recorded in SIPET, broken down by country. 

c) Overall, more than USD 15 million of funds recorded in SIPET are directed toward policy advocacy, technical assistance, and capacity-building initiatives, while more than USD 13 million are directed toward infrastructure. Infrastructure development in Indonesia, Viet Nnam, and Thailand accounts for a larger share of funding compared to funding for policy advocacy, technical assistance, and capacity-building projects, while the opposite trend is observed at the regional level and in the Philippines.  

d) Strong collaboration is essential to enhance public awareness, support planning, and strengthen accountability. For example, through collaboration with local partners, the commitment of USD 15 billion in energy-climate funding under JETP is transparently recorded and presented on SIPET. 

An important potential benefit of the SIPET Project Mapping tool is that it can identify opportunities to strengthen donor alignment, improve the completeness and availability of data, and expand focus to emerging priorities such as a Just Transition, inclusive financing, and subnational implementation. 

What We Learned from the Process 

Behind the updated numbers lies a significant effort to compile and validate project data from dozens of sources. Through this process, several lessons emerged: 

1. Structured, accessible data enables faster updates and better visibility. Where donors and partners provided well-organized project lists or shared database links, integration into the SIPET tool was quicker and more accurate. 

2. Manual data entry is still needed in many cases, particularly where information is not readily available online. While tools like web scraping and translation helped streamline some parts of the process, human verification remains essential. 

3. Donor collaboration makes a difference. The participation, and sharing of data by, donor coordination groups such as the Vietnam Energy Partnership Group (VEPG) demonstrates how strong engagement can lead to better regional insights and easier data integration. 

These lessons point to a shared opportunity: if donors and partners can align around simple data-sharing practices, everyone benefits from clearer insights and more informed decision-making. 

For Donors: Why Contributing to SIPET Matters 

The Project Mapping Tool is designed as a supportive platform for donors, not an evaluation tool. By participating, donors gain: 

1. A neutral, regional space to share and visualize their contributions 

2. Improved visibility of their work alongside peers and partners 

3. The ability to identify alignment opportunities and avoid duplication 

4. Assistance in presenting and communicating project data, reducing the need for internal resources to create their own visualizations and summaries. 

Rather than build separate tools or websites, donors can use SIPET to complement their communications and reporting efforts, while contributing to a stronger regional ecosystem. 

Conclusion: From Fragmentation to Shared Purpose 

Southeast Asia’s energy transition is dynamic, diverse, and full of opportunities. With more than 480 projects mapped, the SIPET Project Mapping Tool offers a snapshot of progress and a foundation for greater collaboration. 

We invite donors, implementers, and partners to explore the map, share your projects, and be part of building a more transparent, inclusive, and effective energy transition.

Rising energy demand, rapid urbanisation, growing populations, and shifting geopolitical dynamics are placing immense pressure on Southeast Asia’s energy systems. The need for secure, affordable, and sustainable energy has never been more urgent. The International Energy Agency (IEA), a central force in shaping global energy policy — has responded by establishing its first Regional Cooperation Centre outside of Paris, choosing Singapore as its base. 

In this edition of SIPET Connect, Maximilian Heil, Project Coordinator CASE at GIZ, speaks with Sue-Ern Tan, the Head of the IEA Regional Cooperation Centre, about the Centre’s strategic priorities, the evolving nature of energy security, and how Southeast Asia can shape a secure, affordable, and sustainable clean energy future through regional collaboration.  

In this conversation, Sue-Ern Tan offers a front-row view of how multilateral institutions are rethinking their role—working more directly with countries, gathering region-specific data, and enabling cross-border solutions like power trade and clean energy financing. IEA’s move to establish a regional hub in Singapore signals a shift from its global advisory role to one that also builds local and regional partnerships. With energy transitions gaining urgency and complexity, Southeast Asia needs not just capital and technology, but coordination and capacity. This new Centre aims to deliver exactly that—embedding support where it’s most needed, and making sure the region’s voice is heard in shaping the global energy agenda. 

**** 

SIPET Connect: To begin, could you briefly introduce yourself and your role at the IEA? 

Sue-Ern Tan: I’m the Head of the IEA’s recently-opened Regional Cooperation Centre in Singapore. This is the IEA’s first office outside of its headquarters in Paris, and it serves as a platform to deepen our collaboration across Southeast Asia. While we have a broad global mandate, our initial focus here is clearly on ASEAN — supporting countries in the region to navigate the challenges and opportunities of the clean energy transition. 

SIPET Connect:  The IEA has long played a key role in global energy governance. How has its focus evolved in recent years, particularly in light of energy security concerns and the global emphasis on the clean energy transition? 

Sue-Ern Tan: The IEA was established over 50 years ago to coordinate collective responses to oil supply disruptions among member countries. That mission remains relevant — we activated those emergency response mechanisms most recently after Russia’s invasion of the Ukraine and the subsequent energy crisis in 2022. But the world has changed dramatically over the course of the IEA’s history. 

Today, the IEA works across all fuels and technologies, supporting governments and industry to build sustainable, affordable, and secure energy systems. For example, at the Global Summit on the Future of Energy Security, which we co-hosted with the UK Government in April, two major themes emerged: first, that energy security is no longer just about oil and gas but includes critical minerals, supply chains, and electricity system reliability; and second, that multilateral cooperation is more essential than ever.  

SIPET Connect: Why was Southeast Asia chosen for the IEA’s first regional office — and why Singapore specifically? 

Sue-Ern Tan: Southeast Asia is a fast-growing region and a major driver of global energy trends. In fact, the region is expected to account for around a quarter of future global demand growth, second only to India. What’s more, eight out of the ten ASEAN member states have committed to net-zero targets. So, the region is both strategically important and full of potential. 

Having this regional presence allows us to work much more closely and responsively with countries on the ground and Singapore is very well-located to access the rest of the region. 

SIPET Connect: What are the key objectives and priority areas for the Regional Cooperation Centre in Singapore? 

Sue-Ern Tan: We focus on three core thematic areas: 

First, we assist efforts to accelerate renewable power and cross-border power trade — particularly through support for the ASEAN Power Grid and guidance on how to integrate variable renewables.  Second, we work on the scaling up of clean energy technologies — including hydrogen, ammonia, CCS, nuclear, and innovations related to AI and data centre demand.  And finally, we provide analytical support for efforts to unlock finance for clean energy—notably through work like our Cost of Capital Observatory, which identifies region-specific barriers to investment. 

And then, underpinning all of this, we work in the areas of capacity-building and development partnerships.  We engage with partners in the region on capacity building and training, especially for Southeast Asian policymakers and regulators across many different topics; and we also work through partnerships and the convening of events, to help align efforts across institutions and stakeholders in the region. 

SIPET Connect: How does your work in the Regional Cooperation Centre complement the efforts of the IEA’s work more globally? 

Sue-Ern Tan: It’s very much a joint effort. The Regional Cooperation Centre is small—just five people—but we’re fully integrated into the broader IEA network. We collaborate closely with the analytical teams in headquarters, whether on global energy modelling, data, or market and policy insights. 

For instance, the IEA’s upcoming Global Hydrogen Report will feature an ASEAN-specific deep dive. Our role is to gather the most accurate and regionally relevant data, ensuring that Southeast Asia’s developments are reflected in global discourse. We lead regional projects and analysis while also feeding those regional insights back into the IEA’s global work. We are also building on the already excellent work happening at the IEA to deliver more efficiently and effectively in this region.   

SIPET Connect: Where do you see the biggest opportunities for accelerating the clean energy transition in Southeast Asia? 

Sue-Ern Tan: A connected regional power grid is absolutely essential for Southeast Asia, where electricity demand is growing faster than anywhere else. Interconnections will allow countries to move electrons more efficiently, match supply to demand centres, balance variable renewables, and unlock cross-border trade. 

Financing poses a significant barrier, particularly for interconnections, which is why IEA is preparing a report focused on how to mobilise investment in this area. Political will is also crucial, especially at the bilateral level, to align technical and regulatory frameworks across borders. 

We recognise the need to address a range of topics to help countries achieve their energy transition goals. Energy efficiency is the primary fuel and we have a large work programme in Southeast Asia focusing on accelerating efficiency across buildings, appliances, transport, and industry. The region’s key role as a manufacturing hub with excellent technological and natural resource potential is also a key opportunity to encourage the development of a variety of energy supply chains and technologies from solar and wind to hydrogen and batteries.  

Finally, we at the IEA understand the critical importance of data. It underpins effective policy making and we have seen how eager countries in this region are to enhance their capacity on data and energy statistics in order to help shape and measure their transition goals.   

SIPET Connect: Collaboration is key in scaling up the energy transition. Who are the IEA’s key partners in the region, and what are some upcoming areas of focus? 

Sue-Ern Tan: We work closely with regional bodies like the ASEAN Centre for Energy (ACE) and the ASEAN Secretariat and all of their member states, as well as multilateral organisations including UN ESCAP, ADB, World Bank, and UNOPS-ETP. Our engagement extends to various regional governments and local contacts, including embassies and development partners. There are a number of active philanthropies, think tanks, NGOs, academic institutions and others which are both local and regional doing really interesting and important work as well. The new regional centre is looking to build new and continue long-established trusting and collaborative relationships. Our goal is to complement, and not to duplicate, existing initiatives.  

For example, we collaborate with UNESCAP on capacity development for regulators, and with the project CASE on the Regional Energy Transition Dialogue. We’re always asking: Where can the IEA add the most value? 

We also work based on demand from countries. For example, we collaborate with Southeast Asian countries to understand their energy goals, what it is they need to achieve those goals and where the IEA is best equipped to support. 

SIPET Connect: What are the biggest challenges in achieving a just energy transition in Southeast Asia? 

Sue-Ern Tan: From an equity standpoint, one ongoing challenge is energy access—not just whether electricity reaches people, but whether it’s reliable, clean, and affordable. Clean cooking is another area that deserves more attention in this region, particularly for women and rural communities. 

Fossil fuels will remain part of the mix for some time. The question is: how do we manage the energy transition responsibly? How do we support affected communities, improve methane management, and ensure fairness in job transitions? 

The IEA recently helped launch a Global Commission on People-Centered Clean Energy Transitions, which encourages countries to embed social equity, access, and participation into their transition strategies. We’re working to bring those principles into this region’s policy frameworks. 

SIPET Connect: How can platforms like SIPET and regional partnerships contribute to addressing barriers to transition? 

Sue-Ern Tan: Platforms like SIPET are vital for promoting transparency and open access to data and research, supporting knowledge transfer and capacity building, and bridging the gap between analysis and action by helping stakeholders move from policy aspiration to implementation. 

Ultimately, no single actor can drive the energy transition alone. Practical, inclusive, and collaborative efforts are key to make the energy transition real on the ground. We must build on the existing work of partners and make sure we are providing the most impact for countries in this region. 

SIPET Connect: Finally, what message would you like to share with SIPET’s community of energy transition professionals? 

Sue-Ern Tan: Keep going. The scale of both the opportunity and the challenge in Southeast Asia is immense. Success here is not optional; it’s essential for the global energy transition. 

But let’s also remember: a successful energy transition isn’t just about hitting emissions targets. It must also make energy more secure, more affordable, and more reliable. If we keep those pillars in mind, we’ll be better equipped to build transitions that truly work—for governments, people, and businesses.
