Java-Bali 500 kV Power Transmission Crossing Project Dates: January 2013 - December 2020

PROJECT OBJECTIVE

The proposed investment project will strengthen the Java-Bali power transmission grid by constructing 220 km of extra high voltage transmission lines with associated substations. The project forms part of the governments regional economic development master plan and its long-term power development plan. The project will benefit the population in Bali by meeting future demand growth in Bali Island, thus ensuring long-term power supply security to support sustained socio-economic growth and government plan to achieve 90% electrification by 2020.

PROJECT DESCRIPTION

The project will strengthen the power transmission system by connecting Bali with a 500 kV link to Java, thus facilitating efficient utilization of existing and planned power generation plants in Java. This would enable transmitting comparatively cheaper power to Bali from the large power plants in East Java. Currently PLN relies mainly on expensive diesel-based generation to supply electricity in Bali and the proposed transmission line will reduce operational expenditures which will also reduce the subsidy payments made to PLN by the government. PLN's investment in the project is also part of its nationwide plan to increase electrification. The upgrading of the 150/20 kV substations under the project along the proposed route of the transmission line also ensures provision of electricity among the local rural communities in the project area.
