ISSUE

Java-Bali transmission and distribution system's limited capacity to transmit additional power.

Power shortages have been a critical infrastructure bottleneck throughout Indonesia and fast-track generation programs are being implemented to improve power generation capacity. Transmission and distribution networks need to be developed in a coordinated manner to realize the benefits of new generation capacities and to provide access to un-electrified areas. Bali is Indonesia's top tourism showpiece. However, the Bali power system suffers from frequent outages and blackouts due to low generation reserve margin and transmission bottlenecks. Transmission of power from East Java to Bali at 500 kV level was determined as the best option to improve the power supply in Bali based on power system studies and was included in PLN's power development plan. PLN's investment in the project was also part of its nationwide plan to increase electrification.

SOLUTION

Increased capacity through 220 km of extra high-voltage transmission lines with associated substations.

The investment project aimed to strengthen the Java-Bali power transmission grid by constructing 220 km of extra high-voltage transmission lines with associated substations. The project formed part of the Indonesian Government's regional economic development master plan and its long-term power development plan. It aimed to 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 the government's plan to achieve 90% electrification by 2020.
