State-owned electricity giant PLN plans to replace 200 old diesel-fired power plants (PLTD) with solar power stations (PLTS) to lower electricity production costs and bump up clean energy usage. PLN mega projects director Ikhsan Asaad said on Monday that building the stations, whose combined capacity was 225 megawatts (MW), would cost an estimated Rp 100 trillion ($6.83 billion) over the next two years. “That is huge money,” he told reporters at an online press conference. He added that the stations, which will power remote towns and villages, would be equipped with battery packs.

PLN planned to conduct project biddings in December and have the 200 stations operational by 2022, he said. Read also: Government studies plant to convert old power plants into rene...
