entral Java has started the construction of Gajah Mungkur floating solar farm in Wonogiri regency worth Rp 1.6 trillion (US$9.03 million), with a capacity of 134.2 megawatts peak (MWp), or 100 megawatts alternating current (MWac).
The Gajah Mungkur floating photovoltaic (FPV) system is one of the strategic projects in a national program to develop 100 GWp in three years. Targeted to start operations in 2027, the floating solar farm is projected to produce some 218 gigawatt-hour (GWh) per year.
The solar farm development was designed with consideration for Gajah Mungkur Dam’s functions and nearby public activities.
The total area of the solar cells will be less than 5 percent of the dam’s total area of 5,600 hectares. Solar cell placement is also prepared by calculating changes in water level and preserving residents’ and fishermen’s transport routes.
Gas-fired power plant operations director at PT PLN Indonesia Power, Daniel Eliawardhana, said currently preparation and construction technical aspects were ongoing.
“The floating solar farm is expected to be operational by the end of 2027 producing 134 MWp,” he said.
The Gajah Mungkur FPV system is not the only solar power project being carried out in Central Java. The government also plans to construct a floating solar farm in Kedung Ombo Dam with a capacity of 100 MWac while Karimunjawa Islands is preparing a floating solar farm with a capacity of about 7.4 MW.
