State utility PLN and renewables company Sembcorp will develop Indonesia’s first co-located solar PV and battery energy storage system (BESS).
The 50MW solar plant and 14.2MWh BESS project will power Indonesia’s future capital city Ibu Kota Nusantara (IKN) on the island of Kalimantan.
As well as being the country’s first co-located solar-BESS project, it is also the first renewable energy project to be developed and financed for Indonesia’s new capital.
Covering 87 hectares, the plant will produce an estimated 92.8GWh renewable energy for IKN.
The site features 114,420 625MWp bifacial solar PV modules and 126 lithium iron phosphate battery packs, as well as 200kW and 300kW inverters and PV smart transformer stations.
Through its subsidiary PLN Nusantara Power, PLN is the majority owner of the project, which is being developed jointly with Sembcorp.
PLN is also the offtaker of the project. Singapore-based Infrastructure Credit Platform Clifford Capital and SocGen acted as lenders.
Watson Farley & Williams advised PLN on the development and financing of the project.
