Sri Lanka has launched an international tender for a large-scale battery energy storage project aimed at strengthening the country’s power grid, the Board of Investment (BoI) said.
The National System Operator (Pvt) Ltd, under the Ministry of Energy, has opened international competitive bidding to establish a 250 MW/1000 MWh standalone battery energy storage system, structured as 10 MW/40 MWh AC-capacity projects across 25 grid substations island-wide. The project will be developed on a build, own and operate (BOO) basis under a 15-year energy storage agreement, with connection at 33kV.
The substations earmarked for the systems include Ambalangoda, Ampara, Bolawatta, Chunnakam, Hambantota, Kurunegala, Matara, Galle and Monaragala, among others. The BoI called it “a significant opportunity for global and local developers to participate in Sri Lanka’s energy storage transition and support grid stability as the country scales up renewable integration.”
Request-for-proposal documents will be available until August 13, with the proposal submission deadline set for 10:00 a.m. on August 14.
The tender is the latest step in Sri Lanka’s push to add utility-scale storage to its grid. The country has been rolling out battery systems to firm up renewable supply as it targets 70% renewable generation by 2030, shifting surplus daytime solar and wind output to cover evening peak demand.
