The Cabinet of Ministers has approved the award of tenders for the installation of independent battery storage systems at 16 electrical substations across Sri Lanka, a major step towards maximising the utilisation of solar energy in the national electricity grid.

The approval follows the submission of a General Board Memorandum by Power Minister Eng. Kumara Jayakody, highlighting the need for battery storage to address one of the key challenges in integrating renewable energy into the power system. Under the Government’s program, a total of 10 MW/40 MWh battery systems will be installed at each substation, totalling 160 MW/640 MWh nationwide.

A statement issued by the Ministry noted that the tenders for the project were initially invited on 30 July 2025, with the opening scheduled for 16 September 2025. Due to high interest, the tender period was later extended to 14 October 2025, resulting in 153 submissions for the 16 grid substations.

The Cabinet approval was granted on 2 January following the recommendations of the Independent Tender Committees, which reviewed all technical and other specifications applicable to each site.

“The project will be implemented under the Build, Own, and Operate (BOO) model, in line with the Cabinet decision taken on 28 April 2025,” the statement noted.

The battery storage systems are expected to enhance grid stability, allow better integration of solar power, and help optimise electricity supply from renewable sources, marking a significant milestone in the country’s renewable energy expansion.
