🔋 Sri Lanka Launches Mega 250 MW/1000 MWh Battery Storage Tender to Boost Renewable Grid

The National System Operator (NSO) has opened international competitive bidding for a Standalone Battery Energy Storage System (BESS), marking one of the country's largest grid-connected storage procurements to date. • Project Details & Structure: The tender calls for developers to Build, Own, and Operate (BOO) 10 MW/40 MWh capacity blocks across 25 grid substations island-wide (including Hambantota, Kurunegala, Chunnakam, and Galle). Successful bidders will sign a 15-year Energy Storage Agreement at the 33kV voltage level. • Requirements & Deadlines: Developers must finance, construct, and maintain the projects, including grid interconnection costs. Proposals are due by 10:00 hrs on August 14, 2026. RFP documents cost LKR 150,000 for local or USD 500 for overseas proponents. • Strategic Alignment: The initiative supports Sri Lanka's National Energy Policy targets to achieve 70% electricity generation from renewable sources and reduce imported fossil fuel dependence below 50% by 2030. It also aligns with the Ministry of Environment's Carbon Net Zero 2050 Roadmap. • FDI & Market Context: Globally, storage capacity grew 40% YoY in 2025 (adding 108 GW), per the IEA. Industry observers note that a stable, storage-backed renewable grid is critical for attracting Foreign Direct Investment (FDI), especially from multinational manufacturers (like RE100 members) who demand renewable-powered supply chains.
