A key feature of the Capella Solar project is the integration of a 3 MW/1.9 MWh battery energy storage system (BESS). This technology enhances grid stability and ensures a consistent power supply, addressing the intermittency challenges of renewable energy.
[pdf] Rivi Danavi Private Co., a joint venture between Lakdhanavi Ltd. and WindForce PLC, is implementing the project. Work will also include a 12 MWh battery storage facility, 132 kV transmission system and 132 kV grid substation. The project is scheduled for completion within the first quarter of 2027.
[pdf] The project establishes Sri Lanka’s largest non-government-funded battery energy storage system (BESS), powered by solar photovoltaic (PV) technology. The Battery Commissioning Event took place on 24th of July 2024 at the Watch Tower Sri Lanka headquarters.
