Sri Lanka approves new renewable feed-in tariffs and battery storage rates

PUCSL’s tariff table covers small-scale renewable plants below 10 MW, rooftop prosumers and systems equipped with battery energy storage. Reported rates include LKR 15.81/kWh daytime payments for systems above 250 kW, with nighttime BESS rates of LKR 45.53/kWh for 250 kW to 1 MW installations and LKR 42.49/kWh for systems above 1 MW during the first 15 years. The structure matters because it explicitly values dispatchable renewable output rather than treating batteries as an add-on without a bankable tariff.
