October 14, Colombo (LNW): In a move aimed at advancing Sri Lanka’s renewable energy capabilities, the government has given the green light to a time-sensitive tariff system designed specifically for battery energy storage systems paired with rooftop solar installations.
According to an official statement from the Ceylon Electricity Board (CEB), the newly approved framework will see electricity stored in batteries and supplied to the grid during peak evening hours—between 6:30 p.m. and 10:30 p.m.—purchased at a rate of Rs. 45.80 per kilowatt-hour.
This is expected to provide a strong financial incentive for solar energy producers to invest in battery storage infrastructure.
It is designed not only to reward efficient energy storage and timely contribution to the national grid but also to ease the strain on conventional power plants during high-demand periods.
By enabling households and small-scale producers to store excess energy generated during daylight hours and release it during the evening peak, the scheme is expected to play a critical role in reducing the country’s reliance on fossil fuel-based power generation—especially costly thermal energy imports.
