July 02, Colombo (LNW): Sri Lanka is preparing to roll out a 250-megawatt battery energy storage system as part of efforts to enhance the stability and efficiency of the national electricity network.
The project, which will be linked to solar power generation, is expected to be installed at 19 substations across the country, providing additional capacity to store electricity generated during peak production periods and release it when demand is higher.
Chairman of the National Transmission Network Service Provider (Private) Limited, Dr Pradeep Perera, said the initiative is designed to strengthen grid reliability while supporting the country’s transition towards greater use of renewable energy.
He explained that the battery storage system would help reduce dependence on diesel-powered electricity generation, particularly during periods of high demand or when renewable energy output fluctuates. This is expected to lower fuel consumption and improve the overall efficiency of the power sector.
According to Dr Perera, the reduction in fuel costs could also generate long-term financial benefits for the electricity sector. If operational savings are sustained, they may create opportunities for future consumer relief, including the possibility of more favourable electricity tariffs.
The project forms part of Sri Lanka’s broader strategy to modernise its energy infrastructure, improve energy security and increase the contribution of renewable sources to the national grid as the country works towards a more sustainable power sector.
