Battery storage could be a short-term solution to the national grid’s limitations, which pose a major challenge to expanding renewable generation.
Sri Lanka Sustainable Energy Authority Director General Rohana Rambodage said this at an event in Colombo on Tuesday (13).
The country aims to generate 70% of its electricity from renewable sources by 2030 and achieve net-zero emissions by 2050.
Meeting those targets requires solutions to manage the intermittent nature of renewable generation and ensure a reliable supply. Upgrading the grid remains necessary, but would take considerable time, while grid-connected storage offers a faster way to address some of these challenges.
Rambodage highlighted the country’s renewable potential, including hydropower, solar, wind and biomass. Solar offers considerable opportunities because of year-round sunlight.
However, solar generation is concentrated during daylight hours, while demand continues into the night, including peak-demand periods. Battery systems can store excess daytime electricity and release it at night, helping balance supply and demand.
He said battery storage could also improve grid stability, reduce dependence on imported fossil fuels and lower greenhouse gas emissions. It could create jobs and support domestic solar equipment-related industries.
Product quality and safety must remain key considerations as the technology evolves, he stressed. Proper attention should be given to electrical isolation, surge protection and voltage variations.
He described battery storage as an important step towards strengthening energy security and the transition to sustainable energy. He expressed hope that the initiative would encourage developers, businesses and households to adopt the technology.
