The Ceylon Electricity Board (CEB) announced significant progress in the development of the Maha Oya Pumped Storage Hydropower Project, Sri Lanka’s first-ever “water battery.”
This innovative 600 MW project is designed to store excess renewable energy from solar and wind sources, bolstering grid stability and supporting the nation’s ambitious target of generating 70% of its electricity from renewable sources by 2030.
Located in Aranayake and Nawalapitiya, the project will use two reservoirs connected by a 2.5 km tunnel, effectively operating as a large-scale energy storage system.
By storing surplus energy during low demand and releasing it when needed, the system will reduce reliance on fossil fuels and lower carbon emissions, marking a major step toward a sustainable energy future for Sri Lanka.
At a recent meeting, international development partners were introduced to the project’s financial roadmap, with CEB aiming to secure long-term funding from global agencies.
This approach seeks to minimize the impact on electricity tariffs, ensuring affordability for consumers while advancing renewable energy integration.
The Maha Oya project is expected to provide crucial support for renewable energy absorption into the grid, fostering economic growth, job creation, and environmental sustainability.
CEB has called on all stakeholders to support this initiative, as the country moves closer to energy independence and a greener, more resilient future.
