Active Development Project
Hambantota BESS Development
Two 10 MW / 40 MWh Battery Energy Storage System projects near Hambantota Grid Substation, delivering grid-connected storage at 33 kV to strengthen southern Sri Lanka's power network.
Project Overview
Two utility-scale BESS projects at a critical grid location.
The Hambantota BESS Development is Skylis Lanka Power's current strategic priority. The project comprises two independent Battery Energy Storage Systems, each rated at 10 MW / 40 MWh, planned for development near Hambantota Grid Substation in Sri Lanka's Southern Province.
10 MW / 40 MWh per project
Each BESS project is rated at 10 megawatts of power output and 40 megawatt-hours of energy storage, providing 4-hour duration discharge at full capacity for grid support applications.
Hambantota Grid Substation
The projects are sited near Hambantota Grid Substation in Sri Lanka's Southern Province, a strategically significant location for southern grid reliability and expanding industrial demand.
33 kV grid connection
Both projects are designed for interconnection to the Ceylon Electricity Board's 33 kV distribution network, enabling direct integration with the existing substation infrastructure.
Strategic Significance
Why Hambantota — and why now.
Sri Lanka's Southern Province is experiencing growing electricity demand driven by expanding industrial activity and infrastructure development. The Hambantota area, home to a major port and industrial zone, represents a strategic point for reinforcing the southern grid.
Battery storage at this location can absorb renewable generation during surplus periods, reduce transmission losses by providing local storage, and deliver fast-response grid support that protects critical infrastructure and industrial operations.
Two projects at 10 MW / 40 MWh each will collectively provide 20 MW / 80 MWhof storage — a meaningful contribution to Sri Lanka's national energy storage capacity and its target of increasing renewable generation.
