WindForce Boosts Renewable Portfolio to 268 MW with Battery Storage and Floating Solar
COLOMBO, September 18, 2026 — Renewable energy producer WindForce PLC has expanded its total generation capacity to approximately 268 MW following the commissioning of two new clean-energy projects, including what the company describes as Sri Lanka’s first standalone grid-scale battery energy storage system.
According to a disclosure made to the Colombo Stock Exchange (CSE) today, the company commissioned a 10 MW / 40 MWh Battery Energy Storage System (BESS) in Anuradhapura alongside a new 5 MW floating solar power plant.
First Grid-Scale Battery Storage Project
The newly commissioned battery storage facility in Anuradhapura was developed through StoreX (Pvt) Ltd, a joint venture between WindForce PLC and Vidullanka PLC.
The project represents the first of 13 planned battery energy storage facilities that are expected to collectively provide 130 MW / 520 MWh of energy storage capacity to Sri Lanka’s electricity grid.
The initial project award for the Anuradhapura installation was disclosed by WindForce in May 2026.
Grid-scale battery storage can play an important role in supporting renewable energy integration by storing electricity and making it available to the grid when required.
Floating Solar Plant Adds New Capacity
At the same time, WindForce commissioned a 5 MW floating solar power plant developed by Diyajanani (Pvt) Ltd, a wholly owned subsidiary of WindForce PLC.
The project is expected to generate approximately 9 GWh of clean electricity annually.
The company’s execution of the Standardised Power Purchase Agreement (SPPA) for the floating solar project was previously disclosed in November 2025.
Renewable Portfolio Reaches 268 MW
With the commissioning of the two projects, WindForce PLC’s total renewable energy generation portfolio has increased to approximately 268 MW.
The latest developments strengthen the company’s presence in Sri Lanka’s renewable energy sector while also adding battery storage technology and floating solar generation to its portfolio.
The commissioning of the projects comes as Sri Lanka continues to expand renewable energy capacity and explore technologies that can improve the integration and reliability of renewable power within the national electricity system.
