Six project companies of WindForce PLC have submitted winning bids to build 28.25 megawatts and 143.75 megawatt-hours of battery energy storage, the renewable energy firm told the Colombo Stock Exchange on Friday.
WindForce’s estimated equity investment across the six projects is about Rs. 944 million, EconomyNext reported, citing a regulatory filing.
Bolted on to existing solar plants
The bids were placed under a tender to establish 150MW / 600MWh of battery energy storage integrated with existing ground-mounted solar power plants, on a Build, Own and Operate model over a 15-year operational period.
Pairing storage with solar plants already on the grid addresses the central problem of Sri Lanka’s solar build-out: output peaks at midday, while demand peaks after dark. Storage shifts the surplus into the evening rather than curtailing it.
The six units and their shareholdings are:
| Company | WindForce stake | Capacity |
|---|---|---|
| Diya Janani (Pvt) Ltd | 100% | 3.75 MW / 18.75 MWh |
| Kebitigollewa Solar Power (Pvt) Ltd | 88.50% | 4.90 MW / 25.00 MWh |
| Vydexa (Pvt) Ltd | 76.13% | 4.90 MW / 25.00 MWh |
| Solar Universe (Pvt) Ltd | 50% | 4.90 MW / 25.00 MWh |
| Sooryashakthi (Pvt) Ltd | 50% | 4.90 MW / 25.00 MWh |
| Solar One Ceylon (Pvt) Ltd | 50% | 4.90 MW / 25.00 MWh |
The six together account for 28.25MW and 143.75MWh — roughly 19% of the tendered capacity.
Award still pending
WindForce stressed that the formal award has not yet been made, confirming only that its project firms’ bid prices fell within the winning bid threshold.
“While the formal award of the projects is still pending, the Board of Directors considers this development to be price-sensitive information, given its relevance to the Company’s future operations, potential project portfolio expansion and long-term financial outlook,” the filing said.
The company cautioned that the disclosure “contains forward-looking statements based on the current bidding outcome” and remains subject to the final awarding process, regulatory approvals and execution of the relevant agreements.
Context
The tender is one strand of a broader storage push. Sri Lanka is targeting 960MW of battery capacity by mid-2027, and the first grid-scale facilities have already come online — WindForce and Vidullanka commissioned the country’s first BESS facility earlier this month, followed by commissioning across 16 sites.
Not reported
EconomyNext does not name the tendering authority, give the bid prices or tariff, say when awards will be issued, or identify which solar plants the six systems attach to.
