Revera Energy has announced that construction will commence immediately on its 200MW/400MWh Windyhill battery energy storage system (BESS) project near Glasgow, following the successful achievement of financial close.
Windyhill marks Revera’s first UK BESS project to reach financial close. According to the company, it also has an additional 800MW/1,600MWh of BESS projects in the United Kingdom with approved planning consents, secured land rights and grid access, as well as 15-year capacity contracts. Construction across all three projects is expected to begin within the next 12 months.
Financial close for Windyhill BESS was achieved through non-recourse senior debt financing provided by Santander CIB. International law firm White & Case served as borrower’s counsel.
Revera has also secured a 10-year revenue floor agreement with Danske Commodities, covering 100% of the project’s capacity. Under the agreement, Danske Commodities will deliver trading and optimization services, while Revera will oversee construction management and long-term asset management.
Energy storage technology for the project will be supplied by GE Vernova, which will also provide a long-term service agreement. G2 Energy has been appointed as the balance of plant contractor and maintenance provider. Windyhill BESS is expected to enter commercial operations in the first quarter of 2028.
Once operational, the project will support one of the most grid-constrained areas in Great Britain. The site is located near significant wind generation capacity north of the B6 boundary — a 400kV transmission bottleneck between Scotland and England — positioning the system to play a key role in alleviating network congestion and enhancing grid flexibility.
Daniel Kim, CEO of Revera Energy, described the financial close as a major milestone. “Achieving financial close for Windyhill is a significant accomplishment and marks another crucial step in our mission to build a high-quality independent power platform in the UK and Australia and accelerate the energy transition,” he said.
Revera Energy was founded in May 2025 by global investment management firm The Carlyle Group. The company is developing multiple BESS projects across the United Kingdom and Australia. In Australia, Revera expects the 150MW/300MWh Stage 1 segment of its Bungama BESS to begin commercial operations in the second quarter of 2026.
The company’s progress in both markets follows the recent expansion of a US$150 million credit facility with Japanese investment bank Nomura, further strengthening its financial capacity to scale its energy storage portfolio.
