Gore Street Energy Storage Fund chooses EDF for battery optimisation of new 80MW asset

By EDF | Posted August 03, 2023
  • Gore Street Energy Storage Fund has selected EDF to optimise new 80MW battery asset.
  • The energisation process for Stony, located in Milton Keynes, began on 31 July 2023.
  • Deployment of this asset is part of a pipeline of new projects that will take Gore Street Energy Storage Fund’s operational energy storage portfolio to in excess of 370MW.

Gore Street Energy Storage Fund (GSF), London’s first internationally diversified fund dedicated to facilitating the energy transition through deployment of energy storage, has selected EDF, Britain’s biggest generator of zero carbon electricity, as its trading and optimisation partner for a new 80MW battery energy storage system (BESS).

The agreement will see EDF optimise the Stony BESS through its market-leading Powershift platform, providing access to a variety of revenue streams including the Balancing Mechanism, wholesale optimisation and ancillary services, alongside leveraging EDF’s trading expertise.

This is the third contract GSF has awarded EDF, which already manages the trading and optimisation for both the 20MW Lascar and 20MW Hulley BESS assets.

EDF is a leading provider of route-to-market services for storage developers and investors and is committed to the long-term future of energy storage systems, with more than 950MW of battery optimisation contracts signed.

With existing installed capacity close to 110MW online in GB as part of a 292MW operational portfolio across four international energy markets, GSF is recognised as one of the leading battery operators.

Stuart Fenner, Director of Wholesale Market Service Commercial, at EDF said: “We are very pleased that Gore Street Energy Storage Fund has once again chosen EDF as its trading and optimisation partner and we are committed to continuing to strengthen our relationship into the future. This partnership will provide essential flexibility to the energy system and reinforces EDF’s commitment to helping Britain achieve net zero.”

Alicja Kowalewska-Montfort, Technical Principal at Gore Street Capital, the investment manager of Gore Street Energy Storage Fund, said: “EDF has a strong track record with two of our existing assets, making the agreement to take on Stony a natural progression based on consistently good performance. Its commercial offer represented best value for Gore Street Energy Storage Fund, and we look forward to building on our joint success with the fund’s biggest GB asset to date.”
