Joint Press Release by Arenko Group ("Arenko") and Gresham House Energy Storage Fund plc ("GRID")

Gresham House Energy Storage Fund PLC agrees to award a further 455MW of Optimisation Agreements to Arenko

Arenko, a leading software platform provider to the global energy market, and Gresham House Energy Storage Fund (LSE: GRID), the UK's leading energy storage fund are pleased to announce that they have expanded their partnership. The continuation and expansion of this multi-year relationship is evidence of the parties' strong working relationship and their shared commitment to decarbonisation and innovation in the energy sector.

Highlights:

- Arenko has been awarded contracts to carry out asset optimisation on an additional five utility scale batteries for GRID. The contracts, totalling 210MW, are expected to come into force during 2022

- GRID has also renewed the Byers Brae 30MW battery contract which Arenko has been optimising since March 2021

- An additional framework agreement to optimise a further 215MW has also been agreed

- When combined with previous announcements, Arenko will have been awarded contracts for the asset optimisation of over 500MW of GRID's market-leading energy storage portfolio

These asset optimisation agreements (known as Automation and Digitalisation Agreements) substantially build on the relationship between Arenko and GRID, having started working together in 2020 following the Fund's acquisition of the 41MW Bloxwich energy storage project, which Arenko continues to optimise today.

Under these agreements, Arenko will use its proprietary end-to-end trade optimisation and automated dispatch software to maximise returns from these assets.

Ben Guest, Fund Manager, Gresham House Energy Storage Fund PLC, said:

"We are very pleased to have reached this agreement with Arenko. Arenko are among the leading asset optimisation services providers in the UK, and, increasingly, internationally.

Gresham House Energy Storage Fund is committed to achieving excellence in all areas of its business, including the maximisation of its potential revenues and this overall agreement is an important part of this effort."

Rupert Newland, Founder and CEO of Arenko Group, said:

"Arenko is proud to count Gresham House Energy Storage Fund, which owns and operates the largest portfolio of energy storage in the UK, among its clients which include multiple listed energy firms and specialist energy storage funds. This framework agreement exemplifies Arenko's strong desire to build lasting relationships with top tier investors and businesses.
