Commenting on the Fund’s results, John Leggate CBE, Chair of Gresham House Energy Storage Fund plc said:

“2020 was a milestone year for GRID, with the need for battery storage highlighted by the sharp mismatch in power supply and demand during the first UK lockdown, and the Government accelerating decarbonisation targets.

“We have a substantial project pipeline and access to the necessary resources to deliver on our ambitious plans to maintain the growth momentum of our battery storage portfolio. This is fundamental to delivering a stable, cost effective, and carbon-free power generation infrastructure.”

Ben Guest, Fund Manager of Gresham House Energy Storage Fund plc & Managing Director of Gresham House New Energy said:

“The UK’s global leadership in renewable generation and in its setting of ambitious decarbonisation targets, continues to make it one of the world’s most attractive markets for deployment of utility-scale battery storage technology. We are encouraged by the system operator, National Grid, continuing to test and facilitate new ways for battery storage to contribute to system balancing.

“More renewable energy on the system will inevitably lead to more intraday power price volatility, driving the improved revenues and profit from trading which GRID is best positioned to capture. We are intent on driving shareholder value by maximising project returns through our portfolio scale as well as operational and cost leadership, while striving to reduce our cost of capital, including through a potential new debt facility.”

An online webinar and Q&A session, to discuss the results and provide an update on performance in Q1 2021, will be held at 9am today, Wednesday 28 April 2021. This will be an opportunity to hear GRID’s fund manager, Ben Guest, provide an update on the Fund’s operational and financial performance and to ask questions.
