UK-based investment company Harmony Energy Income Trust plc (“HEIT”) has successfully energised (brought online) the 33 MW / 66 MWh Wormald Green and 49.9 MW / 99.8 MWh Hawthorn Pit Battery Energy Storage Systems (“BESS”).
Both projects, which can store enough energy to power the equivalent of an estimated 200,000 homes for two hours, utilise Envision Energy’s 2-hour duration liquid-cooled energy storage systems, capable of providing energy trading, capacity services, and frequency regulation services. These projects mark Envision Energy’s first operational batteries in Great Britain and the first in partnership with HEIT.
Developed by Harmony Energy Limited, the projects are the first BESS assets bp has contracted to optimise since its acquisition and integration of the digital energy platform Open Energi in 2021. The software developed by Open Energi will enable real-time insight and decision-making to connect HEIT’s assets with power markets through bp’s trading business.
The energisation of both BESS marks a step forward with efforts in Great Britain to contribute towards decarbonising the grid. It takes HEIT’s total operational capacity to 395.4 MW / 790.8 MWh across eight projects (100% of the portfolio).
Max Slade, Director of Harmony Energy Advisors Limited, said: “The energisation of Hawthorn Pit and Wormald Green represents another significant step in our mission to help power a sustainable future. To have completed construction of all eight projects in the portfolio since the IPO of HEIT plc in late 2021 is a remarkable achievement and is testament to the skills and dedication of our key suppliers, not least Envision Energy, as well as the strong project management and delivery capabilities of the team at Harmony Energy. Our portfolio is the second largest in Great Britain by MW, and the largest portfolio with exclusively 2-hour duration technology.
“It’s been a pleasure to work with Envision Energy on these two projects.”
Marking their first live batteries in Great Britain, Mark Walton-Hayfield, Senior Director of Envision Energy BESS, said: “We are thrilled to see our first energy storage systems in the UK come online, marking a significant milestone in Envision Energy’s global mission to accelerate the energy transition. This successful energisation, in partnership with HEIT, demonstrates the robustness and reliability of our energy storage systems. We are committed to supporting GB’s decarbonisation goals and are excited to continue collaborating with partners like HEIT who share our vision for a sustainable energy future.”
