Farnham Project Energisation

Harmony Energy Income Trust plc, which invests in battery energy storage systems ("BESS") in Great Britain, is pleased to announce that its 20 MW / 40 MWh Farnham project (located in Surrey) has been successfully energised and is expected to be fully operational by the end of June 2023. The Farnham project is the Company's third project to be energised and takes the total operational capacity within the Company's portfolio to 129 MW / 258 MWh.

The project was developed by Harmony Energy Limited (the "Developer") and construction of the project was managed by Tesla with oversight from the Harmony Energy Project Team. Farnham will be operated through Autobidder, Tesla's algorithmic trading platform, which has also been deployed at the Company's Pillswood and Broadditch projects.

The Company's five projects under construction continue on track, in line with their timelines, with the Developer's own project management teams on site, overseeing progress.

Peter Kavanagh, Director of Harmony Energy Advisors Limited said:

"The roll out of our BESS projects continues at pace, as outlined at IPO. We are focussed on playing an integral role in the UK's transition to renewable energy alongside delivering attractive and sustainable returns to shareholders.

"Farnham is our third project to be energised, taking our total operational capacity to 129 MW. Looking ahead, we remain on track to increase the operational capacity of the Company's portfolio to over 300 MW by year end."
