Whirlwind Update

The Company and Ecofin have been saddened to hear of the loss of life in Matador, Texas following the recent tornado and convey their deepest sympathies and condolences to all those affected by this tragic event.

On 21 June 2023, the Company's 59.8 MW Whirlwind Energy wind farm ("Whirlwind") in Floydada, Texas, temporarily ceased operations due to the tornado, which damaged five project-owned transmission poles. There were no casualties or injuries at Whirlwind. The Company has subsequently been informed that the American Electric Power owned substation in neighbouring Matador, through which Whirlwind transmits electricity, was severely damaged during the incident. As a result, Whirlwind will be unable to resume operations until the Matador substation is rebuilt. Due to the outage, the Company has declared a force majeure event with Whirlwind's offtaker, Austin Energy.

Ecofin is working closely with Whirlwind's asset and operations managers to put in place a plan and an expected timetable to remedy the outage at Whirlwind. The Company is also working with its insurance provider to file claims, where applicable, for business interruption and necessary repairs to the damaged project-owned transmission poles. Whether or not the Company is able to recoup potential losses resulting from the tornado under its insurance policies or other contractual arrangements, the Company expects the outage to have a material short term impact on cash flows. As at 31 March 2023, Whirlwind represented 38 per cent. of the net asset value (unaudited) of the Company, or 24.5 per cent. of gross asset value (including group debt)(unaudited).

The Company and Ecofin will continue to work closely with all relevant stakeholders and further announcements will be made as appropriate.
