Acquisition Update

Atrato Onsite Energy plc (LSE: ROOF), the renewables investment trust focusing on UK commercial onsite energy, today announces that it has acquired 100% of the shares of Hylton Plantation Solar Farm Limited ("Hylton"), a company set up to develop a 20MWp solar PV system for Nissan Motor Manufacturing UK Limited ("Nissan").

The £10.6m transaction sees the Company take on the ownership of a behind-the-meter private wire solar installation project for Nissan in Sunderland. The Company will complete the installation of a 20MW ground mounted system, using c. 37,000 panels, next to Nissan's manufacturing facility. Nissan has entered into a 20 year Power Purchase Agreement (PPA) on a 100% take-or-pay basis.

The project is expected to deliver highly visible, contracted cashflows with fixed uplifts, in line with the Company's targeted return.

Gurpreet Gujral, Managing Director of Atrato Partners, the investment adviser to the Company, said:

"I'm very pleased to announce this transaction, which brings a great installation project into ROOF's portfolio.

We are working closely with the UK automotive industry to deliver further green energy initiatives and to help them on their path to net zero.

This is one of the largest private wire solar projects in the UK and is a great example of how major UK manufacturers can benefit from ROOF's low cost, traceable clean energy."
