John Laing Environmental Assets Group has acquired the CSGH solar portfolio for a total consideration, including working capital, of £12.2m.
JLEN said the portfolio comprised four ground mounted solar parks with a total generating capacity of 33.5MW.
It said Higher Tregarne, located in Cornwall, had been operational since March 2014, had a generation capacity of 5 MW and was accredited for 1.6 ROCs.
It said the other three solar parks, Crug Mawr, Golden Hill and Shoals Hook, were located in South Wales, had been operational since March 2015, had a total generation capacity of 28.5MW and were accredited for 1.4 ROCs.
JLEN said it purchased the entire share capital of the holding company of the CSGH solar portfolio from sPower Holdings (UK) Limited.
It said the acquisition was funded by a draw-down under the company's revolving credit facility and brought the total capacity of the renewable energy assets in the JLEN portfolio to 225.2 MW.
