Dong Energy is to supply renewable power to Welsh Water’s sites across Wales and Herefordshire.
Welsh Water already generates 20% of its own energy needs through wind, hydro, solar and anaerobic digestion and aims to increase this to 30% by 2019.
The announcement follows an agreement for a £250m loan facility with the European Investment Bank.
The loan will help finance Welsh Water’s capital expenditure programme and future renewable energy generation plans.
Welsh Water managing director of wastewater services Steve Wilson said: “We are delighted to begin our contract with Dong as it secures green energy for the next five years while offering good value for our customers.
“We’ve significantly increased the amount of energy we generate at our sites over the past few years by embracing technologies such as solar panels, hydro turbines, anaerobic digestion and our first wind generation sites in the past 12 months.
“By incorporating these sources with the green energy we now receive from Dong, we really are able to make a meaningful contribution to protecting our environment from the effects of climate change.”
