Dong Energy A/S (CPH:DENERG) will supply green energy to Welsh Water's 4,300 sites under a five-year contract secured in a competitive tender, the Denmark-based energy company, whose renewable electricity comes from offshore wind, said on Wednesday.
Welsh Water, a not-for-profit utility, already generates on-site renewable energy and the contract with Dong will ensure its grid supplies are also green, making it a green-only energy user.
Jeff Whittingham, managing director of Dong's UK sales business said the contract represents significant growth of the company's power business which has continued to grow during the first half of 2017.
In a separate announcement last week Welsh Water said the contract is a major step forward for the company with an annual energy bill of over GBP 44 million (USD 56.7m/EUR 49.6m).
Welsh Water currently generates 20% of its energy demand through renewable sources, including wind, hydro, solar and anaerobic digestion and aims to lift that percentage to 30% by 2019.
Welsh Water also announced a GBP-250-million loan with the European Investment Bank (EIB) that will help finance its capital expenditure programme and its plans to boost renewable generation at its sites.
