Energy regulator Ofgem published the news as part of its annual report earlier this month.

Electricity North West, which operates the overhead lines and underground cables throughout the region, was ranked top among the six companies that own the country’s 14 local power networks.

Each year Ofgem rates the networks to show areas of good and poor performance. The six key metrics are: Reliability and availability, connections, social obligations, customer service, environment and safety.

Peter Emery, chief executive at Electricity North West, said: “As a company, our performance against a wide range of metrics meets or exceeds Ofgem’s expectations, I’m delighted that this has been recognised by Ofgem.”

“To be given green across the board for the third year running, outperforming all other groups that own Great Britain’s power networks is something to be proud of.”

“Right across the business, our teams are striving to improve our performance and provide the best possible service to our customers in the North West. We’re part of an industry that is changing rapidly and look forward to helping the Region transition to zero carbon.”

Electricity North West has also reported its highest ever levels of customer satisfaction, exceeding the industry-wide target of 82%, scoring 86.5% satisfaction.

Previously, Ofgem stated Electricity North West had “exceeded all reliability targets... as well as the targets for average time to quote and time to connect”.
