National Grid Appoints US Board Director

The Board of National Grid plc is pleased to announce the appointment of Tom King as an Executive Director with effect from 13 August 2007. Tom will be based in the US and will have responsibility for the electricity distribution and generation businesses.

Tom has more than 20 years of experience in the US energy industry. Most recently he was CEO of Pacific Gas and Electric Company, which is one of the largest investor-owned gas and electric utilities in the US, serving northern and central California. Tom was part of the leadership that, after its re-emergence from bankruptcy, established PG&E on its journey to a top performing utility, improving operational performance and significantly improving customer service and its credibility with the regulator.

National Grid Chairman, Sir John Parker, commented:

“We are pleased to welcome Tom to the National Grid Board. He brings a wealth of operational expertise and experience from the US electricity and gas industry.”

Steve Holliday, National Grid Chief Executive, added:

“I am delighted that Tom will be joining us; he has the ideal background in both electricity and gas industries. He also has a great track record of implementing change, to drive improvements in reliability and customer service. His appointment is an important final step in building the management team at National Grid to drive the business to a new level as we near the completion of KeySpan.”
