| National Grid Launches New Brand Campaign - 'The 
    Power of Action'   WALTHAM, Mass., May 05, 2008 -- BUSINESS WIRE
 It's the beginning of a new era, as National Grid launches a new brand 
    campaign featuring the tagline, 'The power of action.' The campaign is 
    designed to encourage customers to partner with National Grid and take 
    action in making a difference by saving energy, managing their energy costs 
    and protecting the environment.
 
 National Grid has rebranded the former KeySpan operations in the company's 
    service areas in New York (metropolitan area and Long Island), New Hampshire 
    and Massachusetts. Customers will notice the National Grid logo on bills, 
    employee ID cards, company vehicles, office locations and elsewhere. The 
    company expects the full conversion will be completed by the end of the 
    year.
 
 "This initiative comes at a great time for National Grid as we start a 
    journey with our employees and the community on ways to address climate 
    change and manage energy costs," said Tom King, president of National Grid's 
    U.S. business. "We have worked with our customers for 20 years on energy 
    efficiency measures and saved over $2.5 billion and 26 billion 
    kilowatt-hours. But we want to do more. By using our new 'The power of 
    action.' message across the company and in local communities we can show 
    that if one person can accomplish a lot by the simple things they do each 
    day, imagine what we can do collectively."
 
 'The power of action.' brand campaign complements National Grid's recent 
    announcement of an 80 percent target reduction in greenhouse gas emissions 
    by 2050. Under this new initiative National Grid will adopt "carbon budgets" 
    that will limit the greenhouse emissions permitted by each part of the 
    business. Beginning in April 2009, annual and five-year emissions targets 
    will be established for each business and integrated into the company's 
    performance process alongside customer service, reliability, safety, 
    operational and financial targets. National Grid employees will be 
    responsible for reducing the company's carbon footprint by identifying the 
    most efficient and effective ways of carrying out its electricity and gas 
    operations.
 
 The brand strategy includes an advertising campaign beginning today in all 
    major markets in which the company does business. The advertisements focus 
    on smart energy choices that we all can make from conserving power to 
    converting to natural gas to weather-proofing our homes - taking action.
 
 "This is just the beginning, customers will continue to see and hear more 
    from us as we partner with them on this journey. National Grid is determined 
    to help customers recognize that their actions, along with ours, have a 
    powerful benefit," added King.

    National Grid delivers electricity to approximately 3.3 million customers in
