GridAmerica to cease operations

National Grid USA and GridAmerica participants, FirstEnergy and Northern Indiana Public Service Company, today jointly announce that all three companies have agreed to cease GridAmerica operations effective 1 November 2005 utilising a similar contractual provision that the other GridAmerica participant, Ameren, exercised earlier this month.

GridAmerica, a subsidiary of National Grid Transco (NGT), is an independent transmission company operating within the footprint of the Midwest Independent Transmission System Operator, or Midwest ISO.

NGT is pleased with the performance of GridAmerica over the past 18 months and will be looking to reapply the skills and knowledge brought to its participation in GridAmerica as it seeks to develop interests in North America.

These statements are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Because these forward-looking statements are subject to assumptions, risks and uncertainties, actual future results may differ materially from those expressed in or implied by such statements. Many of these assumptions, risks and uncertainties relate to factors that are beyond National Grid Transco's ability to control or estimate precisely, such as delays in obtaining or adverse conditions contained in regulatory approvals, competition and industry restructuring, changes in economic conditions, currency fluctuations, changes in interest and tax rates, changes in energy market prices, changes in historical weather patterns, changes in laws, regulations or regulatory policies, developments in legal or public policy doctrines, the impact of changes to accounting standards, technological developments, the failure to retain key management, the availability of new acquisition opportunities or the timing and success of future acquisition opportunities. Other factors that could cause actual results to differ materially from those described in this announcement include the ability to continue to integrate the US and UK businesses acquired by or merged with the Group, the failure for any reason to achieve reductions in costs or to achieve operational efficiencies, unseasonable weather impacting on demand for electricity and gas, the behaviour of UK electricity market participants on system balancing, the timing of amendments in prices to shippers in the UK gas market, the performance of National Grid Transco's pension schemes and the regulatory treatment of pension costs, the impact of the proposed disposal by National Grid Transco of 4 of its UK gas distribution network and any adverse consequences arising from outages on or otherwise affecting energy networks owned and/or operated by National Grid Transco.

For a more detailed description of these assumptions, risks and uncertainties, together with any other risk factors, please see National Grid Transco's filings with the United States Securities and Exchange Commission (and in particular the "Risk Factors" and "Operating and Financial Review" sections filed with its most recent annual report on Form 20F).
