     IT'S OFFICIAL -- NEES/NATIONAL GRID MERGER IS COMPLETE
     ------------------------------------------------------
                 NEES Renamed National Grid USA

     WESTBOROUGH, Mass., March 20, 2000   The merger between The
National Grid Group plc (National Grid) and New England Electric
System (NEES) is complete, and NEES officially has been renamed
National Grid USA, according to Rick Sergel, president and chief
executive officer of National Grid USA.

     Sergel and National Grid Group Chief Executive David Jones
signed documents to close the deal, which was announced on
December 14, 1998.  The final sale price for the merger was $3.2
billion, and the final price of NEES shares was $54.207.

     "We agreed to merge our companies with the belief that our
customers, our employees and the region as a whole will benefit
from our combined strengths," Sergel said.  "Now that we have
closed on this historic merger, we intend to work on delivering
those benefits."

     Although the NEES name has changed, the names of its local
electric companies   Massachusetts Electric Company, Granite
State Electric Company (NH), Narragansett Electric Company (RI),
and Nantucket Electric Company   will remain the same.


     "Preserving the names of our local electric companies
reflects our commitment to continuity for our customers and
communities," said Sergel.

     Company officials today unveiled National Grid USA's new
logo and corporate identity, and launched three new Internet
sites containing detailed information about National Grid's U.S.,
U.K., and worldwide operations:

base of North American operations for National Grid Group. Sergel
and NEES director Paul Joskow, professor of economics and
management at the Massachusetts Institute of Technology, will

the necessary state and federal regulatory agencies, and the

expected to close in the near future.
