          NSTAR Reports Second Quarter Results for 2003

Boston, MA -- NSTAR (NYSE: NST) today reported earnings available
for common shareholders of $39.2 million, or $0.74 and $0.73 per
basic and diluted common share, respectively, for the second
quarter of 2003, compared to $5.2 million, or $0.10 per basic and
diluted share for the same period in 2002.  Results for 2002
included a non-cash after-tax charge of $27.6 million, or $0.52
per share, related to the impairment of NSTAR's investment in RCN
Corporation.

The earnings improvement for the quarter reflects an increase in
electric revenue and a decline in operations and maintenance
costs that was partially offset by an increase in costs for
pension and other postretirement benefits.

Chairman, President and Chief Executive Thomas J. May said,
"Coming off a very positive year regarding our service quality
measures, we are on track during the first half of 2003 to attain
similar results."  May added, we completed significant upgrades
to several substations in our electric distribution system.
These upgrades, along with other improvements that we continue to
make, will help to ensure that our system will be able to handle
whatever the summer brings.

For the three months ended June 30, 2003, sales of electricity
and gas increased 2.5% and 18.7%, respectively, as compared to
the same period in 2002.

Management maintains its previous guidance for earnings for the
year 2003 at a range of $3.35 - $3.45 per basic share.
