This presentation contains forward-looking statements, which
are statements of future expectations and not facts.  Actual
results or developments might differ materially from those
included in the forward-looking statements because of
factors such as competition and industry restructuring,
changes in economic conditions, changes in historical
weather patterns, changes in laws, regulations or regulatory
policies, developments in legal or public policy doctrines,
technological developments and other presently unknown or
unforeseen factors.  Other risk factors are detailed from
time to time in the company's SEC reports.

WHERE ARE THE OPPORTUNITIES AND RISKS

     OPPORTUNITIES                 RISKS

Interest rates remain low

Strong O&M control            Electric transmission
continues                     projects scaled back

Regulated businesses          Unfavorable Yankee
exceed allowed returns        Energy rate decision

Economic growth exceeds       Accretive unregulated
modest targets                investments are not found

Unregulated business
investments achieve superior
returns

Prices and demand are holding up in NEON niche

SMOOTHLY FOR CL&P CUSTOMERS

CL&P rates fell 5% on 1/1/00 when retail choice began

CL&P locked in four-year supply contracts in 1999 when
purchase power costs were low

     Suppliers are Select Energy (50%), NRG (40%) and Duke(10%)
     Supply costs fixed through 12/31/03

Generation charge overcollects supply costs and surplus used
to amortize stranded costs

Virtually no load has switched to competitive suppliers

CURRENT YANKEE RATE CASE HAS SEVERAL KEY ISSUES

Rate support for aggressive capital program sought

PSNH RESTRUCTURING DISPUTE IS OVER!!!

On October 1, 2000, 5% rate cut implemented

On April 25, 2001, $525 million securitization bonds sold

On May 1, 2001, additional 11% rate cut and retail choice
began

On May 22, 2001, restructuring law was modified

     Sale of 1,200 MW of fossil/hydro generation delayed
     until at least February 2004

     Seabrook auction now under way; closing expected
     in 2002 and NAEC is then dissolved

On June 18, 2001, U.S. Supreme Court refused to hear appeal
of NHPUC restructuring decision



                          SLIDE #44


PSNH's ABILITY TO RECOVER REMAINING STRANDED
COSTS IS ASSURED BY MULTIPLED FACTORS

PSNH units and Seabrook produce energy competitively

Seabrook proceeds will be used to amortize stranded costs

Energy prices for large commercial and industrial customers
move to market rates in less than two years

Remaining PSNH coal, hydro, oil, and gas units can more
than cover remaining residential and small commercial load

Low interest rates on securitization bonds (5.9% vs. 7.5%
budget) significantly reduce debt service costs

Most importantly, state statute allows full recovery of
purchased power deferrals beyond 2007, but we expect recovery to be
complete well beforehand


                          SLIDE #45


WMECO STORY HAS BEEN SIMPLIFIED

No bonds or preferred stock remain

No generation, except for small share of Vermont Yankee
being sold

Pass through of higher purchased power costs allowed

     17% rate hike took effect 1/1/01
     Standard Offer rate expected to drop to 4.8 cents/kwh on 1/1/02

Service reliability remains solid, but growth slow

All purchased power contracts renegotiated

     Securitization paid the costs

Earnings have been strong - - 14.4% ROE for 12 months ended
6/30/01

Distribution rates stable since January 2000

BOTTOM LINE AT REGULATED BUSINESS

Regulatory, Legislative relationships best in decades

System performance is good

Intense focus on productivity and cost efficiency

Investment in new Connecticut gas and electric projects
mitigates sale of plants, amortization of regulatory assets

Earnings growth slower at PSNH and WMECO

Earnings growth faster at CL&P and Yankee as capital
projects proceed, assuming timely regulatory orders

Cash generation should remain strong as amortization
continues

SUBSTANTIAL PERFORMANCE IMPROVEMENTS ACHIEVED
DURING PAST DECADE BY 103 U.S. NUCLEAR PLANTS

Average nuclear production costs have decreased 53% (1.74
cents/KWh in 2000 vs. 3.68 cents/KWh in 1990)
Average capacity factor has improved by 40% (89.6% in 2000
vs. 64% in 1990)

Average duration of refueling outages has decreased by 62%
(40 days in 2000 vs. 105 days in 1990)

Nuclear generation increased by the equivalent of adding 23
new 1,000 MW plants, despite 7 plants permanently retired
(183 million MWh since 1990)

Unusual events reported to NRC dropped 88% (from 151 in 1990
to just 18 in 2000)

     NRC currently reviewing 17 requests
     Most around 1.5%, some BWRs up to 20%
     Industry plans to increase capacity by 1,600 MW over
     next five years

License Renewal will enhance plant's economic value

     NRC has renewed Calvert Cliffs 1&2, Oconee 1,2,3, and
ANO-1 licenses for 20 yrs.

     Currently NRC reviewing applications covering 12
additional reactors

     Most other reactors are expected to extend their
