PSE&G’s Solar Initiative Plan filed with BPU on  4/19/07…

PSE&G would invest $100M over 2008-2009 to help finance installation
of 30MW of solar photovoltaic systems on homes, businesses and
municipal buildings.

The solar initiative is designed to fulfill 50% of the renewable portfolio
standard (RPS) requirements over a two year period.

Program will provide loans to developers to cover 40-50% of the cost of
solar installation project. The remaining cost of the project will be
funded by an equity partner (or host customer) who would also own the
solar panels.

PSE&G will be repaid the principal plus interest over 15 year period in
the form of credits called Solar Renewable Energy Certificates (SRECs)
or, in cash.  PSE&G will allocate SRECs to Load Serving Entities (LSE)
which will lower their renewable portfolio compliance cost standards
over time.

PSE&G would earn a return for the full cost of capital plus an incentive
for spurring the solar market.

… first step to meeting Energy Master Plan requirements.

PJM released results on April 13 from its

first capacity auction under the Reliability

Pricing Model (RPM) for the 2007-2008

delivery year.

Pricing in initial auction for Eastern MAAC

reflected “Cost of New Entry”: standard

simple cycle gas turbine adjusted for

location.

Future auction pricing could be influenced

by changes in demand and capacity

availability including transmission capability

between zones.

Market prices support our forecast year-

over-year improvement in capacity margin

of $125M - $175M in 2007 with further

improvement in 2008.

Auctions are scheduled throughout the

year to provide transition through the 2010-

2011 delivery year.

Looking ahead, Power is well positioned to benefit from
generation value improvement …

Tightening reserve margins should:

Put upward pressure on capacity prices, and

Drive heat rate expansion if baseload additions are insufficient

The implementation of carbon rules is becoming more likely

Anticipated to put upward pressure on prices

Nuclear generation stands to benefit from carbon constraints
