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.

… is the first step to meeting Energy Master Plan requirements.

PSE&G has identified major transmission paths …

New Freedom to Deans

An 80-mile line from Camden Co. (New
Freedom) north to Middlesex Co.
(Deans)

Will run parallel to existing transmission
where feasible

Branchburg to Roseland

A 30-mile line from Somerset Co.
(Branchburg) to Essex Co. (Roseland)

A reinforcement that would use the
same right of way as an existing circuit
that carries lower voltage

Susquehanna to Roseland

A 135-mile line from Luzerne Co., PA
(Susquehanna station) to Essex Co., NJ
(Roseland)

This project would include construction
of a new switching station on utility
owned property in Morris County

PSE&G endorsed construction of several new 500-kilovolt transmission lines

Construction would take place over 5-8 years
beginning in 2008

Costs would be shared throughout PJM – including

PJM released results on April 13 from its

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.

… as market fundamentals and regulatory policy impact market
conditions.

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

In addition to supply and demand fundamentals, electricity markets
will be affected by policies aimed at lowering CO₂ emissions.

PSEG’s generation carbon intensity is lower than many competitors and benefits from a
cap and trade program comparably applied to all competitors.
