The current business environment …

Convergence of market forces and policy
creates the need to address:

Critical infrastructure requirements

Environmental requirements

Capacity requirements in constrained markets

… creates opportunities for PSEG’s long-term growth.

Carbon Reduction – A common focus …

International directives

- More support globally since adoption of Kyoto Agreement in
1997 for reduction in greenhouse gas

On the national level

Multiple carbon legislative proposals are currently under
consideration by Congress

Legislation probable by 2008

Regional Greenhouse Gas Initiative (RGGI)

A nine state collaborative calling for a 10% reduction in
carbon from 2000 – 2004 levels by 2019

In New Jersey, Governor Corzine has signed
Executive Order No. 54 and the Legislature has
introduced multi-sector carbon legislation with
aggressive reduction targets.

… an issue we support and an opportunity for investment

NJ Energy Master Plan …

Identifies the same issues as those at the international and
national levels

Provides PSEG the opportunity to:

Meet environmental goals that we have long supported

Expand PSE&G through broader investment opportunities

Support growth in the State’s urban areas through investment in the
“Smart Growth Initiative” program

Expand Power through carbon-free generation

Shape the debate, find the solution and implement the plan

PSEG has pledged its full support to the effort launched by
Governor Corzine

PSEG expects to implement several proposals during 2007 to
support the Energy Master Plan, consistent with PSEG’s
business interests

… an Intersection of Energy – the Environment – PSEG

PSE&G – A consistent, strong performer …

Continued top quartile/top decile performance

National ReliabilityOne Award winner – two years running

American Customer Satisfaction Index (ACSI) Customer
Satisfaction Survey

Regulatory agreements provide opportunity to earn
reasonable returns over 2007-2009

Energy Master Plan initiatives fuel long-term growth

New customer information system investment (2007 - 2009)

Advanced Metering technology investment (2008 - 2012)

Renewables and energy efficiency enhanced by utility
participation (2008 – 2020)

… providing stability and multiple platforms for growth.

PSEG Power – Solidly positioned …

Nuclear and fossil fleet operating at historically high
levels with opportunity for improvement

Near-term growth fueled by strong markets and roll-off
of below market contracts

Long-term growth influenced by

Tightening reserve margins

Expansion capability at existing sites

Carbon advantaged portfolio

Debate on energy policy will influence investment

Environmental compliance driving current investment

Meeting EMP objectives may require a look at new nuclear
investment

… to provide strong growth for PSEG.

PSEG Energy Holdings - Improving returns and reducing
risk …

Diverse asset base with improved stability

Stable Latin American distribution assets in stable economies

Gas-fired combined cycle generation in Texas

A source of capital

Asset sales have reduced risk and contributed to an improved
balance sheet at PSEG

A source of growth

Texas generating assets benefit from location, low cost
structure and opportunity for expansion

… to create opportunities to redeploy capital.

Right set of assets…

Large, diverse mix of low-cost, base-load, load-following generating assets

Reliable electric and gas distribution and transmission systems

Stable portfolio of investments in domestic generation, international distribution and leases

Right markets…

Generation assets operate in tightly constrained and growing markets

Nuclear and coal base-load capacity operate in markets where the price for power is set by
gas

Transmission and distribution assets provide service in a modest growth market with
reasonable regulation

At the right time…

Mid-Atlantic, New England and Texas recognizing the value of capacity in constrained areas

A move to control carbon benefits our nuclear-based fleet

Power has opportunity for brownfield development at existing sites

Values are improving for international assets

T&D set to benefit from implementing state’s energy plan

PSEG – Excellent position for today …

… ready for tomorrow

… matches well with the PSE&G service territory and will create
long term growth within New Jersey’s urban centers.

The Governor’s plan to revitalize New Jersey’s urban centers has worked
as planned, resulting in PSE&G needing to invest to support its electrical
systems.

The New Jersey Energy Master Plan’s challenges for
PSE&G include …

PSEG Key Strategies with the Potential for Helping the State:

Advanced Metering Infrastructure

Solar Green Towns

Residential Energy Efficiency

Commercial and Industrial Energy Efficiency

Other options: Hybrid vehicles, company facility investments,
distributed generation

In support of Governor Corzine’s initiative, PSEG proposed strategies for
helping New Jersey achieve what are truly aggressive targets, and present
opportunities for future growth.

… competing proposals and receiving proper regulatory treatment
(i.e., decoupling and proper regulatory incentives).

Advanced Metering Infrastructure …

Advanced Metering Infrastructure (AMI) Benefits

More detailed usage information
on customers

Ability to create tailored price
options to customers

Opportunities for new revenue
streams

Opportunities to meet energy
conservation targets

Opportunities to develop a
competitive market that benefits
all customers

Lower operational costs

Fewer customer billing
complaints

Real time identification of

… represents up to $600M of capital investment between 2008-2012.

Solar Initiative helps to reduce local government energy
expenses and benefits taxpayers/consumers statewide …

NJ RPS requires ~2% of
energy supplied in 2020 to
originate from Solar Sources

~ 1,400 – 1,500MW at 14%

Green Towns Proposal:

PSE&G installations of
Photovoltaic panels on
municipal and school
buildings

Benefits:

Emissions-free power

Lower municipality / school

Global’s near-term strategy is to improve returns and
further reduce risk …

International – reducing generation risk

Proactively exploring potential sale of Electroandes ($160M Book Value)

Significant amount of interest expressed in non-strategic asset

Opportunity to reallocate capital if valuations attractive

Continue to assess opportunities regarding remaining modest international generation
investments (Turboven, PPN and Prisma - aggregate $150M investment)

Economically relever distribution companies in Chile & Peru – returning capital and
improving returns ($150M - $250M)

Incremental capital available

Optimize operations in distribution companies to improve returns and increase values

Will consider further monetizations as appropriate based upon valuations and alternate
use of capital

Ability to further leverage Texas assets could also generate incremental capital

… by continuing to return capital through opportunistic monetizations
and debt financing.
