Energy Efficiency, Demand Response and
Renewables: Opportunities for Growth

Climate Change

The science on Climate Change is real and not debatable.

Satisfying the world’s appetite for energy contributes to the growing crisis
of global climate change.

NJ can help lead the way in reducing the threat of climate change, and
position NJ to be as economically competitive as possible as the world
mobilizes to address that threat.

PSE&G is committed to apply its broad-based expertise and “patient”
capital in new ways to reduce energy demand, spur investment in
renewable resources and develop new sources of carbon-free supply.

PSE&G will continue to do its part as a leader in the energy industry and
responsible corporate citizen, working closely with other stakeholders to
tackle the most important environmental challenge of our time.

Energy Master Plan (EMP)

• Draft EMP released by Governor’s Office on April 17, 2008.

• Under a “business as usual” approach with no changes in State

policies or actions, New Jersey’s projected energy demand in 2020

will be about 100,000 GWh of electricity and over 590 trillion BTUs of

natural gas.

• In addition, greenhouse gas emissions from the electricity and heating

fuel sectors will increase to over 90 million metric tons of carbon

dioxide.

GOAL 4:

Develop new low carbon emitting, efficient power plants and close the gap between the supply and demand of electricity.

GOAL 5:

Invest in innovative clean energy technologies and businesses to stimulate the industry’s growth in New Jersey.

PSE&G’s Role

“Green” initiatives include:

Campaigning for tougher power plant emission standards

Installing new electrical wires and state-of-the-art transformers
that are expected to reduce carbon emissions by almost 60,000
tons by year 2020

CFL Pledge Campaign

Replacing 1,300 corporate fleet vehicles with fuel-efficient hybrids

Advanced Metering Infrastructure BPU Filing

Carbon Abatement Pilot BPU Filing

Helping customers obtain the latest energy-saving technology, such as
programmable thermostats and high-efficiency lighting

EMP Working Group leadership and participation

Utility consensus position on utility participation in efficiency

RGGI legislation

PSE&G’s Blueprint for Sustainability – a challenge and an
opportunity

New Jersey has passed legislation that recognizes the
important role of utilities in promoting a sustainable energy
future.

In April, PSE&G received approval from the NJ BPU to
begin a $105 million investment in solar energy.

We are working hard to obtain approval of two other
initiatives:

Carbon abatement pilot

AMI pilot to deploy and test advanced metering infrastructure

Why did PSE&G initiate the Solar Loan Program?

At PSE&G, we’re committed to doing our part to save energy, slow global
warming, and reduce our dependence on foreign oil. As New Jersey’s largest
utility, PSE&G is uniquely positioned to provide the capital resources needed to
implement this program.

Overview – Innovative Program

In April, PSE&G received BPU approval of a 2-energy year program to
provide for the financing of solar panels and related equipment (Solar
Energy System) to properly qualified borrowers on a first come, first
served basis.

The Solar Energy System must be installed within PSE&G’s electric
distribution area and be eligible for net metering.

Each loan will be secured by a first priority lien on the solar
equipment, Solar Renewable Energy Certificates (SRECs) and project
documents collectively, the “Collateral”.

The borrower can repay the loan either in cash or by delivering
SRECs generated by the Solar Energy System to PSE&G as payment.

PSE&G estimates that the financing will represent approximately 40%
to 60% of total capital cost to purchase and install a Solar Energy
System.

The actual loan amount is based on the Solar Energy System
production capabilities (anticipated energy (mwh)).

PSE&G is exploring additional investments

* Plans not finalized and assumes that all regulatory approvals are obtained in the timeframe needed.

PV Solar:

PSE&G supplies 50% of the RPS requirements

Declining costs would increase % of RPS supplied with

same dollar today.

Energy

Efficiency:

50% of EMP goal (excluding portion met by code changes) in PSE&G service territory.

Demand

Response:

Retool current AC Cycling program to replace existing

equipment.

Onshore

Wind:

5MW on-shore wind; utility-owned

CHP:

Focus on the hospital segment to capture a % of the

total EMP load of 1500MW.

Other:

Consideration for emerging opportunities such as, green

collar jobs, geothermal, “Green Street Lights” and PHEV

Why PSE&G?

Throughout its 104-year history PSE&G has been committed to

providing safe, highly reliable energy as cost-effectively as possible.

PSE&G is part of the community it serves and its customers are its

neighbors. This close relationship puts the utility in a unique position

This innovative loan program also provides opportunities for tax equity players to
invest in solar installations on PSE&G customer facilities.

Program is now available to non-residential segment.

Residential segment should be ready in 2 - 4 months upon approval of Dept. of
Banking and Insurance and BPU stakeholder process.

Rates and Return

PSE&G will provide loans to four different market segments, with specific loan
characteristics:

11.11%

6.5%

Interest Rate

15 years

10 years

Term of Loan

Municipal

I&C

Multi-Family/

PSE&G’s pre-tax WACC is 11.11%. In the Residential segment, the interest rate
of 6.5% is supplemented with a charge to all ratepayers to provide PSE&G its
WACC on the loan.

The settlement also defines a guaranteed PSE&G ROE of 9.75% with recoverable
administrative costs not to exceed $1MM in any year and no lost revenue.

If loans are paid off early, PSE&G retains the right to purchase SRECs through a
call option.  The call option price is 75% of the then current Market Value of
SRECs.  The parties agreed that the call option provides benefits to ratepayers
after the loan has been repaid.  The price will be determined at the time the
Company seeks to exercise the call option.

Key Loan Terms and Conditions

The borrower will fully repay the loans by providing PSE&G with

SRECs or cash, to repay principal and interest.

For every megawatt hour of energy produced by the Solar

Energy System, NJ’s Office of Clean Energy will credit the

borrower’s SREC account with one SREC (1mwh = 1 SREC).

Periodically, the SRECs will be transferred to PSE&G’s SREC

account as payment of the loan.

For repayment purposes, PSE&G will value the SRECs at the

greater of: the floor price of $475 per SREC, or the actual market

value at the time the SREC is credited.

Loan repayments are scheduled as fixed monthly payments

containing interest and principal.

Key Loan Terms and Conditions

PSE&G will conduct an annual true-up to compare the amount
due under the loan agreement with the sum of the value of all
SRECs generated that year.

The borrower will be required to pay any resulting shortfall (in
cash) to PSE&G. The owner of the Solar Energy System bears
the production risk.

If the value of the SRECs exceeds the amount due under the
loan agreement, such surplus will be credited toward the
outstanding balance to accelerate the amortization of the loan.

Each borrower will have a minimum credit score, no bankruptcy
in the preceding 3 years and a favorable PSE&G credit
assessment.

Cost Recovery

PSE&G will recover the net monthly revenue requirements associated
with the Program through a new Solar Pilot Recovery Charge (“SPRC”),
which will be applicable to all electric Rate Schedules.

PSE&G will defer costs to the SPRC for future recovery.

When SREC > $475, Ratepayer will realize a
benefit to the extent the loan is prepaid and the
call option for the SRECs are exercised. When
SREC < $475, Ratepayer will experience a
shortfall. When SREC = $475, Ratepayer is

neutral with regard to the non-residential

loans. The ratepayer is always out of

pocket with respect to the admin cost and to
cover the difference between WACC and the
6.5% coupon rate on the residential loans.

Ratepayer funds

The current SREC life is 1 year. A proposed change to the SREC life would change the SREC life to
2 energy year plus 3 months.
