JC-31 cl EXECUTIVE

SUMMARY

The GPU Conservation and Load Management Master Plan is designed to affect the unconstrained GPU system load g$owth in a way which minimizes the cost of service to our customers, minimizes future investments in gen-eration capacity, conserves energy, lessens dependence on foreign oil and optimizes the use of existing gener-I ating capacity.

GPU believes that an ambitious but realistic goal of reducing this unconstrained load growth by at least 1,000 megawatts in 1990 is necessary, desireable and attainable.

This reduction, as shown in Figure 1 will lower the forecast 1990 summer peak load Figure 1 impact of Master Plan Summer Peak Forecast GPU 9000 f_

s from about 8,000 megawatts (2.7 percent annual growth rate) to about 7,000 megawatts (1.5 percent annual growth rate).

The fundamental theme of the Master Plan is GPU's "capaci'ty offset" business strategy.

This strategy attempts t'o b'alance the future supply and demand for electricity through the most cost-effective investments available.

Thus, customer end-use equipment (e.g.

/

storage water heaters) may be viewed as appropriate alternatives to new generating capacity.

These alter-natives will be judged on the basis of GPU's marginal costs rather than embedded or average costs.

This methodology will ensure that GPU deploys its future capital investments in the most efficient manner possi-ble.

Moreover, from society's perspective, GPU provid-ing end-use items relieves the burden from the customer who might not make the correct economic decision to purchase load shifting equipment were he left to buy such. items on his own.

The Plan proposes that the capital required to pro-vide these end-use items should be treated in a manner i

analogous to capital commitments in new generation facilities, i.e.,

recognition in rate base.

This basic X

F

premise will be reviewed by both New Jersey and Pennsyl-vania rate regulatory agencies in the next few months.

By encompassing the supply of end-use items, the Plan

~

proposes a realistic treatment of capital by the utility and off' sets the need to convince customers to make investments in conservation.

GPU first established a load management policy in 1975 and since then hts instituted a broad. range of I

individual projects.

The GPU Co,mpanies have promoted time-of-day rates from as early as 1973, began energy audits in 1978, implemented off-peak control of water heaters, demonstrated more than thirty off-peak thermal storage systems, tested cooling storage installations, started Energy Management Committee programs with all of our large commercial and industrial customers, and have accomplished load shifts and savings of greater than 470 megawatts in the period.

The GPU Master Plan encompasses these existing pro-grams and, along with other new programs, provides an integrated approach to controlling future load growth.

The Plan also recognizes the special characteristics of GPU's customers ' loads and GPU's own particular cir-cumstances.

xi w..

1 w

a The Plan has two major segments; the Residential Program and the Commercial and Industrial Program.

Each is summarized below.

I.

RESIDENTIAL PROGRAM The Residential Program focuses on the supply by GPU of end-use equipment such as storage water heaters as well as the implementation of time-of-day (TOD) rates.

In addition, the program includes energy a.udits, storage

/

space heating, demonstration solar systems, and direct load controls.

Other facets of the program will receive consideration as development and verification of cost-effectiveness warrants.

All components will be con-sistent with the general Residential Program theme of shifting peak loads and offsetting peak capacity requirements.

In contrast to the commercial and industrial sectors, conservation opportunities for electricity in the GPU system residential sector appear to be relatively limited.

The various aspects of the Residential Program are outlined below:

l'.

Time of Day Rates:

Starting in'1981, all new construction customers with electric space heat, electric water heat or both will be required to receive service under the TOD xii 1

- - + -

• v7 Y

-e

. rate.

Turnover customers (new customers in existing housing) with monthly usage over 1,000 kilowatthours will also be required to go on'the TOD rate.

' Existing customers will r

not be required to accept TOD rates, however, th9y will be actively recruited.

2.

Energy Audits:

Those customers who must use the TOD rate will be provided a comprehensive f

energy audit. Additionally, the audit program will comply with each state's Residential Conservation Service (RCS) Program.

3.

Weatherization:

GPU will prc' ride advice and, if required, limited on-the-spot weatherization at the time of the energy audit.

GPU also proposes that " super" insdlation levels be mandatory for new home construction and will actively encourage the use of high efficiency air conditioners.

4.

Storace Water Heaters:

This program proposes that storage water heaters be provided to all required TOD rate users and to voluntary TOD users on request.

xiii

5.

Storage Space Heating:

This program proposes that thermal storage space heaters be supplied to all-required TOD rate users and will be

~

offered to existing electric space heating cus-tomers who voluntarily accept TOD rates.

6.

Demonstration Programs:

Demonstration programs will be conducted in the areas of solar technology, remote control of storage water

/

heaters and remote control of air conditioners.

II.

COMMERCIAL AND INDUSTRIAL PROGRAM The Commercial and Industrial Program is balanced between load shif ting and conservation activities.

Because detailed end-use information is generally not sufficient to determine the specifics of programs suit-able for~ wide-scale deployment, the commercial and in-dustrial efforts will include a number of demonstration activities to identify and verify opportunities.

These demonstration efforts will provide a sound basis for the implementation of full-scale programs.

GPU will evaluate conservation and load management opportunities using the capacity offset investment approach previously described.

The benefits of this implicit marginal cost approach to system planning is expected to yield xiv

substantial benefits in the commer i l ca and industrial sectors.

Among the currently attractive programs are:

candidate Heating / Cooling Storage Heat Recovery Systems Direct' Load Controls Improved Building Des'ign Energy Efficient Lighting Energy Efficient Motors Energy Management Systems As in the Residential Program Industrial Program will rely heavily,.the Commerci tion of TOD rates.

Initially, all transmission voltage customers and other customers with greater than 3 mega-t i

watts of demand will be required to accept TOD rates.

The second phase w'ill include smaller primary and secondary voltage customers with over 500 kilowatts of demand.

2.

Customer Energy / Load Management Program:

T!

• s program envisions comprehensive a,udit/informa-tion activities where formal assistance will be given to individual customers and ' seminars i

will be established for groups of customers with similar needs.

Demonstration programs l

will be continued or established in each of the candidate arcas.

Once a program is demonstrated as cost-effective, wide-scale implementstion will begin.

3.

Curtailable Rates:

GPU will propose a new curtailable rate structure with a variety of customer options to enhance flexibility.

4.

Cogeneration:

GPU will actively pursue a variety of cogeneration opportunities for industrial, commercial and government customers.

As part of the Plan, GPU-will develop a series Xvi r

's of modular cogeneration systems, providing de-sign, economic analysis and technical consulta-tion for potential congeneration custoners.

The table below summarizes the projected load reductions for all of the components in both sectors.

8 e

1980 Forecast, the 1990 winter peak demand had been estimated to reach 7,850 megawatts.

If the initiatives outlined in the Plan are implemented, a much lower winter

peak, i.e.,

6,520 megawatts, is anticipated.

The 1980 Forecast estimated annual growth in winter peak demand to be about 2.6 percent.

With the impact of the Master Plan, the rate of increase can be slowed to less than 1 percent per year (i.e., 0.7 percent).

Because of the large scale deployment of thermal storage devices over the next decade, as explained in the Plan, the winter peak is reduced significantly more than the summer peak.

Nevertheless, the energy saving and capacity offset programs will cut the 1990 summer peak demand by 990 megawatts.

In the 1980 Forecast, the summer peak woul'd have been 8,050 megawatts.

With the impact of the Plan, the 1990 summer peak can be scaled back to 7,060 megawatts.

Without the Master Plan, summer peak demand would grow at 2.9 percent annually.

Under the Plan, growth can be held to 1.5 percent per year.

Conservation and load management will change GPU from a winter-summer "leapfroging" system to an increas-ingly summer peak system.

This will have a beneficial xviii b

impact on reserve margin requirements, capacity planning, maintenance scheduling, and relationships with PJM.

The total present value saving from the Master Plan is projected to be about $2.08 billion.

This saving results from deferring or eliminating new generating capacity and from reduced energy costs.

The GPU program budget for the Master Plan is about $580 million over the next ten years.

Most of these expenditures (71 percent) occur in the resi-dential sector and reficct the fact that indivi:iual custcmers in this sector are less likely or abic to invest in conser-vation or load management equipment.

The difference between the cost of meeting new loads or avoiding them produces the real benefits for GPU's rate-payers.

Figure 2 shows that if load grows, the cost of Figure 2 Costs of New Capaci2y and Master Plan GPU 2000 e

building new base capacity to supply additional power is significantly higher than the cost of the Master Plan.

If the Master Plan is adopted, GPU's customers can be sheltered from some of the burden of rising electric rates.

As long as the cost of reducing load through conservation and load management is below the cost of new capacity, the Plan is in the customer's best interest.

The gap between the two lines in Figure 2 is the basis for GPU's strong support of its capacity offset business strategy.

More-over, the difference in costs is the measure of the attractiveness to ratepayers of energy conservation and load management investments.

GPU proposes a three phase approach to the imple-mentation of the Master Plan.

During Phase I, GPU will work closely with the Pennsylvania PUC and New Jersey BPU, as well as other State agencies, to develop the conceptual framework and to shape the practical approaches necessary to implement the Plan.

GPU will initially request approval for specific components of the Plan (both actual and demonstration programs) to maximize the amount of success in the early years.

XX e

e e

g s

O v

Additionally, Phase I will involve the evaluation and development of organizations and methods required to implemer.t the Plan.

Analytical tools will be prepared to provide a rapid means of review and verification of each component of the Plan.

Phase II will be an evaluation phase in which the programs that have been implemented will be judged for cost-effectiveness.

The programs will, be monitored through the use of extensive load research, customer surveys, field reports and cost accounting.

Only after a critical review, by both the Company and its regulators, will individual components of the Plan be allowed to continue on a widescale basis.

Phase III will involve the full-scale implementa-tien of those components which have been judged beneficial to the Company and its customers.

During this phase GPU will submit annual reports which will detail the year's conservation and load management activities, customer I

impacts, load shifts, and updated cost-effectiveness calculations.

I Siriking a balance over the next decade between reasonable demand growth and prudent expansion of supply will require a joint and careful ef fort by xxi

regulators, the Company and its customers.

The programs Proposed in this Plan are designed to attain this balance at a minimum cost while conserving energy.

Dear Mr. Calabrese:

In'rceponse to your request for information related to coal conversion, we of fer the following information and comments which are based upon updatir.;;

studies cocpleted in prior years for the FEA.

Item Us. 1:

~

Jersey Central Power & Light Company has no base load fossil plants in Ncv Jersey that have the ability to be converted to coal.

There are three stations with intermediate peaking units that burn oil that have the ability to be abic to be conver:cd to coal; however, there are o:hcr factors that must be considered such as the a:;c of facili:ics and the fact tha: canstruc -

tion expenditures for other than pollutien control devices vauld be required, the lack of t ransporta: ion facilities to supply coal and the limita: ion of the type of coal because of boiler design which require Icv fusion coal.

The studies assume that any transportation facilities required would be available at the completion of the conversion.

The minimum conversion period to install necessary pollution equipment and make other required modifications is three years. Other items required are bsrges for shipping cosi and availability of railroad cars as such shipping facili-ties are not currently availabic.

The units are also anticipated to be retired in the 1998-1999 pisaninc period due to sge and having served its useful economic life. Assuming the three year conversion period,

.the plant has a remaining life af ter conversion of 16 years and based upon an esti=sted conversion cost of

$95 million (1977 FEA costs esesisted), simost $400 pe r )*'J.

The cost pe r K'4 o f s new plant today is about

$600, however a ncv plant has more than 2 1/2 c'mes the life of these units.

Transportation equipment is not readily available.

It would al.so take shout three years to completc the conver-sion. The plant is scheduled to be retired in 1993.
