DESCRIPTION OF JERSEY CENTRAL Page 1 of 2 TRANSMISSION MAP AND GPU STSTEM MAP The Transmission Map of the Company's electric system (JC) shows in schematic form the basic elements of the Company's transmission and generating systems. The f

legend in the lower left-hand corner is color-coded to identify the ope ating voltage of each particular facility.

Major generation sources within the Company's service territory include the Oyster Creek plant south of Toms River, in the southern part of the State; the Sayreville and Werner stations located on the Raritan River; the Yards Creek Pumped Storage Hydro Plant in the Kittatinny Mountains in the northwestern part of the -

State; the Gilbert Station on the Delaware River; and a major combustion turbine installation at Glen Gardner.

i The Ccmpany also shares in the ownership of the Keystone Generating Plant located in Johnstown, Pa. and the Three Mile Island Nuclear Station located j

near Harrisburg, Pa.

The Three Mile Island Plant is jointly owned by Jersey Central, Metropolitan Edison, and Pennsylvania Electric, all of which are operating subsidiaries of the GPU, General Public Utilities, system. These facilit!:s are shown on the General Public Utilities System Map dated June 1,1080.

~

Power generated at the Keystone Plant is transmitted to New Jersey over a 500,000 volt transmission system. This system is shown on the General Public i

l Utilities Systes >bp and is identified in a red color. The basic elements of that system include transmission facilities connecting Keystone,Juniata, Alourtis, Three Mile Island and Br.nchburg. Power is transformed to 230,000 volts at the Branchburg Subststion of Public Service and transmitted into New Jersey and the 1

Jersey Central service territory over 230,000 volt transmission. lines. Power

]

generated at Three Mile Island is also transmitted to Jersey Central over the i

2-Page 2 of 2 500,000 volt and 230,000 volt transmission system.

Referring to the transmission map of Jersey Central, power is transmitted intervally over the Company's 230,000 volt und 115,000 volt transmission system 1

to switching stations white interconnections are made with other high voltage lines and where voltage is stepped down to 34,500 volts. The subtransmission system which operates at 34,500 volts is shown as anorange color on that exhibit. Power is then supplied to local distribution sube*.ations through the 34,500 volt transmission systam.

Dear Mr. Dieckamp:

On behalf of Mr. Niitenberg, I would thank you for your letter dated September 26, 1900 on the subject of our understanding of,our discussions at the meeting in Newark on Septe=ber 2.

Your letter does reflect our understanding of cur current status and direction and, accordingly, I am returning to you the original signed by Mr.

Niitenberg and dated October 6, 1980 for your records.

We have retained the copy signed.by you which is like-wise signed by Mr. Niicenberg and dated October 6,1980 for our records.

In view of the slowdown in call pickup from.

Canada, I have asked Ken McClysont to connunicate with Rit Bright or Bob Sims so that you will know that this signed letter is on the way to you.

With best regards.

Yours very truly, j

Mr. Arvo Niitenberg Executive Vice President i.

Ontario Hydro 700 University Avenue 3.:m s -

Toronto, Ontario MSG 1X6 p..e s c..

r Jear Mr. Niitenberg:

I believe it useful to review the current status of our progress trward the installation of a tie between the Ontario Hydro and GPU systems and the purchase by GPU's subsidiary, Jer s r-Central Pcwer & Light Company, of energy and capacity through 1.ae tie.

This letter reflects the results of our meeting on September 2 in.awark, New Jersey.

Our organizations continue to have a high degree of interest in the project ad will both continue to attempt to reach a point, in the near future, where a firm statement of our mutual under-standing might be e::; ressec.

Construction of the tie will pro-vide reliability benefita to both the Ontario Hydro system and the GFU/PJM systems.

Further, we both see an opportunity for signifi-cant matual economic benefits by making capacity and energy avail-able between the two systems.

We recogrize that the institutional and environmental constraints within which we both operate--and which are more ccmplex in an international setting--will require extensive further discussions bet'..een cur crganizations and with our regulators and governmental agencies before a firm understanding can be reached and implemented.

In this connection, we have instructed our representatives to con-tinue worki n on the contract, licensing and approvals phase of the project.

Because both of our cofanizations stand to benefit by meeting the projected inservice aate of December 31, 1984 we have agreed to go forward and jointly share the costs of certain services which are required to maintain the project schedule.

These jointly chared costs are estimated to be about $2 million (U.S.) through June 1981 for the lake survey costs, and a forecast $2 million (U.S.)

frca June 1931 thrcugh December 1981 for contract costs associated with cable design and manufacturing necessary to maintain schedule.

j This latter cost remains to be ccmaitted.

We have each expressed a variety of concerns about the project as we have progressed.

These include the technical feasibility of the project, including'the reliability of construction cost and timing estimates; the financial viability of earsey Central and GPU; the economics of the transaction, including the method of pricing energy and capacity and provision for taxes and en-vironmental charges which might be impoced on such sales; and the environmental concerns surrounding the generation and trans-mission of electric energy.

Our organizations continue to believe that these matters can be successfully resolved to our mutual sat-isfaction and to the satisfaction of the governmental authorities to whcm we are accountable.

With respect to one of these issues--the pricing of the energy--

we recognize your organization's strongly he]d philosophy that there must be a recognition of the value, as well as the cost, in the transaction.

A value-oriented pricing mechanism is not, in principle, unacceptable to us as long as it is designed to rec-ognize the fact that our system will make a significant capital investment in the tie and that the definition of cost is vulner able to externally imposed factors that could significantly in-fluence the level of incentive perceived in the differential between cest and value.

In order that we might keep a careful watch on the progress of this projE Ot, it is agreed that we plan to meet early in December.

This will give us an opportunity to review the many factors present in our ongoing efforts and the progress made toward their satisfactory resolution.

If the above is consistent with your understanding of our current status and direction, I would appreciate the return of a counter-signed copy.

Very Truly yours, l
