Dear Dr. Bauer:
In a letter of December 27, 1977, addressed to me as. Chairman of the ECAR Executive Board, the Economic Regulatory Administration of the U. S. Department of Energy, identified seven items pertaining to coordinated regional bulk power supply programs which are to be reported by the regional electric reliability councils. These items replace the reporting requirements which were identified in Appendix A-1 to FPC Order 383-4.
In addition, each council is to provide an executive summary of significant changes since their previous report.
The ECAR response consists of two volumes as follows:
Volume I contains an opening statement which identifies ECAR and the ECAR region; a description.of the Report Content and Organization; a discussion of ECAR procedures; a summary of changes from the previous response; a/td the responses to Items 1 through 7.
Volume II contains the information provided under Item 8, Additional Material for Clarification.
It includes the data provided by each reporting utility for Items 1 through 4, as well as a summation of the data provided by ECAR Bulk Power Member Systems and ECAR Liaison Member Systems.
As requested, five copies of each of the above volumes are being made avail:11e to you as Assistant Administrator for Utility Systems; two copies will be sent to the Chief, Office of Electric Power Regulation, FERC; and two copies will be sent to the public utility commission -in the states of Indiana, Kentucky, Maryland, Michigan, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia.

FOREWORD s
' {y' Twenty three electric utilities operating in FPC East Central Region II consummated the East Central Area Reliability Coordination Agreement on January 14, 1967. This agrewment created an organ-1:ation called ECAR, the stated purpose of which is "...further to augment reliability of the parties' bulk power supply through coordination of the parties' planning sid operation of their gener-ation and transmission facilities." Three additional electric utilities subsequently joined ECAR.
Its bulk power membership currently consists of 26 companies (19 systems) as follows:
Appalachian Power Company (AEP)
Cincinnati Cas & Electric Company Cleveland Electric 111uminating Company Columbus and Southern Ohio Electric Company Consumers Power Company Dayton Power and Light Company Detroit Edison Company Duquesne Light Conpany East Kentucky Power Cooperative Indiana G Michigan Electric Company (AEP)
Indiana-Kentucky Electric Corporation (OVLC)
Indianapolis Power 4 Light Company Kentucky Power Company (AEP)
Kentucky Utilities Company Louisville Gas and Electric Company Monongahela Power Company (APS)
Northern Indiana Public Service Company Ohio Edison Company Ohio Power Company (AEP)
Ohio Valley Electric Corporation Pennsylvania Power Company (OE)
Potomac Edison Company (APS)
Public Service Indiana Southern Indiana Gas and Electric Company Toledo Edison Company f
West Penn Power Company (APS)
V To achieve its purpose and objectives, the ECAR Agreement provides for the establishment of a formal organization consisting of an Executive Board, Coordination Review Committee, Advisory Panels, and a permanent staff. The Executive Board and the Coordination Review Committee each have 19 repre-sentatives since the subsidiaries of American Electric Power, Allegheny Power System, Ohio Edison System, and Ohio Valley Electric Corporation are treated in each case as one system. ECAR is the entity which has responded annually since 1970 to the Federal Power Commissior's Docket R 362, Order 383 4,eatitled, " Reliability and Adequacy of Electric Service-Reporting of Data."
Responsi-bility for the bulk power supply planning and coordination reporting program, established under Section 202(a) of the Federal Power Act, was shi,f ted to the Econonic Regulatory Administration of the l
Department of Energy _in 1977.
l The ECAR area covers all or portions of eight states: Indiana, Kentucky, Maryland, Michigan, Ohio, Pennsylvania Virginia, and West Virginia. A very small portion of one ECAR member's system extends into the northern portion of a ninth state, Tennessee. The location of this area can be de-scribed furthe. as being within the boundaries of FPC East Central Region !!, plus the eastern most I
portion of the upper peninsula of Michigan.
j gg An FPC tabulation. based on 1968 inforastion, Indicated approximately 370 other electric utilities in the ECAR region, composed of cooperatives, investor owned, and municipal systems. These s
i
~=
370 stilitiss wers effarded thi opportulity far 1::vstven:nt la ECAR thriugh ca ECAR Lisissa Committe, which was established by an April 7,1970, supplement to the ECAR Agrcement. The supplement f
recognie,
the impracticality of direct involvement by all 370 ut!!! ties, as it stipulates that each of the classifications (cooperatives, municipals, investor owned systems, and ECAR bulk power members) wi %
each state is to select and appoint one representative to the Liaison Committee. This Committee ace, as a liaison between the EC'.R Executive Board and all utilities in the area, and thus provides a two.
way communication channel on matters relating to reliability of bulk power supply. This ECAR Liaison Committee established a procedure through which system data were solicited from the liaison members for inclusion in this response.
9 REPORT CONTENT The Economic Regulatory Administration of the U.S. Department of Energy, in a letter addressed to the Chairman of the ECAR Executive Board dated December 27, 1977, identified seven items pertaining to coordinated regional bulk power supply programs which are to be reported by the regional electric reliability councils. These items replace the reporting reqr tements which were identified in Appendix A-1 to FPC Order 383-4.
In addition, each council is to provide an executive summary of significant changes since their previous report. An eighth ites, Additional Material for Clarifica-tion, may be included if desired. The ECAR response identifies the reporting requirements for each of these seven items and addresses each one in turn.
The material contained in this report has been developed, accumulated, and compiled over a period of several months. Certain of the system data provided have also been used to satisfy other reporting requirements. Nevertheless, an attempt has been made to provida the best data available at the time of publication. Due to changing circumstances, certain of the system information will undoubtedly have been updated prior to the April 1978 issue date for this report to satisfy other reporting requirements.
REPORT ORCANIZATION The report consists of two volumes as follows:
Volume I contains an opening statement which identifies ECAR and the ECAR region; a descrip-tion of the Report Content and Organization; a discussion of ECAR procedures; a summary of changes from the previous response; and the respon'ses to Items 1 through 7.
Volume II contains the information provided under Item 8 Additional Material for Clarification.
It includes the data provided by each reporting utility for items 1 through 4 as well as a summation of the data provided by (a) ECAR Bulk Power Member Systems; ard (b), ECAR Liaison Member Systems.
Previous ECAR responses consisted of five volumes as follows:
l Volume I
- Load Projections And Resource Planning Volume II System Performance And Transmission Planning Volume !!! - Area Controls, Communication, And Emergency Preparedness

Th3 ECAR summariss is Vstume I pert:lacd salsly to ECAR Bulk Pawsr Membtr Systs s and the information pertaining to ECAR Liaison Member Systems appeared only in Volume IV. The revised reporting instructions for this year's response specify that the report for tho reliability council is to include information from significant interconnected non members within its service territory
/FA that have responded to data requests. For purposes of this report, ECAR has assumed that those systems in the region that prepare a " Monthly Power Statement" (FPC Form No. 12E.2) should be classified as "significant". Information has been obtained from other utility systems in the regions and that is included in Volume II of this response. The data which these other utility systems pro.
vided is not as detailed as that provided by the utilities included in the "ECAR Total", and it has been tabulated in a different format.

ITEM 1
'd h ESTIMATED ENERGY AND PEAK DEMAND DATA FOR FIRST 10 YEARS The reporting form for this item lists the following:
1.
Actual monthly peak hour demand and net energy data for calendar year 1977.
2.
Estimated monthly peak hour demand and net energy data for calendar years 1978 and 1979.
3.
Estimated summer peak hour demand data for each summer season during the period summer 1978 through summer 1987.
4.
Estimated winter peak hour demand data for each winter season during the period winter 1978-79 through winter 1987-88.
5.
Estimated annual net energy data for each of the years 1978 through 1987.
The following definitions were provided by the U.S. Depart-ment of Energy for purposes of the report:
~_
Peak Hour Demand is the maximum integrated clock hour demand reported on the same basis as Net Energy.
Net Energy is the energy required from all power sources during the reporting period to satisfy the energy require-ments of customers and includes transmission system losses.
This data is reported in Gigawatt hours.
It includes the i
net energy from installed power sources and energy supplied by other sources such as interconnected utility systems and 1-1
--J l
industrial sources.
Special attention must be given to the handling of energy sales for resale to avoid duplicate
()
I reporting with other systems.
Net Energy does not include energy required for pumping of pumped storage generating plants.
For reporting purposes, summer is defined as that period of the year between June 1 and September 30.
Winter is defined-as that period between December 1 and March 31.
The period described as Winter 1978 begins on December 1, 1978 and continues to March 31, 15'79.
The data reported for ECAR was obtained by summing the data provided by each of the reporting utilities in the region.
(Refer to Item 8 for this data.)

The reporting forms for this item provide:
A - A listing of existing generating capability in ECAR as of the beginning of calendar year 1978.
B - A listing of all generating capability installations, removals, and equipment upratings and deratings projected in ECAR during the period January 1978 through December 1987.
C - A listing of all scheduled imports and exports that
[)
involve electric systems which are not included in the ECAR region.
The amount shown for each capacity exchange listed is the amount which is projected to be in effect at the time o.f the seasonal peak hour demand of P.e reporting ECAR utility for each summer and winter peak load season during the period summer 1978 through winter 1987-88.
Transactions have been

ITEM 3 A - RESOURCES, PEAK DEMANDS, AND MARGINS B - ASSESSMENT OF ADEQUACY OF ADJUSTED MARGINS The reporting forms for this item provide:
A - A tabulation of the estimated resources, peak demand, and margin for the ECAR region at the time of the pro-jected seasonal peak hour demand for each summer and winter season during the period summer 1978 through winter 1987-88.
The entries on lines 01 through 10 were obtained by summing the data provided by each of the reporting utilities in the region (see Item 8).
Line 11, Scheduled Outage, provides an indication of the level of planned maintenance expected in ECAR.
The estimate was prepared for purposes of this report (Ph only and is bas'ed on the IcVel of planned maintenance that is currently projected for the periods of heaviest load demand during the upcoming summer and winter
- seasons, i'.c.,
two percent of total installed capability during the summer of 1978 and five percent of total installed capability during the winter of 1978-79.
B - An assessment of the_ adequacy of the margins indicated for the initial five years of the reporting period.
The assessment is not couched in terms of the adjusted margin because in the appraisal procedure employed by ECAR scheduled maintenance requirements are treated in much the same manner as other facets of-unavailability of generating equipment.
The overall load characteristic-in ECAR is such that some amount of maintenance is j
scheduled throughout each month of the year.

-(f A - COORDINATION OF OPERATIONS j
B - LOAD PRESERVATION PROGRAM The ECAR material is provided by the following:
A- (a) Operating reserve policy:
ECAR Document No.
2,
" Daily Operating Reserve" which presents the daily operating reserve criteria adopted by ECAR members.
(b) Provisions for sustaining the operation of generating units on local loads:
ECAR Document No. 3, " Emergency Procedures During Declining System Frequency" presents the program adopted by ECAR members as a result of studies made of system performance under condition of declining system frequency.
(c) Procedures for coordination of maintenance outages for generation and trans 'ission facilities:
The maintenance of generation facilities within ECAR is coordinated by the semiannual issuance of a Load Ccpacity Forecast prepared under the auspices of the ECAR Operation Panel.
The data for this report is supplied semiannually by each system or operating pool.
From these reports a composite maintenance schedule along with a short-term load forecast and the reserve position of each system or operating pool is tabulated.
This information is then distri-buted to all ECAR companies for their use in refining their individual maintenance schedules.
The unex-pected outages of generating equipment during the forecast period may necessitate substantial revision of the maintenance schedules to minimize total down time and assure adequate reserves will be maintained s) by each of the ECAR entities and the area as a whole.

The maintenance of transm.tssion facilities is
(
coordinated between and among systems on a week-by week basis consistent with load levels, weather, and general system conditions.
As an integral part of the ECAR Daily Projection broadcast over the ECAR Teletype Network, all major transmission outages either scheduled or forced are shown, the date out of the facility, and its expected return.
Because of the nature and maintenance requirements of trans-mission facilities other than switchyard equipment, long-term advance planning for the maintenance o#
transmission facilities is normally not,done.
ECAR periodically issues a report entitled, "ECAR Facilities Outage Notification Table," which is used to identify important transmission facilities, together with a list of the companies who will be affected and are to be contacted when specific trans-mission facilities are forced out of service or k'
planned to be removed for maintenance.
~(d) Procedures for selection setting and maintenance of relays that affect the overall reliability of the interconnected network.
ECAR members have formulated a set of principles and procedures to be used by the ECAR member companies to appraise the adequacy of the, protection of their system, which are set forth in "ECAR Protective Relay Principles i
and Procedures."
