The "NEPOOL Model for Iong Range Forecasting of Electrical Energy and Derrand" has been used to produce this regional forecast, incorporating, for the first tiJne, some load punagement concepts. Specifically, controlled storage-type electrical

pace heating and water heating are assumed for the region resulting in about an 800 TM decrease in the otherwise expected 1995 winter peak. 'Ihe resultant annual compound growth rate for 1979 through 1995 is 2.0% for sumner peak, 2.7% for winter peak and 2.6% for energy. 'Ihis is a decrease in the growth rate of about 1.1% in winter peak and energy and 1.7% in surmer peak frcrn the April 1,1979 report.

Adequate reserves are indicated for the expected peak loads through 1991/92, assuming all five "NEPOOL Planned" units are in service as scheduled, even though tm units do not, as yet, have construction permits._,. Additional capacity vill be required for 1992/93 and beyond. However, with aporoximately 60% of the existing capacity in oil-fired units, energy deficierries could occur in the mid 1980s. It is eswblly critical that all non-cil-fired capacity be built as scheduled and that conservation and load management efforts be continued to prevent energy deficiencies and to achieve the lowest possible price for electric energy.

INTRODUCTION The New England Power Pool (NEPOOL) Agreement is an agreement among electric utility systems in New England. The systems making up NEP00L own or control 99.6% of all New England generation. The objectives of NEPOOL are: (a) to assure that the bulk power supply of New England and any adjoining areas served by Participants conforms to proper standards of reliability, and (b) to attain maximum practicable economy, consistent with such proper standards of reliability in the bulk power supply, and to provide for equitable sharing of the re-sulting benefits and costs. "hese objectives are accomplisheu through joint planning; central dispatching; cooperation in environmental matters; coordinated con-struction, operation, and maintenance of electric generation and transmission facilities; and through effective ccordination with other power pools and utilities situated in the United States and Canada.

SUMMARY

A. Load Forecast The current forecast of electrical power needs for New England is presented in Exhibit I. The forecast shnws coincident winter and summer peak loads and net energy for the total New England area for the period 1980-1995. These values axclude self-generation by end-users of electricity. As shown in Exhibit I, the New England annual (winter) paa; load is forecast to increase at a compound annual growth rate oi 2.7% from the 1979/80 actual weather-corrected value to 1995/96. The summer peak load is forecast to increase at 2.0% per year from the weather-corrected 1979 actual value to 1995, while net energy is expected to increase at 2.6% per year from 1979 actual to 1995. The "NEPOOL Model for Long-Range Forecasting of Electric Energy and Demand" was completed in July, 1977 and has since undergone exten-sive revision, testing, and verification. This Model has been used to develop Exhibit I. In addition to seasonal peak loads and net energy, a forecast of electric energy sales to ultimate customers, and a forecast of a number of the more important demographic and economic indicators for New England are shown for each forecast year in Exhibit II..

It is important to recognize while examining the forecast data, that the NEPOOL Model is a long-term forecasting model and, therefore, is not designed to project short-term swings around a long-term trend. In addition, for the first time, the currant forecast includes some load management in the form of thermal storage devices for electric space and water heating. These and other details of the forecast and its basic assumptions are pre-sented in a report entitled "NEPOOL Model-Base Forecast of New d England Electric Encrgy and Peak Load 1980-1995", copies of which will be available to regulatory bodies from NEPLAN or the indivi-dual NEPOOL Participants. B. Forecasting Methodology The NEPOOL electric energy and peak load forecasting Model is a dynamic simulation model composed of two maj or sectors: an economic /demograpnic sector, and a power sector. The incorpora-tion of an economic / demographic secter in the Model provides the internal capability to develop forecasts of the basic factors which determine the growth of electric energy use for a geographic region. The following description of the sequential steps per-formed 'o y the Model is presented in the interest of creatint a basic comprehension of the Model. Exhibits III through VII; provide a visual description of the Model structure. The Model is initialized (i.e., all variables assigned beginning values) at a given point in time, namely the year 1970. For each year after 1970, the levels of population, labor force and employ-ment are determined in the demographic / economic sector of the Model. (Actual values are used for key Model " variables" from 1970 to the latest date for which data is available. In calculating values for these items, it is assumed that the geographic region's economy and demography will not, in the long run, maintain a separate existence but, rather, the region's economy will function at a level of acti-vity that will just support the population levels, and vice versa. Therefore, the population forecast is not only based upon expected future birth and death rates, but also upon net migration. It is the net migration component of the population growth logic in the Model which links the demographic subsector with the economic sub-secter. The Model treats the demographic subsector is the source of labor supply and the economic subsector provide.= the demand for labor. In broad terms, when the demand for labor exceeds supply, the migration logic simulates the movement of people into the re-gion, and out of the region when labor supply exceeds demand. The population forecast developed in the demographic subsector is used to produce a forecast of the number of households via applica-tion of national projections of household formation trends. In addition, household income is determined from the employment fore-casts and forecasted future wage rates. The household and income projections are combined with income / appliance saturation functions to yield residential appliance saturations and the total number of appliances for most appliance types. Energy consumption by appliance type is determined using the number of appliances, average unit con-nected load and appliance daily load profiles. Other factors included.

in the residential energy consumption calculations are federal appliance efficiency standards, electricity price, heating oil price, price elasticity, and long-term (30 year average) expect-ed temperature conditions (for heating and cooling type loads). It is important to note that the Model is driven by national em-ployment growth rates by industry for the forecast period. The forecasted national employment growth rates currently used to drive the Model are secured from Wharton Econometric Forecasting Associates. Employment is forecasted in two separate components-- manufacturing and nonmanufacturing. Manufacturing employment is forecasted based upon the national j employment growth rates by industry modified by a regional cost j index. The cost index measures the cost of doing business in a state relative to the United States. The manufacturing employment projections developed in the economic subsector are transformed into dollars of value added by industry using regional productivi-ty growth rates and production employee information. Industrial electric energy consumption (excluding self-generation) is calcu-lated using-value added and electric energy use per dollar of value added by industry. Electricity prices and price elasticity factors are also included in the calculation. Nonmanuf:ccuring employment is forecasted as a function of state population levels (from the demographic subsector) and expected national employment and population trends. Nonmanufacturing em-p l oym en t from the economic subsector is used as the measure of energy activity in the commercial class of service. The number of employees, the electric energy use per employee, electricity 1 prices, price elasticitics, heating oil and gas prices and long-term temperatures are used in calculating commercial electric energy consumption. Total electric energy consumption is determined by summing usage in the residential, industrial, commercial, and miscellaneous classes. Seasonal (summer and winter) peak loads are forecasted by specifying a long-term peak temperature-profile for a day-type and month, and then summing the forecasted load for each of some 50 end-use components for each hour of the day (Exhibit VIII). Annual system load factor is calculated directly from the fore-casted energy (including line losses) and forecasted peak load. A more detailed description of the Model and its development is presented in the " Report on a Model for Long-Range Forecasting of Electric Energy and Demand" by NEP00L and Battelle Columbus Laboratories, June 30, 1977. In addition, Model documentation on Model changes since June, 1977 is available to the NEPOOL Participants for distribution to the agencies who received the original report. .-,n. .w,

Generation The current New England generation mix (as a percentage of total capacity) for the winter of 1979/80 and the projected generation mix for the winter of 1995/96 are as follows: 1979/80 1995/96 MW MW Base Load (not capable of daily on-line/ off-line cycling) Conv. Steam-Oil 2356 1714 -Coal 337 978 Nuclear 4314 8926 Subtotal 7007 31.9 11618 42.8 Intermediate Cveling Conv.

The guidelines are: 56 to 62% - Base Load Capacity (all additions to be nuclear) 16 to 20% - Intermediate Cycling Units (fossil-fired) 8 to 11% - Hydroelectric Peaking, Including Pumped Storage 9 to 12% - Internal Combustion Peaking As indicated in these tabuintions, New Enginnd wLil niet have a c h i e v eil its generation mix guidelines by the winter of 1995/96. Further 27,120 MW is not sufficient capacity to maintain ' system reliability in that year. More coal fired capacity capable of daily on-line/off-line cycling is under study by the member companies to meet the 1995/96 system load. The winter and summer rating of the existing system capacity as of Janu.ary 1. 1980 is shown in Exhibit IX. The scheduled recatings, retire ~ ments, authorized additions, purchases, and sales which are projected to occur during the period beginning January 1, 1980 and ending with the Winter of 1995/96 are shown in Exhibits X through XIII-A. Exhibits XIV and XV each respectively reflect the New England generation re-sources to meet forecasted winter and summer seasonal demands for the period 1980 through the winter of 1995/96. ; w-

D. Transmission Shown in Exhibit XVII is the backbone of the New England bulk power Transmission system, a network of 230 and 345 kV transmission lines. The New England 345 kV grid is interconnected to the rest of the United States with two 345 kV ties to New York, one from Massachusetts and one from Connecticut, and an additional 230 kV tie *to New York from Massachusetts. These ties to New York are further augmented by four 115 kV ties, three in Vermont and one in Connecticut. A 345 kV tie from Maine to New Brunswick connects the New England grid with the Maritime Power Pool in Canada. Transformers interconnect the 345 kV grid to the underlying lower voltage grid at numerous locations throughout New England. Future 345 kV additions are listed on Exhibit XVI and are shown geo-graphically on Exhibit XVII. These lines are required to satisfy three general criteria as follows: 1 To provide transmission capability to deliver output of new generation to the transmission grid. - To fulfill the need to supply power to load growth areas. To maintain system reliability standards throughout the expanding transmission system. The lines, listed on Exhibit XVI are cross-referenced in Exhibit XVIII, which lists the major reason for their need. When a line provides more than one function, it is listed under more than one category. The planned system provides an integrated transmission grid, which is ne-cessary for NEP00L operations, with resulting benefits such as: reserve sharing, economy interchange and mutual assistance during emergencies.
