NPPD serves approximately 350 cities, towns, and other power districts representing about
760,000 residents of the state of Nebraska. NPPD's Project No. 1835, a baseload
hydroelectric facility, is part of the electric utility system used to supply this power. Under
the terms of a contract with Central, the operation of Project No. 1835 is coordinated with
Central's Project No. 1417. Under power sales agreements between the two districts,
Central sells all the power produced at the Project No. 1417 powerplants to NPPD at
wholesale.
NPPD periodically completes a comprehensive 30 -year forecast of future power demands
and energy use. NPPD uses econometric models to estimate the number of customers,
energy use, and peak demand. The most recent forecast is entitled "Summary Report of the
Nebraska Public Power District Load Forecast 1993 - 2030." NPPD files the forecast with
the Nebraska Power Review Board and the Mid - Continent Area Power Pool.
NPPD forecasts summer peak demand to grow from 1,810 MW for 1993 to 2,636 MW in
2023, an annual growth rate of 1.26 percent. Existing demand -side management programs
are included in the forecast. In addition to this base forecast, NPPD examines demand
growth under variable economic and weather scenarios (Table 1 -1).

As shown in Table 1 -1, the system load factor is anticipated to rise over the forecast period.
While winter peak demand is forecasted to grow more rapidly than the summer peak, the
summer peak remains higher than the winter peak throughout the forecast period (2,636
MW summer versus 2,169 MW winter in 2023). NPPD estimates that additional capacity
will be needed in approximately the year 2008.1' In the absence of the projects, this date
would be advanced about 4 years.
