2009 Report - Pennsylvania Public Utility Commission

The actual average annual peak load growth rate over the past 15 years
was one percent. PPL’s five-year winter peak load forecast scenario shows the
peak load decreasing to 7,180 MW in 2009 and then increasing to 7,450 MW in
2013 at an overall average annual rate of 0.1 percent. The forecast shown in
Figure 2.13 depicts PPL’s annual peak load.

Tables 2.20-2.23 provide PPL’s forecasts of peak load and residential,
commercial and industrial energy demand from 1999 through 2009.
Net operable generating capacity of 8,485 MW (summer rating) includes
41.2 percent coal-fired capacity and 24.7 percent nuclear capacity. Natural gas
and dual fuel units account for 26.7 percent of the total. Independent power
producers also provided 163 MW to the system. In 2008, PPL purchased over 1.7
billion KWH from cogeneration and independent power production facilities, or
about 4.2 percent of net energy for load.
In October 2008, PPL Corporation filed an application with the U.S. Nuclear
Regulatory Commission for a license to build and operate a new, 1,600 MW
nuclear plant near Berwick, Columbia County, with a proposed in-service date of
2018. The existing two-unit Susquehanna nuclear power plant has a total capacity
of 2,332 MW.
