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. 7,600 Figure 2.13 PPL Electric Utilities Corporation Historic & Forecast Peak Load 7,500 7,400 Megawatts 7,300 7,200 7,100 7,000 6,900 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 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. Electric Power Outlook for Pennsylvania 2008-2013 43
For Calendar Year 2008, three electric generation suppliers sold a total of 13.9 million KWH to retail customers in PPL’s service territory, or about 0.03 percent of net energy for load. PPL reported a 2008 peak load reduction of 163,447 KW and energy savings of 3.7 million KWH resulting from its Interruptible Service – Economic Provisions tariff schedule. Customers reducing load for economic conditions receive significant rate discounts. The peak load reduction from this program represents approximately 2.2 percent of the 2008 summer peak load. PPL’s Price Response Service permits customers to respond to market price signals by reducing a portion of their load. In 2008, an estimated 23,080 KW peak load reduction was achieved, with energy savings totaling 322,930 KWH. PPL also has a program for the reduction of the energy consumption of low income customers by providing a variety of weatherization measures. PPL is a member of PJM and ReliabilityFirst. 44 Pennsylvania Public Utility Commission
