PECO's 2009 summer peak load, occurring on Aug. 10, 2009, was 7,994 MW, representing adecrease of 9.4 percent from last year's peak of 8,824 MW, and the lowest level since 2004. The2009-10 winter peak demand was 6,728 MW or 0.7 percent below the previous winter's peak of6,777 MW. The actual average annual peak demand growth rate over the past 15 years was 0.7percent. PECO's current forecast shows the peak load increasing from the actual 2009 summerpeak load of 7,994 MW to 8,612 MW in the summer of 2014, or an annual growth rate of 1.5percent. The current forecast for 2010 is 977 MW or 10.7 percent lower than the previous forecast.See Figure 43.Figure 44 depicts the average of deviations in forecasts made one to three years in advance. TablesA21-A24 in Appendix A provide PECO’s forecasts of peak load and residential, commercial andindustrial energy demand, filed with the Commission in years 2000 through 2010.PECO has entered into a Purchased Power Agreement with Exelon Generation to provide energyand capacity for its POLR load throughout the forecast period. Other resources may be obtainedthrough purchases from the wholesale markets.In 2009, PECO purchased 1,034 GWh from cogeneration and independent power productionfacilities, or 2.5 percent of net energy for load. Contract capacity totaled 181 MW.For Calendar Year 2009, EGSs sold a total of 391 GWh to retail customers in PECO’s serviceterritory or 1.0 percent of total consumption, down from 1.5 percent in 2008. On the summer peakday, EGSs represented a load of 80 MW, or 1.0 percent of the total.PECO has identified 13 transmission projects involving reconductoring of existing lines, with inservicedates through 2013.PECO has developed commercial and industrial rate incentive programs to encourage customers tomanage their energy demands and usage consistent with system capabilities. In 2009, PECOcontracted 409 MW of customer load for participation in its curtailment programs. Only 118 MWwas called upon for a one-hour PJM mandatory testing event yielding 118 MWh of energy savings.PECO’s Energy Efficiency & Conservation Plan 63 includes 10 energy efficiency programs andeight demand reduction programs which are estimated to exceed the reduction targets of 1,186GWh and 355 MW at a total cost of $341.6 million.PECO is a member of PJM and RFC.63 Docket No. M-2009-2093215.48Pennsylvania Public Utility Commission
