With an additional 4,475 MW of planned newcapacity, the reserve margins are expected to meet the PJM percent reserve margin target through2016. If an additional 7,951 MW (18.4 percent) of conceptual seasonal capacity is included, thereserve margin remains adequate beyond the forecast period.The MISO net internal peak demand for summer 2009 is projected to be 100,100 MW. Forsummer 2018, the net internal demand is projected to be 109,400 MW, or an equivalent compoundgrowth rate of 1.0 percent. The MISO market has 121,769 MW of net capacity resources for the2009 summer. The amount of proposed increase in capability for summer 2018, including 19.1percent of conceptual seasonal capacity, is 4,542 MW.Electric Power Outlook for Pennsylvania 2009-2014 67
