Summary of EDC Data The following sections provide, for each jurisdictional EDC, historic and projected energy sales and peak load, electric generation supplier sales statistics, purchases from cogeneration and small power production projects, planned transmission line additions, and conservation activities. Duquesne Light Company Duquesne Light Company (Duquesne) is the principal subsidiary of DQE Holdings 49 and provides electric service to 578,094 electric utility customers in the City of Pittsburgh and portions of Allegheny and Beaver counties in Southwestern <strong>Pennsylvania</strong>. In 2010, Duquesne had energy sales totaling 14,110 GWh – up 1.7 percent from 2009. Commercial sales continued to dominate Duquesne's market with 47.6 percent of the total sales, followed by residential (30.7 percent) and industrial (21.2 percent). Average annual use per residential customer was 8,235 kWh at an average cost of 11.82 cents per kWh; operating revenues totaled $924 million. The current five-year projection of average increase in total energy consumption is 0.3 percent per year. This includes a residential growth rate of 0.7 percent, a commercial rate of 1.0 percent and a major decline in industrial sales of 1.8 percent per year. See Figure 12. Duquesne's summer peak load, occurring on July 23, 2010, was 2,889 MW, representing an increase of 5.7 percent from last year's peak of 2,732 MW. The 2010-11 winter peak load was 2,281 MW or 7.5 percent higher than that of the previous year. The actual average annual peak load growth rate over the past 15 years was 0.5 percent. Duquesne’s forecast shows the peak load increasing from 2,889 MW in the summer of 2010 to 3,125 MW in 2015, or an average annual growth rate of 1.6 percent. The current forecast for 2011 is 2.8 percent above the previous forecast, filed in 2010. See Figure 13. Tables A01-A04 in Appendix A provide Duquesne’s forecasts of peak load and residential, commercial and industrial energy demand, filed with the <strong>Commission</strong> in years 2001 through 2011. PJM manages the flow of wholesale electricity for Duquesne. Duquesne’s integration into PJM involved transferring control of 670 miles of high-voltage transmission lines; however, ownership has remained with Duquesne. PJM is the regional reliability coordinator for Duquesne. For Calendar Year 2010, 19 EGSs and one municipality sold a total of 8,789 GWh to retail customers in Duquesne’s service territory, or 59.2 percent of net energy for load. Since joining PJM in 2005, PJM has provided energy imbalance service to all load-serving entities, which includes the EGSs. 49 On April 24, 2007, the <strong>Commission</strong> approved the acquisition of Duquesne Light Holdings Inc., by merger, with the Macquarie Consortium. Headquarters remain in Pittsburgh. See Docket No. A-110150F0035. 24 <strong>Pennsylvania</strong> <strong>Public</strong> <strong>Utility</strong> <strong>Commission</strong>
