Electric Power Outlook - Pennsylvania Public Utility Commission

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 Pennsylvania. 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 Commission 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 Commission approved the acquisition of Duquesne Light Holdings Inc., by merger, with the
Macquarie Consortium. Headquarters remain in Pittsburgh. See Docket No. A-110150F0035.
