August 27, 2020


PJM has issued another hot weather alert today across the region. Temperatures are likely to exceed 90°F with high humidity causing a steady rise in electricity demand. The five Coincident Peak (CP) demand days for 2020 in PJM are shown below in Figure 1. There is a strong risk that a new CP is set this afternoon as forecasters expect that today’s load will surpass 144,000 MWs by 5:00 PM EST.

We advise clients to curtail electricity usage this afternoon between 3:00 and 6:00 PM EST. Remember that every kilowatt in reduced demand during these peak hours this summer can lower your capacity cost, and possibly transmission costs, next year.
