Coincident Peak Alert for NYISO and PJM, August 10, 2020

PJM:

Temperatures throughout the northeastern U.S. are expected to approach or exceed 90°F this afternoon, driving electric demand close to 2020 summer highs.

Revised forecasts suggest that today’s PJM peak load will exceed 143,000 MW during hour ended 17:00. Figure 1 shows that today’s forecast will approach 2020’s peak demand day and will likely set the 4th highest coincident peak hour for the summer of 2020. Client curtailment efforts in PJM should be targeted between 4:00-6:00 PM this afternoon.
