In a March 18 op-ed, Mark J. Perry cited a study claiming there would have been blackouts throughout the PJM Interconnection electrical grid had coal not been available during the 2018 cold snap. He also asserts that a large percentage of natural gas was not available during that cold weather event. PJM has addressed this report numerous times; it is simply not true.

PJM’s operations are designed to ensure both reliability of power supply and competitive prices for customers. We dispatch generators based on the lowest cost resources available to meet demand.
