PJM Interconnection LLC, America's largest power grid company, warned that extreme heat this summer could trigger a power shortage for the first time. PJM is the center of electricity supply for approximately 20% of Americans from the Midwest to the East Coast of the United States. This summer is expected to be hotter than previous years, particularly in the East Coast states. PJM notes that through the demand response plan, the company also has 7.9 gigawatts of backup power supply. The plan forces commercial, industrial, and even domestic users who have joined to reduce electricity use to keep the grid stable in the event of an emergency. Although it is impossible to predict the possibility of extreme situations, PJM's warning highlights the demand constraints faced by power grids that have recently been oversupplied.
