"Summer Heat Threatens Power Grid Across US"
Two-thirds of North America is at risk of energy shortfalls this summer during periods of extremely high electricity demand, warns the North American Electric Reliability Corporation (NERC). Although all 20 NERC assessment areas have adequate power resources to meet normal peak summer demand this year, certain areas are at elevated risk of electricity supply shortages if confronted with more extreme summer conditions, including the U.S. Western Interconnection, SPP, MISO, ERCOT, SERC-Central, and New England. The combination of higher electricity demand and reduced supply can cause energy shortfalls.
