As temperatures plunged this weekend, Americans in much of the country were told to turn down their thermostats and avoid using large appliances to prevent rolling blackouts. The cascading grid stress came at an awful time but was all too predictable to anyone paying attention.
The interconnected U.S. grid is supposed to be a source of resilience, but the government’s force-fed green energy transition is creating systemic vulnerabilities that politicians don’t want to acknowledge. Utilities and grid operators weren’t prepared for the surge in demand for natural gas and electricity to heat homes, which occurred as gas supply shortages and icy temperatures forced many power plants off-line.
The PJM Interconnection, which provides electricity to 65 million people across 13 eastern states, usually has surplus power that it exports to neighboring grids experiencing shortages, but this time it was caught short. Gas plants in the region couldn’t get enough fuel, which for public-health reasons is prioritized for heating.
Coal and nuclear plants can’t ramp up like gas-fired plants to meet surges in demand, so PJM ordered some businesses to curtail power usage and urged households to do the same through Christmas morning. Rolling blackouts were narrowly averted as some generators switched to burning oil. Americans in the southeast weren’t so lucky.
