Large parts of U.S. and Canada are at risk of insufficient power supplies during the extreme winter in 2022

A large portion of North America and Canada face elevated reliability risks this winter, except the extreme weather, more importantly, driven by factors such as higher peak demand and power plant retirements

When the electricity consumption is greater than the energy generated, the missing part of the energy will come from the battery storage, so the energy stored in the battery will drop.

A large portion of North America and Canada face elevated reliability risks this winter, except the extreme weather, more importantly, driven by factors such as higher peak demand and power plant retirements

NERC, North America’s grid reliability watchdog, is set to release its annual winter reliability assessment on Thursday. Hirst, the NERC director of legislative and regulatory affairs, said an extended cold snap can cause reliability problems. In a change from last year’s assessment, the Southeast, Alberta and Canada’s Maritime provinces face an elevated reliability risk during extreme weather this winter, according to Hirst.

The Southeast has lost 500 MW of generating capacity while demand has increased compared to a year ago. Power plants in the region have lower-than-normal coal stockpiles. In Alberta and the Maritime provinces, added generation hasn’t kept pace with growing electricity demand, according to Hirst.

The Electricity Reliability Council of Texas, the Midcontinent Independent System Operator and ISO New England again face elevated winter reliability risks during extreme weather. In New England, which is limited in its ability to import natural gas, storage tanks at oil-fired power plants are only about 40% full, down from 54% last winter, he said.

NERC recommends that power plant owners line up their fuel supplies for this winter. “Early action is essential,” Hirst said. “We’re calling on generators to take every necessary step to make sure their fuel supplies are adequate.”
