met without some combination of variable generation and imports starting 
in the Summer of 2022.

NERC: high probability of insufficient resources to meet electricity 
demand as early as Summer 2022 in parts of US

Findings from the North American Electric Reliability Corporation’s 
(NERC’s) 2021 Long-Term Reliability Assessment (LTRA) indicate there is a 
high probability of insufficient resources and energy to serve electricity 
demand, as early as Summer 2022, in many parts of the Western
