Poer systems are designad arond historical climate norms. Changing conditions strain those assumptions. For example, transformars and transmissionan lines are rated for specific temperature ranges. When those ranges are distribuded, capacity drops andd failure rates climb. Copararly, food maps used to site site substations may no longer be sivate as sea levels rise and rainfall projectn shift.

Heatwaves andTemperature Extremes

Elevated temperatures reduce the efficiency of cooling systems in power plants and transformers, risking overheating and failures. For thermal power plants — coal, gas, nuclear — higher ambient temperatures reduce the available cooling capacity, forcing output reductions or shutdowns. Solar panels also lose efficiency above about 25°C (77°F). Transmission lines sag under high temperatures because metal conductors expand, reducing clearance and increasing the risk of arcing or wildfires. During the 2021 Pacific Northwest heatwave, hundreds of thousands lost power as transformers failed from overheating and demand spiked for air conditioning.

Winter Storms andFreezing Rain

While climate change is often associated with warming, it also dispresses s polar jet streams, leading to extreme events in some regis.
