Global warming: Rising temps threaten power production

The Browns Ferry nuclear power plant in Alabama had to shut down several times last summer because the Tennessee River’s water was too warm to be used for cooling.

More partial and total shutdowns of older coal and nuclear power plants predicted as air, river temps get warmer

SUMMIT COUNTY — Lack of adequate cooling water supplies have already resulted in reduced production and even temporary shutdowns of several thermoelectric power plants, and global warming could exacerbate those problems, potentially cutting production by up to 19 percent in some places.

Just last summer, the the Browns Ferry Nuclear Plant in Alabama had to shut down more than once because the Tennessee River’s water was too warm to use it for cooling.

That problem will become more common, according to a group of researchers from the University of Washington and Europe, who projected impacts for the next 50 years. According to the study, the likelihood of extreme drops in power generation — complete or almost-total shutdowns — is projected to almost triple. Continue reading
