Google to convert Alabama coal plant into renewable-powered data centre

Technology company says it will open 14th data centre at Widows Creek site in Jackson County that will be powered with 100% renewable energy

Google will convert an old coal-fired power plant in rural Alabama into a data centre powered by renewable power, expanding the company's move into the energy world.

The technology giant said on Wednesday that it would open its 14th data centre inside the grounds of the old coal plant, and had reached a deal with the Tennessee Valley Authority, the region's power company, to supply the project with renewable sources of electricity. With the coal plant rehab, Google solidifies a reputation among tech companies for promoting clean energy.

"It's very important symbolism to take an old coal plant that is a relic of the old energy system and convert it into a data centre that will be powered by renewable energy," said David Pomerantz, climate and energy campaigner for Greenpeace.

Michael Terrell, who leads energy market strategy for Google's infrastructure team, said the company saw clear benefits in taking over the old coal facility. "There is an enormous opportunity when you take over the infrastructure that is there - the transmissions lines and the water intakes - and use that to power a data centre that is powered by renewable energy," he said.
