For the future, Telstra plans a major project to get rid of heat by using the water in its London Docklands surroundings to chill the water it uses.
"We've applied to British Waterways to dispose of 3MW of heat into the dock, which British Waterways has approved," Sell said. "We're just waiting on the Environment Agency." He explained the system will be a "massive heat exchanger" that makes use of the relatively cool waters of the wharf for chilling.
"That should give us almost year-round practically free cooling," he said.
