The world’s largest deep lake water cooling project just got bigger

Toronto is digging deep to expand what experts already consider to be one of the coolest and most environmentally friendly energy projects on Earth – the city’s deep lake water cooling system.

Toronto’s Enwave Energy Corp., which owns and operates the giant deep lake water cooling (DLWC) system, already has some 40 kilometres of underground water pipes that snake through Toronto’s downtown and extend about five kilometres into Lake Ontario. The lake pipes channel water to and from a downtown heat transfer station at Pearl Street (west of University Avenue, between Adelaide Street West and King Street West).
