A new development at Front and King called the Well, includes thermal water-storage that uses water from Lake Ontario to air condition buildings. Enwave Energy Corp., is working with Allied Properties REIT, RioCan REIT, and Tridel Corp. in this energy project.  Currently, this Deep Water Cooling system uses cold water from Lake Ontario and sends it through 75 buildings in Toronto downtown buildings such as Rogers Centre. The system saves an estimated 100 million kWH of electricity a year , enough to power a 530,000 person city for a month.  In a conventional system the building must chill and heat the water themselves.  The water storage unit will function like a thermal battery, storing cold water that can be used when there is demand in the King West area. It’s greener and uses renewable energy. See full article.
