Brookfield Asset Management is a proven infrastructure investor that owns and operates seven major district energy systems in North America: Chicago, Houston, Las Vegas, New Orleans, Seattle, Toronto and Windsor, Ont. Each of these systems has been developed with the particular needs and assets of the local community in mind. In Toronto, the cold water of Lake Ontario provides thermal energy for the Enwave district cooling system. Enwave Seattle recently installed a new boiler that can burn clean urban waste wood, making it possible to use renewable biomass as the primary source of fuel for its district heating system that serves approximately 200 customer buildings.
Enwave Chicago provides chilled-water service to more than 120 customers in the Loop, West Loop, South Loop and River North. The system began operation in 1995 and runs five chilled-water plants. Four of the plants use ice-storage technology that helps meet the cooling needs of 108,000 tons of contracted cooling capacity while reducing the consumption of fresh water compared to on-site cooling systems.
Enwave Houston currently delivers chilled water through 5.4 miles of pipe to air-condition 24 buildings including Minute Maid Park, home of the Houston Astros. With a record of 100 percent reliability since its launch in 1999, the 27,000-ton system uses ice storage technology to help keep central business district buildings comfortable in spite of summer’s high temperatures and humidity.
Enwave Las Vegas provides heating, cooling and emergency power to the Planet Hollywood complex, including the hotel/casino, an attached shopping mall and a hotel/timeshare building. The plant was built in 2000 and subsequently expanded to accommodate the addition of the hotel/timeshare on the property.
Enwave New Orleans serves the mission-critical New Orleans Regional Medical Center and nearby commercial buildings. The company’s 26,000-ton chilled-water plant with ice storage technology provides chilled water for air conditioning to more than 12 million sq ft of building space within a 15-square-block area. The company also provides steam to critical buildings in the district.
Enwave Seattle uses locally sourced urban wood waste to produce steam for its 200 downtown customers. Founded in 1893, the Seattle system converted to biomass in 2006, cutting the carbon footprint for the system and its customers nearly in half. Customers use steam for space heating, domestic hot water, sterilization, laundry and kitchen operations, and even distillation.
Enwave Toronto provides heating and cooling service to more than 150 customers in downtown Toronto. The centralized steam heating system started in the 1970s, while cooling service was added in 2004. The company’s innovative deep lake-water cooling system uses cold water from Lake Ontario as its clean, renewable and reliable cooling source.
Enwave Windsor provides cooling and heating to its customer, District Energy Windsor, for its district energy system that serves nine customers. The system began operation in 1997 and the plant also provides steam and emergency power through DEW to Caesar's Windsor Casino, the main customer on the district system. The cooling plant uses ice storage technology that helps meet the cooling needs of 4,400 tons of contracted cooling capacity.
