Enwave and Brookfield

Enwave Chicago has been a part of Enwave Energy Corporation (Enwave) and its parent company Brookfield Infrastructure Partners since August 2014.

Enwave now owns and operates 12 district energy systems in the U.S. and Canada:

Enwave Charlottetown. The Charlottetown, Prince Edward Island, system in Canada serves more than 100 customers with hot water, mainly for space heating. Its 250,000 lb/hr capacity system is fueled by biomass, municipal waste to energy, and fuel oil (for backup).

Enwave Chicago. Enwave Chicago provides sustainable 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 which use ice-storage technology.

Enwave Houston. The downtown Houston system currently pumps 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% 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. Enwave owns and operates two systems in Las Vegas. One 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. The other serves one of the largest resort-hotel-casinos on the main Las Vegas strip and has a capacity of 187,600 lb/hr of steam and 32,420 tons of chilled water.

Enwave London. Slated for further expansion over the next several years, the London, Ontario, system serves 60 customers with steam, largely for space heating and cooling use. It has a capacity of 200,000 lb/hr of steam and 4,200 tons of chilled water. It sells electricity to the grid from its 18 MW combined heat and power system.  

Enwave Los Angeles. The Los Angeles system serves hotels, office buildings and residential towers in LA’s Bunker Hill and Century City neighborhoods. It has chilled-water capacity of 35,300 tons and a 7.8-mile distribution network.

Enwave New Orleans. Built in 1999, the New Orleans system 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 square feet of building space within a 15-square-block area. The company also provides steam to critical and non-critical buildings in the district. 

Enwave Portland. The Portland, Oregon, system serves customers in the Brewery Blocks, a five-block shopping and professional district downtown. It has a chilled-water capacity of 4,530 tons and a 2.5-mile distribution network.

Enwave Seattle. Enwave Seattle's network 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, which will cut 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. Toronto’s district energy system provides heating and cooling service to more than 150 customers in downtown Toronto, Ontario. The centralized steam heating system started in the 1970s; 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 Toronto received the International District Energy Association’s system-of-the-year award in 2011.

Enwave Windsor. Enwave’s plant in Windsor, Ontario, provides hot water, chilled water and steam to its customer, District Energy Windsor (DEW), for DEW’s district energy system. The system has nine customers and began serving steam and emergency power to its anchor customer, Caesar’s Windsor Casino, in 1997. Enwave Windsor’s cooling plant uses ice storage technology to help meet the cooling needs of 4,400 tons of contracted cooling capacity.

Brookfield Infrastructure Partners. Brookfield is one of the world’s largest investors, owners and operators of infrastructure assets globally across the utilities, transport, energy, communications infrastructure and sustainable resources sectors. Parent company Brookfield Asset Management is co-listed on the New York, Toronto and Euronext stock exchanges under the symbols BAM, BAM.A and BAMA, respectively.
