District Heating Could Service 30% of Canadian Buildings by 2030 (Part 2)

Following are a sample of Canadian DE initiatives underway and links to websites with more information:

The Town of Markham

Markham District Energy Inc. (MDE), an energy company owned by the Town of Markham owns and operates an award-winning EcoLogo certified community energy system that produces thermal energy and electricity for its emerging downtown and the growing urban development surrounding Markham Stouffville Hospital.

Currently, three energy plants are operating on a district energy system in Markham Centre serving over six million square feet of mixed-use development. MDE commenced construction of a second district energy system in 2010, which is located in East Markham with the expanding Markham Stouffville Hospital as an anchor energy customer.

The City of Hamilton

Operating a powerful, clean burning, natural gas-fired reciprocating engine connected to a generator and three 4 MW gas-fired boilers at its primary facility, Hamilton Community Energy (HCE) leverages cogeneration heat and power technology to produce and supply thermal energy through a network of insulated underground pipes for heating, domestic hot water, electricity and cooling services. Exhaust heat is captured and used to produce 3.2 MW of additional thermal capacity.

In addition, HCE has partnered with McMaster Innovation Park to provide ground breaking geo exchange and solar thermal technologies that fully integrate district and renewable energy at a new satellite district energy operation.

HCE's award winning primary facility together with its other operations offers sustainable energy solutions that align with Hamilton's Vision 2020.

City of London, Ontario and Charlottetown, PEI

The district energy systems, located in Charlottetown, Prince Edward Island, and London, Ontario, together have approximately 185 megawatts (MW) of thermal and electric generation capacity. These stable, long-term investments provide reliable operational service and excellent growth opportunities for providing steam and chilled water to new and existing customers.

The London cogeneration facility, a 17 MW power generation facility, was placed into service in December 2008 under a 20-year contract with the Ontario Power Authority. This new facility also provides approximately 52 MW of incremental thermal energy to the London district energy system to expand its steam and chilled water capabilities.

ENMAX Calgary Downtown District Energy Centre

The ENMAX Calgary Downtown District Energy Centre owned by ENMAX located at 9th Avenue and 4 Street SE began operations in March 2010 providing heat to its first customer, the City Municipal building. This heat generating facility is capable of providing heat for up to 10 million square feet of new and existing residential and commercial buildings. The Bow Valley College New South Campus was the first building in Calgary to be constructed without a furnace and will be heated by the DE system as will the commercial and residential buildings in the East Village.

City of Strathcona, Alberta

The Community Energy Centre in the City of Strathcona near Edmonton has been designed and constructed to the LEED® Silver (Leadership in Energy and Environmental Design) standard. In late October 2005, the centre began the LEED® certification process. It is now the first LEED® certified building in Strathcona County.

The community energy system delivers hot water from a central source through insulated underground pipes to heat buildings. Natural gas will be used as the fuel to heat the water.

The City of Yellowknife, NWT

The City of Yellowknife is evaluating the potential for a community energy system to provide heating services to buildings in the downtown core using heat from an abandoned mine, the Con Mine. This innovative concept involves recovering heat from the abandoned Con Mine approximately 1km outside of downtown Yellowknife to heat buildings via a network of distribution piping. Biomass and heating oil is also going to be available to top up the heat provided by the mine.
