Natural Resources Canada – Community Energy Systems - Case study: Cornwall, ON In 1995, the first municipally-owned, hot water district heating/cogeneration system was opened in Canada. The Cornwall district heating/cogeneration system heats approximately 14 buildings, including hospitals, schools, recreational buildings, a municipal library, a senior citizens' residence, an apartment building and a government office building. • The system generates about 4 per cent of the city's electrical energy. • The Cornwall system replaced numerous fossil fuel fired boilers. • The combined production of heat and power has reduced fuel consumption by close to 30 per cent. • Cornwall Electric has lowered its dependency on outside energy suppliers and maintained its low electricity rates. • Local jobs were created for the construction and maintenance of the plant. Cornwall’s energy facility reduces fossil fuel consumption by 30 per cent. (Left) Cornwall’s heat exchanger captures the reject heat that is used in the district energy system. (Right) The facility is sound proof and was built in a residential area. Source: NRCan. Undated. Cornwall, Ontario District Heating System.

Natural Resources Canada – Community Energy Systems A.2 Community energy systems A community energy system represents the most effective approach that a community may take to manage its energy needs. The concept involves a network of energy users and providers, trading energy needs through a physical network of hot water piping. Energy users maybe residential, commercial or industrial and energy suppliers may include anyone with excess or reject thermal energy. Examples might include: industry, combined heat and power plants, solar collectors and municipal landfill sites. - Case study: Vancouver Central Heat Distribution Limited, a private sector operation in Vancouver began life in 1968 and is now in a prime position to take advantage of the high-density building boom in downtown Vancouver. After 35 years of operation, the system now supplies 170 buildings, of which 60 are condominiums, 75 are offices and 15 or so are institutional. Included in that list are the famous Steam Clock in Gastown, an excellent brewpub and General Motors Place. Even though this is a private undertaking there are very close ties with City Hall. Central Heat is treated much like any other utility and charged a ‘franchise’ fee is charged annually. In addition the City retains the right to undertake the street-based piping installation at a rate of ‘cost plus 20%’. This is to ensure that the roads standards are adhered to. In return, City Hall regularly consults with Central Heat regarding their citycentre planning activities to ensure compatibility of new developments with the district energy system. New businesses are also encouraged to establish in the area to take advantage of the stabilized energy prices. The locally owned and operated company provides the City planners with many benefits – the elimination of multiple stacks and the maintenance of view corridors. Architects benefit from increased flexibility of design – rooflines, etc. and building owners are quick to realize the fiscal benefit of eliminating mechanical spaces as land prices increase. The additional floor space is a major attraction.

In 1993, an area including 1.2 million inhabitants was supplied with district heating; 65 per cent of the buildings were connected to the district-heating grid. The target was set for 95 per cent connected to the grid by 2002. The district heating is almost exclusively produced through cogeneration of heat and power. • The city has the ability to achieve a 30 per cent reduction in CO2 emissions by the year 2005.
