Combined Heat and Power (CHP)
Combined Heat and Power generators produce electricity from natural gas and capture the waste heat produced during the generation process. This type of production has several advantages over traditional electricity generation:
Thermal energy produced during generation typically goes to waste. By capturing it on-site it can be used to meet heating needs on site.
Electricity produced on-site doesn't have any of the typical losses during transmission experienced by traditional distribution networks.
In Alberta natural gas is cheaper and more consistent in price than electricity, making it more economical to have as the primary energy source on site.
One significant limitation of CHP systems is the availability of heat: a CHP is intended to run as much as is needed to produce electricity for any given site. They can produce the thermal energy needed to heat a site, but running constantly to supply continuous heat is very wasteful. To solve these deficits GSS has paired CHP units with thermal storage technology- when the unit is running and heat isn't needed the excess thermal energy is stored in an underground borefield. This uses the earth as a large thermal battery, storing and extracting thermal energy with a high degree of efficiency.
