COGENCanada Combined Heat and Power (CHP) Association
Coming: Ottawa Seminar-Conference Oct.1-2, 2014
Edmonton Seminar Oct. 7-9/2014

Mission: COGENCanada is a federally incorporated, not-for-profit association promoting cogeneration & sustainable industrial development. We help energy users, electric generators, Industrial Development people and cogen suppliers. We put on seminars and courses (see tab).
The following two illustrations show how cogeneration can take heat rejected by one energy process and use it in another rather than losing it to the environment:
Single purpose thermal electric power plants reject some 50% of the fuel heat to water bodies or the atmosphere. Cogeneration can recover this heat and use it to displace fossil fuel. If you experience winter, you probably have used a cogeneration system. The engine and heating system of an automobile are a cogeneration system. The engine provides mechanical power to the wheels, from the heat of combustion of the gasoline. At the same time, the engine releases heat for the passenger compartment & the defroster.
COGENEurope uses the following definition: Cogeneration (Combined Heat and Power) is the simultaneous production of electricity and heat, both of which are used.

Using Recovered Heat to Displace Fossil Fuel

In Cogeneration-based Eco-Industrial Networks, heat rejected by the Cogeneration system and other processes in the Network is used by other processes in the network. This provides Environmental & Economic Benefits – Clean Energy as well as other benefits as explained

Cogenerated Electricity is as Green as wind or solar but delivers electricity whether or not the wind is blowing or the sun is shining

Single purpose thermal electric power plants reject some 50% of the fuel heat to water bodies or the atmosphere. Cogeneration systems recover this heat which is rejected by the electric power cycle and use it to displace fossil fuel

There is a need for an incentive to buy cogenerated electricity, particularly at night, thus to facilitate making recovered heat available for use in industrial processes or for space heating to displace fossil fuel day and night. The cogeneration system should operate 24 hours per day because the process heat is required 24 hour per day. The electricity must be sold at night which can be a problem due to the low price. Ontario electricity could, in effect, be stored in Hydro Quebec reservoirs at night and returned to Ontario in the morning. There are other storage options. Cogenerated electricity is as green as wind or solar so there should be an incentive to buy it.
