A new report from Power Advisory demonstrates how combined heat and power in Ontario’s power system is expected to reduce GHG emissions. It found that “Distributed Generation CHP has the potential to reduce system-wide GHG emissions in the Ontario electricity sector.” However there are complicating factors. The analysis noted that Ontario is oversupplied in several respects until the early 2020’s and that “resources that are responsive to market signals are highly valued.” Distributed CHP will not likely reduce Ontario’s GHG emissions during surplus baseload generation events or periods of frequent oversupply.
The authors suggest that CHP installed today would not likely produce net emission reductions for the next 18 months, but would start to show significant emission reduction benefits after that point. The report says, “The average overall GHG benefits over the 20-year planning period is estimated to be a reduction of 0.06 tonnes/MWh under Outlook B to 0.16 tonnes/MWh under Outlook D for baseload CHP.”
The report is titled “Distributed generation combined heat and power GHG emissions impact analysis.”
