Ontario Combined Heat and Power Consortium

Working Group

Follow QUEST on

The Ontario Combined Heat & Power (CHP) Consortium works to broaden the debate around and deepen understanding of combined heat and power.

Working Group Participants

Representatives from industry, LDC’s, gas utilities, the public institutional sector, and technology & service providers lead the Consortium. Participation is exclusive to QUEST Supporters.




CHP can support Government policy objectives of improved resiliency, a vibrant economy, job creation, and a sustainable energy system.


CHP systems improve power system reliability and the ability to provide locally generated electricity.


CHP is a mechanism to help manufacturing and production facilities in Ontario manage their competitive advantage, carbon footprint, energy costs & consumption, and job creation.

Power Advisory’s marginal emission factors estimates can maximize GHG emissions reductions for Ontario’s electricity sector

A recent report developed by Power Advisory LLC recommends using its estimates of marginal emission factors to devise an optimal strategy for reducing greenhouse gas (GHG) emission in Ontario’s electricity sector.

The report provides an overview of Power Advisory’s methodology, its marginal emissions factor estimates, and guidelines for their use in assessing greenhouse gas emissions impact of future programs, policies, and technologies.

Globally, there is a growing consensus on the need for the reduction of greenhouse gas (GHG) emissions to combat the negative impacts of climate change. Currently, both average emission factors (AEFs) and marginal emission factors (MEFs) are used to evaluate the greenhouse gas emissions impact of policies and programs. To accurately assess the net greenhouse gas emissions impact of activities in the electricity sector in Ontario, it is critical to select the appropriate type of emission factors that capture the relationship between fuel consumption, electricity generation and consumption on an hourly, daily and seasonal basis. MEFs are well suited for this purpose as they take into consideration the seasonal and time-of-use factors.

However, using current or historic MEFs does not adequately reflect the future impact of activities. For example, Ontario’s MEFs are expected to increase significantly when the Pickering nuclear station retires at the end of 2025. When assessing future policies and programs, it is important to use MEFs forecasts that incorporate the expected changes in Ontario’s electricity system (e.g. changes in supply mix and demand).

Power Advisory’s MEFs can effectively assist stakeholders in determining the optimal strategy to reduce GHG emissions as they account for emissions from both gas-fired generation located in Ontario and imports from neighboring jurisdictions, including how these inputs will change over time due to nuclear refurbishments and the shutting down of Pickering nuclear station.

The accuracy of Power Advisory’s MEFs can be observed from a case study performed to evaluate the GHG emissions savings for installing a CHP system at a multi-unit residential building using hourly MEFs calculated by Power Advisory. In the case study, MEFs were used for 6 CHP sizes and configurations ranging from 24 kW to 175 kW and the analysis confirmed that CHP reduced net GHG emissions in each scenario as compared to emissions from displaced grid electricity and an on-site boiler. With the use of other emissions factors that do not consider future changes in electricity grid emissions, the outcome would have been different.
