Combined Energy Options Ontario Working Group

Past Chair: Dr. Christine Koenig 

This working group works on long-term energy planning matters. In the spring of 2016, the working group developed a survey for the OSEA membership to rank strategic priorities, defining the scope of Ontario's next long-term energy plan. View the Report on OSEA's LTEP 2016 Membership Survey.

The working groups major initiative is the Combined Energy Options Ontario (CEOO) Study. A study that aims to model the transition to a low-carbon, decentralize, integrated and inclusive energy system. 

Combined Energy Options Ontario will provide a model/tool for evidence-based decision-making in the pursuit to develop a low-carbon, decentralized, combined, affordable and sustainable energy system in Ontario.

The Mission of the CEOO Study is to:

- proactively engage in Ontario’s long-term energy planning process and to steer it into the direction of a comprehensive energy systems plan, including heating, cooling, transportation, and electrical energy infrastructure and systems.

- conduct a comprehensive feasibility study on, and develop a simulation and model of a future 100% sustainable energy system to support this process and OSEA’s mission.

Objectives of Combined Energy Options Ontario

Conduct a comprehensive study into Ontario’s sustainable energy resources and today’s energy systems, and based thereon develop a simulation and model for a future

100% sustainable – low carbon, combined energy system

The study, and its results, documentation, and models will:

      • help us understand how and when such an energy system can be realized and under what circumstances it will become feasible,
      • investigate the economic, environmental and societal opportunities,
      • identify the technological and political barriers to implementation,
      • lend itself to public communication and education of our politicians and public officials about the chances and opportunities of such an energy future.
