Energy Evolution: Ottawa’s Community Energy Transition Strategy

Energy Evolution is the action plan for how Ottawa will meet the targets to reduce greenhouse gas (GHG) emissions from the community by 100 per cent by 2050 and from City operations by 100 per cent by 2040. Its vision is to transform Ottawa into a thriving city powered by clean, renewable energy.

Realizing Energy Evolution’s vision will require concerted efforts and collaboration across all sectors of the community. The strategy is guided by three components:

  • Reduce energy use through conservation and efficiency
  • Increase the supply of renewable energy through local and regional production
  • Prioritize the procurement of clean, renewable energy

Pathways and Energy and Emissions Model

Fourteen technical pathways documents have been developed that examine different technologies that can help achieve the GHG emission reduction targets. The pathways focused on renewable energy, buildings (new and existing), transportation, waste and wastewater, and energy storage and demand management and considered opportunities and constraints that could influence uptake.

This study is available in English only and may be translated in whole or in part upon request. For more information, please contact Emma Langham at 613‑580‑2424, extension 13858.

The results of the pathways were integrated into an energy and emissions model. The model presents two different future GHG emission scenarios compared to a 2016 baseline year:

  • Business as planned – illustrates Ottawa’s future greenhouse gas emissions based on all current policies, actions and strategies to address energy and emissions.
  • 100 per cent GHG emissions target – explores the scope and scale of change required for Ottawa to reduce GHG emissions 100 per cent below 2012 levels by 2050

Modelling results are broken down into five key sectors:

  • Land Use and Growth Management
  • Buildings (New and Existing)
  • Transportation
  • Waste and Renewable Natural Gas
  • Electricity

The table below summarizes where community wide GHG emission reductions are modelled to come from between now and 2050 in the 100 per cent GHG emissions target scenario.

Sector Percentage of total projected GHG emissions reductions
Year 2030
Land Use and Growth Management Imbedded in other actions
Buildings (New and Existing) 39
Transportation 28
Waste and Renewable Natural Gas 25
Electricity  7
Total 100
Sector Percentage of total projected GHG emissions reductions
Year 2050
Land Use and Growth Management Imbedded in other actions
Buildings (New and Existing) 37
Transportation 37
Waste and Renewable Natural Gas 17
Electricity 9
Total 100

Details on the 44 model actions and their relative GHG emissions reductions are included in the document Modelling Ottawa’s Greenhouse Gas Emissions to 2050: Summary of Results

It should be noted that the model is still in draft format and is subject to change as it’s updated to align with the new Official Plan.

Reporting

Council received a status update in January 2020. The final report for Energy Evolution is expected in 2020. This report will include:

  • Final energy and emissions model
  • Financial and affordability analysis of the model
  • Descriptions of the proposed projects
  • An action plan
  • Proposed spending plan for the 2019 Hydro Ottawa dividend surplus

Community Led Projects

To support community action the City invested $800,000 over two years in community-led projects that directly supported the vision of Energy Evolution through the Energy Evolution Catalyst Project and the Community Energy Innovation Fund.
