Energy Efficiency Research
A deep understanding of emerging issues in Ontario is crucial to electricity planning. The IESO undertakes in-depth research and energy profiles to determine the scope of issues, and identify greater opportunities for energy efficiency within industries, municipalities and communities.
Mid-tier commercial real estate energy study
The IESO commissioned a mid-tier commercial real estate (CRE) energy study in Ontario to assess energy management behaviours and perceptions, and to inform engagement with building owners and managers. The study provides valuable insights for industry stakeholders to help understand mid-tier operators’ drivers, barriers, decision making process, knowledge of and participation in energy efficiency and what is needed to help improve the overall operations of their buildings. Read the study.
Exploring energy-efficiency solutions in greenhouses
Ontario’s greenhouse electricity use is forecast to increase 180% to 3.9 TWh by 2024, driven by rapid expansion in the province’s prime growing regions and dependence on grow lighting. Commissioned by the IESO, in partnership with Enbridge Gas and the Ontario Greenhouse Vegetable Growers, this Save on Energy’s Retrofit program – in addressing growing demand.

Strengthening communities through energy efficiency
What are some of the most innovative strategies municipalities can adopt to save energy and money? The Ontario Municipal Energy Profile report looks at why energy efficiency is a game-changer for municipalities, and how NextGen technologies such as net-zero buildings and net-zero or energy-plus wastewater treatment plants can make a difference for the future. Read the summary.
Pumping out energy savings at municipal water treatment plants
Water and wastewater treatment accounts for over a third of municipal energy consumption, which means energy savings here can really have an impact. Market Characterization and Conservation Potential for Ontario's Drinking Water and Wastewater Treatment Plants highlights the tremendous potential for energy efficiency solutions in the water and wastewater treatment sector. Read the summary.
Home Energy Survey
In the summer of 2018, the IESO conducted its first ever comprehensive Residential End Use Survey (REUS). The REUS provides valuable information about the building characteristics, equipment, appliances and behaviours that drive residential energy use in Ontario. The REUS provides important information to the IESO, local distribution companies (LDCs), gas utilities and other stakeholders to support three primary objectives:
- Develop end-use saturations and fuel shares to support the 2019 achievable potential study;
- Provide data on residential building characteristics, equipment penetration and demographics to support program design, evaluation and marketing.
- Provide relevant household equipment data to support electricity load forecasting.
Detailed REUS results can be found in the Dynamic Reporting Tool, which is available upon request. This tool summarizes the REUS results and allows users to query data for specific regions, housing types, etc.
For more information about the REUS and/or for a copy of the Dynamic Reporting Tool, please email email@example.com. Your email should include a link to this web page and should advise whether the tool needs need to be provided in an accessible format. Please allow a minimum of one business day for a response. Once you have received this tool, please review the “Read Me” tab for instructions on how to use it.
