Conservation and Demand Management
The Ontario government launched the 2021-2024 CDM Framework on January 1, 2021. The framework focuses on cost-effectively meeting the needs of Ontario’s electricity system, including by focusing on the achievement of provincial peak demand reductions, as well as on targeted approaches to address regional and/or local electricity system needs.
CDM programs are delivered by the Independent Electricity System Operator (IESO) through the Save on Energy brand. These programs address electricity system needs and help consumers reduce their electricity consumption to lower their bills. CDM programs and incentives are available for homeowners, small businesses, large businesses, and contractors, and First Nations communities.
New and Expanded Programs
The four new and expanded CDM programs will include:
A new Residential Demand Response Program for homes with existing central air conditioning and smart thermostats to help deliver peak demand reductions. Households who meet the criteria could voluntarily enroll in this program to be paid an incentive in return for the IESO being able to reduce their cooling load on a select number of summer afternoons to reduce peak demand. There are an estimated 600,000 smart thermostats installed in Ontario.
Targeted support for greenhouses in Southwest Ontario, including incentives to install LED lighting, non-lighting measures or behind-the-meter distributed energy resources (DER), such as combined solar generation and battery storage.
Enhancements to the Save On Energy Retrofit Program for business, municipalities, institutional and industrial consumers to include custom energy-efficiency projects. Examples of potential projects could include chiller and other HVAC upgrades for a local arena, building automation and air handling systems for a hospital, or building envelope upgrades for a local business.
Enhancements to the Local Initiatives Program to reduce barriers to participation and to add flexibility for incentives for DER solutions.
It is the government’s intention that the new and expanded CDM programs will be available to eligible electricity customers beginning in Spring 2023.
The IESO estimates that the new program offers will deliver total provincial peak electricity demand savings of 285 megawatts (MW) and annual energy savings of 1.1 terawatt hours (TWh) by 2025. Savings will persist beyond 2025 with a total reduction in system costs by approximately $650 million over the lifetime of the measures, and will support economic recovery, decarbonization and energy cost management for homes and businesses.
These enhancements will have a particular impact in Southwest Ontario, with regional peak demand savings of 225 MW, helping to alleviate electricity system constraints in the region and foster economic development.
The overall savings from this CDM programming will result in an estimated three million tonnes of greenhouse gas emissions reductions over the lifetime of the energy-efficiency measures to help achieve Ontario’s climate targets and protect the environment for the future.
The IESO will be updating the CDM Framework Program Plan, which provides a detailed breakdown of program budgets and energy savings and peak demand targets expected to be achieved.
