Conservation Fund Overview

Changes to the IESO Conservation Fund’s Application Intake Process

The IESO Conservation Fund has supported over 200 innovative Conservation and Demand Management projects since the fund’s establishment in 2005, shaping the incentive programs, training options, tools, and products available to Ontario customers today. In 2016, the IESO commissioned a strategy report to understand how to maximize the impact of the fund in light of the significant changes to the electricity system and wider energy industry during the previous decade. The report was developed with input from more than forty stakeholders.

As a result of the strategy recommendations, IESO will be making changes to the fund’s application intake process. Effective March 1, 2018, the Conservation Fund will no longer accept unsolicited applications on a continuous basis and move to set time windows for accepting unsolicited applications. The next open intake window for unsolicited applications to the Conservation Fund will be from July 1 to 31, 2018.

Additionally, the IESO will increase the frequency of targeted calls for project proposals addressing specific identified challenges and opportunities. These calls for project proposals will be communicated on the Conservation Fund webpage, via the IESO Bulletin and LDC E-Blast, and through other channels. More information on targeted calls and the schedule of application windows for unsolicited applications will be forthcoming.

The Conservation Fund supports innovative conservation technologies, practices, research and programs that have the potential to deliver significant energy savings. Since 2005, the Conservation Fund has provided financial support for more than 200 innovative energy projects across Ontario.

The Fund seeks projects that will lead to large-scale transformation in the marketplace or a change in consumer behaviour; projects that demonstrate the energy saving potential of emerging technologies and investigate novel conservation concepts.
