Natural Gas Demand Side Management (DSM)

Case number
Natural Gas

The Ontario Energy Board is committed to ensuring that natural gas customers have access to useful and appropriate programs that help them conserve energy and that benefit the natural gas system.

Enbridge Gas Distribution Inc. and Union Gas Limited have filed DSM plans with the OEB since 1995, which has included energy conservation programs available to the majority of their customers.

Most recently, the OEB developed a new DSM Framework and Guidelines to help the natural gas distributors form new multi-year DSM plans for 2015-2020. Both distributors applied for and received approval of new DSM plans based on the new Framework and Guidelines in early 2016.

OEB policy consultation to develop a new DSM Framework for 2021 and beyond.

Current DSM Framework and Guidelines governing 2015-2020 DSM programs:

The OEB completed its Mid-Term Review of the 2015-2020 DSM Framework on November 29, 2018. The Mid-Term Review included the OEB’s assessment of a number of studies and reports submitted by the natural gas utilities in response to requirements from the OEB’s 2015-2020 DSM Decision, a Stakeholder Conference, and consideration of various proposals and requests submitted by the natural gas utilities and other interested stakeholders.

The OEB’s DSM Mid-Term Review Report and the related documents filed as part of the consultation can be found on the OEB’s DSM Mid-Term Review webpage.

As outlined in the OEB’s Report on DSM issued December 22, 2014, the OEB will be taking a central role in the evaluation, measurement & verification (EM&V) of DSM program savings. DSM programs will be evaluated on an annual basis, with results issued by the OEB to be used by the gas utilities when they file applications for recovery of amounts related to DSM activities. 

DSM Evaluation information and related documents can be found on the OEB’s DSM Evaluation webpage.

The March 2014 DSM/CDM Directive to the OEB from the Minister of Energy requires that a conservation achievable potential study for natural gas efficiency in Ontario be conducted every three years, and coordinated with the Independent Electricity System Operator (IESO) as appropriate and reasonable.

Information on the OEB’s 2016 natural gas potential study and the OEB and IESO’s 2019 integrated electricity and natural gas potential study can be found on the OEB’s Natural Gas Conservation Potential Studies webpage.
