What's New

Today, the Ontario Energy Board (OEB) issued a revised Handbook to Electricity Distributor and Transmitter Consolidations: Rate-making Considerations and Filing Requirements for Consolidation Applications (2024 MAADs Handbook, originally published June 18, 2024). 

In addition to correcting a few minor typographical errors, the revised 2024 MAADs Handbook also clarifies that a distributor rebasing in a period of 5 years or less (and not just less than 5 years) is required to provide a report on the rebasing progress at its first rebasing application post-consolidation.

The Province of Ontario has appointed Mark E. White as Chair of the OEB’s Board of Directors. Mr. White is an accomplished leader in regulation, policy and governance. He brings a strong background in law, risk management, markets and organizational transformation, having served as the inaugural Chief Executive Officer of Ontario’s Financial Services Regulatory Authority.  Geoff Owen, an OEB Director since September 2021 and Chair of the Board of Directors’ Letter of Direction Task Force, has been appointed as Vice Chair of the Board of Directors. With Mr. White and Mr. Owen, the Board of Directors will continue its work to support the OEB through the energy transition, strengthen public trust and provide strong leadership and good governance.

The OEB has launched the Vulnerability Assessment and System Hardening (VASH) project in relation to the OEB’s Distribution Sector Resiliency, Responsiveness and Cost Efficiency initiative. The VASH project has been initiated to address the ask from the Minister of Energy (now Energy and Electrification) to develop and implement policies to improve distribution sector resiliency in response to the challenges posed by climate change.
