The Ontario Energy Board (OEB) is pleased to present our 2025/26 to 2027/28 Business Plan (the Plan), which focuses on fiscal year 2025/26 and includes forward-looking preliminary budgets for 2026/27 and 2027/28.

The demand for clean, affordable and reliable energy is increasing rapidly. Ontario is advancing a competitive all-of-the-above approach to meet this challenge, including using nuclear, hydroelectricity, natural gas, wind, solar and other sources to meet growing energy demands while emphasizing the province’s energy transformation and electrification goals.

The OEB’s role in the energy sector has never been more important. Although change is happening, in the sector and within the OEB, we are focused and ready to deliver on our mandate.  

This Plan lays out our near-term response: to provide strategic and prudent oversight of Ontario’s energy sector through initiatives that support broader government priorities such as planning for growth, keeping costs down, enabling energy system modernization and streamlining solutions that will make Ontario an energy superpower.  

Our work plan is informed by the Ministry of Energy and Mines’ (the Ministry) 2024 vision statement, Ontario’s Affordable Energy Future: The Pressing Case for More Power (the Government’s vision), which identifies energy priorities and provides policy guidance to the OEB on how to act within its legislated authorities. The OEB will support delivery of this vision by performing its adjudicative and other regulatory functions impartially, efficiently and transparently.
