IESO and the Ontario Energy Board have added three new members to their governing bodies — including two Indigenous women mayors.

The Ontario government’s efforts to align IESO and the Ontario Energy Board to make the province an energy “superpower” was the dominant theme at the 2025 Ontario Energy Conference.

The Ontario Energy Board's new CEO insisted it will retain its independence in adjudications even as it embraces the province’s directive to consider economic development in its policymaking.

The Ontario government’s ambitious energy plan could prove costly to ratepayers if load growth stalls or new nuclear plants produce cost overruns, said A.J. Goulding, president of London Economics International.

Ontario’s energy regulator is learning new ways to identify inefficiencies and malign behavior under IESO’s Market Renewal Program.

Ontario’s Progressive Conservative government continues to put its stamp on the province’s energy policy, proposing legislation that would add “economic growth” to the missions of IESO and the Ontario Energy Board.

The Ontario Energy Board plans a 22% increase in its 2025/26 budget with the addition of 32 employees, its biggest hiring surge in at least five years.

Ontario is putting its chips on nuclear power and natural gas to meet its growing energy demand while directing IESO to incorporate gas distributors and the province’s economic development goals in its system planning.

Ontario’s newly released integrated energy plan includes a long "to do" list for grid operator IESO.

IESO is scheduled to launch its new nodal market May 1, a change it says will save Ontario $700 million over the next decade through reduced out-of-market payments and increased efficiency.
