IESO merger unifies Ontario's grid operations, electricity market oversight, long-term energy planning, procurement, and conservation, streamlining costs, enhancing reliability, and strengthening stakeholder engagement across the provincial power system, and improving efficiency and infrastructure.

 

What's Happening

The IESO merger integrates grid operations, oversight, planning, and conservation to enhance reliability and reduce costs.

  • Real-time grid and market operations under one operator
  • Long-term energy planning and procurement integrated
  • Enhanced conservation and demand management programs
  • Reduced overlap and administrative costs

 

The Independent Electricity System Operator IESO and the Ontario Power Authority OPA have now merged, operating as one organization.

 

This new organization is responsible for the real-time operation of the Ontario electricity system and market, long-term energy planning, procurement, and the promotion of a conservation culture in the province. Amalgamation will achieve efficiencies going forward by reducing overlap, reducing costs and streamlining electricity sector planning.

"The merger of the two organizations brings together a breadth of expertise and experience in the operation of and planning for the province's power system, as highlighted in the IESO's reliability outlook for Ontario," said Bruce Campbell, President and CEO of the IESO. "It deepens our role within the energy sector, allowing us to more effectively engage with stakeholders on key issues and, as noted in the IESO's positive 18-month outlook report outlining near-term expectations, develop new and more efficient approaches to meet the needs of all Ontarians."

The IESO is working to ensure the transition is as seamless as possible for customers and stakeholders. The IESO manages the province's power system so that Ontarians receive power when and where they need it. It plans and prepares for future electricity needs across the province, and works with its partners to guide conservation efforts.
