The Ontario Power Authority develops integrated electricity plans that look forward several years, with the purpose of providing sustainable electricity solutions to Ontarians well into the future. 

The plans take a long-term, province-wide perspective, examining possibilities for future electricity demand and how it can be met through conservation, generation and transmission options. The aim is to enable the electricity system to meet technical standards and public policy objectives in ways that are acceptable to the community. 

These plans form the technical basis of the advice the OPA provides to government to inform policy priorities, including:  

  • making Ontario efficient in its use of electricity; 
  • phasing out the use of coal;
  • increasing renewable energy sources; and, 
  • deploying information and technology to improve customer service. 

Implementation happens through generation procurement and conservation measures, and by developing transmission.

The OPA also initiates and participates in regional planning projects, recognizing that different areas of the province face unique circumstances that require local analysis and engagement.

The OPA regularly produces reports, regulatory submissions and presentations on electricity planning. These materials outline the status and outlook of the electricity system, identify challenges to be addressed, and presents options and opportunities to address them. They are made public through regulatory forums, presentations at conferences and stakeholder engagement sessions. 

In 2005, the OPA developed strategic advice on the supply mix for Ontario, and in 2007 produced a detailed Integrated Power System Plan (IPSP I) to implement the supply mix. Initiatives from the 2007 plan, together with subsequent public policy initiatives (primarily the Green Energy and Green Economy Act) are transforming how Ontario produces and uses electricity.
