System Capacity Maps

• The CCIM is an online tool created by the OEB to give users a high-level view of 
  where available capacity exists on Ontario’s electricity distribution systems.
• The CCIM displays data about Ontario’s electrical grid capacity for both load and
  DER hosting connections to help support the delivery of affordable, secure reliable and clean energy that enables economic growth across the province.
• Data is provided by electricity distributors across Ontario and is updated at least 
  once every three months.
• The CCIM consists of two interactive environments:
  • Available Load Capacity: To provide awareness of potential connection points for additional load, such as housing, commercial or industrial sites.
  • Available DER Hosting Capacity: To provide awareness of potential connection points for small-scale power generating installations or energy sources.
• The CCIM is intended for preliminary screening only and does not replace any formal connection impact assessment process required by electricity distributors.

• The CCIM empowers consumers and developers with early visibility into grid 
  capacity, enabling faster site viability checks, informed comparisons, and smarter project decisions saving time, reducing uncertainty and accelerating energy 
  investments.
• The CCIM will help unlock the value of distributed energy resources, lower barriers 
  to participation and help enable smarter investments in our energy infrastructure.

EV and DER Providers / Developers

• The CCIM helps identify potential sites for EV charging stations and DERs, reducing 
  the number of preliminary information requests.
• It supports informed investment decisions by showing where the grid can 
  accommodate additional loads without system upgrades.
• The CCIM helps reduce barriers to deploying EV charging stations, especially when navigating multiple distributor service areas. 

Investors/ Commercial or Residential Developers

• The CCIM will help developers make faster, better informed siting decisions, enable targeted investments and help to drive economic development.
• Investors and developers can use the map to assess the potential connection 
  complexity for their energy projects, helping them to make informed decisions about 
  site selection.
• Consumers seeking to connect to the grid can use this map to:
  • Identify areas with available grid capacity for new businesses, housing 
    developments, and infrastructure projects
  • Compare locations to find the best sites for industrial expansion or renewable energy projects
  • Access consistent data that helps reduce uncertainty and accelerate project timelines
