Centralized Capacity Information Map
Every day, Ontario’s electricity grid keeps millions of homes and businesses running. As new neighbourhoods emerge, businesses expand, and more clean energy facilities come online, the demand for reliable, affordable, and secure electricity continues to grow.
To support this growth and enable smarter planning, the Ontario Energy Board has launched the Centralized Capacity Information Map (CCIM) – a powerful tool designed to provide transparent, accessible data about the province’s electrical grid capacity for both load and Distributed Energy Resource connections.
For optimal viewing, please access the CCIM on a desktop or laptop in full-screen mode.
