Transmission System PROJECTS
The transmission system is Ontario's electricity highway. Through it we send vast amounts of electricity from hydroelectric, wind, solar, nuclear and coal-burning generators over long distances to the local distribution companies (LDCs) that power Ontario homes and businesses. We continue to make investments to maintain and upgrade our system. We work with communities to ensure that our transmission system has sufficient capacity to deliver a safe and reliable supply of electricity.
While every project is unique, there are similarities in the planning process for new transmission system projects. Learn more about a project that is underway in your community by clicking on the project below.
