For distribution facilities operating at voltages of 50 kV or less.

We connect generating facilities to the distribution system, delivering the electricity they produce at hydroelectric, wind and other facilities to businesses and people across Ontario. We work with these customers to plan for the future and make sure facilities are in place to deliver electricity where it needs to be.

Visit the Independent Electricity System Operator's website for more information about the benefits and incentives available for connecting your renewable energy project to our distribution system. Learn more about Hydro One's Net Metering program.
