Regulatory Documents

As a Local Distribution Company, NT Power is regulated by the Ontario Energy Board (OEB) a crown corporation that is responsible for overseeing the province’s electricity and natural gas sectors and all of its participants. NT Power's rate applications must be approved through a complex hearing process from the OEB. The OEB also sets the prices for Regulated Price Plan time-of-use electricity rates and approves the rates for distribution/delivery and transmission. In short, they are the regulatory policy makers, and it is our job to inform you on our regulatory activities.
