Information Regarding Generation Facilities Interconnection to NT Power

One of the goals of the Provincial Government is to create more opportunities and encourage the connection of small generation facilities to the electrical distribution grid. As a result, under the direction of the Ministry of Energy, two programs are being offered to any Ontario electricity consumer who can generate electricity from renewable resources:

These programs allow customers to generate some or all of their electric load requirements (referred to as load displacement), and also export the excess power onto the local distribution electrical grid (referred to as an embedded generator). The process is governed by regulated financial settlements with the Local Distribution Company (LDC) in accordance with the Retail Settlement Code (RSC).

What do you need to know about embedded generation? Embedded generation is considered any generation facility which is not directly connected to the transmission grid, but instead is connected to a distribution system. (i.e., NT Power.)

NT Power supports the incorporation of embedded generation facilities within the electrical distribution system. The process is guided by the latest revision of the Distribution System Code (DSC) issued by the Ontario Energy Board. The Code sets out the minimum obligations that a licensed electricity distributor (such as a LDC) must meet in carrying out its obligations. The latest revision of the Code can be found on the official website of the OEB under Industry Relations/Rules, Codes, Guidelines and Codes.

Generators of electricity are divided into different sizes in accordance with the DSC.

DER Classification Rating

≤ 10 kW


Small (a) ≤ 500 kW connected on distribution system voltage < 15 kV
(b) ≤ 1 MW connected on distribution system voltage ≥ 15 kV
Mid-Sized (a) ≤10 MW but > 500 kW connected on distribution system voltage < 15 kV
(b) > 1 MW but ≤ 10 MW connected on distribution system voltage ≥ 15 kV

> 10 MW


NT Power will apply its Conditions of Service for any generation interconnection costs and/or any metering changes that NT Power deems necessary to allow for settlement purposes.
