Connecting to the Grid
MicroFIT - EnWin Requirements
There are a number of requirements that must be fulfilled before EnWin Utilities is able to connect your project. Please be sure to follow the steps outlined in the mFIT Connection Guide.
Applications must be made using Enwin's online form which can be accessed by clicking the link entitled "EG Application Form" below.

Net Metering - EnWin Requirements
As a means to encourage conservation, EnWin Utilities Ltd. has established a program for eligible customers wishing to participate in Net Metering. This program is in compliance with Ontario Regulation 541/05 - Net Metering.
Net Metering is a program whereby eligible customers with specific generation facilities can reduce their net energy costs by exporting surplus generated energy back onto the utility distribution system for credit against the energy the customer consumes from the distribution system.
Participation in the Net Metering Program is available to all EnWin Utilities customers with a generator that meets all of the following conditions:
- The electricity is generated primarily for the customer's own use;
- The electricity generated is conveyed to the customer's own consumption point without reliance on the EnWin Utilities distribution system;
- The maximum cumulative output capacity of the generator does not exceed 500 kW;
- The electricity is solely generated from a renewable energy source (such as wind, drop in water elevation, solar radiation, agricultural bio-mass, or any combination thereof).
Note: As is also the case for microFIT and FIT generation, the customer must install an isolation device satisfying Section 84 of the Ontario Electrical Safety Code, located outside typically near the meter, and agree to the utility's staff access to and operation of this as required for the maintenance and repair of the distribution system.
In order to participate in the Net Metering program, the customer will be required to meet all the parallel generation requirements for Connecting Micro-Generation Facilities (10 kW or less) or Other Generation Facilities (greater than 10 kW and up to 500 kW), as applicable to the generator size. Please see our Net Metering Requirements Letters below for further details.
Customer and Transformer Station Relationship
Use the Customer Transformer Station PDF map to determine the transformer station supplying a specific customer site. Use this map in conjunction with the Hydro One Station & Feeder Capacity Calculator (below) to determine if there is capacity in the grid to accomodate your project.
Hydro One Station & Feeder Capacity Calculator
Use the Hydro One Station & Feeder Capacity Calculator to determine if there is capacity to connect a project at a particular Station/Feeder. Follow the instructions at the link below. Feel free to contact EnWin Utilities to confirm capacity for a specific location.
