Types of DERs

Types of DERs 

We frequently see people use their distributed energy resources as emergency back-up generators or to join our net metering, non-exporting or stand-alone generation programs.

Emergency back-up generators

Only use a generator when you can’t access the local grid, like during a prolonged power outage. It will keep you connected when it matters most. You’ll find a variety of generators on the market, so we encourage you to do your research before you buy. For more information, check out our blog.

To learn how to connect your generator, refer to our standard ECG0002 Technical Guideline For Customer Owned Standby Generation.

If your generator can send electricity to the grid, it has to meet the requirements listed in ECG0006: Distributed Energy Resource Technical Requirement.

Net metering programs

Our net metering program allows you to generate and use your own electricity. As a net metering customer, you’ll rely less on our supply, which means you’ll save more on your bill. What’s more, you’ll have the option to send energy to the grid for a non-cash credit. To view a net metering bill, click here.

To qualify for our net metering program, you have to use a Renewable Energy Technology (RET) to generate power. RETs produce electricity from clean sources, including water, solar and agricultural biomass. Please note: You can pair an RET with an energy storage system to form a net-metering installation as energy storage systems are considered sources that generate electricity when discharging. But an energy storage system alone does not qualify for the net-metering program.

Program requirements:

  • The energy source must be renewable as defined in our Conditions of Service.
  • The grid must have capacity for your RET. 
  • Your project must pass our assessment and approvals.
  • Your project must pass the Ontario Electrical Safety Authority’s requirements.

Non-exporting generation

If you’d prefer to generate electricity exclusively for your own use, you can join our non-exporting generation program. As a member of this program, you’ll still save money on your bill, but you won’t receive any credits. 

Please note: You’ll need revenue grade metering to measure your non-exporting DER’s production if its capacity meets or exceeds 500 kilowatts (kW).

Requirements:

  • Any energy source may be used.
  • The grid must have capacity for your DER.
  • Your project must pass our assessment and approvals.
  • Your project must pass the Ontario Electrical Safety Authority’s requirements.

Stand-alone generation

If you’d like to send all of the electricity you produce to the grid, you can join our stand-alone generation program. As a member of this program, you’ll receive compensation for every kW that you send to us. Please note: To become a stand-alone generation customer, you’ll need a dedicated electrical service. That means you’ll have to meet additional requirements for your metering, monitoring, control and protection. 

Requirements:

  • Any energy source may be used
  • The grid must have capacity for your DER.
  • Your project must pass our assessment and approvals.
  • You must get a generator license from the OEB. 
  • In some cases, you may need a contract with the Independent Electricity System Operator (IESO)
  • Your project must pass the Ontario Electrical Safety Authority’s requirements.
  • You must register for an HST account.
  • Your project must pass the City of Ottawa’s requirements (zoning, building, by-law, etc.).

Please note: We’ve only listed our conditions on this page, but you’ll work with other agencies during the connection process, and you should understand and comply with their requirements, too. You’ll find most of these organizations in our references. 

If you have permanently connected DER equipment, such as an emergency back-up generator, you’ll have to write to us and list the equipment’s intended use, location and nameplate capacity output. For more information, refer to ECG0006: Distributed Energy Resource Technical Requirements.
