What is a Distributed Energy Resource (DER)?
Distributed Energy Resources (DERs) are electricity supply or demand resources that connect to the electricity grid. DERs can include solar installations, energy storage systems, electric vehicles, and other controllable loads in the residential, commercial and industrial sectors. There are a few options available to connect to the electricity grid, including Net Metering, Load Displacement and Backup Generation.
Net Metering enables Burlington Hydro customers who generate more power than they consume to receive credit on their electricity bill for all surplus power delivered to the grid.
For all generation projects, contact Burlington Hydro at
DER Application Process
Step 1 – Preliminary Consultation with Burlington Hydro (optional)
Prior to submitting an official application, the Applicant has the option to submit:
- DER – Pre Consultation Micro-Embedded Generation Form
- Permission to Release Account Information form (only required if the request is submitted by a third party).
The application gives Burlington Hydro some high-level details about the project and initiates a search for connection details and available capacity.
Burlington Hydro then responds to the Applicant via email. The Applicant can then review their options and decide if they would like to move forward with an official application for their DER project.
Step 2 – Connection Application
The Applicant must complete and submit:
- DER - Net Metering Connection Application - Form C
- Single Line Diagram
It is the Applicant’s responsibility to make sure the project adheres to the most current technical requirement documents available including:
- Burlington Hydro’s standards and specifications as provided in the Connection Proposal Package
- Technical requirements as listed in the Electrical Safety Authority Electrical Guidelines for Inverter-Based Micro-Generating Facilities (10kW and smaller)
- Burlington Hydro’s Conditions of Service
- Ontario Regulation 541/05 for Net Metering
Step 3 – Burlington Hydro Review and Connection Proposal Package
After reviewing the application, Burlington Hydro will confirm capacity for the requested project is a available and provide the Applicant with a Connection Proposal Package within 30 days that includes an Offer to Connect letter and outlines the requirements and construction costs to connect the generator.
Consult the Station Capacity Map to view areas in Burlington where there is restricted capacity for micro-generation. If there is no capacity available, Burlington Hydro will notify the Applicant and cancel the project.
Step 4 – Customer Acceptance of Project
As per the instructions listed in the Connection Proposal Package, the Applicant will then sign and return the
DER – Connection Agreement Micro-Embedded Generation Form, pay all necessary fees listed in the Offer to Connect letter, and complete a pre-construction meeting with a Burlington Hydro technician. Note that Burlington Hydro requires four weeks advance notice to book the pre-construction meeting.
Step 5 – Construction and Connection
At this stage the Applicant may proceed with construction as per the instructions in the Connection Proposal Package. The Applicant has 180 days from the date listed on the Offer to Connect letter to energize the project. When the project is ready to be energized, Burlington Hydro must be provided with:
- ESA Connection Authorization
- Signed Offer to Connect
- HST Form
- Payment
The Applicant must contact Burlington Hydro to schedule the installation of the new meter. Once the meter is installed, it is the responsibility of the owner to energize their equipment.
Step 6 – Account Maintenance and Ongoing Generation
Burlington Hydro’s Billing Department will process all account changes and begin issuing DER credits as applicable, beginning on the date the new bi-directional meter was installed provided that all required permits and commissioning has been completed.
It is important to note that it is the responsibility of the project owner to monitor the status of the generation project. Burlington Hydro is not responsible for reporting generation data or notifying the project owner if generation stops

The application could be rejected at any time if the Applicant does not meet the necessary requirements or deadlines.
Questions About Net Metering Accounts
How does my Net Metering account work?
The crediting system for Net Metering is solely based on generation versus consumption each month. The generated power is directly subtracted from consumed power on the statement - based on dollars. If the project generates more power than it consumes, a dollar credit bank is created and is carried over to the next month and so on for up to 12 months. Generally, projects generate more electricity than they use in the summer and use up the credit carried forward through the winter months.
Please note that income is never generated for DER accounts; if there is a credit surplus left over after the 12-month period, it is zeroed out.
These accounts have the option to choose from three RPP plans: Time-of-Use, Tiered, and Ultra-Low Overnight. For more information, visit our price plan page.
What requirements are there?
In order to activate a DER account, you must have an active load account with Burlington Hydro and your generation project must have a bi-directional meter installed. A bi-directional meter can only be installed after the DER application process is complete.
What about Harmonized Sales Tax (HST)?
As part of the process outlined above, you are required to provide an HST registration number, if applicable. If you do not have an HST registration number, please indicate this on the connection application form. Note that after your generation credits are subtracted from your monthly bill, any amount owing to Burlington Hydro each month will still have HST included in the final total.
If I move, who should I notify and what happens to my account?
If you should sell your property and leave the net metering project installed at the location, the generation credits will be issued to your account until your final date as the account holder for that address. At that point the account is zeroed out.
On the property transfer date (closing date) and moving forward, the generation credits will begin to be allotted to the new generation account for that address which is created by the new property owner. The new property owner will need to enter into a new Connection Agreement with Burlington Hydro.
How often will I receive an account statement?
Just as you did with your original Burlington Hydro account, you will receive a monthly statement.
