Renewable Generation

Notice to Generation Applicants

Customers interested in connecting distributed energy resources (DER) such as renewable generation to the distribution system are encouraged to review the Net Metering program requirements contained in our  Connected Distributed Energy Resources guide and contact our Engineering Department at 519-853-3700 Ext. 213 or

Generation Connected in Halton Hills: 5648kW as of May 2019.

Connection of Distributed Energy Resources

Halton Hills Hydro is accepting connection requests from customers interested in installing a Distributed Energy Resource at their facility. What are Distributed Energy Resources?
Some examples are:

  • wind turbines
  • roof-top or ground mounted solar PV panels/ arrays
  • waterpower project situated on a watercourse and waterfall
  • a generator fueled by biomass on a farm
  • battery storage system
  • combination of any of these technologies and other technologies that generate power

Process for Connection, Connecting Distributed Energy Resources, & Applications Forms

The process for connecting a distributed energy resource project to the distribution system is outlined “Connecting Distributed Energy Resources” guide. We encourage any customers interested in connecting a distributed energy resource to review these guidelines and contact our Engineering Department to discuss your project.

Customers requesting a pre-consultation with Halton Hills Hydro about their project can complete our DER Preliminary Consultation Application form (Appendix 2) in our guide. Submit this form to

Important Notice regarding In-Series Connection Requests

On April 9, 2010, the Independent Electricity System Operator (“IESO”) informed distributors that Measurement Canada had indicated that it “will not recognize or support” the in-series metering configuration as described in the IESO’s MicroFIT rules. Measurement Canada’s concerns would also apply to contracts under the FIT program. The IESO’s discussions with Measurement Canada have not resulted in a resolution to this matter. Given that distributors must comply with Measurement Canada’s laws, regulations and requirements regarding metering, and given Measurement Canada’s current assessment that it will not support in series configurations, the Ontario Energy Board has determined that distributors shall not connect any indirect in series configurations to their distribution system under the MicroFIT or FIT programs. The IESO has also reflected this on their website.

Important Notice regarding Constrained microFIT Applications (IESO)

On April 5, 2012 the Independent Electricity System Operator (“IESO”) informed distributors of relocation options for microFIT applicants who had submitted an application to the IESO before December 8, 2010 and received a Conditional Offer that had not expired as of August 19, 2011. These applicants would have also requested an Offer to Connect form their LDC but were informed by their LDC that connection capacity was not available. Please see the following link for information from the IESO.
