Targeted Call for Proposals

Indoor Agricultural Call

With more than 1,300 MW of greenhouse load seeking to connect in Ontario by 2025, the province’s electrical infrastructure is being challenged to meet significant increases in the demand for power. Through its Grid Innovation Fund, the IESO is issuing a call for novel projects focused on reducing electricity demand from indoor agriculture during local and bulk system peak periods. The IESO will accept proposals from November 18, 2019 – February 14, 2020 and award up to $2.5 million for approved projects. Special consideration will be made for projects located in areas with identified or anticipated electricity infrastructure challenges related to indoor agriculture expansion.

Call for proposals - 2019

At a high level, this targeted call aims to:

  • Accelerate the adoption of cost-effective demand-side solutions by greenhouse growers
  • Demonstrate the efficacy of demand-side options to address local transmission and distribution infrastructure capacity need(s)
  • Explore unknowns in the operationalization of demand-side options and the impact on greenhouse productivity

Please refer to the Grid Innovation Fund Indoor Agriculture Call Application Guideline for full eligibility criteria. Applicants are strongly encouraged to carefully review the Guideline before drafting and submitting a proposal.


Proposal Submission


The Grid Innovation Fund Agriculture Call Proposal intake window is now closed. Proponents will be contacted in 6-8 weeks with an update on their submission.
