Industrial Conservation Initiative (ICI)

Class A Methodology for Billing the Global Adjustment
Hydro One on a site visit with an industrial customer  

The Industrial Conservation Initiative (ICI) is a demand-response program aimed at shifting large electricity users’ consumption to off-peak hours, when the Ontario system is at its highest demand. It allows these customers to manage their Global Adjustment (GA) costs by reducing demand during peak periods.

Please review our 2023 ICI Presentation and updated FAQs below to learn more about the program, including information on the recent regulatory amendments to O. Reg. 429/04 (Adjustments under Section 25.33 of the Act) under the Electricity Act, 1998 (GA Regulation).

To support the education and decision-making process for ICI,
please review our updated 2023 ICI Presentation below:

Information contained in the videos below is in reference to the 2021-2022 adjustment period. Updated information will be published in May 2022.

Which customers are eligible for Class A?

Customers who meet the monthly peak demand eligibility, will be notified and provided with their Peak Demand Factor and a Class A vs B comparison using their historical data by end of May. A link to our online Opt in/Opt out form will be provided in the communication mentioned above.

  • Customers who fall within the >500kW <1000kW usage threshold will be required to declare the NAICS code that best represents their service/facility.

  • Customers who fall within the >1000kW <4999kW usage threshold can opt in without NAICS code restrictions.

  • Customers with an average peak demand greater than 5000kW are automatically included in the program and have the option to opt-out of the ICI.

How do you Opt In or Opt Out?

Class A eligibility and instructions are communicated via email each May. The deadline to communicate this information is May 31st.

Important Items for Consideration:

  • Reminder: you will be billed on your assessed PDF for the entirety of the adjustment period July 1 – June 30

  • Are you expecting your load requirements to decline over the adjustment period? For example:

    • as a result of implementing efficiency measures at the facilities,

    • parceling off a section of the facility for an alternate entity or,

    • an expected general decline in business activities at the location.

How can system peaks be forecasted?

How do I transfer my Class A load facility?
