Large building owners are required to report their energy, water and greenhouse gas emissions to the Ministry of Energy, Northern Development and Mines on an annual basis under the Energy and Water Reporting and Benchmarking (EWRB) regulation.

The EWRB is designed to improve energy and water efficiency in large, privately-owned buildings. This regulation applies to privately-owned buildings that are 50,000 square feet or larger, including commercial buildings, multi-unit residential buildings (with more than 10 units), and some industrial buildings. 

When Do I Need To Report?

If you own a building that is 50,000 square feet or larger, you may need to report your building’s annual consumption to the Ministry of Energy, Northern Development and Mines by July 1 each year.

Please note, you’re reporting on the previous year’s consumption (so your July 1, 2025 submission will be based on 2024 consumption data).

How Do I Request My Data?

Please note, water consumption information will be provided by the City of Waterloo, the City of Kitchener, the Township of Wilmot, the Township of Woolwich, or the Region of Waterloo, depending on your property’s location.

Please submit your request(s) for information as soon as possible. Requests can take up to four weeks to process. 

Follow these steps to request your electricity data:

1. Complete and submit our online form.
2. Review Process:
   If we need more information, one of our representatives will contact you to obtain the information needed to complete your request.
3. Data Submission
   Once we have received, reviewed and verified your information, we will process your request and send you the yearly aggregated electricity consumption data for your property as quickly as possible.

 *The EWRB Request Form is also available as a PDF if required. Please email us to request a PDF version of the form.

What Do I Need To Begin My Application?

Before you start your application, we will need:

1. At least one account number for each address that is part of the property.
2. The electronic bill verification code from your most recent bill.
3. The service address for the property you are requesting data for.
4. The EWRB Number provided to you by the Ministry of Energy for the property. If you do not have an EWRB number, you can get one from the Ministry of Energy by emailing EWRBSupport@ontario.ca or calling 1-844-274-0689.
5. Square footage information for the property

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. This allows customers to manage their Global Adjustment by reducing demand during on-peak hours.

Customers who participate in the ICI, referred to as Class A, pay Global Adjustment based on their percentage contribution to the top-five peak Ontario demand hours over a 12-month period.

Who is Eligible?

Customers who are eligible to participate in the ICI include:

• Customers in the manufacturing sector, as well as greenhouse, nursery and floriculture production facilities with an average monthly peak demand of greater than 500 kW and less/equal to 1 MW are eligible to opt-in to the ICI if their establishment NAICS codes start with the digits “31,” “32,” “33,” or “114.”
• All customers with an average peak demand of more than 1 MW, up to and including 5 MW are eligible to opt-in to the ICI.
• Consumers with an average peak demand greater than 5 MW are automatically included in the program and have the option to opt-out of the ICI.
• Existing Class A customers who participated in one or more of the programs specified in  429/04and dropped below the peak demand threshold during a base period for an adjustment period that began on or after July 1, 2016, may be eligible to opt back into the initiative.

Customers with an average peak demand greater than 5 MW are automatically included in the program and have the option to opt-out of the ICI. Separate load facilities cannot be aggregated in order for a customer to qualify as Class A (even if they are under the same ownership). The Ministry of Energy requires Class A-enrolled customers to provide the address and GPS Coordinates of their head office and enrolled load facilities, as well as consent for the information to be shared with the Ministry and made public.

Timing

Each cycle of the ICI starts with a base period from May 1 – April 30. At the end of this period customers are assessed for eligibility.

Do I Qualify for the ICI?

If you are eligible to opt-in to the ICI, Enova will contact you directly with information on how to register.
