Green Button is a data standard that provides residential and business energy customers with more choice in how you access your electricity or natural gas usage data.

Green Button applications can analyze this data to provide customers with personalized ways to increase energy efficiencies. This will help customers:

  • save money on their monthly bills
  • reduce demand on the energy system

We introduced a new requirement that beginning November 1, 2021, most regulated Ontario electricity and natural gas utilities must provide their customers with access to their energy usage data in Green Button format no later than November 1, 2023.

Select utilities in the province have already enabled Green Button for their customers. For more information on when Green Button will be available in your area, contact your utility.

How Green Button works

With Green Button, Ontario energy customers can easily access information on how they consume energy at their home or business.

Electricity and natural gas customers will be able to download their natural gas and hourly electricity usage data from their utility in a standardized digital format. Customers will also be able to authorize the secure, automatic transfer of this data to Green Button applications of their choice.

Green Button applications can:

  • provide you with information on your energy usage
  • give you advice on how you can use less energy to help lower your bills, such as customized energy efficiency retrofit options or switching electricity price plans to get long-lasting savings
