Green Button is a common data standard that is being adopted across North America to allow consumers to share their electricity consumption data with app developers and solution providers in a secure and privacy-enabled way. Instead of having to customize your solution or service for every utility in the province, you can now develop products based on a standard data format that works across Ontario and conforms to a similar standard in the US.

Green Button allows you to easily access a customer's energy usage information and provide your value-added insights, recommendations and controls. Discussions are under way to extend Green Button to natural gas as well. 


  • 4.6 million smart meters in Ontario
  • Over 60% of Ontarians have access to Green Button (Download My Data) and 100 million customers in the US have access
  • 10 utilities in Ontario are already on board

Green Button is not a proprietary software solution but an industry standard that allows you to build your own solution.
