Green Button Platform


Green Button is a way to download or connect utility-usage data (electricity, gas, water) to gain better insight into waste and inefficiencies, this allows customers to make adjustments to reduce their usage and save money.

On November 1st, 2021, Todd Smith, Ontario’s Minister of Energy, announced that regulated electricity and natural gas utilities in Ontario are mandated to provide Green Button to their customers within twenty-four months.

The two key Green Button standards for electricity, natural gas and water usage are:

The Green Button Download My Data (DMD) standard enables homeowners and property managers to download their electricity usage data from an energy service provider’s website in an industry-standard XML data format. Energy customers can utilize these data to view their historical and present energy usage, analyze trends, and make informed energy-management choices.

Extending upon the Green Button Download My Data (DMD) standard, the Green Button Connect My Data (CMD) standard allows customers to authorize direct, secure transfer of their energy usage data to third parties that can assist them with easily managing and conserving energy. In addition, due to the use of common, standardized Green Button formats, third-party developers can rapidly create and offer these products, services, and applications.


For Customers

Green Button enables customers to securely transfer their data to third-party solution providers, who can further assist them in monitoring and managing energy, natural gas or water usage. With convenient access to data in an easy-to-understand format, customers can leverage their new-found knowledge and better control and track utility expenses. Customers will be required to log into their ELK Energy MyAccount in order to access the secure Green Button microsite.

For Third Party Providers

Third Parties who wish to be registered and onboarded onto the Green Button Platform to be showcased as an available application in our Green Button marketplace will be required to submit a registration form. Once submitted, our technical team will be in touch with the next steps. We look forward to connecting customers with what you have to offer!
