Green Button Platform


Green Button is a way to download or connect utility-usage data (electricity, gas, water) to gain a better insight into waste and inefficiencies, allowing customers to make adjustments to use fewer resources and even save money. 

On November 1st, 2021, Todd Smith, Minister of Energy for Ontario, announced a mandate requiring nearly all regulated Ontario electricity and natural gas utilities to provide Green Button to their customers within twenty-four months. As an early adopter of Green Button since 2015, London Hydro has extensive knowledge in implementing two key Green Button standards for electricity, natural gas and water usage data.

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 are able to rapidly create and offer these products, services, and applications.

London Hydro has extensive experience successfully implementing Green Button for several partners nationally in the electricity, water, and gas industry.
