Connecting you and your energy usage with Green Button

Green Button is a data standard that provides energy customers with more choice in how they access their electricity and natural gas data. With a simple and secure process, customers will be able to securely download or connect (share) their energy usage data in an industry-standard format with registered third parties.

With the introduction of the new Green Button Standard, Ontario families and businesses have more control over their electricity and natural gas bills by providing access to their data with the goal of better tracking energy use, reducing bills, and saving money.

On November 1, 2021, the Ontario Ministry of Energy announced that electric and natural gas utilities across the province must provide their customers with access to Green Button data no later than November 1, 2023. Read the full news release.

Benefits of Green Button data

Improve energy efficiency

Consumers can use Green Button data to identify and compare their energy usage in order to improve energy efficiency within their home or business.

Reduce energy costs

By learning their usage patterns and habits, consumers can make informed choices about how much energy they use and when they use it. When consumers use energy during off-peak hours (also known as peak-shaving) and invest in energy-efficient appliances, it saves money and can help reduce strain on the grid.

Energy conservation

Consumers can use their data to conserve energy to help reduce their carbon footprint and protect the environment. Green button tools to understand large volumes of energy data will help pave the way for future innovations in the energy sector.

Secure access

With Green Button standards, consumers can rest assured that their data and private information is secure. Utilities must go through a strict testing and certification process to become Green Button standard-compliant.
