Green Button Data

Ontario is providing families and businesses more control over their electricity and natural gas bills with the introduction of the new Green Button Standard that will allow access to their data with a 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.

Green Button provides a unified, industry-standard data format, which can be used to analyze and manage a consumer’s energy usage. The introduction of Green Button industry-standard data across Ontario utilities will provide the foundation for the development of new tools and applications for customers to analyze and monitor their energy usage to reduce costs.

Below are just a few of the 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.

Green Button Data for Residential and Small Commercial Customers:

• Many customers are already viewing their energy data through a customer portal on their utility website. With Green Button, third party apps can analyze the data and provide insights to help customers make sense of their energy use and make informed decisions to help reduce costs.
• With CMD, data is shared on an ongoing basis. This allows third parties to provide insights and alerts on usage trends and changes.

Green Button Data for Businesses:

• For customers with a large number of properties across multiple utilities, Green Button provides a standardized format so that the data they receive from each utility is in a similar format. Green Button third parties in the commercial sector are able to analyze large volumes of data across multiple facilities to provide energy management advice.
• With CMD, data is shared on an ongoing basis. This allows third parties to provide insights and alerts on usage trends and changes including monitoring the impact of energy efficiency measures taken.
• Green Button will also make it easier for facilities to complete mandatory government reporting requirements.

What format will my data be downloaded in?

When you download your data, it will be in an industry-standard XML format. Please note that XML files are designed to be read and analyzed by computer applications, not humans.

The Green Button Connect My Data (CMD) standard, also referred to as Data Shares is the industry standard for securely authorizing and sharing electricity usage data with registered third-party vendors. With CMD, utility consumers can digitally authorize their usage data to be shared with energy-efficiency applications, clean energy companies, analytics firms, and others, who can view and analyze the data and provide insights into managing and conserving resource consumption.

Example 1: If you are considering installing or have installed solar panels on your home or business, you can connect the solar company to your Green Button usage data to analyze the return on your solar panel investment and make informed decisions about future investments.

Example 2: Commercial or industrial customers with multiple locations across different utility territories can access and analyze energy usage data from all sites in a consistently standardized format.

Sharing your data starts on the third-party vendor’s website.

• Go to the authorized third-party vendor’s Green Button registration web page
• Complete the third-party vendor data sharing authorization request form
• You will be redirected to Hydro 2000's Green Button portal to authenticate, verify the data sharing information, review the terms and conditions, and authorize data sharing.
• Hydro 2000 will then exchange a security token with the authorized third-party vendor which will allow secure, automated data sharing

When authorizing a third-party vendor to access your data, you will select the type of data you want to share with them and for which account (if you have multiple accounts). You can select your Energy Usage Data, Billing Data and/or Account Information to be shared. Your utility provider will share the type of data you have selected and authorized for that account.
