FAQs

There are two types of data within the Green Button standard – “Energy Usage Data” and “Account Information”. 

“Energy Usage Data” includes 24 months of historical and ongoing meter readings and dates, billing period dates, usage data, electricity charges, etc. where available. Usage data is provided in the interval provided by the meter.

“Account information” includes bill details, mailing name and address, service address, account number, meter number, rate class, etc.

Green Button® downloads are in XML (computer-readable for analysis). This format is used because it allows different systems and applications to interpret and use the data effectively.

You can also share this file with third-party developers who can help you get better insights into your consumption patterns, allowing you to make adjustments to save energy and reduce costs.

Hydro Ottawa’s Green Button “Connect My Data” and “Download My Data” services are free of charge.

“Connect My Data” allows customers to digitally authorize their energy usage and account information to be safely shared with third parties who can view and analyze their data and provide additional insights into managing and conserving energy. For example, these third parties may be clean energy companies, or analytics firms who can view and analyze your data and provide additional insights into managing and conserving energy. We recommend researching third-party companies before connecting with them to make sure they meet your needs.

Customers wishing to authorize third-party access to their account information must first start in the third-party software. Third-party providers will then link you to Hydro Ottawa's Green Button authentication process so you can log in and select what information you want to share with them.

Yes, you can revoke access to third parties at any time. Please visit Hydro Ottawa’s Green Button access page and log in using your MyAccount credentials or sign in using the information from your last bill.
