Green Button Alliance

This past Thursday, our own Andre Sochaniwsky and Roman Grod had the opportunity to demonstrate the need for electronic data sharing in Ontario, during a session hosted by the Ontario Energy Board on the Green Button initiative. Green Button is a data standard that provides homes and businesses with more choice on how to access electrical and natural gas usage data so that we can all work together to increase energy efficiency.
Utilities’ Green Button Implementations to be Certified as Compliant by the Green Button Alliance

       Utilities provincewide to implement Green Button standards-based solutions, certified by the Green Button Alliance, by 01 November 2023. Removing the barriers to energy data access, the utilities’ Green Button Connect My Data (CMD) platforms will enable customers to digitally access their standardized energy data and choose to securely share their data with authorized third-parties and applications

       Green Button CMD implementations will enable utilities to offer energy data -driven solutions that empower customers to make informed decisions about their energy usage, simplify energy management for property managers, and streamline energy consumption reporting required for commercial buildings, while ensuring customer data privacy.

October 28, 2021–The Green Button Alliance (GBA), which fosters the development, compliance, and widespread adoption of the industry’s Green Button Connect My Data (CMD) standard commends the Ontario Ministry of Energy for its leadership and dedication to empowering people and businesses in Ontario with digital access to their energy-consumption data and applauds Ontario’s government for its passage of Ontario Regulation 633/21: Energy Data. Ontario’s new energy data regulation, filed 02 September, requires electric and natural gas utilities across the province to implement Green Button Connect My Data solutions that adhere to the North American Energy Standards Board’s (NAESB) REQ.21 Energy Services Provider Interface (ESPI) version 3.3 standard (commonly known as the Green Button), by 01 November 2023. To ensure critical benefits of the Green Button standard are gained—including customer-data privacy and seamless data interoperability and scalability—the utility-provided Green Button implementations are required to be certified by the Green Button Alliance as compliant to the standards. Green Button energy data access solutions will empower Ontarians with detailed knowledge of their energy-usage patterns and will support energy-efficiency, cost-savings, deployment of clean energy solutions, and decarbonization in the province.

Enabled under Ontario’s Electricity Act, 1998, section 25.35.8: Energy DataRegulation 633/21: Energy Data requires Ontario utilities to implement Green Button Connect My Data (CMD)and Download My Data (DMD) solutions that enable customers to easily obtain and share their data with authorized third-parties that can analyze the data to help them make informed energy-management decisions to reduce energy-use and costs. In support of the province’s electricity and natural gas sectors, the Ontario Energy Board (OEB) led a series of Green Button implementation task force meetings comprised of stakeholders, including members of the Green Button Alliance, and is developing Green Button implementation guidance based on the task force’s recommendations.

“Ontario is helping families and businesses save energy and save money with the push of a button,” said Todd Smith, Minister of Energy. “Ontario’s Green Button initiative will allow consumers to access their natural gas and hourly electricity consumption data through secure apps on their computer or smartphone and find customized tips on how to boost home energy efficiency and lower monthly bills.”

In addition to benefitting Ontario’s residential and business customers, access to Green Button solutions—that provide energy data in the machine-readable Green Button format—will simplify energy management for property managers. For building owners and operators, Green Button solutions can support energy-usage reporting required by Ontario Regulation 506/18: Reporting of Energy Consumption and Water Use, commonly known as the Energy and Water Reporting and Benchmarking (EWRB) initiative. For utilities, their Green Button CMD platforms will enable them to engage with their customers through new applications and services, and enable greater customer participation in Demand Response (DR), that utilize interval data. In addition, Green Button CMD platforms can provide a path forward for integrating customer-sited distributed energy resources (DERs) into the grid.

“The GBA commends Ontario on its leadership in setting-forth a policy that unlocks customer energy data and makes it secure and portable—laying the foundation for a connected and energy-efficient future for the province,” said Jeremy J. Roberts, Executive Director, Green Button Alliance. “Utility implementation-testing and Green Button Certification will ensure the utilities’ solutions are consistent and will enable everyone—residences, energy managers of buildings, and third-party service providers—to participate in a modern energy ecosystem.”

Green Button Solution Testing & Certification:

Several utilities in Ontario already provide Green Button solutions to their customers. Extending the reach of Green Button solutions, Ontario’s energy data mandate applies to approximately 60 electric and natural gas utilities provincewide. The regulation, which goes into force 01 November 2021, directs the utilities to implement the NAESB’s REQ.21 ESPI Model Business Practices, version 3.3 standard, commonly known as the Green Button. This latest version of the standard, published 30 January 2020, should be purchased from NAESB prior to solution testing by the Green Button Alliance. GBA testing and Certification of compliance to the standard assures utilities they have implemented the standard correctly and the solution will provide data in an interoperable format; protect customer data privacy through secure transmission of data; and speed application on-boarding and scalable data-sharing implementations to market. Learn about the GBA’s Testing and Certification program.

“NAESB applauds Ontario’s government for unleashing digital access to standards-based energy data which is key for efficiently quantifying and managing energy consumption for multiple sectors,” said Cade Burks, Vice Chairman, Board of Directors, NAESB and Chief Digital Officer, Big Data Energy Services. “Utilities implementing customer-facing solutions that leverage NAESB’s ratified REQ.21 ESPI standard version 3.3, known as the Green Button standard—that are tested and certified by the Green Button Alliance—are assured of interoperable and scalable solutions that can flexibly meet a variety of current and future needs of energy users in the province.” 

About Green Button Connect My Data (CMD):

Green Button Connect My Data (CMD) is the industry standard for accessing and securely sharing energy- and water-usage data. Green Button CMD allows utility customers to digitally access their electricity-, natural gas-, or water-usage data and choose to authorize secure transfers of their data to third-parties and applications; enabling users to gain additional insights into managing and conserving their resource consumption. For energy managers of properties, access to standardized Green Button energy data in the Green Button XML data format significantly streamlines energy-management and consumption reporting. Utilities can maximize their metering infrastructure by utilizing their Green Button CMD platform to offer a host of new energy-data –enabled services. Third-party developers using standardized Green Button technology can more-rapidly develop applications and services that work seamlessly with other Green Button implementations.
