Many utilities are implementing Green Button Download My Data which means that the utility customer can download their own energy consumption data directly to their own computer, and if they so choose, upload their own data to a third party application. The ESPI data standard can also be extended in the future to support natural gas and water usage information and other uses, and these options are being explored. The Green Button Initiative is not limited to utilities that have deployed smart meters that produce very detailed information about energy consumption, but also includes utilities that are able to provide only monthly billing data. The data can be provided in 15-minute, hourly, daily, or monthly intervals depending on what a utility decides to make available and what level of detail they are able to provide.

The Green Button data standard is flexible enough to handle different types of energy data and time interval usage, and applications are being developed for both residential and commercial customers.

All of the utilities that have committed to Green Button will implement the common XML data format in an easy to download manner. The ESPI standard consists of two components: 1) a common XML format for energy usage information and 2) a data exchange protocol which allows for the automatic transfer of data from a utility to a third party based on customer authorization. The data standards development process was facilitated by the Smart Grid Interoperability Panel, a public private partnership that is facilitated by the National Institute of Standards and Technology (NIST). Green Button is based on the Energy Services Provider Interface (ESPI) data standard released by the North American Energy Standards Board (NAESB) in the fall of 2011. Public Service Company of New HampshireĬompanies Currently Support or Pledging to Support Green Button Data:.Utilities Committed to Implementing Green Button: The following utilities have already committed to Green Button: Ameren Illinois, American Electric Power, Austin Energy, Baltimore Gas & Electric, CenterPoint Energy, Chattanooga EPB, Commonwealth Edison, Glendale Water and Power, National Grid, NSTAR, Oncor, Pacific Power, Pepco Holdings, PG&E, PECO, Portland General Electric, PPL Electric Utilities, Reliant, Rocky Mountain Power, SDG&E, Southern California Edison, TXU Energy, and Virginia Dominion Power. This number will continue to grow as utilities nation-wide voluntarily make energy data more available to their customers in this common, machine-readable format. In total, these commitments ensure that over 60 million homes and businesses will be able to securely access their own energy information in a standard format. To date, a total over 50 utilities and electricity suppliers have signed on to the initiative. The Green Button initiative was officially launched in January 2012. What has been the success and progress on the initiative to date?

Voluntary adoption of a consensus industry standard by utilities and companies across the country both enables and incentivizes software developers and other entrepreneurs to build innovative applications, products and services which will help consumers manager energy use by, for example, programming their home energy management devices, sizing and financing rooftop solar panels, and helping a contractor to verify their home energy savings more cost-effectively.Īdoption of the Green Button data standard will also benefit utilities that receive numerous requests for data, are administering energy efficiency programs, are looking for avenues for greater customer engagement, and in many other ways. With their own data in hand, consumers can take advantage of a growing array of online services to help them manage energy use and save on their bills. Customers are able to securely download their own detailed energy usage with a simple click of a literal "Green Button" on electric utilities' websites.

The Green Button initiative is an industry-led effort that responds to a White House call-to-action to provide utility customers with easy and secure access to their energy usage information in a consumer-friendly and computer-friendly format.
