We are moving the Developer Site to new servers and a new look-and-feel to better-serve videos and tutorials that explain how to implement the Green Button - to read the files/streams. And, for utility developers: to make it easier to write the files/streams. If you are a programmer, please visit our new Github site:
In that idea, we are improving the sample code we make available for you to do your implementations; including working to provide samples on various platforms. We are also looking to help integrate with the NREL utility-rate database and provide better-integration with the EPA's EnergyStar Portfolio Manager.
Certification of utility Download My Data (DMD) and Connect My Data (CMD) are available today. We're working on certification for third-party applications; look for more in early 2020 at www.greenbuttonalliance.org
“Utility-provided Green Button customer usage data are highly sought-after by solar and solar software companies as it enables solar installers, financiers, and energy service companies to evaluate projects and savings faster and with more accuracy. Public-purpose programs, including demand response and energy efficiency programs, also benefit.”
