What is Green Button?
Common-sense idea that electricity customers
should be able to download their own energy
usage information in a consumer- and computerfriendly format.

Green Button – What is it?
• Standardization: Common xml format based on standardized
information model (Energy Services Provider Interface – North
American Energy Standards Board)
• Branding: www.greenbuttondata.org public facing website
– Green Button Download My Data
– Green Button Connect (Green Button Connect My Data)
• User communities: Open Automated Data Exchange
• Applications: DOE Apps for Energy, Smart Grid Data Access
FOA, Hack-a-thons, vendor implementations, apps
repositories
• Future: Continued work to engage stakeholders and recruit
implemeters, firm up formats, revise/profile standards
including international, add testing/certification, privacy
policies
More Details
Markets: Residential, commercial and industrial
Type: initially electric consumption data , but the data standard is extensible
to gas and water data
Timeliness: Data is typically at least 24 hours old; up to 12 or 13 months
worth of data
Time interval:
• Again the data standard is extensible and could include any interval of
data (monthly, hourly, 15 minute)
• Many utilities will provide hourly data or 15 minute interval data.
• However, some will provide monthly data
Metering system:
• AMI or AMR; however smart meters are not required (example: monthly)
Transfer of data:
• Green Button Download My Data –direct download from the utility to
the customer, safely and securely
• Green Button Connect (My Data) - automated data transfer from the
utility to a third party with affirmative customer authorization and action
Excitement of initial implementations
and growing commitments
Utilities and electricity suppliers in 24 states across
various regulatory regimes will provide 30 million US
homes and businesses Green Button data…

What might Green Button data be good for?
Empower Consumers and Spur Innovation
Insight: entrepreneur-created web portals analyze energy usage and provide
actionable tips;
Heating and Cooling: customized heating and cooling for savings and comfort;
Education: community and student energy efficiency competitions;
Retrofits: improved decision-support tools to facilitate energy efficiency retrofits;
Verification: measurement of energy
efficiency investments;
Real Estate: provide energy costs for
tenants and/or new home purchasers;
Building Benchmarking: transfer monthly data
Solar: optimize the size and cost-effectiveness
of rooftop solar panels.

What people are saying…
It may finally give consumers a reason to care about the smart grid.
– SF Chronicle
Solar companies are also eager for consumer data because understanding a
homeowner's electricity use is key to the sales process.
– San Jose Mercury News
The project is important because it is a broad-based plan to take energy data and
standardize the format of it, open it up (while also providing security) and make it
readily available to consumers.
– Gigaom
I'm a big fan of simplicity and open standards to unleash a lot of innovation.…I'm going
to reach out to ConEd, the utility in NYC, and find out when they are going to add Green
Button support to their consumers data. I hope it is soon.
– Fred Wilson (Venture Capitalist)
Among those in attendance was software developer Joss Scholten of Austin, Texas, who
created an app in 12 hours using PG&E’s green button. The app, which he displayed on
his iPad, shows hourly, monthly and daily electric usage in a customer-friendly display.

Future Plans
• New SGIP Priority Action Plan 20 for Green Button
– Additional revisions to NAESB standards, international
standardization, development of testing and certification (UCAIug
OpenADE – Open Automated Data Exchange)
• Green Button Download My Data
– Consumers directly download their energy usage information,
typically hourly interval data (available one day later) for previous
13 months, then they can choose to share it with third parties to
receive value-added services
• Green Button Connect (Green Button Connect My Data)
– More persistent and automated data exchange from utilities to
third parties as authorized by consumers
– Uses fuller functionality of NAESB ESPI standard, for utilities that
are ready and interested in implementing
• DOE Smart Grid Privacy program
• Implementations engaging consumers: DOE Smart Grid Data
