Source: What is Green Button? Common-sense idea that electricity customers should be able to download their own energy usage information in a consumer- and computer- friendly 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: public facing websitewww.greenbuttondata.org – 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

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. Empower Consumers and Spur Innovation

Source: 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. – PG&E Currents

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 Access FOA recipients
