  4. 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. Source:

  5. 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

  6. 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

  7. Utilities and electricity suppliers in 24 states across various regulatory regimes will provide 30 million US homes and businesses Green Button data… Excitement of initial implementations and growing commitments Green Button commitments Utilities & Electricity Suppliers with Green Button today (almost 10 million homes) • American Electric Power • Austin Energy • Baltimore Gas & Electric • CenterPoint Energy • Chattanooga EPB • Commonwealth Edison • Glendale Water and Power • National Grid • Oncor • PECO • Pepco Holdings • PPL Electric Utilities • Pacific Power • Rocky Mountain Power • Southern California Edison • Virginia Dominion Power • NSTAR • PG&E • Reliant • SDG&E • TXU Energy

  8. The ecosystem of companies and organizations supporting and using Green Button data… Utilities Utility software vendors Apps developers Device manufacturers Standards organizations

  9. New Green Button Apps and Competitions Green Button Apps! http://openei.org http://appsforenergy.challenge.gov/ Consumers challenged to reduce electric use via Smart Meter Texas portal www.smartmetertexas.com Source:

  10. 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 fortenants and/or new home purchasers; Building Benchmarking: transfer monthly data Solar: optimize the size and cost-effectiveness of rooftop solar panels.

  11. 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 Source:

  12. Future Plans • New SGIP Priority Action Plan 20 for Green Button • Additional revisions to NAESB standards, international standardization, development of testing and certification (UCAIugOpenADE – 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

  15. Energy Usage Information • Measurements of power, energy, gas, water, … • Quality: Raw, validated, estimated, … • Source: Meter near real-time, utility back end, third party • Economics: Consumers need to know the cost of their consumed power (but we did not construct a pricing model) • Identification: by customer, device, location • Readings • Interval data • Summary Information • Power Quality Metrics

  16. Standardization: Energy Usage Information Model UsagePoint ServiceCategory EUI comes from and to residences and businesses MeterReading IntervalBlock ElectricPowerSummary IntervalReading ReadingType ElectricPowerQualitySummary ReadingQuality Best practices include modeling information in UML; generating documentation and Schemas directly from the UML for life cycle model and data management Note: This information is multidimensional. Many different reading types, summaries, and readings possible.

  18. Alternate pathways to energy usage information via single format Sources of EUI Uses of EUI Single Data Format: all at once Power Utility Via: ESPI, SEP2, Web Portal Single Data Format: as sequence
