  1. Clean Power Water Sustainability Workshop A Smart-Phone Application for Home Emissions Estimates Michelle M. Rogers, Michigan Department of Environmental Quality Carol J. Miller, Shawn P. McElmurry, Guoyao Xu, Weisong Shi, Caisheng Wang, Cheng-Zhong Xu, PhD Wayne State University – College of Engineering

  2. WHY? Energy –Emissions Total generation: 4,120 billion (kWh) 3,950 billion (kWh) in 2009 Source: http://www.eia.doe.gov

  3. Polluting Emissions from Electricity Generation http://www.gpo.gov/fdsys/pkg/FR-2012-02-16/pdf/2012-806.pdf http://www.epa.gov/mats/actions.html

  4. Emissions Effects • Air Quality • Visual • Health (asthma) • GHG………Climate (?) • Contaminant Deposition • Surface Water • Soils • Vegetation • Food Chain • Fish Consumption • And,….Even for the “non-environmentalist”……… • Policy: Government Specified Caps

  5. Locational Marginal Price as Proxy for Generator Type Price ($/MWh) LMP at time ti Hydro & Nuclear Coal Natural Gas Oil Problem: How to identify emission potential?

  6. Locational Marginal Prices (LMP) • LMPs based on marginal cost of supplying the next increment of electric demand at a specific location • LMP Accounts for: • generation marginal cost (fuel cost) • physical aspects of transmission system (constraint in transmission lines) • Cost of marginal power losses

  7. Methodology Use LMP to point to the marginal fuel type Calculate emissions associated with that fuel type for a specific area (or specific generator)

  8. Environmental OptimizationLinking Consumption to Emissions • Source Identification • Dispatch adjusted every 5 minutes within MISO • Emission Quantification • Function of generator type

  9. Locational Marginal Prices • LMPs available from MISO • (Midwest Independent System Operator) • LMPs for select Commercial Pricing Nodes (CPNs) available every 5 minutes

  10. Locational Marginal Prices…spatial variation LMP = f (space,time)

  11. Locational Marginal Prices….temporal variation

  12. Emission Rates • LMP  Marginal Generator Type  Air Emissions • Measured Air Emissions Data from EPA’s eGRID • (Emissions & Generation Resource Integrated Database) • Data on thousands of power plants in the US • Sort by EGCL code (Electric Generating Company, Location-Based) • i.e., all of DTE-operated plants in SE Michigan WE WANT THIS TO BE DEFINED ON THE FINEST GRID POSSIBLE….compare to an approach based on national averages of emissions/KWh

  13. Emission Rates Calculate average emission rate for entire area for each fuel type Example, Detroit Edison: (2008 data) LMP  Marginal Generator Type  Air Emissions

  14. Putting it Together: the HERO app HERO = Home Emissions Read-Out (LMP  Marginal Generator Type  Air Emissions) Applying this concept to household energy use Android App for smart phones

  15. HERO ARCHITECTURE HERO: Home Emissions Read-Out

  16. HERO Input • HERO can automatically find nearest CPN based on phone’s GPS • User also has choice to pick location from map

  17. HERO Output • Current, Past, and Projected Future emissions • CO2, NOX, SOX, Mercury, Lead

  18. HERO Screen Shots

  19. User can view more to see background information on CO2, NOX, SOX, Mercury, Lead • Environmental Effects, Human Health Effects • Example: NOX & SOX

  20. LEEM: Locational Emissions Estimation Methodology

  21. HERO published in GooglePlay https://play.google.com/store/apps/details?id=com.amaker.herotest&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5hbWFrZXIuaGVyb3Rlc3QiXQ..

  22. Improvements?

  23. Server-Based Approach

  24. Test Case of Emissions Benefits

  25. BEST/WORST CASE PERFORMANCE

  26. Great Lakes Benefits

  27. Extension of Project

  28. Thanks to Great Lakes Protection Fund THANK YOU Water Sustainability Workshop: A Smart-Phone Application for Home Emissions Estimates
