  1. The Renewable Portfolio --- Defined & Refined Florida Public Service Commission Workshop July 26, 2007

  2. Definition by Technology • Absolute method • Traditional method • Focus on present or near-term technology • Generally exclusive, Specifically inclusive 366.91(b)  "Renewable energy" means electrical energy produced from a method that uses one or more of the following fuels or energy sources: hydrogen produced from sources other than fossil fuels, biomass, solar energy, geothermal energy, wind energy, ocean energy, and hydroelectric power. The term includes the alternative energy resource, waste heat, from sulfuric acid manufacturing operations. 377.803(6)  "Renewable energy" means electrical, mechanical or thermal energy produced from a method that uses one or more of the following fuels or energy sources: hydrogen, biomass, solar energy, geothermal energy, wind energy, ocean energy, waste heat, or hydroelectric power.

  3. Definition by Attribute • Flexible method, emphasis on Results • Allows future technologies • Generally inclusive, Specifically exclusive • Special “riders” to include a target method • Specific “set-aside” for favored attributes For Example: For purposes of this standard, “Renewable Energy" means electrical energy produced (or directly and quantifiably displaced) from a method with: 1] No extraneous limits on the prime energy source, 2]No environmental detriments from prime energy source acquisition, 3] No net release of carbon dioxide or other pollutants. Electric energy derived from “Acoustic Kryptonite Hyperdrive Technology” does not qualify as renewable energy under this standard. Reductions (from 2007) by utilities in system operations energy losses also qualify as renewable energy under this standard. No less than ten percent (20%) of the energy required by this standard shall be derived directly from solar energy.

  4. Attributes: Electric Energy Production Technologies * My opinion Generally no issues Some issues

  5. Attributes: Electric Energy Displacement Technologies * My opinion

  6. Utility Efficiency Technologies Attributes not applicable…

  7. Renewables Refined “...with a strong focus on solar and wind energy...” --EXECUTIVE ORDER NUMBER 07-127 After initial screen, shades of green…

  8. Solar Energy: 2020 Quick Calculations - Reasonable Assumptions • Single-Family Residential • Economic Installations Only – no subsidies • Assumed Net Energy for Load is 340,000 GWH Solar Thermal (DHW) brings 2% of NEL Solar Photovoltaic (PV) brings 2% of NEL  4% NEL (20% of RPS) is Feasible and Economic!

  9. Solar Energy: 2020 -- Other Opportunities • PV Parity expected 2010-2012 & No Real Limits on Land • Commercial PV (Big Box, malls, attractions, etc) • State & Local Govt rooftops PV (schools, offices, conv centers) • Parking Canopies PV (Shade asphalt for fee, market advantage) • Linear PV farms: edge-of Transmission RoW • Linear PV farms: edge-of & median-barrier, Interstate Highways • PV Farms: Restricted-use (airports, brownfields, retention ponds) • Rooftop Leasing: the “4&20” Plan-individual & utility joint venture • Natural Gas continues to climb • Solar Thermal- Commercial (hotels, dorms, food processing) • Reconfigure Multi-Family: Common SDHW sys, metered to units • ST Assist for Adsorption Chilling – BIG potential in FL! More than 10% of NEL is Likely

  10. Recommendation (Our Suggested Definition of the Definition Process) • Statutory and Regulatory Definition by Attribute • Technology Approval by Simple, Streamlined Regulatory Process • Category or Scenario Approval • Appeal & Dispute Resolution, etc. • Monitoring, Verification and Reporting by state agency • 20% of RPS as Solar Energy Set-Aside

  11. Results-Based Realities Awareness and Acceptance of Solar Thermal Energy as a major RPS resource for Florida

  12. PERCEPTION BECAUSE etc, etc…

  13. REALITY 1 KWHT = 1 KWHE BECAUSE 1 KWH= 1 KWH EVERY DAY, EVERY WAY

  14. ENERGY 1 kilowatthour (kWh) is the Energy needed to raise the Temperature of 409 gal of Water by 1o F

  15. Given: Result: • Subdivision w/o gas = Electric water heaters • Solar-Thermal WH = Less electric energy • Metered Solar WH = Measured, verified displacement of electric energy or: 1.0 kWhSTEEEC=* 1.0 kWhELEC ! * Actually, 1.0 kWhSTEEEC> 1.0 kWhELEC(Ask me why)

  16. Equality !! --Consider “Normal” PV: 3060 kWh/yr Green Energy Solar Energy PV Panel(AC Module) D Green Energy Display M 900 kWh/yr Electric Energy Meter Standby Losses Water Heater Electric Energy from Grid Thermal Energy to Tap M M 2940 kWh/yr 6000 kWh/yr Thermal Energy Meter 5100 kWh/yr Electric Energy Meter “Green” Energy Thermal Energy Electric Energy

  17. Now Place the “Green Shroud”: 3060 kWh/yr Green Energy Solar Energy PV Panel D Green Energy Display M 900 kWh/yr Standby Losses Electric Energy Meter Water Heater Electric Energy from Grid Thermal Energy to Tap M M 2940 kWh/yr 6000 kWh/yr Thermal Energy Meter 5100 kWh/yr Electric Energy Meter “Green” Energy Thermal Energy Electric Energy “Pay no attention to the man behind the curtain..”

  18. Then Reveal: 3060 kWh/yr Green Energy (Undisputed, 100%, Grade A, Prime Choice) Solar Energy D Thermal Panel Green Energy Display S 900 kWh/yr Standby Losses - + Water Heater Electric Energy from Grid Thermal Energy to Tap M M 2940 kWh/yr Thermal Energy Meter Electric Energy Meter 5100 kWh/yr “Green” Energy Thermal Energy Electric Energy

  19. “If the Inputs & Outputs are IDENTICAL, any two systems are EQUIVALENT-- It doesn’t matter what is in the Black Box…” Submitted for your consideration: How do we know they identical? – We Measure the All-Important METER: ( Output Displayed in kWh )

  20. Concept Established– other direct electric offsets • Solar Thermal assist for Adsorption Chilling • Solar Thermal space heat • Solar Thermal Process Heat

  21. RPS & Solar Water Heating – now 7 states Source: DSIRE, North Carolina Solar Center & Interstate Renewable Energy Council

  22. Florida Solar Energy Center Creating Energy Independence Since 1975 A Research Institute of the University of Central Florida

  23. For Further Information Bob Reedy, Director – Solar Energy Division reedy@fsec.ucf.edu (321) 638-1470 Philip Fairey, Deputy Director pfairey@fsec.ucf.edu(321) 638-1005 James M. Fenton, Director jfenton@fsec.ucf.edu(321) 638-1002 Main FSEC web site www.fsec.ucf.edu

  24. Appendix A: The Language Solar Thermal-to-Electric Energy Equivalency Credit (STEEEC): “A standard unit of used and useful thermal energy generated from solar sources, directly displacing thermal energy otherwise generated from electric sources, and equal to the amount of electric energy displaced”

  25. When Selling Energy... The Meter is Critical !! • Feedback to the Host • Detect malfunction • Quantify pollution reduction • Feedback to the Owner (if different) • Detect malfunction • Verify return on investment • Record of generated STEECCs • Feedback to the Green Power Market • Certify Green Power and Green Tags

  26. the All-Important METER: Important Note: Output Displayed in kWH !!

  27. Meter Costs are falling • No fuel burned • Allows “no more than” approach • Owner choice: more accurate meters for more credit • Utility Scale Volumes • Solid State In-line flow meters coming available • No maintenance, no decline in registration • Low Cost Temperature Sensors • Read-by-email-digicam method (w/ spot audit) • New FSEC Meter Method • Modeling of Standby Losses • One more Temperature sensor (ambient) • Eliminates electric meter of backup source
