Avila Beach Wave Energy Presentation Draft 02.15.2011

  1. 1. Avila Beach, CA WAVE Energy Power Generation Plant Presented by: Martha Bell, Sarah Capudi, and Jennifer Foronjy
  2. 2. Introduction <ul><li>Community Energy Needs </li></ul><ul><li>Project Description </li></ul><ul><li>Project Benefits </li></ul><ul><li>Project Impacts </li></ul><ul><li>Mitigation </li></ul><ul><li>Project Costs </li></ul>
  3. 3. Avila Beach Energy Needs Population of San Luis Obispo County – 265,927 * Population of Avila Beach – 797** Avila Beach = <1% of county Energy Consumption by SLO County - 1,749,000 MWh*** Estimated Avila Beach Energy Use – 17,490 MWh/year *US Census, 2008 ** US Census, 2000 ***California Energy Consumption Data Management System, 2008 17,490 X .10 = 1,749 MWh from proposed project
  4. 4. Project Description <ul><li>Offshore converter on the coast of Avila Beach </li></ul><ul><li>Energy converted to a 60-Hertz frequency </li></ul><ul><li>Continuous energy supply due to high predictability </li></ul>Avila Beach
  5. 5. Project Benefits <ul><li>No air pollution </li></ul><ul><li>Renewable resource, will always be readily available </li></ul><ul><li>High reliability </li></ul><ul><li>Increased energy independence </li></ul><ul><li>Use of existing transmission and distribution system out of Diablo Canyon Power Plant </li></ul>
  6. 6. Project Impacts From Socio-Economic Factors, Habitats, and Species to Acoustics and Electromagnetic Fields
  7. 7. Socio-economic Impact <ul><li>Commercial and recreational fisheries </li></ul><ul><li>Marine transportation </li></ul><ul><li>Recreational boating </li></ul>
  8. 8. Intertidal and Benthic Habitat <ul><ul><li>Larval distribution in the Intertidal zone </li></ul></ul><ul><ul><li>Initial construction and routine maintenance of mooring lines may adversely affect the benthic habitat </li></ul></ul>
  9. 9. Fish Effects <ul><li>Wave energy can affect community structure through changes in species composition and predator effects </li></ul><ul><li>Attracting previously absent predators </li></ul><ul><li>Some fish species such as sharks, rays, and skates are very sensitive to acoustics which could affect the food chain </li></ul>
  10. 10. Marine Mammals <ul><ul><li>Entanglement issues with mooring cables </li></ul></ul><ul><ul><li>Hydraulic fluids </li></ul></ul><ul><ul><li>Interference with migration patterns caused by EMF </li></ul></ul>
  11. 11. Mitigation Protecting, Restoring, and Enhancing the Environment
  12. 12. Receptor Breakout Groups <ul><li>1. Socio-economic effects: de facto marine reserve </li></ul><ul><li>2. Nearshore Intertidal and Benthic Habitat, Fish Effects, and Seabirds: adaptive management </li></ul><ul><li>3. Marine Mammals: work with regulatory staff </li></ul><ul><li>4. Physical Environment : no new infrastructure </li></ul>
  13. 13. Stressor Breakout Groups <ul><li>1. Electromagnetic Effects </li></ul><ul><li>Armoring and trenching cables is expected to be effective </li></ul><ul><li>2. Adaptive management & mitigation </li></ul><ul><li>Devices which break loose </li></ul><ul><li>Debris accumulation </li></ul><ul><li>Hydraulic fluids which leak </li></ul><ul><li>Acoustics </li></ul>
  14. 14. Protecting, Restoring, & Enhancing the Environment <ul><li>As the DCPP is phased out of production in the future, PG&E will work with the National Park Service to establish a National Seashore along the Diablo Canyon shoreline, creating a protected natural resource for future generations. </li></ul>
  15. 15. Project Costs
  16. 16. PG&E Humboldt Wave Connect Project (on hold as of November 2010) <ul><li>5 MW capacity </li></ul><ul><ul><li>Regulatory Process - $6 million </li></ul></ul><ul><ul><li>Installation, transmission and distribution - $50 million </li></ul></ul><ul><ul><li>Operation and Maintenance - $5 million annually </li></ul></ul><ul><ul><li>Mitigation costs??? </li></ul></ul>
  17. 17. Questions??? Questions?
