Cape Wind Basics

  1. 1. August 6, 2010 www.CapeWind.org www.CapeWind.org
  2. 2. Energy Needs & Choices <ul><li>Energy demand is expected to increase 40% by 2025 </li></ul><ul><li>More coal and oil plants would further damage the environment </li></ul><ul><li>New England is becoming over-reliant on natural gas </li></ul><ul><li>New nuclear plants are not likely </li></ul>August 6, 2010 www.CapeWind.org
  3. 3. Wind Power – renewable leader <ul><li>Fastest growing energy source in the world </li></ul><ul><li>Substantial improvements in design & performance </li></ul><ul><li>12 years successful experience in Europe with ocean-based turbines </li></ul>August 6, 2010 www.CapeWind.org
  4. 4. August 6, 2010 www.CapeWind.org
  5. 5. Why Nantucket Sound? <ul><li>Nantucket Sound is ideally suited for offshore wind energy development </li></ul><ul><ul><li>strong wind </li></ul></ul><ul><ul><li>relatively protected, shallow water </li></ul></ul><ul><ul><li>close to electrical interconnect </li></ul></ul><ul><ul><li>near regional load demand </li></ul></ul>August 6, 2010 www.CapeWind.org
  6. 6. August 6, 2010 www.CapeWind.org Site Analysis Main Shipping Channel Legend 3 Mi. Limit Shipping Flight Cables Ferries
  7. 7. Proposed Site August 6, 2010 www.CapeWind.org Nantucket - 13.8 Miles Cotuit – 6.0 Miles Point Gammon – 4.7 Miles Oak Bluffs - 9.3 Miles Edgartown – 8.9 Miles
  8. 8. Project Description <ul><li>130 Wind turbines, delivering a maximum of 420MW of clean energy </li></ul><ul><li>Grid spacing of approximately 1/2 by 1/3 mile (six by nine football fields) </li></ul><ul><li>246 feet hub height, 417 feet height (at the blade tip), 16 feet diameter at base </li></ul><ul><li>No prohibition of watersheet uses </li></ul><ul><li>Decommissioning plan </li></ul>August 6, 2010 www.CapeWind.org
  9. 9. Cape Wind impacts <ul><li>On average, produce ¾ of the electricity used on Cape & Islands </li></ul><ul><li>600 – 1,000 New jobs to region in wind turbine manufacturing, assembly, ocean construction and 50 maintenance & operations jobs </li></ul><ul><li>Eco-tourism and educational destination </li></ul><ul><li>Lower wholesale electric prices, saving New England $25 million per year </li></ul><ul><li>Reduced air pollution, offsetting over a million tons of CO2 per year = 220,000 cars </li></ul><ul><li>Less demand for imported fuel – all fossil fuels are imported into New England </li></ul>August 6, 2010 www.CapeWind.org
  10. 10. Cape and Islands electric load p rofil e:* <ul><li>Peak load = 440MW </li></ul><ul><li>Average annual load = 230MW </li></ul>August 6, 2010 www.CapeWind.org *Approximate, based on 1999 ISO records Cape Wind will produce 74% of the power used by the Cape & Islands Cape Wind: <ul><li>Peak output = 420MW </li></ul><ul><li>Average output = 170MW </li></ul>
  11. 11. Annual Amounts of Equivalent Fossil Fuel Offset by this Wind Power Project <ul><li>Oil - 113 Million gallons or </li></ul><ul><li>Coal - 570,000 tons or </li></ul><ul><li>Natural Gas - 10 Billion cubic feet </li></ul>August 6, 2010 www.CapeWind.org
  12. 12. Specific Environmental Benefits of this Wind Power Project <ul><li>Air Quality Improvements - Emission Offsets* </li></ul><ul><ul><li>SO 2 - 4,574 tons per year (Acid rain) </li></ul></ul><ul><ul><li>NO x - 1,401 tons per year (Smog) </li></ul></ul><ul><ul><li>CO 2 - 1,097,000 tons/yr. (Greenhouse gas reduction) </li></ul></ul>August 6, 2010 www.CapeWind.org * Based on rates per: 2000 NEPOOL Marginal Emission Rate Analysis

  15. 15. Permitting Process <ul><li>Federal NEPA and State MEPA Reviews, seventeen participating agencies </li></ul><ul><li>Tougher environmental permit review than was required of any coal, oil, or gas power plant in New England. </li></ul><ul><li>The Environmental Impact reviews will cover alternative site analysis, project impacts on benthic, fish, marine mammals, avian, economic impacts, fishing, aesthetics… </li></ul><ul><li>Will only be approved if federal and state agencies determine the project is in the Public Interest </li></ul><ul><li>Cape Wind is willing to pay a lease to the federal government </li></ul>August 6, 2010 www.CapeWind.org

  21. 21. August 6, 2010 www.CapeWind.org Cape Wind Scientific Monitoring Station ~ Current Conditions In preparation for America’s first offshore wind farm, - capable of powering on average three-quarters of the Cape and Islands with clean, renewable energy - Cape Wind has erected a meteorological data tower on Horseshoe Shoal, in Nantucket Sound. As part of our continued commitment to the community we are providing current weather and sea conditions to the public.   Current Conditions Last updated:    Mon Dec 8 13:00:06 2003 EDST • Surface current speed, direction and water temperature are updated every 6 minutes. Wind speed, wind direction, air temperature and pressure are updated every 10 minutes. Wave height and direction are updated every 30 minutes.
