  1. Real Implications of Alternative Energy Sources for Communities WCCMA 2008 Summer Conference Roger Garratt Director, Resource Acquisition & Emerging Technologies August 20, 2008

  2. Agenda • PSE Overview • PSE Renewable Resources • Market Overview • Community Benefits • Conclusions

  3. PSE, a Washington Company • State’s oldest and largest utility, serving more than half of State’s population • Over 1 million electric customers • Over 700,000 natural gas customers • Added 56,000 customers in last two years • Public Service Company with an obligation to serve Sample

  4. PSE Energy Need *Energy need before conservation, includes new contracts, new wind and hydro shapes, and Sumas

  5. PSE Resource Strategy *Lowest Reasonable Cost Resource Portfolio, from May 2007 Integrated Resource Plan

  6. Wind & Solar Acquisitions

  7. New Renewables Renewables Strategy

  8. Greenhouse Gas (GHG) Targets

  9. Renewables development is booming Source: Renewable Northwest Project

  10. LM Glasfiber Little Rock, AK & Grand Forks, ND Gamesa Philadelphia, Pennsylvania Vestas Windsor, Colorado Trinity Structural Towers Clinton, IL & Fort Worth, TX PPG Industries Shelby, North Carolina Knight & Carver Howard, South Dakota TECO-Westinghouse Round Rock, Texas DMI West Fargo, ND & Tulsa, OK Clipper Windpower Cedar Rapids, Iowa Both facilities manufacture blades for wind turbines. All three facilities (2 US and 1 Canada) manufacture wind towers. Manufactures 130- and 144-foot long blades for 1.65 and 3 MW turbines Manufacture and assembly of 2.5-MW Liberty wind turbines and spare parts for support services Multiple plant sites manufacture turbine parts, nacelles and towers for G80, G83, G87 and G90 2 MW machines.. Facility produces high-tech fiberglass for blades; PPG also produces blade and tower coatings Assembles nacelles, using Composite Technology’s DeWind brand turbines; and also produces the rotor hub. Blade construction and repair facility Both facilities manufacture wind towers that support turbines as large as 2.5 MW. Fuhrländer (Proposed) Helena, Montana Will manufacture 2.5 MW AG wind turbine, which has 150-ft. blades Rise in Wind Component Manufacturers in the U.S. Note: Map is illustrative only; it is not intended to be a representation of all wind component manufacturing in the U.S.

  11. $8 million – to local community during construction $1.3 million – 2008 property taxes Hospital $45,000 Local schools $556,442 County $345,248 State $369,156 Lease and royalty payments to state agencies: WDFW $80,000 DNR (schools) $306,000 Economic Benefits – Wild Horse

  12. Tourism • Renewable Energy Center - over 10,000 visitors since opening April 1, 2008 • Guided Tours – over 125 tour groups

  13. Conclusions • Renewable resources are consistent with public interests • Environmental benefits • Sustainability • Energy independence • Community members “connect” with renewable resources • Over time, renewables will become more and more prevalent

  14. Questions?
