    7. WHPT has a clear vision of what is needed to greatly expand the use of wind energy to meet the nations energy needs Benefits include: over $1 trillion in economic investment and over $400 billion in total cumulative economic impacts half a million jobs for wind machine manufacturing, installation and operations new property tax revenues of over $1.5 billion over $600 million in annual payments to rural landowners. natural gas demand reduced by approximately 7 billion cubic feet/day, nearly half of the current consumption in the electric sector, and natural gas prices reduced by approximately 12%, saving consumers approximately $128 billion over the 23 years. 825 million tons of CO2 emissions avoided in the electric sector in 2030, equivalent to 25% of expected electric sector emissions; reduced water consumption in the electric sector by 8%, or 4 trillion gallons, enough to supply Denver for 200 years. U.S. installed capacity from AWEA/GEC database. Estimated wind electricity generation from AWEA/GEC installed capacity, assumed fleet average capacity factor of 29% derived from AWEA report, http://www.eia.doe.gov/neic/quickfacts/quickelectric.html (reviewed April 2007) Global installed capacity from GWEC.netU.S. installed capacity from AWEA/GEC database.

    9. 9 Systems Integration Program

    10. 10 Wind Energy Integration Challenges: Transmission Interconnection & Congestion Lack of Knowledge on Operational Impacts and Integration Costs of Wind Energy Shortage of power system professionals with knowledge of wind energy Policy Treatment of Wind Energy as an Electricity Resource DOE Action: Assess Wind’s Potential to serve our Nation’s Electricity Needs Develop tools to assist the electric utility industry analyze wind energy Perform Operational and Interconnection Studies with industry stakeholders Nationwide Provide wind energy education & create curriculum to train the next generation of power system professionals on wind energy Reach out to Federal, State, and Local stakeholders on the challenges and solutions to Wind Energy Integration Results: Set the path for the wind industry to accelerate its proliferation Increase body of knowledge on wind energy integration Help grow the delivery of emission-free energy from roughly 1 percent to the AEI’s vision of 20 percent of our Nation’s electricity usage

    11. 11 Wind Resource Assessment Meso-scale Modeling – 100 meter, 2km, 10min, 3yr wind resource model for all of US –to be completed in 2009. Forecasting – Perform needs assessment, create a multi-year plan and quantify value Tall Tower Measurement – Complete a needs assessment and create a prioritized multi-year plan. Data Storehouse Creation – Ensure that current and future data is available to the public in a “ready-to-use” form. Create an industry standard format & incorporate visualization tools

    12. 12 Modeling Methods Development Dynamic Turbine Models Create models of commonly used turbines for electric utility modeling software System Operations Simulators Provide the capability for electric utility operators to simulate operations with large amounts of wind energy on their systems Wind Energy Integrated Resource Planning Tools Build the tools utility system planners need to better integrate wind energy into their generation resource mix Forecasting Methods & Tools Provide control room level tools for system operators to anticipate the near term wind resource

    13. 13 Operational & Interconnection Studies Interconnect Wide Studies Western & Eastern grid wide, high penetration wind integration studies with broad stakeholder participation. The first of these will be completed in 2008. Market Value Analysis Determine Wind’s current and future value in electric energy markets including its value as a hedge against future fuel price increases, carbon tax, etc. Conditional Firm Transmission Tariff Work with electric utilities on the effect FERC order 890 will have on the ability to integrate increasing amounts of wind energy into the transmission system. Operational Integration Studies Leading the effort to get control room level integration studies into the hands of stakeholders Small System Integration Investigate how wind integrates differently into islanded and small power systems.

    14. 14 Outreach & Education Engineering Program Development Fund the creation of courses/programs for wind energy at the university level. Trade School Program Development Fund the creation of courses/programs for wind energy at the university level. Policy Outreach Create targeted informational materials for National, State, and Local policy and trade organizations to publish for their membership.
