EPAct 2005, Section 2606

• The study shall
• Determine the economic and engineering
  feasibility of blending wind and hydropower
  generated from the Missouri River dams operated
  by the Army Corps of Engineers.
• Include an assessment of the costs and benefits
  of blending wind energy and hydropower compared
  to the current sources used for firming power to
  Western.
• Review historical and projected requirements for,
  patterns of availability and use of, and reasons
  for historical patterns concerning the
  availability of firming power
• Assess the wind energy resource potential on
  Tribal land and projected cost savings through a
  blend of wind and hydropower over a 30-year
  period
• Determine seasonal capacity needs and associated
  transmission upgrades for integration of tribal
  wind generation and identify costs associated
  with these activities.
• Incorporate, to the extent appropriate, the
  results of the Dakotas Wind Transmission study
  prepared by Western

Section 2606 continued

• The study report shall
• Provide an analysis and comparison of the
  potential energy cost or benefits to the
  customers of Western through the use of combined
  wind and hydropower.
• Include an economic and engineering evaluation of
  whether a combined wind and hydropower system can
  reduce reservoir fluctuation, enhance efficient
  and reliable energy production, and provide
  Missouri River management flexibility.
• Include a feasibility determination and
  recommendation for a demonstration project to be
  carried out by Western, in partnership with an
  Indian Tribal government or tribal energy
  resource development organization, and Western
  customers to demonstrate the feasibility and
  potential of using wind energy produced on Indian
  land to supply firming energy to Western,
  including
• The economic and environmental costs of, or
  benefits to be realized through, a
  Federal-tribal-customer partnership.
• The manner in which Federal-tribal-customer
  partnership could contribute to the energy
  security of the United States.

• How much and where
• Operational Integration
• What will it take to utilize the energy
• What challenges will be presented
• Economics
• What are the costs and the benefits resulting
  from wind/hydropower integration
