§3506 Wind and hydropower feasibility study

Title 25 › Chapter CHAPTER 37— - INDIAN ENERGY › § 3506

Summary

The Secretary of Energy must work with the Secretary of the Army and the other named Secretary to study the cost and feasibility of a demonstration project. The project would use wind energy from Indian tribes and hydropower from Army Corps dams on the Missouri River to provide firming power to the Western Area Power Administration. The study must check whether blending wind and hydropower is economically and technically practical, compare costs and benefits with current firming power sources, review past and future needs and availability of firming power, estimate tribal wind potential and 30-year cost savings, find seasonal capacity needs and required transmission upgrades and costs, include an independent tribal engineer and a WAPA customer representative on the team, and use the Dakotas Wind Transmission study where appropriate. Not later than 1 year after August 8, 2005, the Secretaries must send a report to Congress with the cost/benefit analysis for WAPA customers, an engineering and economic evaluation of effects on reservoir changes and reliable energy production, recommendations for a demonstration project if feasible (to be run by WAPA with a tribal partner and WAPA customers), and identification of economic and environmental costs or benefits and how a Federal-tribal-customer partnership could help U.S. energy security. Up to $1,000,000 is authorized to carry out the study, available until spent, and costs the Secretary incurs are not reimbursable.

(a)The Secretary of Energy, in coordination with the Secretary of the Army and the Secretary, shall conduct a study of the cost and feasibility of developing a demonstration project that uses wind energy generated by Indian tribes and hydropower generated by the Army Corps of Engineers on the Missouri River to supply firming power to the Western Area Power Administration.
(b)The study shall—
(1)determine the economic and engineering feasibility of blending wind energy and hydropower generated from the Missouri River dams operated by the Army Corps of Engineers, including an assessment of the costs and benefits of blending wind energy and hydropower compared to current sources used for firming power to the Western Area Power Administration;
(2)review historical and projected requirements for, patterns of availability and use of, and reasons for historical patterns concerning the availability of firming power;
(3)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;
(4)determine seasonal capacity needs and associated transmission upgrades for integration of tribal wind generation and identify costs associated with these activities;
(5)include an independent tribal engineer and a Western Area Power Administration customer representative as study team members; and
(6)incorporate, to the extent appropriate, the results of the Dakotas Wind Transmission study prepared by the Western Area Power Administration.
(c)Not later than 1 year after August 8, 2005, the Secretary of Energy, the Secretary, and the Secretary of the Army shall submit to Congress a report that describes the results of the study, including—
(1)an analysis and comparison of the potential energy cost or benefits to the customers of the Western Area Power Administration through the use of combined wind and hydropower;
(2)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;
(3)if found feasible, recommendations for a demonstration project to be carried out by the Western Area Power Administration, in partnership with an Indian tribal government or tribal energy development organization, and Western Area Power Administration customers to demonstrate the feasibility and potential of using wind energy produced on Indian land to supply firming energy to the Western Area Power Administration; and
(4)an identification of—
(A)the economic and environmental costs of, or benefits to be realized through, a Federal-tribal-customer partnership; and
(B)the manner in which a Federal-tribal-customer partnership could contribute to the energy security of the United States.
(d)(1)There is authorized to be appropriated to carry out this section $1,000,000, to remain available until expended.
(2)Costs incurred by the Secretary in carrying out this section shall be nonreimbursable.
