Wind Resource Assessments

Lummi Nation Wind Energy Development Feasibility Assessment Services RFP


The Lummi Nation is requesting proposals from qualified consulting firms to provide wind energy development feasibility assessment services. The overall goal of the Lummi Indian Reservation Wind Energy Development Feasibility Assessment Project, which is funded through a grant from the U.S. Department of Energy, is to determine if and at what cost wind energy development on the Reservation can help achieve the tribal goal of energy self-sufficiency.

Wind power assessments developed by the National Renewable Energy Laboratory (NREL 2002) indicate that the large tideland and floodplain areas of the Lummi Indian Reservation (Reservation) are in Wind Power Class 3, having Fair wind power potential at 50 meters. Although the available mapping and general observations indicate that wind power generation is feasible on the Reservation, site-specific wind measurements are needed to ensure a reasonable economic return prior to making the substantial capital investments associated with installing wind turbines and associated transmission infrastructure. Numerous other factors, such as cultural, socio-economic, natural resources, noise, aesthetics, and adjacent land uses also affect the feasibility of a wind energy project on the Reservation.

Please contact Monika Lange for further information. Women and/or minority owned businesses are encouraged to apply. All proposals must be received by 12:00 p.m. on July 23, 2010.

Wind Resource Maps and Estimates Show Increased Potential for United States

The National Renewable Energy Laboratory (NREL) and consulting firm AWS Truewind, LLC have developed new wind resource maps and wind potential tables for the United States, the first comprehensive update of wind energy potential since 1993. The analysis indicates that wind resources in the U.S. are greater than previous estimates, up to three times more than previous estimates with the potential to generate up to 37 million gigawatt hours annually.

U.S. Wind Resource Map

Accurate information about the wind resource and the wind energy potential in each state is required for federal and state policy initiatives that will expand the use of wind energy in the United States. For planning installations of wind turbines and development of wind farms, it's important to know if the wind resource for a location is adequate. From wind resource maps, it can be determined if an area of interest should be further explored.

Areas with annual average wind speeds around 6.5 m/s and greater at 80-m height are generally considered to have suitable wind resource for wind development. NREL has conducted a preliminary review and validation of the AWS Truewind's 80-m map estimates for 19 selected states (6 Western states, 6 Midwestern states, and 7 Eastern states) based on tower measurements at heights of about 50 m and above from more than 300 locations.

Wind potential tables, graphs, and maps are available for the contiguous United States and for each state. NREL also produced graphs showing the wind resource potential above a given gross capacity factor at both 80-m and 100-m heights.
