- Description
- BACKGROUND Wind speed measurements are critical to validating 100-meter wind resources; developing wind plant power curves for use in integration studies; improving wind power forecasting; validating, calibrating and improving mesoscale models for use in integration studies; and understanding micro-effects in wind plants. The high resolution state wind maps produced under the aegis of NREL and others since 1999 have greatly facilitated wind energy development in the United States. By highlighting the areas most likely to have a good wind resource the wind maps have helped focus wind energy development efforts and inform public policy related to wind energy development. For historical reasons the wind maps developed to date are referenced at 50 meters above ground level (AGL). Back in the late 1990s 50 meters was a common hub height for utility scale wind turbines. Thus the maps provided the most accurate information available at the most useful height. In recent years utility scale wind turbine hub heights have increased to 80-100 meters. Recent wind resource assessment research indicates that the wind resource at 80-100 meters often differs markedly from what simple extrapolation from 50 meters would indicate. A new set of wind maps is required that show the wind resource at 80-100 meters to enable continued identification of good wind resource areas. This is especially important in areas such as the Great Lakes region where the modest wind resource at 50 meters AGL has, until recently, generally precluded large scale wind energy projects. Wind development in regions such as this can help reduce the new transmission needed to achieve the US Department of Energy’s 20% Wind Scenario. These new wind maps in turn require good data at 80 m, 100 m and above. Both wind power forecasting and meso-scale modeling for integration studies typically rely on single wind speed location to estimate the power output from wind plants that include many turbines. These “wind plant power curves” are often terrain dependent and not well understood. Through this Sources Sought notice, NREL is seeking organizations with tall tower wind time series data sets for use in validating meso-scale models and validating wind farm power curves. This notice seeks sources that can provide data sets that focus on wind speed measurements to help validate 100-meter wind maps in the Great Lakes region and the development of wind plant power curves, but wind measurements that may help the mesoscale modeling process and NREL’s understanding of micro-effects will also be considered. Interested companies are encouraged to respond to this announcement as soon as possible with complete response information. Responses should include: • Name and address of the company • Point of contact including name, title, phone and email address • Description of the data sets that currently meet the requirements (general location, speed sensor height(s), monitoring period.) QUALIFICATION REQUIREMENTS The offered wind data sets must have the following characteristics: 1. The data set must include data taken at a minimum of 70m AGL 2. The data set must include data for at least 9 months 3. The data averaging interval must be 10 minutes or less 4. Minimum sampling interval is 5 seconds (0.2 Hz) 5. The data must contain the actual measurements. It may not include interpolated or fill-in data 6. At a minimum the data must include wind speed, wind speed standard deviation, and wind direction. Wind direction is required for at least one level. 7.Preferred geographic regions are: a. Great Lakes (especially in or near OH, IN, MI, WI) b. Locations within 10 km of selected wind farms. The list of wind farms are to be determined. 8. The following site information must be included with the data set. a. Location (latitude, longitude, elevation) b. Topo map (1:24,000 or greater resolution) showing the station location c. Description of the terrain & cover around the site d. History of the site during monitoring: For example, was a wind farm installed part way during monitoring. e. Tower description and dimensions f. Photo of the tower 9. The following configuration information must be provided with the data set a.Sensor height b.Sensor orientation and length of the booms c.Sensor make & model dSensor calibration history NREL will consider SODAR and LIDAR data even if it does not strictly meet all the qualification requirements. THIS IS A SOURCES SOUGHT NOTICE, NOT A REQUEST FOR PROPOSAL. VERBAL REPLIES WILL NOT BE ACCEPTED. ALL INQUIRIES MUST BE IN WRITING (HARD COPY OR E-MAIL). Any organizations interested in working with NREL to provide the data described within this document should mail a list of qualifications, based on the qualification requirements listed above, to the National Renewable Energy Laboratory, ATTN: Neil Wikstrom, 1617 Cole Boulevard - MS 3811, Golden, CO 80401-3393. Telephone calls will not be accepted; however, submittals by e-mail are encouraged and should be sent to: neil_wikstrom@nrel.gov. The list of qualifications will be responsive to the items listed above. Responses to this notice, whether mailed hardcopy or electronically, must be received by 3:00 p.m. MDT, February 23, 2009.
