Despite bogus studies and the opinions of wind industry shills, here is some of the ignored proof that repowering Altamont with much larger turbines has resulted in more eagle fatalities. Keep in mind that this total could be higher because wind employees do pick up carcasses and not all eagle fatalities are reported.
Forget all the estimates and the "smoke and mirrors" data acquired by this industry's hired fake experts. Below are the actual eagle carcass counts from the first studies conducted around these much larger turbines. These two repowering projects at Altamont represent 58.46 MW of power and they produced 5 reported eagle carcasses. In sharp contrast the five year study conducted by Smallwood produced an average of about 11 eagle carcasses per year. The 11 eagle carcasses represent an eagle mortality carcass rate of .019 per MW with the total 580 MW footprint and the 5400 small turbines in service at that time.
With the 58.46 MW footprint of the two projects shown below, the 5 reported eagle carcasses show an eagle mortality rate of .0855 per MW. This actual eagle carcass rate is 4.5 times higher per MW when compared to the small turbines Smallwood studied between1998-2003. This increase in eagles killed per MW is also consistent with the large increase of eagle carcasses from Altamont being reported by the FWS over the last several years.
The Diablo Winds Energy Project
The Diablo Winds Energy Project is located in Alameda County California. The project was completed in February 2005 and consists of 31 Vestas V47 turbines (660 kW) located on the Elworthy property in the central portion of the Altamont Pass Wind Resource Area. Together the Diablo turbines represent 20.46 MW.
Two actual Eagle fatalities were reported from the Diablo turbines in the first 1 year study.
"Bird Casualty Finds
Bird fatalities found between March 2005 and February 2006 are listed in Appendix A. This list
includes fatalities observed on standardized search plots and other fatalities that were not
observed on standardized search plots (WRRS and incidental finds). Between 7 March 2005 and
22 February 2006, 16 avian fatalities were found and are plotted in Figure 2. Of the 16, 4 were
reported by Diablo Winds maintenance personnel incidentally through the WRRS reporting
program. Seven raptors were found (5 red-tailed hawks, 1 golden eagle, 1 burrowing owl), with
3 raptors reported by Diablo Winds through the WRRS. Two red-tailed hawk fatalities were
found incidentally by Diablo Winds personnel on the same day very close to one another. An
injured golden eagle was found on the site near turbine 13. According to the veterinarian report, the eagle was missing a wing, the bird was very thin, and the exposed humerus bone was dead, suggesting the collision had not occurred recently."
Buena Vista (38 MW project)
"In 2005, Buena Vista, LLC (BV LLC), a subsidiary of Babcock & Brown, obtained a permit
from Contra Costa County to repower Buena Vista by removing 179 existing 150- and 160
kilowatt wind turbines and replacing them with 38 new 1-megawatt (MW) turbines constructed
by Mitsubishi Power Systems. Construction was initiated in 2005 and the newly repowered wind
farm became operational in December 2006."
At Buena vista 3 golden eagle carcasses were found in just a 6 month period between 7/24/08 and 1/4/09.
