Death of a Wind Farm
Author: Orr, Isaac; and Rolling, Mitch | Economics, Minnesota
[Summary] The Nobles wind farm has already been repowered after just 12 years in service. Repowering wind projects allows them to requalify for the wind Production Tax Credit (PTC), which expires after the first 10 years of a project’s life [“The primary motivations for partial repowering have been to re-qualify for the PTC” —U.S. Department of Energy (Land-Based Wind Market Report: 2022 Edition). Data from the U.S. Department of Energy shows that the wind facilities repowered in 2021 ranged in . . .

Author: Bessette, Douglas; and Mills, Sarah | Illinois, Indiana, Michigan, Minnesota, Siting
Abstract Utility-scale wind energy is now the largest source of renewable electricity in the US. Wind energy’s continued growth remains contingent upon finding adequate resource potential and transmission capacity, along with communities willing to host turbines. While previous research on the social acceptance of wind has relied predominantly on case studies, resident surveys, and reviews of development practices and strategies, here we use a new method. We use a wind contention survey of energy professionals (n = 46) to assess . . .

Author: Overland, Carol | Minnesota, Noise, Regulations, Technology
Minn. R. 7030.0400 is the MPCA’s noise rule, setting standards for industrial noise. It was developed to limit industrial noise, from a noise source on the ground to a “receptor” on the ground. ISO 9613-2 was also developed to measure ground based noise reaching a ground based receptor. A primary input is the “ground factor” set to address conditions on the ground, the ground effect, between the noise source and the receptor: 7.3 Ground effect (Agr) 7.3.1 General method of . . .

Author: Various | Economics, Michigan, Minnesota
Brian R. Zelenak, Manager, Regulatory Administration, Xcel Energy, February 8, 2011 – re: Nobles Wind Energy Project, Minnesota, 1.5-MW turbines. [download] A conservative estimate for a decommissioning expense is approximately four-hundred forty-five thousand dollars ($445,000) per turbine (2009 dollars).* *Includes allowance for salvage value and based on total dismantling cost estimate for the project of 8.7% of the total plant balance of $510,965,406, equaling an estimated dismantling cost [of] $44.5 million or $445,000 per turbine. [NWW note: The Nobles project consists . . .
