Rand: Critique of Noise Impact Report for NextEra's Golden West Wind Energy Center

Rand_review_epsilon-4177-goldenwest-170321_thumb NextEra's Golden West Wind Energy Center sited in El Paso County, Colorado was required under the County permit to conduct a noise impact study after the project was placed in service in October 2015. Acoustician Robert Rand was asked by residents living near the turbines to review the noise impact study as prepared by NextEra consultant, Epsilon Associates. Mr. Rand's report, included here, identified several material errors with Epsilon's report and also found that the project appears to be operating outside the noise limits permitted by the County and the State. The Golden West Wind Energy Center consists 145 1.72-megawatt GE turbines for a total installed capacity of 249.4-megawatts Mr. Rand's executive summary is provided below.

El Paso County Property Rights Coalition v. El Paso County, NextEra et.al.

15.03.23_epcprc_amend_complt__5bfinal_5d_thumb El Paso County Property Rights Coalition, a Colorado, a Colorado limited cooperative association et. al. filed this complaint against the Colorado County Commissioners of El Pase County and NexEra Energy Resources following the county's approval of the Golden West wind energy facility, a 250 MW project. The project was initially approved by the County in December 2013. Within weeks of the project permit being issued, NextEra Energy acquired the rights of the project and started the process of amending the plans to move the turbines, increase their height and seek permission to raise the transmission line so it was above ground. On January 6, 2015, the Planning Commission considered the amended project and ultimately recommended it be denied by a 6-3 vote.

Minutes: El Paso County Planning Commission votes to deny Golden

Elpaso-pcminutes01-06-2015_thumb These minutes of the El Paso County Planning Commission January 6, 2015 hearing end with the Planning Commission voting to deny recommending approval of the amended Golden West wind energy facility that would site a 250 MW project in the county. Seventy-five people were present in the hearing room to speak either in favor of or in opposition to the project. The final vote was 6-3 to deny the project with the primary reasons for denial being impacts on the health, safety and welfare of the residents, The full minutes for the hearing can be accessed by clicking the links on this page.

How less became more: Wind, power and unintended consequences in the Colorado energy market

This new report from Colorado's natural gas industry says increased use of wind energy indirectly results in raised pollution levels produced by some coal-fired power plants along the Front Range. The report recommends curbing the use of wind energy during the next one or two years to levels that match power output at existing natural gas-fired power plants -- and building more natural gas plants in the long term. The introductory sections of the report are provided below. To access the full document click on the link at the bottom of this page.

Colorado's renewable energy standard: Its impact on the future electric capacity needs of the state

Cef_renewable_white_paper_thumb This paper investigates the impact of the passage of Colorado's expanded Renewable Energy Standard (RES) on the state's energy and generation capacity needs. In September 2006, the Colorado Energy Forum (CEF) issued a report which found that, in order to reliably meet Colorado's anticipated customer electricity needs, 4,900 MW of new electric capacity is required by 2025.

Grid Impacts of Wind Power Variability: Recent Assessments from a Variety of Utilities in the United States

Ewec06gridpaper_thumb In this report we discuss some recent studies that have occurred in the United States since our previous work [2, 3]. The key objectives of these studies were to quantify the physical impacts and costs of wind generation on grid operations and the associated costs. Examples of these costs are (a) committing unneeded generation, (b) allocating more load-following capability to account for wind variability, and (c) allocating more regulation capacity. These are referred to as “ancillary service” costs, and are based on the physical system and operating characteristics and procedures. This topic is covered in more detail by Zavadil et al. [4].
