This letter was sent to the Minnesota Public Utilities Commission in reference to the Goodhue Wind project proposal now known as the New Era Wind Farm. New Era explains that it has initiated discussions to assign its power contracts to a third-party wind project developer and site. It further requests that any further evidentiary procedures with respect to the the project before the PUC be placed on hold. It appears from the letter that the project will be sold or canceled.

In late February 2009 the Minnesota Department of Health (MDH) received a request from the Office of Energy Security (OES) in the Minnesota Department of Commerce, for a “white paper” evaluating possible health effects associated with low frequency vibrations and sound arising from large wind energy conversion systems (LWECS). MDH agreed to evaluate health impacts from wind turbine noise and low frequency vibrations. In discussion with OES, MDH also proposed to examine experiences and policies of other states and countries. Below are the Introduction and Conclusions of the white paper released in May 2009. The full report can be accessed by clicking on the link at the bottom of this page.

AN ORDINANCE ESTABLISHING A 90-DAY MORATORIUM WITHIN THE CITY OF FERGUS FALLS ON THE CONSTRUCTION OF WIND ENERGY CONVERSION SYSTEMS (WECS), THEREBY AMENDING CHAPTER 7 ENTITLED ZONING AND SUBDIVIDING, BY ADDING A NEW SECTION 7.43 FOR THAT PURPOSE; AND, BY ADDING BY REFERENCE, CITY CODE CHAPTER 1 AND SECTION 7.99 WHICH, AMONG OTHER THINGS CONTAIN PENALTY PROVISIONS.

At its August 23, 2007 meeting, the Minnesota Public Utilities Commission requested that the Department of Commerce's Energy Facility Permitting staff consult with stakeholders and prepare for the Commission's consideration general permit standards and setback recommendations to satisfy the legislative mandate. The PUC issued this order on Jan 11, 2008.

This document includes studies in Maine, Maryland, Minnesota, New Hampshire, New York, Pennsylvania, Vermont, Virginia and West Virginia.

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].
