Xcel Energy has plans to repower the Grand Meadow wind energy facility. The 67 GE 1.5 MW sle turbines will be replaced with the same number of GE 1.6 MW turbines with larger rotor diameters. The plan with costs for decommissioning the older site are available in the document that can be downloaded from this page. An excerpt of this document is provided below.

This letter filed with the Minnesota PUC confirms Flat Hill Windpark I, LLC's desire for revocation of its permit to construct a 201 MW wind energy facility n Clay County, MN. The content of the letter is provided below and can also be accessed by clicking the links on this page.
The Minnesota Public Utilities Commission (Commission) issued EcoHarmony West Wind LLC Site Permit on February 3, 2010 to construct a 58-turbine, 116-megawatts project. On April 22, 2013, the Site Permit was amended to allow an additional two years to commence construction and obtain a power purchase agreement (or other enforceable mechanism). Failing to do so, Gamesa filed notice that it would not be pursuing the project. The content of Gamesa's notice is provided below. Both Gamesa's letter and the May 8, 2015 letter by the Commission inquiring about the project's status can be accessed by clicking the links on this page.
Geronimo Wind Energy's proposed Paynesville Wind farm was issued a site permit and a Certificate of Need (CN) from the Minnesota Public Utilities Commission on January 26, 2011. The project would consist of 63 wind turbines totaling 95 megawatts to be located on approximately 15,000 acres in Stearns County, Minnesota. Paynesville Wind has been unable to secure a buyer for its energy. This letter was issued by the company this month. The content of the letter is provided below. The original can be accessed by clicking the links on this page.
In this letter to the Minnesota PUC, New Era Wind Farm LLC told the commission that it "no longer intends to develop a wind energy project in Goodhue County" and asked the commission to close all pending matters related to the project.
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 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. .
