Yesterday, Xcel Energy announced it would be seeking a massive 21.2 percent price increase on electricity over the next three years, meaning Xcel residential electricity customers will pay an additional $222 per year, according to the utility filing at the Public Utilities Commission (PUC).
The new rate case would be Xcel's second multi-year rate case since the state legislature allowed them in 2015. In 2017, the PUC approved a four-year rate deal for Xcel Energy that raised residential rates by 10.6%. That deal was retroactive to 2016, and it followed five consecutive years of rate hikes for Xcel. In both 2019 and 2020, Xcel proposed new three-year rate plans, with the last one calling for a total of $597 million in new revenue.
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.
In June, state utility regulators who must approve the project made it clear they weren't satisfied with Big Bend's plans to locate turbines as close as 5.2 miles from the petroglyphs. The historical society and the Sioux bands wanted at least an 8-mile buffer. Apex Clean Energy, Big Bend's developer, revised the project so that all but two of the 50-plus turbines would be at least 7 miles from the petroglyphs.
The Jeffers Petroglyphs site in southwestern Minnesota is sacred to Indigenous people. A wind farm and solar project would diminish the integrity of its “historic and sacred features,” the Minnesota Historical Society argues. ...After hearing the complaints, Apex moved the wind turbines nearest to the petroglyphs from just over 2 miles to 5.2 miles away. But the historical society and the tribes want an 8-mile buffer, and they object to Apex's decision to significantly raise the height of the turbines along with the move.
Plan is rebuilding 5 wind farms to be more efficient.
"The project withdrew from its original point of interconnection due to unusually high transmission upgrade fees that were being imposed by the regional grid operator," said a spokesperson for NextEra Energy Resources.
What started with just a few wind turbines 20 years ago, now turns out nearly 20% of Minnesota’s electricity. But the towering blades haven’t come without questions and controversy in rural Minnesota.
According to utility documents filed by Xcel Energy for it’s Nobles Wind facility, it will cost approximately $445,000 (in 2009 dollars) per turbine to decommission the wind facility. This means it would cost $532,000 per turbine (in 2019 dollars) for each of the 134 turbines in operation at this facility, bringing the total cost of decommissioning the Nobles project to $71 million.
Wind generation through June of 2019 was actually 4 percent lower than through June of 2018, according to Energy Information Administration data. This decline in output comes even though there are more turbines in operation today than there were at this time in 2018.
The wind energy industry isn't immune to cyclical replacement, with turbine blades needing to be replaced after a decade or two in use. That has wind energy producers looking for places to accept the blades on their turbines that need to be replaced.
After a two-year fight, a new wind farm has finally been given the green light in southern Minnesota. But in Freeborn County, hundreds of neighbors are making some noise about it.
Wind speeds were less than forecast on those days, meaning power production was less than expected. Ice on turbines hampered wind production. ...Wind turbines are often programmed to shut down when the thermometer is 20 below to 25 below because equipment can be damaged if turbines continue running. Xcel receives 21 percent of its generation from wind in Minnesota and the Dakotas, and its turbines automatically shut down around 20 below. They were generally down during the nights of Jan. 29 and 30.
The Laborers’ union, representing several construction unions, asserted that the socio-economic benefits of Bitter Root would be “substantially diminished” by a lack of Minnesota workers. RES has used nonunion trades workers on other wind farms in Minnesota, and the Laborers’ union says those workers were mostly from out of state. The Minnesota Public Utilities Commission (PUC) decided the unions’ claims need a closer look.
The Freeborn project marks the first "contested case" over a wind farm before the PUC, prompting the appointment of an administrative law judge to sort out the facts and make recommendations. The judge's ruling isn't binding on the PUC, but such recommendations often carry weight with the commission. ...Invenergy filed a proposal with the PUC that would include noise allowances of no more than 3 decibels above the standard.
The Minnesota Pollution Control Agency (MPCA) said the state's limit for wind-farm noise applies not only to sounds from turbines but also should include background noise such as road traffic, said the filing with the Minnesota Public Utilities Commission (PUC).
The attempt by a London, England, company to build a wind farm in Yellow Medicine County is meeting resistance from a small community just across the South Dakota border ...The request is that RES and the MPUC respect and honor the ordinance that requires wind tower setbacks to be at least 3 miles away from the water.
Expiring tax credits and pushback from opposition groups pose barriers for the wind power in Minnesota, but the industry shows no signs of slowing down in the breezy southwestern part of the state.
WILMONT — Nobles 2 is sailing along smoothly.
State agencies, in their rush to site wind, have dropped the ball — they have failed in their charge to regulate and protect the public and the public interest. We need a respectful siting process, and that is 20 years overdue.
