A controversial wind farm project in Calhan was vandalized sometime between Sept. 20 and Oct. 23, according to the El Paso County Sheriff's Office. A single high-powered round was fired into a turbine at the Golden West Wind Energy Center near North Yoder Road and Heaston Road, authorities said.
The proposal, as approved, would have would have "little to no impact on ratepayers" and "includes a more reasonable forecast of natural gas prices and potential customer savings," the PUC wrote in a release.
In its filings with the PUC, Black Hills is asking for the rate increase to cover the costs of a $50 million wind farm and leftover costs from building its $500 million Pueblo Area Generating Station. Some of those costs are high-interest debt that the state Office of Consumer Counsel argues shouldn’t be passed on to Pueblo ratepayers.
A dozen people spoke against the project at the Dec. 19 commission meeting, with concerns related to noise and property values, among other things. ...The project probably will qualify for wind energy production tax credits, he says, by acquiring the farm just before they expired last year.
Wind power company Vestas Wind Systems made its single largest Colorado job cut Thursday, laying off about 200 workers at a Windsor blade plant. The cuts represent 29 percent of the plant's workforce.
Vestas Wind Systems, the wind turbine manufacturer that built four factories in Colorado, announced its third round of job cuts on Tuesday, firing 75 workers at its blade factory in Brighton.
Xcel wants Boulder to pay the wind developer for "curtailment costs" -- these are revenues lost when Xcel has to dump the wind energy because Xcel's load can be met by their coal fired generators and independent generators to which they have contract commitments. Xcel also wants Boulder to pay 100 percent of Xcel's "integration costs" -- these are costs Xcel incurs in managing wind-generated electricity.
The collapse last week of a deal to build a massive electricity-generating wind farm on CSU's Maxwell Ranch highlights the university's struggles to significantly cut its consumption of fossil fuels and reduce carbon dioxide emissions. ...administrators say transforming the university's operations will take far longer than initially expected.
"Cleaner air and cheaper energy" was the slogan when voters mandated wind and other renewable sources for 10 percent of the state's electric generation with Amendment 37 in 2004. Democratic legislators liked the idea so much that they upped the mandate to 20 percent in 2007 and boosted it this year to 30 percent. One small problem: Neither half of the slogan is true.
A 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. ...Cycling operations at coal plants -- ramping them up or down in response to the wind or other issues -- causes them to run less efficiently and also interferes with emissions control equipment.
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.
Thanks to Colorado's renewable portfolio standard, wind power is a "must take" resource for Public Service, meaning the utility must incorporate wind power into the grid even if it means ramping down a coal-fired plant. Now, Gov. Ritter and Democrats in Denver want to increase the renewable portfolio standard by 50 percent through House Bill 1001, without considering the consequences for Denver's air quality. Despite the $2 billion worth of new wind turbines installed since 2004, Denver's air quality has not improved.
Vail Resorts Inc. said Monday it will not renew its three-year commitment to purchase wind-energy offset credits. ..."going forward, we intend to channel our efforts on more comprehensive projects, which help protect the climate and also offer habitat and watershed benefits to local communities, such as the Hayman Restoration Project," Katz said.
Bats, not birds, might be more at risk from a wind tower at the top of the Snowmass ski area, according to a local forest service official. The blades of three potential turbines the Aspen Skiing Co. and the Forest Service are considering placing up from the Big Burn chairlift could be more deadly to bats if the agencies are required to place a light on the tower for aviation purposes, according to Jim Stark, winter recreation supervisor for the White River National Forest. The light could attract insects and therefore bats, he said.
Clean and Green is one of many brokers in the United States selling renewable energy credits, or RECs, which allow customers with no direct access to wind power to buy the environmental benefits of renewable energy produced elsewhere. But at the end of last year, the Boulder-based company dropped its nationally recognized certification that lets customers know they're actually getting what they're buying. ...Clean and Green has no problem with the certification program, Executive Director Gerry Dameron said, but couldn't justify the cost anymore. "We called Green-e and said, 'Look, we appreciate what you guys do, and we'd love to be Green-e certified in the future, but we can't afford all the fees," he said. "We can't afford to spend $6,000 a year. Our company has never made a profit, and I've never drawn a salary, not one dime."
While there are some small hydroelectric generation projects in Colorado, the bulk of renewable energy is provided by wind turbines. Under the law, solar electric is required to meet at least 4 percent of the renewable energy for investor-owned utilities. "The problem is, the wind doesn't blow all the time and the sun doesn't shine all the time," said Gary Schmitz, chief economist for the Energy Forum. "The purpose of the study was to look at how many of these will we have to build to get that amount of energy." The answer is somewhere between 1,700 and 2,000 more wind turbines that produce between 1.5 and 2 megawatts each, or roughly five times current numbers. Solar capacity would have to increase about sixfold from current levels. Power providers say they can reach those levels without much economic disruption, although requiring larger amounts of renewable energy would begin to strain financial resources, Smith said.
Xcel's voluntary wind power customers in Colorado will be hit with higher bills beginning next year. But regular customers will benefit from lower electric bills, according to Xcel filings with regulators late Tuesday. The utility says fully subscribed customers of WindSource will have to pay higher premiums - about $13 more per month compared with regular customers - because they aren't benefiting from declining natural gas prices enjoyed by regular customers. Fully subscribed customers get all their electricity from wind power. Also, savings from wind power seen in past years, when wind farms were replacing old and costly natural gas-fired power plants, are declining as wind farms are replacing newer and more efficient power plants. ...However, wind industry advocates said the current lower price of coal and natural gas does not reflect their true price. Also, those fuels likely will pay a carbon tax in the near future that would make them a more expensive source of power generation compared to wind, a freely available source.
Rather than enjoying his role as an REC pioneer, Schendler felt increasingly anxious. In private, he pushed REC brokers for hard evidence that new wind capacity was being built. Their evasiveness gnawed at him. ...The trouble stems from the basic economics of RECs. Credits purchased at $2 a megawatt hour, the price Aspen Skiing and many other corporations pay, logically can't have much effect. Wind developers receive about $51 per megawatt hour for the electricity they sell to utilities. They get another $20 in federal tax breaks, and the equivalent of up to $20 more in accelerated depreciation of their capital equipment. Even many wind-power developers that stand to profit from RECs concede that producers making $91 a megawatt hour aren't going to expand production for another $2. "At this price, they're not very meaningful for the developer," says John Calaway, chief development officer for U.S. wind power at Babcock & Brown ..."It doesn't support building something that wouldn't otherwise be built."
Because of wind variability, there is no way of predicting exactly how much energy the wind turbines will produce at a specific time on any given day. Xcel Energy spokesman Tom Henley at the Denver office said Xcel adjusts for this variability with its Heat Rate Exchange Program, a centrally located part of the company's computer system. The program reads the input from Xcel's various power generating plants, from wind farms to coal- , gas- and water-powered plants. When the wind farms are going strong, the computer system will cause the most expensive power source to "back down." This will probably be one or more of Xcel's gas-fired power plants, Henley said. Coal-fired plants, such as the Pawnee Power Plant at Brush, won't be turned down. They are cheaper to operate than gas-fired plants, and also would take longer to get fired back up to full power when the input from the wind farms dropped. A gas-powered plant can be fired back up in as little as half an hour, Henley said.
Permitting for the 550-megawatt gas-fired plant southeast of Fountain is underway, and officials with Invenergy, the company that wants to build the plant, hope construction begins in May with completion in 2009. The company will meet with environmentalists on Wednesday to discuss the plant. The Squirrel Creek Power plant would be able to augment energy from wind generation plants in eastern Colorado, said Doug Carter, vice president of development for Invenergy. “Once you get a plant like this, you can bring in more wind power,” Carter said. “When the wind is blowing, you can back the plant down. When it’s not, you can fire it up.”
