The proposed tidal barrage, subject of a £60,000-£100,000 feasibility study commissioned by Scottish Enterprise, the Nuclear Decommissioning Authority (NDA) and Northwest Regional Development Agency (NRDA), would stretch over the River Solway from Annan in Dumfries & Galloway to Bowness-on-Solway in Cumbria. http://www.windaction.org/articles/21665 http://www.windaction.org/articles/20954 Mon, 27 Apr 2009 13:37:14 GMT The Obama administration wants to rebuild the national electric grid that delivers power to everyone's toasters and televisions. One reason is that the grid can't handle all the new solar and wind power the president wants to build to create a greener energy economy. Here's the problem: Solar and wind power are intermittent. Sometimes it's sunny, sometimes it's not, and it's the same for wind. But the grid needs constant and reliable sources of power. http://www.windaction.org/articles/20954 http://www.windaction.org/articles/16172 Tue, 03 Jun 2008 22:26:09 GMT The U.S. Department of Energy (DOE) has created a collaboration with the six leading wind turbine makers to promote advanced research and development. ...The agreement builds on the recently released DOE report '20 Percent Wind Energy in 2030' that examines the technical feasibility of harnessing wind power to provide up to 20% of the nation's total electricity needs by 2030. http://www.windaction.org/articles/16172 http://www.windaction.org/articles/14870 Thu, 27 Mar 2008 08:12:33 GMT But state officials do not have a clear picture on how readily the state's electricity transmission infrastructure could accommodate the added load - a proposed 2,500 megawatts in the Lower Peninsula and 520 in the UP - from new wind-generating sources. A 2006 report from MPSC found that barring "significant enhancements," existing electric generation and transmission capacity would be insufficient to meet reliability standards in the Lower Peninsula by 2009. The MPSC is working on a study with transmission-owning companies to determine the cost of updating Michigan's transmission system. "If we do this smart, and that's a big leap of faith right there, where we see the wind being developed is where they need to build transmission anyway," said Joseph Welch, president and CEO of Novi-based ITC Holdings Corp. http://www.windaction.org/articles/14870 http://www.windaction.org/articles/14853 Wed, 26 Mar 2008 15:15:27 GMT Wind 2008 -- the not so good news -- The Energy Reliability Council of Texas (ERCOT) is the independent system operator that manages the region's grid with oversight by the Public Utility Commission of Texas (PUCT). As SGN reported in March 2008 (see Smart Grid News article link below), ERCOT operators had to react promptly on February 26 to balance load through demand response (DR) because of system reliability problems caused by wind intermittency. But systems reliability was not the only issue caught in the headlights by this event. The Wall Street Journal also spotlighted the economic impact; namely that the unexpected loss of wind generation caused wholesale power prices to soar from $299 per MWH to $1,055 per MWH in West Texas. http://www.windaction.org/articles/14853 http://www.windaction.org/articles/14583 Sun, 09 Mar 2008 21:04:02 GMT State and regional regulators acknowledge the hurdles - especially in northern New Hampshire - but don't have ready solutions. A bill before the New Hampshire Senate would have the state be ready to act if no regional solution is forthcoming. ISO New England, which manages power for the region, is considering changing rules so more of the costs of transmission upgrades could be shared regionally. But as things stand now, backers of projects generally must pay for upgrades needed to connect them to the system. "None of this is a real speedy process," acknowledges Michael Harrington, senior regional policy adviser for the state Public Utilities Commission. http://www.windaction.org/articles/14583 http://www.windaction.org/articles/14560 Sat, 08 Mar 2008 14:55:15 GMT A physics argument broke out at Friday's hearing on the Bluewater Wind contract. When a wind farm powers up, which plants power down? Bluewater Wind officials said Friday that in the congested Delmarva Peninsula, it will be area fossil-fuel plants. Area residents will realize a direct environmental and health benefit, they said. But Delmarva Power officials said the benefits will be diluted throughout the 13-state PJM electrical grid, and would have its biggest impact on oil-burning plants, not generators that use the notoriously dirty-burning coal. ...Citing a PJM Interconnection official who spoke at the hearings, they contended environmental benefits of an offshore wind farm would be spread throughout the grid. It wouldn't be coal that would go first, but more-expensive fossil fuels such as oil, said company spokesman Bill Yingling. http://www.windaction.org/articles/14560 http://www.windaction.org/articles/14512 Wed, 05 Mar 2008 23:03:04 GMT While the US Department of Energy has spent $57.5 billion over the past 30 years for research & development on advanced energy technologies such as Ethanol, solar and wind power the nation's energy usage has not dramatically changed-fossil fuels today provide 85% of the nation's energy compared to 93% in 1973. Many technical, cost and environmental challenges must be overcome in developing and demonstrating advanced technologies before they can be deployed in the US with greater impact. Those were just some of the not-too-encouraging conclusions the Government Accounting Office told the Subcommittee on Energy and Environment, Committee on Science and Technology today. ...· Wind technologies: DOE is assessing its long-term vision of generating 20% of the nation's electricity using wind energy by 2030. Its current R&D efforts, however, are focused on more immediate expansion of the wind industry, particularly on utility-scale wind turbines. One of DOE's targets is to increase the number of distributed wind turbines deployed in the United States from 2,400 in 2007 to 12,000 in 2015. Although wind energy has grown in recent years, from about 1,800 megawatts in 1996 to over 16,800 megawatts in 2007, the wind industry still faces investors' concerns about high up-front capital costs, including connecting the wind farms to the power transmission grid, the GAO said. http://www.windaction.org/articles/14512 http://www.windaction.org/articles/14171 Sat, 16 Feb 2008 23:05:47 GMT Driven by soaring energy demands, the high cost of gas and oil and worries about global warming, an expansion of peaceful nuclear power increasingly appears to be inevitable. "I believe very strongly that new nuclear plants will be built in the U.S. in the coming decades to address problems with respect to higher energy demand, high prices and global warming," said Sudarshan Loyalka, a professor of nuclear engineering at the University of Missouri-Columbia. "I believe the nation has no other choice." http://www.windaction.org/articles/14171 http://www.windaction.org/articles/13989 Wed, 06 Feb 2008 21:23:27 GMT GWEC figures wind power's capacity in 2005 was about 24%-that is, wind turbines spin 1 hour out of 4, year-round. That will improve, but slowly. Bigger and taller turbines, in more favorable locations-especially offshore-will make wind turbines more efficient. But it will be a long time before wind power's paper strength starts to be reflected in real electricity generation. GWEC's own figures point to wind power creeping toward 30% efficiency over the next twenty years. Wind power may be the most mature horse in the renewable-energy stable. But even a thoroughbred is going to have a tough time catching up with the supertanker that is the fossil-fueled energy establishment. http://www.windaction.org/articles/13989 http://www.windaction.org/articles/12938 Thu, 29 Nov 2007 23:26:45 GMT Consumers Energy plans to develop as many as eight windmill farms in Michigan, officials say. The move is part of the utility's Balanced Energy Initiative, which aims in part to double the amount of renewable energy the company generates from 5 percent to 10 percent by 2015. ...''We need to add 3 million megawatt hours per year ... to go to 10 percent by 2015,'' Rasher said. For the wind farms, Consumers is looking at installing large turbines that generate up to 2.5 megawatts each. Each wind development will generate up to 100 megawatts. But Rasher said the wind farms can only be expected to generate power about 25 percent of the time. That's why Consumers also is planning to build an 800-megawatt coal-fired plant at its Karn-Weadock complex in Bay County's Hampton Township. ''We need some other resource that's dispatchable,'' Rasher said. ''You can't put all your eggs in one basket.'' http://www.windaction.org/articles/12938 http://www.windaction.org/articles/12624 Sun, 11 Nov 2007 22:31:24 GMT George Gantz, a Unitil vice president, unveiled some company dreams this past week to reinvent the big regulated utility. He told Rep. Naida Kaen, D-Lee, and other stakeholders for "distributed energy" that Unitil would like to work itself out of business as a traditional energy retailer. Distributed energy, a new buzz word, is made by small generators scattered across the electric grid, often remote from the big power plants. ...Under existing law, that would be like McDonald's buying burgers from its patrons. But everybody would win if Unitil could claim the renewable energy credits a business or homeowner can earn under a new state law also sponsored by Fuller Clark. It rewards sustainable energy sources. http://www.windaction.org/articles/12624 http://www.windaction.org/articles/12530 Tue, 06 Nov 2007 16:42:08 GMT A year after a bitter congressional fight over offshore drilling for oil and gas, the Bush administration now wants to tap the ocean's winds, waves and currents as a source for alternative energy. This time, though, environmental interests are likely allies, not vocal opponents. ...The federal government will entertain bids beginning this week for companies to put testing equipment like meteorological towers in the ocean waters to gather data on wind, wave or current energy. http://www.windaction.org/articles/12530 http://www.windaction.org/articles/12496 Sun, 04 Nov 2007 01:35:35 GMT For $50,000, Oklahoma can get the same kind of comprehensive study Kansas got from Southwest Power Pool on the state's wind power resource. The plan could be finished by spring 2008 and would provide the guidance state leaders need to form a plan for new electricity generation and transmission upgrades. ...Bary K. Warren, director of transmission policy and compliance for the Empire District Electric Co. in Joplin, Mo., cautioned the group to keep projections for future wind generation development modest. Companies may put out press releases indicating their intent to build future capacity, but unforeseen developments may significantly limit the amount of wind generation that actually gets built, he said. http://www.windaction.org/articles/12496 http://www.windaction.org/articles/12371 Fri, 26 Oct 2007 17:53:42 GMT Several new North Country energy projects are in the works, but questions remain on how to transmit to homes and businesses the power they would generate. Experts at an ad hoc energy stakeholders meeting held Oct. 16 at the State House in Concord generally agreed that construction on several proposed wind farms and wood-fired power plants in Coos County will take three to four years - and perhaps longer if New Hampshire hopes to convince other New England states to cover 90 percent of the costs. ...Donna Gamache of PSNH said the hard part is guessing which players are serious and have the stamina to wait out the regulatory approval process. She said what she called "the California model" would may be "the easiest way to absorb the risk." In California, a regional electric grid underwrote the cost to transmit new solar and geothermal power to the populated coast in the hopes that future developers would pay their share as they hooked into the lines. If PSNH tackles a project like that without state help, experts fear ratepayers would eat the stranded costs if too few plants came on line. http://www.windaction.org/articles/12371 http://www.windaction.org/articles/12337 Tue, 23 Oct 2007 22:46:27 GMT Why is Kansas behind? The short answer: It's complicated, and thoughtful people disagree. Wind proponents say the state has provided little leadership, either through regulation or incentive. State officials say Kansas has been perceived as being anti-wind, which has encouraged citizens opposed to wind. Utilities insist they're embracing wind just as fast as they can. ...Many utilities maintain that adding any significant quantity of wind-powered generation will make the electric grid too unstable, because you never know when the wind will start blowing. Or stop. ..."They [wind turbines] could never, ever serve even one home," he said. That's because at some point the wind will stop but demand for electricity hasn't. ...in order to make this wind power available, Austin Energy had to line up a back-up source of electricity for nearly all its wind energy. The Electric Reliability Council of Texas, which operates the electric grid in much of Texas, requires all utilities file an energy plan, every day, that shows how much electricity it expects its customers to use during every 15-minute period of the next day, and where it plans to get that power from. The 9 percent rule If the power source is a wind farm, the Electric Reliability Council of Texas counts only 8.7 percent of the farm's rated capacity. Never mind wind farms typically produce 20 percent to 40 percent of their rated capacity in the long term. What matters is the short term. http://www.windaction.org/articles/12337 http://www.windaction.org/articles/12305 Mon, 22 Oct 2007 16:54:31 GMT Roxanne Notley, Executive Director of the Aurora Development Corporation feels no decision has been made on wind energy development on the south coast. "We are not totally convinced about wind energy. The reason is because we just don't have enough information to validate our argument. So we used a proactive approach to determine if wind diesel would provide enough wind energy for now and in the future." ..."I did hear some comments from people. Most thought, 'oh my goodness, we are not getting wind power are we.' They are very worried, and scared that this is something that is going to be our alternative," noted Mrs. Notley. The problem with wind and diesel powered generation is that it is not reliable for taking on huge energy loads. http://www.windaction.org/articles/12305 http://www.windaction.org/articles/12304 Mon, 22 Oct 2007 16:45:30 GMT While it is pursuing wind power as a renewable resource -- most recently with a large deal last week -- that source is strictly supplemental, SMMPA spokesman Dan Hayes says. Wind-generated power is available when the wind blows, so it is not always online to ship. SMMPA needs to have enough power available 24/7 to supply its 18 city-owned utility companies and their customers. ...But there are other possibilities for baseline electricity, and SMMPA's chief operating officer, Dave Geschwind, says agency managers now are evaluating them more closely. http://www.windaction.org/articles/12304 http://www.windaction.org/articles/12292 Sun, 21 Oct 2007 12:33:57 GMT Industry leaders believe wind could fill up to 20 percent of generation portfolio. But even wind proponents warn against the notion that it can solve the nation's energy and greenhouse gas concerns. "Wind is a great technology ... But it's not a panacea." There's fossil fuel consumption in the maintenance of wind farms. Many prime wind resources are located far from areas where renewable energy is in demand. Even here at the Foote Creek wind facility, where high gusts wreak havoc on turbines, lightning strikes are equally troublesome. "You've got to look at it for what it is," said Borrows. http://www.windaction.org/articles/12292 http://www.windaction.org/articles/12179 Sun, 14 Oct 2007 02:10:18 GMT ... wind energy farms are not a simple panacea for the country's energy problems. Last week the Beatrice turbines were being serviced but, if they had been operational, they would not have been turning. The North Sea's winds were virtually non-existent, meaning no power would have been generated. Opponents say such variability of output is a drawback of wind energy. But O'Brien insisted: 'If we can build big turbines far away from the shore, they will cause minimum upset and disruption. This is their future and that is why the Beatrice project is so important.' http://www.windaction.org/articles/12179
