Vestas plans to build research and development center in U.S.

A major blade manufacturing plant in east Windsor appears to be only a starting point for global wind-power giant Vestas Wind Systems. The company, based out of Denmark, announced Thursday that it now has intentions to build a research and development center in the United States. "Today, Vestas is a technology enterprise. If we want to be market leaders, we have to be present and drive the development, where the market is. And that is, amongst other places, in the U.S.," said Finn Strom Madsen, president of Vestas Technology R&D in a press release. The center is expected to be operating in 2009 and could employ up to 80 people at full capacity in 2010.

Tyrone Borough forester's report suggests erecting wind farm on watershed property

In 2005, Tyrone Borough Forester, Paul Noll, of Noll's Forestry Services, Inc. wrote the Pennsylvania Forest Stewardship Plan based on the 3,800 acre borough watershed property. Recently, Noll issued a recommendation/ suggestion summary report on the property concerning the possible Gamesa Energy USA wind farm installation and the issues that need to be addressed at the watershed property as a whole. ...In Noll's recent report, he stated that he would be "in favor of having the wind towers erected on the watershed property because you will be disturbing only a small area of the property, but the money you receive from the towers can be used to improve other areas of the watershed property."

Activists, utilities duel over powerlines, again

It's back to the '70s for the south metro, as a new generation of major powerlines is being proposed for rural land -- and activists and farmers begin to meet. ...The companies are seeking state approval for a cluster of major lines. Two of them -- 345-kilovolt lines with towers as high as 150 feet, one stretching 230 miles west to South Dakota and the other 150 miles southward to Wisconsin -- would cross Dakota County. No specific pathway has yet been laid down, but the general outlines of the corridors -- mostly 10 to 12 miles wide -- are clear. Points of controversy are expected to include whether the lines are needed, whether they pose health risks and how much landowners should be paid.

Byron King, with a few notes on geothermal energy...

The utilities of the US, if not those in many other parts of the world, have pressing needs not just to supply power to energy-hungry consumers. But more than that they must meet both public and political pressures for using renewable energy sources. Apparently heedless of the impact to the environment of the Middle Kingdom and abroad, China commissions a new coal-fired plant every 5 days. Yet in the US there has not been a new coal-fired power plant permitted in about a year. So over time in North America, the older systems are passing away. The question is, what will take their place? To the extent that the public envisions renewable energy systems, the image it holds is of tall poles with windmill systems on top with blades turning. Or there is an expectation of solar systems mounted on rooftops, facing the sun. But these are intermittent sources of energy production. Some of the time - most of the time, really - the wind does not blow. And at least in the nighttime, the sun does not shine. So for each Megawatt of power that moves through the grid, down to meet the load, the requirement is for three megawatts of installed capacity of wind and solar. Build three, get one. In the big picture, this is not a good use of resources.

Z4 seeks compressed air energy storage

Kevin Luke of Buford-based Z-4 Energy Systems wants to develop a way to save wind energy for when the wind's not blowing. He's working on a commercialization plan for wind-powered water pumping, incorporating compressed air storage. Luke points out that wind is variable and energy storage is needed to provide controlled, consistent water pumping. He seeks to use air compressors, similar to those found commercially, powered by a wind turbine rotor. The driving force behind his efforts is that the wind blows at variable speeds and when there is not enough wind to turn the turbine, the stored air can continue to be used to pump the well. Currently, wind electric and solar powered systems use lead acid batteries for storage, which don't perform well in the cold weather and have a short lifespan.

Unitil explores nontraditional energy frontier

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.

Wind energy too much of a good thing?

"I currently have, in Minnesota, 23,000 megawatts of interconnection requests for wind," says Moeller, who oversees new connections for MISO. Another 23,000 megawatts of future wind power in North Dakota, South Dakota, Iowa and Wisconsin also is in line. In comparison, the entire Twin Cities metropolitan area typically draws about 6,000 megawatts of electricity out of the transmission system. While some have been on record for years, a sudden barrage of requests -- about 22,000 megawatts' worth -- has burst into MISO since Sept. 10. Minnesota's new renewable energy law, probably triggered some.

A Primer on Wind Energy

As consumers, we pay the full market price for wind-generated electricity plus the value of renewable energy credits mandated by the Legislature. As federal taxpayers, we donate another two cents per kWh, and support the fast depreciation (tax savings) allowed wind installation entrepreneurs. Mars Hill’s units produce 1 percent of Maine’s electricity and 0.01 percent of New England’s. The Kibby Mountain proposal of 44 three-MW units is projected to produce about .37 billion kWh per year. The number of kilowatt-hours supplied by the wind is very small. The combined output from Mars Hill and Kibby Mountain would be about 5 percent of Maine’s or .5 percent of the total New England grid. The real cost of wind energy, if broken out on our electric bill, would be a shock.

European power companies breeze into the U.S. wind farm business

The European Union has taken the lead on many climate change issues - from ratifying the Kyoto Protocol to passing laws to require and encourage the development of renewable energy. Why, then, are so many European energy companies looking to invest in the United States? For António Mexia, the chief executive of Energías de Portugal, the answer is simple. "The United States is the fastest-growing market in the world for wind power," he said. "If we want to be a leader, we have to be here." ..."In America you can put up a 200- or 300-megawatt wind park," Mexia said. "You can't do that in Europe" because of the lack of open space for such large wind farms. There is also more potential for growth in the United States, where wind farms account for barely 1 percent of installed generating capacity. In some EU countries, that figure is as high as 10 percent.

Latest U.S. energy plan: Use power of oceans; federal government exploring ways to tap ocean's wind and water

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.

Officials seek planning guidance in wind power study

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.

Forecasts to power use of wind energy; Latham firm wins contract to predict weather for generators

AWS Truewind, a Latham firm, will forecast winds 48 hours in advance under a two-year contract with the New York Independent System Operator to make it easier for turbine companies to offer more guaranteed power in advance. Forecasting also will make it easier to manage the grid by giving a clearer picture of how much wind power will be coming, which in turn should reduce the amount of power supplied from polluting sources like coal- and oil-fired power plants.

Energy logjams looming

North Dakota's wind-power industry has grown dramatically in recent years and shows signs of continuing the upward trend. However, the industry also faces increasing obstacles in exporting electricity because of transmission bottlenecks. That was a message industry figures made in presentations Wednesday to the Empower North Dakota Commission, a new board that will help steer state energy-development policy, at North Dakota State University.

Okla. utility proposes power line to unlock wind

OGE Energy Corp is prepared to build a new high-voltage transmission line to accelerate development of wind generation in Oklahoma, the utility company chief executive said on Tuesday. Oklahoma City-based OG&E Electric Services said new transmission is needed to unlock the potential for power to flow from future wind farms in the western part of the state to populated cities in the east. Chief Executive Officer Pete Delaney said OG&E, Oklahoma's largest electric utility, plans to significantly increase its wind production from 170 megawatts to 770 MW over the next five years to meet increased customer demand for renewable power.

Getting a Second Wind; Bigger blades boost offshore potential

No renewable energy is growing faster than wind power, and yet those gigantic white turbines-one built every four hours-are churning out less than 1 percent of the nation's electricity. To get to 20 percent-President Bush's aim-production would have to ramp up to one every 15 minutes for 25 years, says Vic Abate, vice president for renewables at General Electric. ...Pricey power. Although offshore wind power is big in Europe, it's not moving so quickly in the United States. Local opposition is often cited, but just as important is that offshore developments cost twice as much as onshore wind. Sure, the East and West coasts have enough wind to power the whole country, but the same could be said of the Great Plains and Texas. "On shore, there's plenty of resource," says Abate, who thinks the next wave of technology will be to try to squeeze more efficiency out of large wind farms and deal with wind's greatest problem-its intermittency.
