Work on wind utility site starting this week

Big machines have been rolling up to Allegheny Mountain for days. Site development work on Virginia's first industrial wind energy plant is expected to start this week. Passersby report heavy equipment has been parked near the entrance to Red Oak Knob, and blasting heard over the last couple of days. A skidder moved in after dark a few days ago, and trees are being cut near one of the turbine sites; one truck full of logs has already headed out with its load.

More than "renewable" energy needed: Microsoft

Efforts should be focused on stopping output of carbon dioxide, the greenhouse gas which helps heat the planet, rather than moving to a source that can be regenerated, said Craig Mundie, the man who replaced Bill Gates as the world's largest software maker's futurist. Conservation and radical technologies, including new nuclear, could be key, he said.

Company plans Wyo. wind farm

A company plans to build a $420 million wind farm with 133 turbines in southwest Campbell County. San Ramon, Calif.-based Third Planet Windpower is eyeing 14,000 acres for the project on both sides of Wyoming Highway 50 near the Johnson County line. The company has begun talking to local landowners about leasing land.

A green challenge: Make renewables reliable

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.

Utility wants to spur transmission access

Electricity distributor NorthWestern Energy is seeking approval from the Federal Energy Regulatory Commission to conduct "open-season" bidding from developers to gain access to two proposed electric transmission lines costing at least $1 billion. The power lines, if approved, could kick start wind farm development in Montana and deliver the renewable electricity produced by wind farms to markets across the West, according to NorthWestern officials. "We want to be the highway," NorthWestern spokeswoman Claudia Rapkoch said.

Lifeline for renewable power

To make use of this clean [renewable] energy, we'll need more transmission lines that can transport power from one region to another and connect energy-­hungry cities with the remote areas where much of our renewable power is likely to be generated. We'll also need far smarter controls throughout the distribution system--technologies that can store extra electricity from wind farms in the batteries of plug-in hybrid cars, for example, or remotely turn power-hungry appliances on and off as the energy supply rises and falls. If these grid upgrades don't happen, new renewable-power projects could be stalled, because they would place unacceptable stresses on existing electrical systems.

Power line projects see opposition

Opposition continues to grow against a high-powered transmission line proposed to run through parts of Gillespie and Kerr counties. A steering committee in Harper and other concerned citizens opposing the private transmission lines have met several times in the past few months and are encouraging landowners to resist leasing utility easements. ...Hilliard Energy is attempting to acquire a series of contiguous 180-foot utility easements for Florida Power and Light Energy to build a private 345 kilovolt line from Taylor County to Comfort.

Company seeks help harnessing power of sun, wind

An Upper Moreland company is seeking a $1 million state grant to develop a combination solar and wind turbine that it is touting as "the world's first hybrid renewable energy technology." Precision Assembly Inc., on the 2300 block of Computer Avenue, is partnering with Bluenergy Solarwind Inc., to develop the turbines, which would harness both wind and solar energy and would be sold to owners of commercial or residential buildings to provide clean energy, according to Paul Stepanoff, the company's chief executive officer.

NCSU will lead energy smart-grid project

N.C. State University was selected by the National Science Foundation to lead a $28.5 million research initiative to transform the nation's century-old power transmission system into a "smart grid" network that will be able to store energy from solar power, wind farms and other alternative resources.

Wind power stored in underground caverns

A New Jersey company said last week that it has joined with Michael Nakhamkin, one of the top thinkers in energy storage, to develop ways to trap wind-generated power in underground reservoirs. Nakhamkin has helped develop technology to pull excess energy off the power grid - usually at night when usage has waned - to run compressors that pump air into sealed, underground caverns that once held oil, salt or natural gas. During periods of higher demand, the air is released and heated to run air expansion turbines. ..."We really think this is a game-changer for the renewables industry," said Roy Daniel, chief executive of Energy Storage and Power LLC, a joint venture between PSEG Energy Holdings and Nakhamkin.

FPL Group profits drop 48 percent; Loss fueled by plunging net income in renewable energy

FPL Group Inc., the largest U.S. producer of wind power, said second-quarter profits fell 48 percent on a drop in the valuation of energy contracts. Its net income declined to $209 million, or 52 cents a share, from $405 million, or $1.01, a year earlier. Revenue fell 8.8 percent to $3.59 billion. FPL Energy, the alternative energy arm of the company, reported a decrease in net income of 98.5 percent to $3 million in the second quarter from $203 million last year. The net income of Florida Power & Light Co., which provides electricity for 4.5 million customers in Florida, increased by 2.8 percent to $217 million from $211 million.

Judge hears Fayette wind turbine debate

Attorneys on different sides of a windmill dispute in Fayette County can agree on at least one aspect of the 262-foot-tall turbines: the hulking structures can't be camouflaged. "A wind turbine can be seen. You can't hide it," said Dan Rullo, attorney for Iberdrola Resources, formerly PPM Energy. ...The project has been on hold since March 11, when the zoning hearing board denied the company's request for a special exception and variances for 24 of the turbines. The matter went before a judge Thursday after Iberdrola filed a civil suit appealing the board's denial.

Indian wind-turbine firm hits turbulence

The grand U.S. ambitions of Indian wind-turbine manufacturer Suzlon Energy Ltd. are facing mounting problems. The Indian company -- the world's fifth-largest wind-turbine maker by sales -- earlier this year acknowledged that 65 giant blades on turbines it had sold in the U.S. Midwest were cracking because of the extreme gusts in the region. The company is reinforcing 1,251 blades, almost the total it has sold in the U.S. Now, other problems are emerging, in part because the company quickly ramped up U.S. sales to meet burgeoning demand for alternative energy. ...

Prattsburgh board rules in favor of eminent domain

The Prattsburgh town board has ruled in favor of eminent domain. The decision means First Wind, the company that wants to build a 36 turbine wind farm in Prattsburgh can now take portions of land from property owners who oppose the project. Eminent domain was proposed after seven property owners said they would not sell their land to the company. First Wind wants the property along the town highways to lay underground cables.

Testing the effectiveness of an experimental acoustic bat deterrent at the Maple Ridge wind farm

2008mapleridgeacousticbatdeterrent_thumb This paper documents the results of an in-field test at the Maple Ridge wind energy facility in New York to determine the effectiveness of using an experimental acoustic bat deterrent to reduce bat mortality. The executive summary excerpted below suggests the results were inconclusive. Most bat experts remain unconvinced that acoustic deterrence will be a suitable mitigation approach to reduce bat fatalities at existing turbines.
