Moving wind power not cheap
Utilities spending millions to build transmission lines.

Utilities spending millions to build transmission lines.

The wind is free, but the cost of harnessing its power doesn't come cheaply. Each wind turbine can cost more than $1 million.

Transporting the power from western Oklahoma to the population centers is even more expensive. Texas, for example, is investing almost $5 billion to create its own transmission system.

In the first phase of its transmission line project, OG&E will spend $211 million to build a 345,000 volt line between Oklahoma City and Woodward. It will eventually connect to a 765,000 volt line that will be built by AEP-PSO and OG&E between Woodward and Guymon in the Panhandle.

AEP-PSO is already under contract to purchase about 393 megawatts of wind energy, and is evaluating proposals to purchase another 200 megawatts, which would expand its wind portfolio to about 12 percent of its electricity capacity, said Howard "Bud" Ground, manager of state governmental and environmental affairs for AEP-PSO.

To meet demand, he said AEP-PSO is shopping for another 450-600 megawatts of power and will ask the Legislature to consider incentives that could pave the way for nuclear power plants in Oklahoma.

At 5 p.m. on Tuesday, AEP-PSO set an unofficial peak record at 4,216 megawatts, passing the old record set Aug. 13, 2007, by 41 megawatts, Ground said.

"Wind is not going to solve all the generation problems," Ground said. Because it isn't, utilities have been reluctant to rely too heavily on wind because it can't compete with natural gas or coal as being a reliable source of power.

However, wind speculators are spending more than ever to sign leases to allow them to construct wind towers across northwestern Oklahoma, primarily north of Interstate 40 and west of Interstate 35.

"If you get a turbine on your farm, it will bring the average of $5,000 to $8,000 a year, and the price is going up," Greene said. "It used to be one developer might be knocking on the door. Now it's several developers, and a farmer can replace $10 in hay with a $5,000 turbine."

Wind turbine facts

About two wind turbines can fit on one acre of land.
At maximum speed of 20 revolutions per minute, the tips of blades are moving at 180 mph.
A 1-megawatt turbine can power 300 Oklahoma homes.

The average wind turbine:

Total weight: 187,000 pounds

Tower height: 260 feet

Base diameter: 14 feet

Length of blades: 121 feet

	Report Comment Legal Citizen, (8/12/2008 12:50:03 PM) Tony: "I would go much further and put a small wind turbine on every sign pole, light pole, traffic signal etc." LOL! Oh, wait... were you serious?
	Report Comment Hijinx, (8/11/2008 10:05:32 AM) Nuclear, is very expensive to build and operate. You think this wind deal is costly, just wait till you get the bill for a new “Black Fox”. Not to mention what to do with waste that has a 10,000 year half life. Burying it is the equivalent of burying your head in the sand. Until that problem is solved I cant support nukes.
	Report Comment BobInTulsa, (8/11/2008 10:04:24 AM) If the house is on a large lot, an acre or so, a residential wind turbine might make sense. The tower needs to be 80 to 120 feet tall. Personal wind turbines won't work for everyone. Going solar will be more practical for many. A wind turbine on every street lamp would not work. A Google of "wind turbine residential" will locate an article, "What do I need to know...." that has more information on the subject.
	Report Comment Graychin, Eucha (8/11/2008 9:22:30 AM) Some up-front investment, then zero fuel cost. There's no such thing as a free lunch, but this comes very close.
	Report Comment Tony G, (8/11/2008 6:58:14 AM) Why so big? I think we would do better to downsize these monsters and add one to every home in Oklahoma. I would go much further and put a small wind turbine on every sign pole, light pole, traffic signal etc.
