Six wind tower sections left DMI Industries, located at the Tulsa Port of Catoosa, on Tuesday en route to a wind farm site in northern Texas. ...Less than a year ago, DMI Industries, an Otter Tail company, bought a plant built for Griffin Wheel -- a railcar manufacturer that never moved in -- to extend its geographic reach and meet the growing demand for wind towers in the southwestern states.

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.

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.

Greenblatt noted that while wind power could produce impressive amounts of peak energy during strong gusts, the biggest problem was wind power’s intermittency. The problem could be addressed by a process called compressed air energy storage, where excess energy could be used to pump compressed air into underground storage facilities that could include abandoned mines. When the wind was not blowing, he said, the compressed air could be tapped and combined with the burning of natural gas to create high-efficiency electrical generators approximating the efficiency levels of coal-fueled power plants.
