More on energy and technology. I love this stuff.
Iowa to harness wind at compressed air power plant: "A group of Iowa municipal electric and gas utilities plans to build a $200 million generating station based on a technology called compressed air energy storage, or CAES, near Fort Dodge, Iowa, .. starting work on the plant site is the second half of 2004 with completion in 2006. The Iowa Stored Energy Plant would store compressed air in an underground aquifer to be released and blended with natural gas to fire combustion turbines to make electricity for transmission over the state's power grid. Compressed air would replace about two-thirds of the gas normally burned in a turbine. Backers said the stored energy could generate up to 200 megawatts of electricity, or power for about 200,000 homes.
Energy from a new 100 megawatt wind power farm would be tapped to run compressor motors to force air into the aquifer at a pressure of 500 pounds per square inch. Wind turbines also could generate electricity for direct transmission over the grid, with 1 megawatt powering about 300 homes." The benefit is generating and selling power when it's needed most and brings the best price. "There is only one other compressed air energy storage plant in operation in the United States, the Alabama Electric Cooperative Inc.'s 12-year-old McIntosh power station in McIntosh, Alabama."
