BP, Dominion laud success of Indiana wind farm venture

BP and Dominion Announce Full Commercial Operation of Largest Wind Farm in Midwest

BP Wind Energy and Dominion have announced full commercial operation of the first phase of the partners’ Fowler Ridge Wind Farm in Benton County, Ind., capable of producing 400 megawatts of electricity in optimum conditions — enough to power about 120,000 homes.

BP and Dominion are currently assessing areas north of Big Stone Gap and Appalachia in Wise County for a potential wind farm project, as well as potential wind farm sites in Tazewell County. Dominion is also the utility building a 585 megawatt coal-fired power plant in St. Paul planned to be operational in 2012. The partners in wind energy projects say they could expand the Indiana facility to 750 megawatts in the future. Construction of the first phase uses 1.65 megawatt turbines with a hub height of 262 feet and a rotor diameter of 269 feet, and 2.5 megawatt turbines with a hub height of about 262 feet and a rotor diameter of 314 feet. A total of 850 workers were employed at the peak of construction of the Indiana project. A full-time staff of 36 is employed to monitor and maintain the first phase of the facility, the companies said.

“The commercial operation of the Fowler Ridge Wind Farm marks an important step for BP in helping Indiana increase its role as a provider of energy to support growing state and national demands. This wind farm will deliver more than 1 billion kilowatt hours of clean, renewable electricity every year and brings new revenue streams to rural communities without impact on traditional farming and grazing practices. The cooperation of the landowners, county officials, contractors and subcontractors has been the key to the success of this project.”

Dominion Chairman Thomas F. Farrell II said such projects represent part of the solution to the nation’s energy-independent future.

“To ensure reliability and price stability, the U.S. will need to utilize diverse fuel sources in the generation of electricity, and these are concrete steps in that direction. Wind is and will continue to be an important part of the mix.”

BP America is the largest producer of oil and gas in the United States and one of the nation’s largest energy investors. For more information, visit the company’s Web sites at http://www.bpalternativenergy.com, http://www.bp.com/us or http://www.dom.com.

Arizona may become a center for solar development

5 solar projects get $4 million in grants

Five new projects granted $4 million in seed money could help make Arizona a center for solar development, backers said Friday. Science Foundation Arizona announced the projects, and the formation of its new Solar Technology Institute, at lunch events in Tucson and Phoenix.

The Tucson event, attended by about 100 industry, government and university officials, was held just outside a 310,000- square-foot solar array that provides power at Global Solar Energy, 8500 S. Rita Road.

"The goal is developing disruptive technology breakthroughs that will bring the cost of solar energy down to the level of fossil fuels. We want to make Arizona a leader in the drive to change to solar."

"Germany, Spain and even New Jersey lead Arizona in the development of solar energy. We've got to change that."

The $4 million will provide startup funding for the projects, Powell said. Half of the funding comes from Science Foundation Arizona and half from the private sector.

The funding is in hand and not affected by state budget cuts for the organization, Powell said.

The projects cover the full solar spectrum, from collecting the sun's energy to distributing electricity to consumers, said Leslie Tolbert, vice president for research, graduate studies and economic development at the University of Arizona.

"The goal here is not just to meet our energy needs but to become a net exporter."

The projects are collaborations that include UA, Arizona State University and a variety of industry partners, she said. Solar panels don't work at night, and energy storage is a challenge that one funded project is addressing, Powell said.

Plans call for generating excess solar power during the day that will be used to compress air that will be stored, he said. When darkness curtails energy production, the stored compressed air can be used to drive turbines to generate electricity, he said.

Another project is using nanotechnology to improve the efficiency of thin-film solar devices while driving the price down, said Ray Kostuk, UA professor of electrical and computer engineering. Ultra-thin coatings will cause sunlight to spend more time exciting the elements in thin-film devices so they produce more electricity, Kostuk said.

Other projects are:

• Concentrator photovoltaics to develop the next generation of low-cost solar reflectors that concentrate the sun's energy on high-efficiency photovoltaic cells.
• Quickly testing and certifying solar products to determine the performance of new and improved technologies.
• An improved system of "smart" electric grid management and command and control software to help select future power generation sites, storage sites and distribution and transmission pathways throughout the state.

Science Foundation Arizona is a nonprofit public-private partnership that invests areas of strategic importance to the state, including renewable energy and biomedicine.
