The U.S. Department of Energy (DOE) released the 2007 edition of its Annual Report on U.S. Wind Power Installation, Cost, and Performance Trends, which provides an overview of developments in the evolving U.S. wind power market. Notably, the report finds that U.S. wind power capacity increased by 46 percent in 2007, with $9 billion invested in U.S. wind plants in 2007 alone, making the U.S. the fastest-growing wind power market in the world for the third straight year. The report also showed that wind is on a path to becoming a significant contributor to the U.S. power mix—wind projects accounted for 35 percent of all new U.S. electric generating capacity in 2007, and transmission facilities capable of generating a total of over 200 GW of wind power are in the early stages of development throughout the nation.
First issued last year, the report analyzes developments in the wind market, including trends in wind installations, turbine size, turbine prices, installed project costs, project performance, wind power prices, and cost comparisons between wind power and conventional generation. It also describes developer consolidation trends, current ownership and financing structures, and trends among major wind power purchasers.
The second edition improves on last year's inaugural release by adding several new sections that highlight the growing importance of wind power to the nation's power mix and economy. Specifically, this edition tracks significant increases in the contribution of wind power to new capacity additions in the electric sector; the amount of wind power in utility systems; the size of wind projects; and the quantity of wind power capacity in various interconnection queues across the country. It also provides data on the growing number of investments in wind turbine manufacturing capacity in the United States.
Some of the key findings of the report include:
* The U.S. is the fastest-growing wind market worldwide. The U.S. has led the world in new wind capacity for three straight years, and 1.2 percent of the nation's electricity supply could be met with the wind capacity on line at the end of 2007.
* Growth is distributed across much of the U.S. States as diverse as Texas, Colorado, Illinois, and Oregon led the U.S. in annual capacity growth in 2007; nine states had enough wind capacity at the end of 2007 to account for more than three percent of total in-state electricity generation.
* Market growth is spurring manufacturing investments in the U.S. Several major foreign wind turbine manufacturers either opened or announced new U.S. wind turbine manufacturing plants in 2007. New and existing U.S.-based manufacturers also either initiated or scaled-up production. All told, the new turbine and component manufacturing facilities opened or announced in 2007 could create more than 4,700 new jobs in the U.S.
* Wind turbine prices and installed project costs have risen since 2002. Turbine price increases have been driven by weakness in the dollar, higher prices for materials and energy inputs, and shortages in certain turbine components -- factors that are impacting many different types of generating technologies.
* Wind project performance has improved in recent years. This improvement in project performance has been driven in part by enhanced project siting and technological advancements.
* Despite rising project costs, in recent years, wind power has consistently been priced at, or below, the average price of conventional electricity, as reflected in wholesale power prices.
