...additional radar studies would be required to see if spring migration patterns are different than those measured in the fall. Typically spring migration is shorter than fall migration with fewer numbers in the shorter period of time. How this will affect the numbers of birds passing through the rotor swept volume is unknown. It is important to determine the seasonal timing, altitude and numbers of migrant birds passing over the proposed project site and the effects of weather upon their passage over a greater part of the whole year. In addition, it is possible to determine some of the bird and bat species passing through the project site by accoustical sensors to determine which species, that make vocal calls, are migrating through the site.
The report notes that U.S. wind power capacity increased by 27 percent in 2006 and that the United States had the fastest-growing wind power capacity in the world in 2005 and 2006. For the second straight year, the United States led the world by installing 2,454 megawatts of wind power capacity in 2006—16 percent of the capacity installed worldwide that year—followed by Germany, India, Spain, and China. Leading the way in annual growth capacity in the United States are Texas, Washington, and California.
--conservation of wildlife in the public trust;
--development of renewable energy that is bird and bat friendly; and
--use of informed decisions based on adequate environmental assessment and sound science.
At the same time, there has been a growing interest in community wind power development. While the notion of community wind varies, these projects are generally smaller scale (less than 20 MW), and are locally initiated and owned. Projects range from single turbines erected by municipal utilities, school districts and tribal reservations to larger multi-turbine installations owned by one or more local investors and landowners. These projects may capture and retain more of the economic benefits locally (both construction-related and ongoing returns) and drive continued reinvestment in the communities. As a result, community wind projects often enjoy more favorable community support than large-scale commercial projects.
There have been numerous publications and conferences on community wind development, but less specific attention on options for project structuring and financing. The goal of this handbook is to identify critical financing issues and present several possible financing models that reflect the differing financial positions and investment goals of various project owners/developers.
The handbook includes six sections:
• Section I describes various models for community wind power ownership.
• Section II examines sources of equity and debt financing and the steps necessary to secure this financing.
• Section III identifies federal grant and loan programs and state incentives for wind power development.
• Section IV reviews the federal tax incentives supporting wind power projects, the impact of these incentives on project economics, and limitations on utilizing these incentives.
• Section V examines power purchase agreements and the value of green tags to community wind power projects.
• The Appendix contains a list of operating community wind projects in the United States and a list of project consultants and financing resources.
