BBC Research & Consulting's 2005 report for the National Wind Coordinating Committee that studies 9 wind plant sitings in an effort to identify circumstances that distinguish welcomed projects from projects that were not accepted by communities.

Editor's Note: The authors’ conclusion regarding ‘effective capacity’, i.e. the measure of a generator’s contribution to system reliability that is tied to meeting peak loads, is that it “is difficult to generalize, as it is a highly site-specific quantity determined by the correlation between wind resource and load” and that ‘values range from 26 % to 0% of rated capacity.” This conclusion is based, in part, on a 2003 study by the California Energy Commission that estimated that three wind farm aggregates- Altamont, San Gorgonio and Tehachpi, which collectively represent 75% of California’s deployed wind capacity- had relative capacity credits of 26.0%, 23.9% and 22.0% respectively. It is noteworthy that during California’s Summer ’06 energy crunch, as has been widely publicized in the press, wind power produced at 254.6 MW (10.2% of wind’s rated capacity of 2,500MW) at the time of peak demand (on July 24th) and over the preceding seven days (July 17-23) produced at 89.4 to 113.0 MW, averaging only 99.1 MW at the time of peak demand or just 4% of rated capacity.

Sen. Lamar Alexander (R-TN) -- I am here today to introduce - along with the senior senator from Virginia, Senator John Warner - the Environmentally Responsible Wind Power Act of 2005.

This page [author's website] is dedicated to economic information that applies to wind-power projects anywhere in the United States and specifically applies to the Highland New Wind Development project proposed for the northwestern corner of Highland County, VA. Let me say right up front that I am not an economist or tax accountant. I will try to compile factual information on the economics of wind power along with the opinions of recognized experts in this field.
Editor's Note: This provides a good overview of the production tax credit, capacity factor, renewable portfolio standards, renewable energy certificates. and accelerated depreciation. Readers are encouraged to visit the author's site via the link below for the most current version, e.g. the author is planning to update the production tax credit information to the current prevailing rate of 1.9 cents per kWh.

To maximize the advantages that the production tax credit offers, however, requires a closer look at how wind power facilities are financed. Unlike most power projects which are financed based on their revenues from power sales, financing for wind power projects depends heavily on the production tax credits.

If you really want to cut energy consumption, reduce pollution, improve public health and protect our environment, it’s time to contact your elected officials, educate them about the lessons of Denmark, Germany and elsewhere, and tell them you want tougher energy efficiency measures instead of wind power plants.
Otherwise, in the next few years, you’ll be looking at wind turbines in some of your favorite places, with the knowledge that they’re doing little more than funneling your tax dollars to a few lucky corporations and landowners, and away from better solutions.

Large wind turbines require a large amount of energy to operate. Other electricity plants generally use their own electricity, and the difference between the amount they generate and the amount delivered to the grid is readily determined. Wind plants, however, use electricity from the grid, which does not appear to be accounted for in their output figures.

...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.

A necessary step in any attempt to understand the outlook for US energy supply and demand
