Wind Project Calculator

Windustry Wind Project Calculator

The Windustry Wind Project Calculator was designed by Alice Orrell, Alice Orrell Consulting, and Windustry for the Community Wind Toolbox.

The Wind Project Calculator was developed to assist in performing cash flow modeling for community wind projects. You will need to enter specific information about the type of turbine you are considering, the estimated annual average wind speed, information about electricity use and electric rates, and information about financing and income taxes. The program will estimate the cash flows for investing in a wind turbine and the rate of return on the cash investments.

Use this calculator in conjunction with software from the Idaho National Laboratory. The software from Idaho National Laboratory is designed to combine validated wind resource data with wind turbine power curves to calculate average wind speed, estimated annual energy production, and capacity factor. Also included with the software is a program to help you create a wind rose for your site. The software is available at www.inl.gov/wind/software/

Comparing Statewide Economic Impacts of New Generation from Wind, Coal and Natural Gas in Arizona, Colorado and Michigan

This 2006 report from the National Renewable Energy Laboratory assesses the direct economic impacts of constructing new electricity from wind, coal and natural gas in three different states. Initial results showed that new electricity generation from wind could be more economically effective than adding new electricity generation from gas or coal power and that new wind electricity generation keeps more dollars local.

A Comparative Analysis of Community Wind Power Development Options in Oregon

A Comparative Analysis of Business Structures Suitable for Farmer-Owned Wind Power Projects in the United States (November 2004) was prepared for the Wind & Hydropower Technologies Program, U.S. Department of Energy, by Mark Bolinger and Ryan Wise.

For years, farmers in the United States have looked with envy on their European counterparts' ability to profitably farm the wind through ownership of distributed, utility-scale wind projects. Only within the past few years, however, has farmer- or community-owned wind power development become a reality in the United States. The primary hurdle to this type of development in the United States has been devising and implementing suitable business and legal structures that enable such projects to take advantage of tax-based federal incentives for wind power. This article discusses the limitations of such incentives in supporting farmer- or community-owned wind projects, describes four ownership structures that potentially overcome such limitations, and finally conducts comparative financial analysis on those four structures, using as an example a hypothetical 1.5 MW farmer-owned project located in the state of Oregon.

Small Packages, Big Benefits: Economic Advantages of Local Wind Projects

This report by Teresa Welsh of The Iowa Policy Project was published April 2005. This report highlights three analyses that compare the economic development benefits of small-scale, locally owned generation to other larger capacity ownership structures and discusses the barriers and changes necessary to aid the development of small scale, locally owned wind generation, specifically in Iowa.
