First Winds Holdings ( WIND) has sold its equity interests in certain projects. This arrangement entitles the investors to most of the cash flow and tax benefits until they achieve their targeted investment returns, which could take 10 years. So new investors will have to wait some time before First Winds gets to keep this cash. Plus, there's no guarantee that the tax benefits will remain in place. Congress must vote to extend them. Competition is heavy in the wind power business and the price for the power is high compared to natural gas. While many investors like the idea of wind power, the bottom line for this company isn't so powerful.
