Another Reality Check for Wind Power Investors | Alternative

Another Reality Check for Wind Power Investors | Alternative

The data for wind farm performance is hard to find, but there are people working on it. I wrote about one study two years ago: http://www.altenergystocks.com/archives/2009/04/our_undiversified_wind_portfolio_1.html Part of the problem with BPA is that the location of wind farms is chosen to maximize energy output, not to maximize diversification. This is like putting together a stock portfolio purely on the basis of yield- not a good idea. See the article above. In order to maximize the benefits of geographic diversification, your grid needs to be larger in scale than the weather patterns that drive wind and sun. A look at a national weather map usually shows only around 2-4 different high and low pressure regions in the entire US, so in order to achieve good wind diversification, we'd need a grid that covers at least half the country. The UK is probably not big enough to ...
