But despite the generally negative tone of the article, it’s actually a useful one, because it brings out in the open a key bit of information: wind power actually brings electricity prices down!

windmills (…) operators in Europe may have become their own worst enemy, reducing the total price paid for electricity in Germany, Europe’s biggest power market, by as much as 5 billion euros some years

The wind-energy boom in Europe and parts of Texas has begun to reduce bills for consumers.

Spanish power prices fell an annual 26 percent in the first quarter because of the surge in supplies from wind and hydroelectric production

This tidbit of information, which will hopefully begin to contradict the usual lies about the need for hefty subsidies for the wind sector, has been publicised by EWEA, the European Wind Energy Association in a report on the merit order effect (PDF). This is the name for what happens when you inject a lot of capital-intensive, low-marginal-cost supply into a marginalist price-setting market mechanism with low short term demand elasticity – or, in simpler words: when you have more wind, there is less need to pay to burn more gas to provide the requisite additional power at a given moment.

I’ve long argued that this was one of the strongest arguments for wind (see my article on The cost of wind, the price of wind, the value of wind from last year), and I’ve pushed the EWEA people to use it more – so this study (which I was not involved in) is most welcome.
