Cost structure of a wind farm

Today’s blog is all about building a wind farm. The chart above shows the breakdown of the EPC cost of a wind farm. While the EPC doesnt make up the entire cost of a wind farm, it makes up the vasy majority of costs. You can see that most of the cost is in the actual generator and the electrical equipment (i.e. lines to connect each generator and the connection to the transmission network).

The most important thing to remember about renewable projects is that the fuel (in this case, wind) is free. Once they are built, you have a zero cost fuel resource to draw upon. This provides distinct advantages over thermal plant that rely upon oil, gas or coal where prices can vary depending upon demand and supply.
