Reading the Wind = Using Less Coal
Have you ever been on a sailboat when the wind kicked up and a big gust tossed you into the water? (Not that I have, of course. My friend maintains that he is an “expert captain.”) Or have you experienced the wind dying down and it’s like you’re going nowhere fast? (He’ll deny that one too.) Wind has a similar effect on the power grid – but if you know when the gusts are coming, you can adjust accordingly.
Wind is one of the most difficult weather variables to forecast (as my friend can attest). So many factors affect it – topography, ground cover, temperature inversions – even the number of leaves on nearby trees.
