Not knowing much about wind power I'd have a guess that they need to measure the wind over each season for multiple years to develop an accurate model to prove its commercially viable. You also have climate patterns like La Nina which impact trade winds but I assume that this would take too long to measure and they would use engineering models to modify their seasonal data.

I think we are still a while away from seeing profits and in turn dividends as the next 5ish years will demand a fair bit of capital (A few batteries and the wind project still need to be financed). Have to be a LT holder on this one.
