ERCOT aka Texas isn't showing up. It says something like "data not available at this time". Does anyone know if data has ever been available from ERCOT? I know that there have been a very large number of wind turbines added to the Texas grid over the last few years, including some near my home town, which I didn't really expect, as that is central Texas and not west Texas where the big farms are. Edit: I will say, at the other end of my home county there is a coal plant.
