If that is the case, Idaho Power should have specified such possibilities in the contract with the wind power producers.
Maybe it’s not the same in Idaho, but in WA, voters have final say over power contracts and rates. They can’t do anything without voter approval and that is understood, it doesn’t have to be spelled out.
There are no profits in wind energy, outside of government subsidies because the power must used when it is produced, whether it is needed or not and whether there is line capacity at that time or not.
