Avista Utilities currently has 50% of generation from hydro and a small portion from one wind farm. Oh yes, a token quantity of solar panels are available for selected customers who pay a slight premium.
The rest is from a CCGT and the Colstrip MT coal burner which is scheduled to be turned off. So it appears that Avista is going to replace it with these planned wind farms and a substantial dose of so-called energy efficiency.
I suppose that is about the same as what other utilities in the USA are doing. I just included here because Avista Utilities is my electricity provider and so I know a little about their performance .
