Yup, my home state of Idaho also has a shockingly green energy portfolio. All of the PNW is like that because it's on a shared grid that has been primarily powered by hydro for as long as I've been alive.
And still, we've seen a massive amount of green energy installed here. Both windmills and solar farms.
Yup, Idaho's on that list as well.
But when you look at a grid map you pretty quickly understand why that's the case.

Right now, about 6% of my power comes from natural gas. That's the only fossil fuel power I'm currently using. Everything else is solar/hydro/wind. Not sure why nuclear isn't listed, I thought we had an active plant here. But you get the picture.
For my grid, new solar or wind is simply not needed so why would we be anywhere near the top of installation? Batteries is what we actually need.
There is a point where it's a bad idea to install more renewables.
Idaho Power’s local generation is quite clean. But…during the summer in Idaho, almost a third of energy comes from Wyoming and Utah where coal is still a substantial part of generation.
For what it's worth Oregon and Washington are pretty much at the bottom of new renewable installs: https://www.propublica.org/article/oregon-washington-green-e...
