Sure. Just use molten salt energy storage, hydroelectric dams or whichever of the dozens of technologies makes most sense where you are.

Combine different kinds of renewables so you get power at night and when the wind isn't blowing. Build more then enough and if you got excess energy, maybe make some hydrogen.

Have your devices and industry 'smart' so it draws less power when there's less supply.

You really don't need to do everything with 'normal' batteries like in a smartphone.

The 'working' thorium reactors are for research. They don't generate energy. At least if we're speaking about generating energy for a whole country. The planned thorium reactors of the next many years also don't generate any significant amount of energy. With that argumentation we also (almost) have nuclear fusion power plants.

A thorium power plant that contributes to the power grid and shows up in the numbers is sci-fi. I mean, it's not impossible. It's just lots of very expensive work left to do.
