What sci fi movie (could have been a "TV" movie) was set in a cavern & dealt with electricity generation?

The struggle in the movie was "cowboy inventor dude" vs "evil corporation". Protagonist is a Robert Redford like dude maybe?.?

It might have had something to do with the sonic properties of the cavern harmonics?.?

I believe there might have been some large "Tesla coil" style lightning special effects during the destruction of the invention (but I could be conflating different movies together.)

Maybe in the 80's?.? (or late 70's / early 90's)?

Thanks! 😃

    Not the power generation segment of Forbidden Planet?

    @Lexible thanks for your suggestion, I checked it out; but it wasn't that old (or that movie.) Sep 9, 2019 at 0:22
