Submission Statement:

A study from a group of researchers at the Colorado School of Mines looked at powering remote mining sites on earth that aren’t connected to any electric grid.

They found that solar power satellites aren’t yet economical enough to warrant the investment for powering remote mining sites that aren’t connected to any electric grid.

So, the answer to whether a space-based power satellite could power remote mines is “yes,” but there’s not much of a business case for it. There’s still a long way to go before beaming power from space becomes a profitable venture. But, as the authors note at the end of the paper, the whole calculation changes dramatically if some of the parts for the satellite are manufactured in space. So, there is still a point in the future, with a much more fleshed-out space infrastructure, where the price might eventually become competitive.
