High power on a fiber has a problem called "fiber fuse" (https://en.wikipedia.org/wiki/Fiber_fuse https://en.wikipedia.org/wiki/Fiber_fuse). I followed the link on this article to the article on a more recent solar storm (https://en.wikipedia.org/wiki/Solar_storm_of_2012 https://en.wikipedia.org/wiki/Solar_storm_of_2012) where I found a report from Lloyd's which mentions that there are workarounds (like "neutral-current-blocking capacitors"), so it might be possible to make even large power transmission systems resistant against solar storms.
