The uniformity of color of the buildings, blue sky with aurora, lack of visible utilities, tells me it's seriously photoshopped, wherever it is
Very few places in Alaska have piped gas, even fewer have buried power - especially on a spit like that
It's also very difficult to actually capture the aurora with ambient light shown in the photo
Looks like elements of SE Alaska, but not very authentic, it's been worked over a lot
Can't say I've ever seen buildings on piers on the shoreline without an actual harbor and docks for canneries or other fish processing facilities to unload fish from tenders
