Hey, i'm on Win10 and have the same loading error.
10.354 Error ModManager.cpp:1560: Fehler beim Laden der Mod „Factorio_Power_RE“: Factorio_Power_RE/data.lua:38: module technology.big-poles not found; no such file Factorio_Power_RE/technology/big-poles.lua no such file Factorio_Power_RE/technology/big-poles.lua no such file core/lualib/technology/big-poles.lua
stack traceback:

Edit:
After Reading your case-sensitive part, i tried to rename the "missing" big-poles.lua and it works now.
Just as mentioned, unzip and rename the file from big-Poles.lua to big-poles.lua and zip it back - works fine (at least in my case).
