Full wind coverage (4468 wind turbines). At 100% wind efficiency such a farm would yield 1.34 GW.


I, of course, only use polar caps of this BP. Paste this in sandbox (use the tool to fast build) and copy pole segments (as big as you like) to your own blueprints.

Edit: Added BABs to the blueprint to make it self-building:  you must have enough windmills and babs in inventory, otherwise you need to fly over the missing parts with enough in your inventory later. You can remove the 168 BABs later, but after the initial usage, they only use 10 MW in total when idle.
