I always like researching the power supplies for islands. I spotted this at the far end of Stornoway harbour. You can read about it here. It is on the wonderfully named Battery Point - in the old usage of a gun battery! It seems that the power station is now used as a top up supply in the winter when the demand is higher than can be supplied from the mainland. I'm interested that there are plans for an HVDC cable to connect up the wind turbines to the mainland as well.
