Just so folk have some context to this the planning application was officially refused on or around 14 March 2024. Section 6 of the Guide to Planning Appeals in Scotland states that the limit for appealing is three months from the date of the decision. Looking at the DPEA website shows a total of six appeals, since the battery form decision, within the Highland Council area. Only three of them are a Planning Permission Appeal (PPA) and they are located in Farr or Drumnadrochit.
So this means that no planning appeal has been submitted for the BESS (yet!) and they have something like 17 days to get one in.
