This seems a bit of a stretch. This power station hasn't been active in close to 50 years and there is no obvious free source as to the location or route of the tunnel. For all we know it has since caved in.
But I guess you can do "rough tracing" and leave it to local editors to sort out later eh ¯\_(ツ)_/¯
