Hi Thomas

Your thread has been read lots of times but without reply so I will try to get the ball moving.

So, the first question that I think you need to consider is WHY you are tasked with doing this?

Is it about ticking a box for a potential Tier 1 Contractor or are you doing this for good reason - and if the latter, what types of work do you want to cover and WHY?

You have already set out some of the reasons why PTWs can be overkill and counterproductive!

As example if someone was sending me into a live substation I would expect this to be under very strict controla and probably a PTW would be a sensible component of those. However, since I do not have appropriate qualifications and experience, it's more likely that the simple precaution is to tell me NOT to enter the substation end of. Do the people who work day after day in HV envirionments need PTWs? Probably usually NOT as they work to established protocols that include for lots of precautions and are all subject to stringent training etc AND of course close supervision for those learning their trade.
