Providing standby generators for the power required for analogue TV transmitters wasn't viable - the only exception was Bilsdale where two diversely routed mains feeders were not available so a gas turbine generator was provided.
I think the generators referred to in Robert's post are at the studio end, presumably the pylon fault took out much of Glasgow's power too?
Interesting point Steve. Had always thought Divis had a back-up generator. However, it would explain why the Inside Ulster report claimed three quarters of NI's screens went blank. Presumably no RBS from Divis as a result? And lack of generator at Divis would also explain the remarks by the announcer in that 1998 incident about being "off air for a while" as a result of an outage at the TX site.
For the 1995 incident, we do know that the north west of NI was receiving BBC One Scotland and BBC Two Scotland - and a pretty decent signal too. So, presumably Limavady was in RBS mode (and its relays). One can only assume Brougher Mountain switched to RBS and took BBC Scotland too.
Saw a comment by Nathan Dane somewhere that Limavady was confirmed in RBS mode during the 1998 outage.
