Difficult to be sure exactly what type of 'utilities' are involved here, so in the absence of more information, 'services' is often a pretty good catch-all term.
Specifically, it may be referring to services like water, gas, etc. which may or may not actually include the electricity supplies.
Then again, it could be referring only to electrical supplies! In some contexts, writers have been know to use 'utilités' to refer to 'auxiliary' power circuits, like domestic plugs and sockets, as distinct from the 'sepcial' dedicated supplies used for the computer equipment. So if you know for sure this is only referring to this type of electrical supplies, then I would be inclined to use 'utilities' or 'utility power' (circuits, supplies, etc.)

It seems that they are on the one hand concerned about security (access control, video surveillance, etc.) — as is rather reassuringly normal for a food handling plant!
And then on the other, issues affecting overall safety, such as fire-break walls; it's not quite so easy to see where doubling up on services fits into that, which seems like it might be more of a BCP issue — but maybe there is also a safety aspect, inasmuch as you wouldn't want your fire-alarm not to sound because the pwoer wasn't getting to it, for example!

Redundant is a pretty standard engineering term for systems of any kind duplicated for fail-safe or backed-up operation.
Possibility of interference by the other more general meaning of surplus to requirements, but in context the specific meaning is clear enough IMO.
