That's why I was wondering about fttp as typically there isn't much that needs power away from cabs/exchanges. I've been lead to believe that our fttp instead of going to the nearest local exchange is going back to the nearest town exchange, 6 miles by road I didn't know if that meant a slightly different roll out to urban fttp iykwim.
That's standard across the UK, and is where the current FTTC cabinets in your area already run back to.
The OpenReach network is made up parent and child exchanges.
Each parent exchange (also called a Head-End/Handover exchange) has a number of (usually) smaller child exchanges.
All the fibre services (FTTC(VDSL,G.Fast) and FTTP) come from a parent exchange.
If you are on FTTC then your line runs from your home to the cabinet. The copper line continues to your local exchange for voice services. The fibre runs from the cabinet to your Handover exchange.
This means your voice and broadband although on a single phone line, come from 2 separate exchanges.
My local exchange also happens to be the local Handover exchange so all services come from there.
It makes zero difference to your service if your local exchange is a parent or child exchange.
The intention is to close the child exchanges when everyone is on fibre.
As mentioned above by others the only point where power is needed for FTTP is in the parent exchange and your home. It's passive inbetween.
In very rural areas where the parent exchange is too far away for the FTTP signal to travel they can effectively start the FTTP signal from a subtended head-end, but the power for this is shared with an existing FTTC cabinet.
Any local power work is almost certainly unrelated to OpenReach's FTTP rollout.
