Can't see an open fault on the PCP suggesting the FTTC cabinet is still up.
The electricity works were emergency repair not planned so certainly something broke.
Either the power failed and they are part way through repair, during other work they've disconnected the feed to the cabinet intentionally or inadvertently, or they've hit D-side copper.
Openreach aren't going to go near it until the power is made safe if it's copper and need to work with the power company if the issue is there.
