Cumbria Meshcore repeater/node resilience in total power outage

Just wondering in the case of a total power outage, this winter in Cumbria, how many of our core Meshcore nodes/repeaters would get knocked out by having no mains supply over several hours or days?

There are some nodes which handle a huge amount of Mesh traffic for example gb-ev-rpt which I think is solar powered so wouldn’t be affected, but can anyone advise which main nodes would be adversely affected?

Quite a few power cuts this morning during the storm, cables damaged/downed seems to be the main reason Fault list
