This report is sobering reading. "Living without electricity"
https://raeng.org.uk/media/xrrigg0m/raeng-living-without-electricity.pdfOf particular note is that the local radio station, using very dated technology was the main source of information.
Telephone service generally not available.
And that particular incident was in fact a narrow escape ! had the weather been a bit colder, lives could have been lost without heating.
Had the emergency occurred during working hours/school opening hours the impact would have been much greater.
Learning points
Emergency lighting, if it works at all, runs for 3 hours AT THE MOST.
Grid tied wind turbines and CHP plant gives NO protection against power cuts.
Central heating needs electricity.
Most shops will close, and those that remain open will only accept cash.
IMHO▸ , everyone should have the means to heat at least one room to 20 degrees without utility service or re-supply for at least a week.
Bottled water and non perishable food for at least a week.
A battery radio, list of radio frequencies and several spare batteries.
A pocket torch and spare batteries for each person in your household. And a large LED or fluorescent lantern, with batteries for 100 hours operation.
A reserve stock of shirts and underwear in case you can not do any laundry.
