Major power failure would leave gas & electricity companies in jeopardy
Most gas and electricity companies rely on commercial mobile phone networks that would stop working in the event of a major power failure. Public mobile networks have limited battery back-up which, once exhausted, would leave engineers working to restore vital utilities unable to communicate.
The situation is not a result of mismanagement on the part of either energy companies or mobile phone network operators, but exposes the need for a high-level overview of interdependencies in the UK utility sector.
