According to the Blackout Tracker UK Annual Report 2014 from power management company Eaton.
In 2014, there were 537 reported power outages, up from 505 in 2013, 246 in 2012 and 241 in 2011. Outages lasted an average of 67 minutes each and collectively affected 1,059,472 people.
The most common causes were faulty equipment and human error, but animals knocking over electricity power lines, vehicle accidents, weather, theft and vandalism were also factors.
The report highlights emerging threats to the electricity supply, such as growing use of drones, and the UK’s precarious electricity generating capacity caused by the closure of ageing power stations and growing demand for power.
Ofgem, the UK’s energy regulator, has estimated that in the winter of 2015-16 capacity margin could fall as low as 2%. Steve Spicer of Eaton says the Blackout Tracker is a wake-up call for businesses that are ever more reliant on the Internet and IT network infrastructures.
He said: “I hope that this information will act as an incentive for organisations to take preventive measures and ensure they have a reliable power infrastructure solution that can protect against costly and potentially devastating power failures. It is only by doing so that business continuity can be maintained and any disruption minimised.”
