UK energy industry cyber-attack fears are 'off the scale'

Sector says current threat coming to the fore because of trend towards decentralised power plants

Concern over the threat posed by cyber-attacks on power stations and electricity grids is "off the scale" in the UK energy sector, according to a leading industry figure.

No other country in the world has an energy industry as worried about the risk from cyber threats, such as the WannaCry ransomware attack that recently hit the NHS, the former chief of National Grid told the Guardian.
