Electricity network companies face having to further beef up their defences against cyber attacks as the rise of small-scale renewable power generation increases the vulnerability of the grid to attack.
Network owners, which have already increased their cyber-security defences in recent years, have been shaken by the cyber-attack in western Ukraine late last year, which caused blackouts for more than 200,000 customers.
Now, as more households install rooftop solar systems and batteries, the number of connection points to the grid is increasing, potentially opening up more chances for breaches, said Energy Networks Association chief executive John Bradley.
