National Grid Fending Off 'Huge Amounts' of Cyber Security Threats

tional Grid Plc is fending off “huge amounts” of cyber-security threats, though only a handful have penetrated the company’s computer systems, Chief Executive Officer Steve Holliday said. The U.K. electricity-grid operator — which also owns and operates power and gas networks in New York, Massachusetts and Rhode Island — has identified some attacks from the Middle East and “a lot from China,” Holliday said in an interview at a Bloomberg New Energy Finance conference in London.
