New Delhi: Union Power Minister RK Singh on Tuesday said that the Mumbai power outage last October was caused by "human error" and there is no evidence to prove that it was triggered due to a cyberattack by China. Speaking to ANI, Mr Singh said, "Two teams investigated the power outage and reported that the outage was caused by human error and not due to cyberattack. One of the teams submitted that cyberattacks did happen but they were not linked to the Mumbai grid failure," "The cyberattacks happened on our northern and southern region load dispatch centres. However, the malware could not reach our operating system. Maharashtra Home Minister has informed that cyberattacks happened on their Supervisory Control And Data Acquisition (SCADA) system in Mumbai," the minister added.
