A cyber attack took place on the automatic meter reading system (AMR) of Haryana power utilities in Panchkula and encrypted the data base, an official said here today.
However, there was no loss of the billing data as a backup was already available with the Uttar Haryana Bijli Vitran Nigam (UHBVN), the official said, adding that the billing of consumers was also not affected.
"There is no business loss and there is continuity in the business," he said.
The cyber attack took place on March 21 on the AMR through which the billing of about 4000 Industrial consumers is being done, he said.
The system is installed, operated and managed by Tata Consultancy Services Ltd. (TCS) since 2011.
