NTAMC (National Transmission Asset Management Centre) has been established for centralized remote control and monitoring of POWERGRID substations across India. To ensure reliable operation and system redundancy, NTAMC is supported by Regional Transmission Asset Management Centres (RTAMCs), located across various POWERGRID regions. In addition, Backup NTAMC has been established as disaster recovery Centre for Main NTAMC.
The control centres are equipped with state-of-the-art software applications including some unique features implemented for the first time in power sector to address growing competitiveness of Indian transmission sector. It is one of the ambitious projects undertook by POWERGRID, despite underlying challenges of upgrading the existing old & conventional system in live environment. It also necessitated up skilling staff from traditional substation operations and maintenance to new technology.
As on August ’2026, 296 nos. of EHV Substations of POWERGRID are being controlled & monitored from Control Centres.
