Eastern Grid’s Digital Backbone Moves from Blueprint to Action
By EnergyLineIndia.com | Sector: Power & Energy Infrastructure | May 27, 2025
After years of policy groundwork, the Eastern Grid is finally shifting gears — from drafting frameworks to delivering field execution. What was once a maze of guidelines, committees, and feasibility notes is now becoming a functioning digital ecosystem, powered by real-time monitoring, MPLS rollout, and cyber audit compliance.
With UNMS-based availability tracking, monthly outage planning, and cyber-security protocols going live, the Eastern region’s communication backbone — its network of control rooms, substations, and telemetry links — is now the silent engine of India’s next grid revolution.
From Framework to Field
The 17th TeST (Telecommunication and System Telemetry) meeting of the Eastern Regional Power Committee (ERPC), held on 27 May 2025, confirmed what industry watchers have been anticipating: the region has officially moved from policy drafting to execution.
The Unified Network Management System (UNMS) is now live, enabling communication link availability tracking across utilities. Outage planning for telecom systems — long overdue since the 2017 CERC Communication Regulations — is finally being treated with the same rigour as transmission shutdowns.
States have been asked to nominate nodal officers for a new Network Monitoring Team (NMT) to validate link performance and compliance.
Accountability in the Cloud
The Eastern Grid’s digital backbone is now continuously auditable. Every data link failure, fiber cut, or outage leaves a digital trace — making it possible for ERPC and ERLDC to correlate grid reliability with communication uptime.
POWERGRID will label each communication channel with unique alphanumeric codes to identify ownership and accountability. In essence, telecom reliability is now part of grid discipline.
MPLS and the Future Network
The next-generation MPLS-based communication architecture is gaining traction. The Joint Committee report, led by CTU, has been finalized and awaits NPC approval.
A phased rollout plan proposes a dual network — where legacy SDH systems run in parallel with MPLS until complete migration. The first regional workshop on MPLS implementation is planned for SLDCs, ISGS, and IPPs in the Eastern region.
Cyber Security Takes Centre Stage
Cyber security is no longer a discussion point; it’s an implementation track. Under the CEA’s Cyber Security Framework, third-party audits will commence across utilities, followed by the creation of Security Operations Centres (SOCs) at each SLDC.
The focus has shifted from “where to install” to “how to monitor and maintain.” The grid’s digital defences have entered an enforceable compliance phase, where resilience is measurable and monitored.
The Last Mile and the Long View
Challenges remain — Sikkim’s last-mile connectivity, non-reporting PMUs, and SCADA–SEM data mismatches — but the narrative has changed. The conversation is no longer about feasibility; it’s about monitoring, accountability, and uptime.
For a sector once defined by relay rooms and hardwired systems, this represents a quiet revolution — a software-led transformation where data reliability is as vital as physical infrastructure.
