North India’s Grid Safety Nets Still Missing: Defences Remain on Paper
Despite repeated warnings, North India’s grid safety systems remain largely theoretical. As the region enters another demanding winter, key defences like islanding schemes, automatic load shedding, and generator testing have seen little real-world progress — only more meeting minutes and procedural updates.
Islanding Schemes: Still Designs, Not Defences
Multiple islanding schemes — Agra, Lucknow–Unchahar, Jodhpur–Barmer–Rajwest, RSD, and Rajpura — have been in design for years. But the latest 236th and 237th OCC meetings of the Northern Regional Power Committee (NRPC) show that none have reached commissioning.
Punjab was again told to re-submit vetted designs, Himachal Pradesh is only now finalising vendor bids, and most projects remain “under process.” In short: there is still no island-ready infrastructure in North India.
Automatic Under-Frequency Load Shedding (AUFLS): Allocations Done, Action Missing
The AUFLS mechanism — meant to automatically shed load during frequency dips — has allocations finalised, but on-ground feeder mapping and implementation are missing. Without this system in place, the grid would rely on random tripping instead of structured protection in the event of a sharp frequency drop — precisely what AUFLS was meant to avoid.
Periodic Testing: A Rule Without Compliance
As per IEGC 2023 (Clause 40), all generating units, FACTS devices, and HVDC links must undergo testing every five years. Yet, the OCC records show compliance only from a handful of entities — Powergrid, NHPC, SJVN, THDC, JSW Hydro, NLC, Rosa, and LPGCL. Most others haven’t even submitted testing schedules.
These aren’t mere bureaucratic formalities — the tests validate the grid’s simulation models, the backbone of operational planning and stability. The Bigger Picture: Safety Nets Still on Paper
Across multiple OCC meetings, the pattern repeats:
No operational islanding systems
No fully implemented AUFLS layer
No region-wide generator testing compliance
India’s northern grid is one of the most complex — balancing renewable variability, winter peaks, industrial baseloads, and corridor constraints. Yet the defences that matter most exist only in documents, not in the live grid.
