Main function of NLDC is
Prepare Policy of power grid
Prepare Grid code
Supervision over all RLDC
All of above
Supervision over all RLDC
Quick Summary: The National Load Despatch Centre (NLDC) is the apex body mandated under the Electricity Act 2003 to ensure integrated operation of the power system in India. Its primary function is to supervise the Regional Load Despatch Centres (RLDCs) to ensure grid stability and reliability at the national level.

Pflow=XV1V2sin(δ) — Power flow equation monitored by NLDC
NLDC acts as the strategic coordinator between Regional Load Despatch Centres (RLDCs). It manages the national grid by monitoring inter-regional power flows, managing national transmission constraints, and facilitating energy accounting/billing through the POSOCO (now GRID-INDIA) framework. It does not formulate grid codes or power policies directly, which are the domains of the CERC and Ministry of Power, respectively.
NLDC is the apex body for integrated operation of the national power grid.
Functions include scheduling of inter-regional power transfers and monitoring real-time grid parameters.
Operates under the administrative control of GRID-INDIA (formerly POSOCO).
Works in coordination with Regional Load Despatch Centres (RLDCs) and State Load Despatch Centres (SLDCs).
Enhanced national grid security and stability
Optimized inter-regional power transmission
High dependence on communication infrastructure
Complex coordination requirements across diverse states
Real-time grid frequency monitoring
Inter-regional energy scheduling and accounting
NLDC was established under Section 26 of the Electricity Act 2003.
Policy formulation is the responsibility of the Ministry of Power, and Grid Code preparation is governed by CERC regulations.
C is correct — The main statutory function of the NLDC is to exercise supervision and control over all Regional Load Despatch Centres (RLDCs) to ensure the integrated, secure, and efficient operation of the national power system.
Always remember that NLDC 'supervises/coordinates' (operational function) rather than 'legislates/defines' (policy/coding function) to distinguish it from CERC/Ministry roles.
