Who coordinates for trans-national exchange of power?

Question

Examoogle · Accepted Answer

NLDC

Explanation: The National Load Despatch Centre (NLDC) is the apex body responsible for the optimum scheduling and dispatch of electricity on an all-India basis. It acts as the nodal agency for coordinating trans-national power exchanges, including inter-country interconnections with neighbors like Nepal, Bhutan, and Bangladesh.

Working Principle: NLDC functions under the Power System Operation Corporation (POSOCO/GRID-INDIA) and oversees the regional load despatch centres (RLDCs). It manages the grid security, real-time grid monitoring, and the commercial coordination of cross-border power flows by interfacing with the transmission licensees and regulatory authorities of respective countries.

Key Formulas: $P_{trans} = \frac{V_1 V_2}{X} \sin(\delta)$ — Represents the real power flow across international interconnections based on voltage magnitude and phase angle difference.

Key Points: NLDC is established under the Electricity Act, 2003.; It maintains the All-India Synchronous Grid stability.; Coordinates cross-border power flow with the Ministry of External Affairs and Ministry of Power.; It serves as the central nodal agency for inter-regional scheduling.

Advantages: Optimized resource utilization across borders.; Enhanced regional energy security and grid reliability.

Disadvantages: Complex regulatory coordination between nations.; Increased risk of grid disturbances spreading across national boundaries.

Applications: Exporting surplus hydro power from Bhutan to India.; Coordinated power balancing between India and Nepal/Bangladesh.

Additional Info: Option B (ERLDC), C (NERLDC), and D (NRLDC) are Regional Load Despatch Centres (RLDCs) that handle regional power flow and scheduling within India but do not coordinate the national-level trans-national agreements independently of NLDC.

Answer: A is correct — NLDC is the central nodal agency responsible for the coordination of trans-national power exchanges.

Exam Tip: Always remember that while RLDCs handle regional grids, the NLDC acts as the unified 'brain' for national and international grid integration and policy enforcement.
