Historically, the Indian Power Grid was divided into five regional grids: Northern, Eastern, Western, Southern, and North-Eastern. In 2013, these were all synchronized to operate as a single national grid at a common frequency of 50 Hz.

fsysтАЛ=50┬аHz тАФ The nominal operating frequency of the synchronous Indian national grid.
The synchronization of the five regional grids into a single 'One Nation, One Grid' infrastructure allows for the efficient transfer of electricity between power-surplus and power-deficit regions. This interconnection enhances grid stability, reduces the reserve margin requirement, and ensures optimal utilization of power generation assets across the country.
The 5 regional grids are: Northern (NR), Western (WR), Eastern (ER), Southern (SR), and North-Eastern (NER).
Synchronization of the final SR grid with the rest of the nation occurred on December 31, 2013.
The Central Electricity Authority (CEA) and POSOCO (now Grid-India) manage the national power load dispatch centers.
The system is governed by the Electricity Act, 2003, promoting a unified national grid.
Improved frequency control and system stability.
Higher reliability due to inter-regional power transfer capability.
Optimal use of diverse energy resources (Hydro, Thermal, Renewable).
Increased risk of cascading grid failures if protections are not perfectly coordinated.
Requires complex wide-area monitoring and control systems.
National Power Transmission Planning.
Inter-state power trading via the Power Exchange.
While India acts as a single synchronous grid, these '5 regions' remain the standard administrative and operational nomenclature for regional load dispatch centers (RLDC).
The options provided reflect the classification based on the historical and administrative regional structure still used for planning.
D is correct тАФ India consists of 5 regional grids (Northern, Western, Eastern, Southern, and North-Eastern) that are now synchronously connected to form a single national grid.
Always remember that while India operates as a single synchronous interconnection, regional administrative boundaries (the original 5) are still used for regional power scheduling and energy accounting.
