A)
Mizoram State Electricity Regulatory Commission
B)
Mizoram Electricity Regulatory Commission
C)

Electricity Regulatory Commission for Mizoram
Under the Electricity Act, 2003, state governments are required to establish a State Electricity Regulatory Commission (SERC) to regulate the electricity sector. For the state of Mizoram, the statutory body established to perform these functions is the 'Mizoram Electricity Regulatory Commission' (MERC). While it is a 'State' commission by nature, the official nomenclature used in government notifications and official documentation is the Mizoram Electricity Regulatory Commission. Option (a) adds an unnecessary word 'State', and options (c) and (d) are incorrect as Mizoram does not operate under a Joint Commission (which is a shared body between multiple states) nor is the phrasing in (d) the official title.

The level of voltage classified as Extra High Voltage as described by JERC Supply Code Regulation is-
A)
Voltage exceeds 220 kV
B)
Voltage exceeds 66 kV
C)
Voltage exceeds 132kV
D)
Voltage exceeds 33kV
According to the Joint Electricity Regulatory Commission (JERC) Supply Code Regulations (which govern the North Eastern states including Mizoram), voltage levels are categorized to standardize the distribution and transmission of electricity. The classifications are generally as follows:
1. Low Voltage (LV): Voltage up to 1 kV.
2. Medium Voltage (MV): Voltage exceeding 1 kV but up to 33 kV.
3. High Voltage (HV): Voltage exceeding 33 kV but up to 132 kV.
4. Extra High Voltage (EHV): Voltage exceeding 132 kV.
Therefore, any voltage level that exceeds 132 kV is classified as Extra High Voltage (EHV).
- Option (a) is incorrect because 220 kV is a specific EHV level, but the threshold for the classification starts above 132 kV.
- Option (b) is incorrect as 66 kV falls under High Voltage (HV).
- Option (d) is incorrect as 33 kV is the upper limit of Medium Voltage (MV).

Therefore, the Regional Load Despatch Center (RLDC) responsible for the coordination and control of the grid in the North Eastern states, including Mizoram, is the North Eastern Regional Load Despatch Center (NERLDC).
Breakdown of options:
- MSLDC (Mizoram State Load Despatch Center): This is the state-level center, not the Regional center.
- ERLDC (Eastern Regional Load Despatch Center): This controls the Eastern region (e.g., West Bengal, Bihar, Odisha).
- ASLDC (Assam State Load Despatch Center): This is the state-level center for Assam.
- NERLDC (North Eastern Regional Load Despatch Center): The correct regional authority for the North Eastern grid.
