INTRODUCTION

Electricity was generated for the first time in Aizawl in December 1962 using

a 75 kW DG set. The State’s generation capacity was 145 kW prior to the formation

of Union Territory in 1972.Power & Electricity Department became a full-fledged

Department in 1983 headed by a Chief Engineer and subsequently in 2008,the post

of Engineer-in-Chief was created to head the Department.

The Department is now functioning as an integrated utility unit for generation,

transmission and distribution of power within the state of Mizoram. The Department

is also responsible for maintenance of power distribution network to cater quality

power supply to its consumers. The administrative head of the Department is the

Secretary(Power) to the Govt. of Mizoram whereas the Engineer-in-Chief is the

head of the Department in running its affairs. The Engineer-in Chief is assisted by

Chief Engineer(RE) and Chief Engineer(Civil) in his office, 2(two) field Chief

Engineers supported by 19(nineteen) Superintending Engineers in 9(nine) working

Circles, 21(twenty one) Executive Engineers and 52 (fifty-two) Sub-Divisional

Officers and associated staff working round the clock to ensure 24x7 power supply

to the 259961 consumers.

The Department also has given priority for generation of power from the

State’s available huge potential and shifted the headquarters of the Executive Engineer,

Serlui’B’Project Division and its associated Sub-Divisions to Ngopa and renamed

as the Executive Engineer, Hydel Division and 2(two) Sub-Divisions execute

construction of Kawlbem Small Hydro Project(2x2 MW).

The State’s requirement of power is 201MW (as per 18th Electric Power

Survey) whereas the allocated share is 152.89 MW against a Peak demand of 110MW.

This is excluding State owned Hydel Stations (29.35MW) and Tuirial HEP (60MW)

which was not reflected in e-Book 2019-20.

The State is dependent on the outside sources for its energy requirement and

mainly through Central Sector Generating Stations (CSGS) from North Eastern

Power Corporation Limited (NEEPCO), National Hydroelectric Power Corporation

Limited (NHPC), National Thermal Power Corporation Limited (NTPC), ONGC


3

Tripura Power Company Limited (ONGC) and a combined project from Baramura

IV&V (Tripura, Manipur & Mizoram). The daily drawal power requirement of 24

hrs in 15 minutes block based on actual demand of State is sent daily by State Load

Dispatch Centre (SLDC), Mizoram to North Eastern Regional Load Dispatch Centre

(NERLDC), Shillong.

The Department looks after the following assets as on 31st March, 2020 and

are listed below:-

1. Hydel Generating Stations(SHP) - 11 Nos. (29.35 MW)

2. 132 kV lines - 760.30 Km

3. 66 kV lines - 111.42 Km

4. 33 kV lines - 1483.42Km

6. LT lines - 3319.07 Km

7. 11kV ABC - 12.61 Km

8. LT ABC Lines - 127.97 Km

9. 132 kV Grid Sub-Station - 11 Nos. (283 MVA)

10. 33 kV Grid Sub-Station - 62 Nos. (270 MVA)

11. Distribution Transformers - 2701 Nos. (315.35 MVA)

12. Buildings

a) Office Buildings - 37 Nos

b) Residential Buildings - 417 Nos
