Our Business

Power System Management:

AEGCL manages the State Grid in Real time through State Load Despatch Centre.

Planning & Design of Transmission Network:

Our core business is the transmission of electric power. AEGCL evacuates power from

  • State owned/IPP generating station
  • Powergrid’s interface point along
  • Intrastate import/export point.

To meet the increasing power demand of Assam, AEGCL has been involved in capacity building of its Transmission Network by constructing EHV Sub-stations and Transmission Line as well as augmenting its existing assets.

AEGCL grid can handle upto 1620 MW. Presently, AEGCL operate more than 5761 ckt. kms. network of transmission lines, 5446 MVA transformation capacity and 55 nos EHV Grid Sub-stations.
To improve the voltage profile at 33 KV end, AEGCL added 285 MVA of reactive compensation in its various sub-statons.

At the end of the 12th plan period, total no of substations will be as follows:

  • 400/220/132 KV- 1 No.
  • 220/132/66/33 KV – 2 Nos.
  • 220/132/33 KV – 9 Nos.
  • 220/132 KV – 2 Nos.
  • 220/33 KV – 1 Nos.
  • 132/66/33 KV – 2 Nos.
  • 132/33 KV - 59 Nos.
  • 132/11 KV – 1 Nos.

Operation & Maintenance:
AEGCL takes continuous effort in operation and maintenance of the Transmission Lines and EHV Sub-stations to ensure high availability of the system. Due to the consistent maintenance, system availability is more than 98.5%.

Optical Fiber Network:
At present, AEGCL has 1373 km. of OPGW (optical ground wire) network out of which AEGCL undertook a project for replacing 614 km. of the existing Ground Wire of different transmission lines with OPGW under Assam Power Sector Enhancement Improvement Project (APSEIP). Under Microwave replacement project, 759 km. of Ground wire has been replaced with OPGW .In future AEGCL plans to use the optical fiber network for business venture.
