The following category of generating units are required to obtain the unique registration number:
  • All the conventional grid connected electricity generating units (whether in Central Sector, State Sector, Private Sector, IPP’s, Joint Venture etc.) in the country whether coal based, gas based, liquid fuel based, Hydro Power based or nuclear, if the capacity of the electricity generating unit is 500 kW (0.5 MW) and above.
  • All the electricity generating units of grid-connected captive power plants, if the capacity of the electricity generating unit is 500 kW (0.5 MW) and above.
  • All the Grid - connected Renewable Energy (RE) generators, if the capacity of RE generating unit is 500 kW (0.5 MW) or above. This also includes grid-connected roof-top solar installations.
  • All the stand alone (off-grid) generating units, if the capacity of generating unit is 500 kW (0.5 MW) or above.
  • All the generating units supplying power to neighbouring countries, irrespective of whether these generating units are connected to the Indian Electricity Grid or not.

In addition, storage device (for example battery storage) of capacity 0.50 MW and above are also required to register. However, Pumped Storage Hydro Generating units would register themselves as a generator.

For existing grid-connected electricity generating units, including grid connected captive and RES generating units, the registration number would be required for injecting power in the grid. For under construction electricity generating units and generating units in conceptualisation stage, which includes grid connected captive and RES generating units, the registration number would be required while applying for grid connectivity. However, if grid connectivity has already been obtained or applied by these generating units, the registration number would still be required for physical injection of power in the grid.

The registration number would be generated online by the generating companies/project developers, after filling in certain details. The Generating Companies would have to register themselves in e-Registration portal of CEA after filling in necessary details viz. name of the generating company, sector etc. in a format designed for the purpose. They can choose any user id and password while registering their generating units. Using the user id and password generated, generating companies can enter the details of their generating units one by one for obtaining the unique Registration Number for each generating unit. The unique registration number shall be a 10-digit numeric identification number in the format XXXXXXXXXX. The first digit will indicate that it is a Generating Company (Generating Company-1). The second digit will indicate the type of generating unit (Hydro-1/Thermal-2/Nuclear-3/RES-4/Storage-5). Digits from 3-10 (8 digits) would be the unique registration number of the generating unit.
