What is a DISCOM?

A DISCOM (Distribution Company) is the last-mile electricity utility in India. It owns and operates the distribution network (11 kV and below), purchases power from generators and traders, and retails it to consumers at SERC-regulated tariffs.

DISCOMs and rooftop solar

For any grid-connected solar installation, the DISCOM:

• Receives and processes the net-metering application
• Inspects and approves the installation before grid connection
• Installs the net/bidirectional meter
• Issues a No-Objection Certificate (NOC) where required
• Settles net-metering credits on monthly bills
