Navigating PM KUSUM Component C: Feeder-Level Solarization and DISCOM Execution Guidelines

The Evolution of Agricultural Solarization

Under Component C of the national PM KUSUM scheme, the focus shifts to feeder-level solarization of agricultural electricity loads. Instead of solarizing individual solar pumps on separate farms, state utilities solarize the entire agricultural feeder at the local 33/11kV substation. This centralized approach dramatically improves grid stability and reduces distribution losses.

For developers, executing feeder-level solarization tenders requires highly coordinated technical engineering and prompt regulatory clearances with local DISCOMs.

Technical Grid Interconnection Standards

Centralized agricultural feeders demand rigorous grid code compliance to prevent voltage fluctuations and ensure high performance. Technical requirements include:

• Precision Power Flow Analysis: Auditing the load profile of the target substation to size the solar array (typically 1.5 times the cumulative capacity of agricultural pumps connected to the feeder).


• Telemetry and SCADA Integration: Substation-level solar plants must integrate real-time RTU (Remote Terminal Unit) data feeds to DISCOM control centers, allowing load dispatchers to monitor active/reactive power runs.


• Net-Metering Coordination: Installing bi-directional tariff-compliant energy meters at the substation bay to measure net export energy and secure monthly PPA payments.
