The Central Electricity Authority (CEA) has proposed creating separate tariff categories for rooftop solar net-metering consumers. These include specific fixed charges, variable charges, and differentiated Time-of-Day (ToD) tariffs. This move aims to balance grid requirements and improve cost recovery for DISCOMs as consumer grid-interaction patterns change.

Key Details of the Proposal
Separation of Net-Metering Consumers: -
The CEA suggests isolating net-metering consumers into distinct billing categories. Conventional tariff structures do not adequately capture their unique usage, as these users often import power during non-solar hours and export excess electricity during the day.
Differential ToD Tariffs: -
Time-of-Day pricing will be used to send clear price signals. Because rooftop solar users export energy during the day, these ToD structures are designed to incentivize shifting consumption or storage patterns to align with system requirements. The CEA has noted that ToD differentials may need to increase from 20% to between 30% and 35% of energy charges to retain effective price signals.
Increased Fixed Costs:-
To ensure grid stability, the CEA is recommending a phased increase in fixed-cost recovery. Fixed cost recovery targets for domestic users are slated to progressively increase to 25% by 2030, and up to 50% by 2035.
Under traditional net-metering schemes, DISCOM"s struggles to recover fixed grid and wheeling costs because rooftop solar users heavily rely on the grid as a backup system while reducing their overall purchased energy. These guidelines form part of the broader "Need for a National Framework for Rationalizing Fixed Charges and Tariff Redesign," which pushes for standardized two-part tariffs and uniform billing systems across states.
