Transmission tariff regulation: CERC expands forensic review of POWERGRID filings
The latest transmission tariff regulation proceedings before CERC indicate a much deeper scrutiny framework emerging for POWERGRID’s interstate transmission assets and tariff recovery claims. Multiple petitions filed on 21 May 2026 sought detailed technical and financial clarifications across Northern, Eastern, Western and North-Eastern Region systems.
One of the strongest signals inside this transmission tariff regulation cycle is the Commission’s heightened focus on additional capital expenditure validation. POWERGRID was directed to furnish equipment-wise ACE break-ups, de-capitalisation schedules, liability-flow statements and linked tariff computation sheets across several transmission projects.
The transmission tariff regulation process also demonstrates increasing attention toward project-cost deviations and capitalisation methodology. POWERGRID Ramgarh Transmission Limited was asked to justify variations between FR-apportioned cost and estimated completion cost for spare ICT assets.
Another major feature of this transmission tariff regulation environment is the expansion of tariff oversight into communication and network-management systems supporting interstate transmission system operations.
