Transmission deviation charges India surge due to delayed GNA recognition
Transmission deviation charges India during early 2026 expose a critical flaw in deviation accounting under the GNA regime. March RTDA data and WRPC settlement records show that approved access revisions were not reflected in billing systems for months, despite being operationally effective.
Generators received revised GNA instructions from NLDC in October 2025. Dispatch followed those directions to maintain regional frequency. Yet settlement software continued to calculate limits on legacy access values. As a result, scheduled injections were misclassified, and Transmission deviation charges India accumulated continuously across December, January, and February.
This created a closed negative loop. Each settlement period reinforced the previous deviation position, regardless of physical compliance. For merchant industrial plants, the mismatch had immediate cash-flow consequences. Power was supplied, penalties were levied, and revenues were eroded before any corrective revision could be processed.
The magnitude is visible in RTDA annexures, where deviation volumes were priced at Rs 408 per MWh under temporary access logic. Such rates are punitive when applied to tens of thousands of units. Once settled, the charges could not be commercially recovered.EnergylineIndia.com documents how Transmission deviation charges India are shaped by administrative timing, not just grid behaviour. The case highlights weaknesses in power deviation settlement design and flags the need for real-time integration within General Network Access India to prevent systemic financial leakage, Transmission Charges, GNA Framework, Deviation Settlement, Power Finance.
