Truing Up of Transmission Tariff for the previous period (2019-24).

Determination of Transmission Tariff for the upcoming period (2024-29).

Affected Assets: Various high-voltage transmission assets, including substations, line bays, Inter-Connecting Transformers (ICTs), and HVDC stations across Northern, Western, and Southern India.

II. Primary Financial Dispute

The Issue: The central dispute focused on PGCIL’s claim for Additional Capital Expenditure (ACE) in Petition No. 329/TT/2025.

PGCIL’s Claim: PGCIL claimed a projected ACE of ₹169.28 Lakh for FY 2024-25, based on Regulation 25(1)(d) of the 2024 Tariff Regulations.

CSPDCL’s Objection: The respondents (specifically CSPDCL) challenged the claim, arguing it was “premature and unsubstantiated.”

The claim was based on “management estimates” only, with no evidence of actual liabilities or works executed before the July 31, 2024, cut-off date.

They requested the tariff claim be approved only subject to prudence checks to prevent imposing an unsubstantiated financial burden on beneficiaries.

Specific Financial Disclosure (Petition No. 268/TT/2025): PGCIL must submit, on an affidavit, detailed, item-wise financial data comparing the ACE approved in previous orders against the ACE claimed in the instant petition, along with justifications for any variations.

Order Reserved: Subject to the above submissions, the Commission reserved its final orders in all matters.
