MERC declines to revise TPC-D's FY2023-24 interim tariff on remand; MYT tariff (30 Mar 2020) to continue, final FY2024-25 tariff to be decided in Case 237 of 2023
Petition of The Tata Power Company Ltd. (Distribution) for approval of True-up of Aggregate Revenue Requirement (ARR) for FY 2019-20, FY 2021-22 and FY 2021- 22, Provisional Truing-up of ARR for FY 2022-23, and approval of Revised ARR and Tariff for FY 2023-24 and FY 2024-25. Case No. 225 of 2022 (Re-opened in pursuance of Hon’ble APTEL’s Judgement dated 5 January, 2024 in Appeal No. 369 of 2023.)
TPC-D's MTR Order dated 31 Mar 2023 revised tariffs for FY2023-24/24-25 after true-up. TPC-D appealed to APTEL citing excessive hike; APTEL stayed the FY23-24 tariff schedule (13 Jul 2023), restoring MYT (30 Mar 2020) tariff, while true-up stayed in force. On 5 Jan 2024 APTEL set aside the MTR order (except true-up) and remanded, directing MERC to pass a fresh interim/final order urgently considering subsequent events. TPC-D sought an interim tariff adding true-up impact (Rs.0.33/kWh FY23-24, Rs.1.38/kWh FY24-25) to MYT ACoS; AEML-D objected, seeking full fresh adjudication with public hearing, wires/supply segregation, and scrutiny of transmission-constraint claims and TPC-G PPA extension.
- Disposed of the remanded matter in Case No. 225 of 2022.
- Rejected TPC-D's proposed interim tariff hike (Rs.0.33/kWh FY23-24; Rs.1.38/kWh FY24-25) citing time constraints and futility of a fresh public consultation with FY23-24 nearly over.
- Directed TPC-D to continue levying the MYT tariff for FY2023-24 as restored by APTEL's interim order dated 13 July 2023.
- Held that final tariff for FY2024-25 (including provisional true-up of FY23-24) will be decided in Case No. 237 of 2023, factoring in APTEL's observations and subsequent events (e.g., TPC-G PPA extension).
- Allowed AEML-D to raise all its objections (transmission constraints, wires-supply segregation, PPA extension) in Case No. 237 of 2023, already listed for public hearing on 27 Feb 2024.
- Directed TPC-D to forward its Case 237/2023 tariff petition to STU and MSLDC for comments on transmission constraints.
- TPC-D continues to bill FY2023-24 at MYT (30 Mar 2020) tariff—no interim hike for FY23-24.
- Final FY2024-25 tariff (with provisional FY23-24 true-up) to be determined in Case No. 237 of 2023 via full public consultation.
- TPC-D to send copy of Case 237/2023 petition to State Transmission Utility (STU) and MSLDC for comments on transmission constraints.
- AEML-D to file objections/suggestions (wires-supply segregation, transmission constraint issue, PPA extension impact) in Case 237 of 2023; TPC-D to respond.
- MERC to incorporate APTEL's 13 July 2023 observations and all subsequent events while issuing the final order in Case 237 of 2023.
- No further interim tariff order will be issued for FY2023-24; matter treated as closed for that year.
- • C&I consumers on TPC-D's network see no tariff change for FY2023-24 — MYT (2020) rates continue; the true-up hit is deferred entirely to the FY2024-25 tariff order.
- • Open access and change-over consumers should watch Case 237 of 2023 closely, as MERC has flagged that wires vs supply cost segregation is essential before any wheeling/energy charge revision.
- • The confirmed 5-year PPA extension with TPC-G (till 2029) signals continuing transmission constraints in Mumbai — relevant for RE/open-access developers assessing wheeling feasibility and embedded generation dependence.
- • Expect a potentially sharper tariff correction in FY2024-25 once the deferred FY23-24 true-up and provisional FY23-24 gap are both loaded into that year's ARR — C&I buyers should factor this into budgeting and PPA planning.
This is a procedural stop-gap, not tariff relief. MERC essentially punted the true-up recovery to the FY2024-25 order (Case 237/2023) rather than force a rushed public consultation for a near-ending FY23-24. C&I consumers get short-term breathing room but should brace for a larger cumulative tariff correction in FY24-25 once both years' true-up gaps stack up. The wires-supply segregation issue MERC flagged is important for OA/C&I developers — push for clarity in Case 237 submissions to avoid being charged for supply-side gaps you don't consume. Track the 27 Feb 2024 hearing outcome closely.
