MERC issues corrigendum correcting oversights in AEML-D's 31 Mar 2023 MTR Order; errors to be adjusted in future true-ups, not current tariff
Corrigendum Order: Case of Adani Electricity Mumbai Limited (Distribution Business) for Approval of Truing-up of FY 2019-20 to FY 2021-22, Provisional Truing-up for FY 2022-23 and Revised Aggregate Revenue Requirement for FY 2023-24 and FY 2024-25
MERC had passed the MTR Order dated 31 March 2023 for AEML-D covering truing-up of FY2019-20 to FY2021-22, provisional truing-up for FY2022-23, and revised ARR for FY2023-24 and FY2024-25. On review, the Commission identified four inadvertent errors/omissions in that Order relating to (i) non-deduction of AEML-G's true-up surplus from AEML-D's Supply ARR/tariff for FY2023-24, (ii) non-inclusion of AEML-D's share of Standby Charges refund from TPC-G, (iii) non-consideration of approved Wheeling Charges and CSS revenue from Change-over/Open Access consumers while setting retail tariff, and (iv) omission of certain applicability clauses under LT IV(B) Public Services-Others tariff category. This corrigendum was issued to record and correct these errors.
- Confirmed that AEML-D's Supply Business ARR for FY2023-24 should have been Rs.6561.30 Cr (after deducting Rs.47.48 Cr AEML-G surplus) but tariff was erroneously based on Rs.6608.78 Cr (surplus not deducted)
- Confirmed AEML-D's share of Rs.29.21 Cr Standby Charges refund (from TPC-G's approved Rs.87.63 Cr total refund) was inadvertently excluded from AEML-D's MTR Order
- Confirmed Rs.471.42 Cr (FY2023-24) and Rs.509.91 Cr (FY2024-25) of approved Wheeling Charges and CSS revenue from Changeover/Open Access consumers was not factored into retail tariff determination
- Directed that all above impacts (Sr.1-3) be addressed only in the true-up of the respective years in the next tariff determination process, consistent with past practice (per Case No.103 of 2020)
- Approved corrective insertion of omitted applicability clauses (items p-s: public street lighting, public gardens, traffic signals/islands, public water fountains) under LT IV(B) Public Services-Others category to align with the original MYT Order dated 30 March 2020
- No change made to current FY2023-24/FY2024-25 tariff schedules or amounts as a result of this corrigendum
- Impact of AEML-G surplus, Standby Charges refund, and Wheeling/CSS revenue mismatches to be reconciled in true-up filings for FY2023-24 and FY2024-25 in the next tariff cycle
- TPC-G directed (per Case 221 of 2022) to refund Rs.87.63 Cr total Standby Charges (incl. Rs.29.21 Cr to AEML-D) in April 2023
- Tariff Schedule for LT IV(B) Public Services-Others stands corrected with immediate effect to include omitted applicability clauses (streetlights, public gardens, traffic signals, water fountains)
- No revision to FY2023-24/FY2024-25 approved tariffs at this stage; corrections are procedural/accounting adjustments for future true-up
- Stakeholders should track AEML-D's subsequent true-up petition for actual pass-through of these adjustments
- Consumers under LT IV(B) category should verify billing aligns with restored applicability clauses
- • C&I open access and change-over consumers should note that Wheeling Charges/CSS revenue shortfalls (~Rs.471-510 Cr) are deferred to future true-up, meaning potential future tariff/surcharge adjustments rather than immediate relief
- • No immediate change to current FY2023-24/FY2024-25 retail tariffs for C&I consumers from this corrigendum; effective tariffs remain as per the original 31 March 2023 MTR Order
- • Entities in LT IV(B) Public Services-Others category (e.g., municipal/public lighting under C&I contracts) should confirm billing reflects restored applicability clauses
- • Open access and OA-CSS payers should monitor upcoming true-up proceedings, as under/over-recovery of Rs.471-510 Cr in wheeling/CSS revenue could affect future OA charges
This is a housekeeping corrigendum, not a tariff revision - it flags accounting/computation errors (surplus pass-through, standby refund, wheeling/CSS revenue) that MERC has chosen to reconcile only in future true-ups rather than reopening current tariffs. C&I and OA consumers see no immediate bill impact, but should watch AEML-D's next true-up filing closely as cumulative adjustments (potentially Rs.500+ Cr across two years) could influence future ARR and cross-subsidy surcharge trajectories. The LT IV(B) correction is minor and consumer-category specific.
