MERC approved final/provisional true-ups (FY19-20 to FY22-23) and set AEML-G's ARR/Tariff at ₹1,845.26 Cr (FY23-24) and ₹1,816.81 Cr (FY24-25), effective 1 April 2023
Petition of Adani Electricity Mumbai Ltd.-Generation for approval of final Truing-up of Aggregate Revenue Requirement (ARR) for FY 2019-20, FY 2020-21 and FY 2021-22, Provisional Truing-up of ARR for FY 2022-23 and determination of revised ARR and Tariff for FY 2023-24 to FY 2024-25
AEML-G, operating Dahanu Thermal Power Station (ADTPS) and selling power to AEML-D under a PPA, filed a Mid-Term Review petition seeking final truing-up of ARR for FY2019-20 to FY2021-22, provisional truing-up for FY2022-23, and determination of revised ARR/Tariff for FY2023-24 and FY2024-25 under the 4th MYT Control Period, per MERC's 2015 and 2019 MYT Regulations. Key issues examined included coal costs (domestic and imported), GCV/transit losses, PLF norms, capex delays, forex hedging for imported coal, and PPA extension with AEML-D expiring mid-control period.
- Approved ARR of ₹1,845.26 Crore for FY2023-24 and ₹1,816.81 Crore for FY2024-25 (against AEML-G's claim of ₹1,908.39 Cr and ₹1,818.73 Cr respectively)
- Approved AFC of ₹365.35 Crore for FY2023-24 and ₹376.33 Crore for FY2024-25
- Approved Energy Charge of ₹4.017/kWh for FY2023-24 and ₹3.916/kWh for FY2024-25
- Computed a Net Revenue Surplus of ₹(47.48) Crore from past periods, to be adjusted in AEML-D's ARR (with carrying cost) rather than AEML-G's standalone AFC
- Approved full recovery of AFC as ADTPS availability exceeded the 85% normative threshold; capacity charges to be billed per Regulation 50(A) across High/Low Demand Seasons and Peak/Off-Peak hours as declared by SLDC
- Confirmed PPA extension between AEML-G and AEML-D till 15 October 2024 or commissioning of successful RE-RTC bidder, whichever is earlier (per Case No. 32 of 2022)
- AEML-G to appoint a nodal person with a time-bound plan to resolve pending credit/debit note settlements with SECL and report to Commission within 3 months
- AEML-G to complete all delayed DPR schemes approved between FY2010-11 and FY2013-14 by end of FY2023-24; no further extensions or capitalisation allowed thereafter
- AEML-G to submit detailed analysis of GCV drop in washed coal (below 4000 kcal/kg) at the time of FY2022-23 true-up
- AEML-G to justify deviations in actual Fuel Utilisation Plan vs. approved plan at FY2022-23 to FY2024-25 true-up
- AEML-G to provide cost-benefit justification for importing coal via Dahej Port vs. Dahanu Port, including contractual liability under Taurus Commodities agreement
- AEML-G to segregate CAPEX schemes from R&M expenses strictly per MYT Regulations while presenting future truing-ups
- • AEML-D's power procurement cost from AEML-G (embedded generation) is now fixed for FY23-24/24-25, which will feed into AEML-D's retail tariff for Mumbai C&I consumers via ARR pass-through
- • PPA extension only till Oct 2024 signals imminent competitive RE-RTC procurement (1000 MW solicited in Case 32/2022), opening avenues for RE/storage developers to bid into AEML-D's future power portfolio
- • Past period surplus (₹47.48 Cr) being passed to AEML-D's ARR rather than netted at generation level means consumers should watch AEML-D's subsequent tariff order for the pass-through benefit
- • Regulatory scrutiny on delayed capex, forex hedging and coal sourcing sets precedent relevant to other embedded/generation-linked open access arrangements in Mumbai license area
This is largely a technical true-up/tariff order for a single embedded generator supplying AEML-D, not a broad market or open-access ruling. For C&I buyers, the direct relevance lies in the PPA sunset date (Oct 2024) and the parallel 1000 MW RE-RTC competitive bidding by AEML-D — that process, not this order, is where new procurement and open-access opportunities will emerge. Track AEML-D's ARR filing to see how this generation cost and past surplus flow into retail tariffs.
