MERC approved AEML-D's FY22-24 truing-up, FY24-25 provisional truing-up, and ARR/tariff for 5th Control Period FY2025-26 to FY2029-30, with revised tariff design, kVAh billing expansion and new rebates
Case of Adani Electricity Mumbai Limited (Distribution Business) for Approval of Truing-up of FY 2022-23 and FY 2023-24, Provisional Truing-up for FY 2024-25, and ARR and Tariff for 5th Control Period from FY 2025-26 to FY 2029-30
AEML-D filed a petition on 30 Nov 2024 (revised 6 Jan 2025) under the MYT Regulations 2024 seeking Commission approval of truing-up of ARR for FY2022-23 and FY2023-24, provisional truing-up for FY2024-25, and determination of ARR and category-wise tariffs for the 5th Control Period (FY2025-26 to FY2029-30). The petition also proposed category rationalisation, kVAh billing extension, single-part EV tariff, bulk consumption rebates and a revised Green Tariff, following public consultation and stakeholder objections on tariff hikes, categorisation and billing methodology.
- Approved truing-up of ARR for FY2022-23 & FY2023-24, provisional truing-up for FY2024-25, and ARR/tariff for the 5th Control Period FY2025-26 to FY2029-30
- Extended kVAh billing to all LT consumers with load >20kW (excluding BPL, LT-I Residential, LT II(a)/III(a)/IV up to 20kW, LT V Agriculture, LT VI EV ≤20kW), effective 1 April 2025
- Renamed Fuel Adjustment Charge (FAC) to Power Purchase Cost Adjustment (PPCA) to reflect its actual scope across all power sources
- Approved single-part tariff (only energy + wheeling charge, no fixed charge) for HT/LT EV Charging Stations per MoP Guidelines 2024
- Introduced reverse-telescopic Bulk Consumption Rebate for EHT/HT-Industrial consumers: 2% (>1 lakh-1 MU/month), 1.5% (>1-5 MU/month), 1% (>5 MU/month) on energy charge
- Re-categorised District Cooling Solutions, Hotels/Resorts/Service Apartments under Industry tariff, and approved a graded Advance Payment discount scheme and revised cross-subsidy trajectory (FY25-26 to FY29-30)
- AEML-D to complete metering compatibility for kVAh billing for all consumers, including changeover consumers, within 3 months of the order
- AEML-D to file segregated data on LT Public Service and EV Charging Station consumers (load <20kW/>20kW) in the next MTR petition
- New energy charges, wheeling charges and cross-subsidy trajectory to apply from 1 April 2025, with pre-approved annual revisions through FY2029-30
- AEML-D to operationalise the Bulk Consumption Rebate and graded Advance Payment discount scheme in billing systems
- AEML-D to install appropriate incomer meters to enable netting-off of regenerative braking energy from Metro trains
- AEML-D to update tariff schedule to reflect revised categorisation of DCS, hotels/resorts/service apartments, and effluent/sewage treatment plants
- • HT/LT Industrial and Commercial consumers see a sharp tariff step-down in FY25-26 versus FY24-25 followed by gradual annual increases through FY29-30 — budget multi-year cost trajectories accordingly
- • Bulk Consumption Rebate (up to 2%) directly benefits large-load HT-Industrial consumers (>1 lakh units/month) such as factories and data centres, lowering effective energy cost
- • kVAh billing now applies to most LT consumers >20kW from 1 April 2025 — C&I open-access and captive users must monitor power factor closely to avoid billing distortions
- • District Cooling Solutions, hotels/resorts/service apartments moved to Industry tariff and EV charging stations get a no-fixed-charge single-part tariff — favorable for such developers and EV infrastructure investors
This order signals MERC's push toward simplified, cost-reflective tariffs and consumption-linked incentives (bulk rebate, advance payment discount) that reward large, steady C&I loads. The kVAh billing rollout raises power-factor management stakes for open-access and captive consumers on AEML-D's network. Developers in DCS, hospitality and EV charging should reassess category classification benefits immediately, while C&I buyers should model the full FY25-30 tariff trajectory rather than anchor only on the FY25-26 dip.
