| Cross-subsidy surcharge (HT commercial & industrial) Same rate at EHV and at 33/22/11 kV (₹2.07/kVAh). The MYT order had ₹1.79 at EHV for FY 2026-27; the 25-Mar-2026 order replaced it before it took effect. |
₹2.11/kWh | 01 Apr 2026 → 31 Mar 2027 | Regulator document | MERC order in Case No. 75 of 2025 dated 25-Mar-2026 |
| Additional surcharge MERC did not approve an additional surcharge for the 5th control period (para 7.36.28). GEOA consumers paying fixed charges are exempt anyway (DOA 2nd Amendment, Reg. 7). In Case 75 of 2025 a developer alleged MSEDCL bills AS to group captive users; check actual bills. |

How to read the confidence labels
- Regulator document read from the regulator's or licensee's own published order
- Order reported the order is identified, and the value is confirmed by two or more trade reports of it
- Being verified from a secondary summary; being checked against the order
- Assumption an engineering or market default, not a regulated value
- Not loaded not yet in our library; our calculator warns when it is used
Wheeling charges and losses apply only to consumers supplied below the state's EHV threshold (66 kV in the states shown). Transmission charges billed per MW per day are converted to ₹ per unit in our calculator using the plant's capacity factor.
