REC Power Distribution Company Limited (REC PDCL) has transferred Mahan Transmission Limited, a special purpose vehicle (SPV), to Adani Energy Solutions Limited (AESL).
The handover, completed on March 26, 2025, follows a tariff-based competitive bidding (TBCB) process for selecting a transmission service provider (TSP). The project will be developed under the build, own, operate, and transfer (BOOT) model.
The transmission system will evacuate 1,230 MW of power from the 2×800 MW thermal power project of Mahan Energen Limited through the state transmission utility (STU) network of Madhya Pradesh Power Transmission Company Limited (MPPTCL). REC PDCL, acting as the bid process coordinator, invited Request for Proposal (RFP) bids for the project in November 2024.
In February, four companies qualified as bidders after the opening of technical bids. These included Power Grid Corporation of India Ltd (PGCIL), AESL, Megha Engineering & Infrastructures Ltd (MEIL), and KCC Buildcon Pvt Ltd. AESL emerged as the final winner.
Project details
The transmission system will involve major infrastructure developments to facilitate power evacuation from the Mahan Energen plant.
At Rewa (Sagra):
- A 400/220/132 kV substation will be developed with transformers, switchable reactors, and multiple line bays.
- A 400 kV double-circuit double-string (DCDS) transmission line will connect the PTEMPL (MEL) Switchyard to Rewa (Sagra).
- The Rewa-Sirmour/Bansagar-I 220 kV line will undergo a loop-in loop-out (LILO) at Rewa (Sagra).
- A 220 kV DCDS line will be laid between Rewa (Sagra) and Kotar, along with multiple 132 kV interconnecting lines connecting Rewa (Sagra) to MPPTCL substations.
At Amarpatan:
- A 400/220/132 kV substation will be built with transformers, reactors, and multiple line bays.
- A 400 kV DCDS line will connect Rewa (Sagra) and Amarpatan.
- The Maihar-Satna (PGCIL) 220 kV line will have a LILO arrangement at Amarpatan.
- Multiple 132 kV lines will link Amarpatan with substations at Satna-II, Rampur Baghelan, and Unchehra.
The project is expected to strengthen the power evacuation infrastructure in Madhya Pradesh, ensuring efficient transmission from the upcoming thermal power plant.
