Adani Energy Solutions has been selected by PFC Consulting to develop the interstate transmission system (ISTS) for the drawal of power from the South Kalamb substation: Part A in Maharashtra.

While not a standalone renewable energy evacuation project, the ISTS is linked to a broader transmission system that evacuates power from the Rajasthan REZ Phase IV (Barmer complex), which comprises 6 GW of solar capacity. The project is intended to disperse further the power received at South Kalamb from this upstream system.

The scope of work includes augmenting the transformation capacity at the South Kalamb substation by installing three 1500 MVA, 765/400 kV interconnecting transformers, along with associated 765 kV and 400 kV bays and bus sectionalisation.

The project also involves installing bus reactors for reactive power support and implementing line-in-line-out across multiple 400 kV transmission lines, including the Nagothane–Padghe and Pune–Mumbai corridors, along with associated line bays and substation works to facilitate reliable power flow and network integration.

The project will be implemented under the build, own, operate, and transfer model.

The work must be completed within 24 months of the transfer of the special-purpose vehicle.

The tender was issued in September last year.

In February, AESL secured long-term financing from a consortium of Japanese banks, led by MUFG Bank and Sumitomo Mitsui Banking Corporation, for its ±800 kV high-voltage direct current transmission project to evacuate 6,000 MW of solar energy from Bhadla, Rajasthan, to Fatehpur, Uttar Pradesh.

Last year, Adani Energy won several transmission projects. It received a letter of intent from PFC Consulting to establish a transmission system to evacuate 2.5 GW of energy from a potential renewable energy zone in Khavda, Gujarat, under Phase V (8 GW): Part C.

It also bagged REC Power Development and Consultancy’s transmission project to evacuate 1.5 GW of power from pumped storage projects near Talegaon, Maharashtra.
