G R Infraprojects has won REC Power Development and Consultancy’s (RECPDCL) transmission project to evacuate 2,500 MW of power from renewable energy projects in Rajgarh and Neemuch Special Economic Zones in Madhya Pradesh.

The tender was floated in March this year.

The annual transmission charges are ₹3.67 billion (~$42.67 million). The projects must be completed within 24 months from the date of acquisition of the special purpose vehicle. The operations and maintenance period will run for 35 years.

The scope of work includes the establishment of a 2×500 MVA, 400/220 kV substation at Handiya, equipped with two 125 MVAr 420 kV bus reactors. At Neemuch Power Station (PS), a new 220 kV Bus Section-II will be created, with augmentation of transformation capacity through three 500 MVA, 400/220 kV interconnecting transformers (ICTs) and the construction of four new 220 kV line bays for renewable energy interconnection.

Additionally, a new 220 kV Bus Section will be set up with a 220 kV Bus Sectionalizer, augmentation of transformation capacity through another set of three 500 MVA, 400/220 kV ICTs, and three 220 kV line bays for renewable energy interconnection.

The project also includes the installation of a 220 kV line bay for renewable energy interconnection for Purvah Green Power and a 1×125 MVAr, 420 kV bus reactor at Pachora PS (400 kV Bus Section-II).

Further works include four 400 kV line bays, two at Rajgarh (PG) and two at Pachora PS, along with four 420 kV switchable line reactors (two each at Rajgarh and Pachora), and four switching equipment units for the 400 kV line reactors.

Transmission line construction includes a 400 kV double-circuit (D/C) line with associated line bays and 50 MVAr switchable line reactors on each circuit at both ends. Additional 400 kV D/C lines of similar specifications will be built with associated line bays at Pachora PS and Handiya substation, including a 400 kV D/C (Twin Moose) line at Handiya substation.

The project, titled “Transmission system for Evacuation of Power from RE Projects in Rajgarh (1500 MW) SEZ in Madhya Pradesh-Phase III and Evacuation of Power from RE Projects in Neemuch (1000 MW) SEZ in Madhya Pradesh-Phase II,” will be implemented on a build, own, operate, transfer basis.

Last December, G R Infraprojects was awarded a contract from PFC Consulting to establish an inter-state transmission system to integrate the Bijapur Renewable Energy Zone in Karnataka.
