Power Grid Corporation of India (POWEGRID) has received a letter of intent from PFC Consulting to establish an interstate transmission system (ISTS) at Kurnool-III PS, Andhra Pradesh, to integrate 4.5 GW of renewable energy.

The project comprises augmentation of transformation capacity at the existing Kurnool-III substation and extension works at the existing C’peta substation along with a 765 kV direct current transmission line.

The scope of work includes establishing, operating, and maintaining the project on a build, own, operate, and transfer. It also consists of survey, detailed project report formulation, arranging finance, project management, consents, clearances, permits, land compensation, design, engineering, equipment, material, construction, erection, testing, and commissioning.

The actual location of the substations, switching stations, high-voltage direct current terminals, or inverter stations must not lie beyond a 3 km radius of the area proposed in the survey report.

The tender was issued in September last year.

POWERGRID recently received letters of intent for three transmission projects from REC Power Development and Consultancy (RECPDCL) cumulatively worth ₹107.5 billion (~$1.2 billion). The three projects are a transmission system for power evacuation from the Rajasthan Renewable Energy Zone (REZ) Ph-V, an augmentation of transformation capacity at Banaskantha, Gujarat, and another transmission system project for integration of Kurnool-IV REZ Phase-I in Andhra Pradesh.

POWERGRID also won two projects from RECPDCL to establish an ISTS and augment substation capacity in Gujarat and Karnataka. The project involved augmenting the transformation capacity at the KPS1 and KPS2 (Phase-V Part B1 and B2) projects in Gujarat and augmenting the transformation capacity at the Bidar PS in Karnataka by 3×500 MVA, 400/220kV ICTs (6th – 8th) and 1×1500 MVA, 765/400kV ICT (4th).

In December last year, POWERGRID won a project from RECPDCL to establish an ISTS to evacuate 8 GW of renewable energy from Gujarat. The project will evacuate power from the potential REZ in the Khavda area under Phase-V (8 GW): Part A.
