Power Grid Corporation of India Ltd (PGCIL) has been nominated to implement two interstate transmission system (ISTS) projects with an aggregate outlay of Rs.420.28 crore, under the regulated tariff mechanism (RTM) route.
The National Committee on Transmission (NCT), in its most recent meeting held on August 23, 2024, approved the following two projects, to be implemented by PGCIL on RTM basis:
Scheme: Eastern Region Expansion Scheme – 43 (ERES-43)
Cost: Rs.310.28 crore
Implementation period: 18 months (15 months on best effort basis)
Scheme: Additional transmission system proposed for redundant power supply of Dholera area
Cost: Rs.110 crore
Implementation period: 18 months
The ERES-43 scheme involves upgrade to transmission assets associated with NTPC’s Kahalgaon (Bihar), Farakka (West Bengal) and Talcher (Odisha) power plants, as well as the Meramundali substation of Odisha Power Transmission Corporation Ltd (OPTCL). The scheme envisages re-conductoring of the 400kV double-circuit Kahalgaon – Farakka line, and the 400kV double-circuit Talcher – Meramundali line. Besides, upgrade of 400kV bay equipment at the Kahalgaon, Farakka, Talcher and Meramundali substations.
The Dholera project (discussed in detail in T&D India’s story dated August 30, 2024) involves creation of a 220kV switchyard along with installation of 2×500 MVA, 400/220kV ICTs at the upcoming Vataman AIS substation in Gujarat, and two 220kV line bays for the 220kV double-circuit Vataman – Dholera-2 line of Gujarat Energy Transmission Corporation Ltd (GETCO). This project, costing Rs.110 crore, has an envisaged completion timeframe of 18 months.
As explained in the previous story, the overall Dholera transmission scheme has two components. The RTM project discussed above represents the second component.
The first component will entail creation of a 400kV switchyard along with installation of 2×1500 MVA, 765/400kV interconnecting transformers at the Vataman (AIS) substation. This component will be developed through an RTM scheme of PGCIL, which has been approved earlier, and is called “Transmission system for offshore wind zone Phase-I (500 MW VGF off coast of Gujarat for subzone B3”
