India: The Eastern Region System Strengthening Scheme (ERSS)—XXI, implemented by PGCIL under the TBCB route, is on the way to full completion.
According to a latest status report by Central Electricity Authority (CEA), ERSS-XXI, several components of which have already been commissioned, is scheduled for full completion by end of September 2021.
ERSS-XXI is being developed by Power Grid Corporation of India Ltd (PGCIL), under the tariff-based competitive bidding (TBCB) route, by its wholly-owned subsidiary “Powergrid Mithilanchal Transmission Ltd”, which, incidentally, was incorporated by the bid process coordinator as “ERSS XXI Transmission Ltd.”
ERSS-XXI, with an estimated outlay of around $176 M (Rs 1,300 crore), has several components – transmission lines and substations.
The unfinished portion of ERSS-XXI mainly includes a new substation at Saharsa in Bihar. The construction contract for this 400/220/132 kV, (2×500 MVA + 3×200 MVA) substation was awarded to Hitachi ABB Power Grids in India. Initially scheduled to commission in March this year, the substation project was hampered by pandemic-induced restrictions. As of 31 August 2021, civil work to the extent of 99 % and equipment erection worth 95 % was complete.
Another project element is physically complete but will be commissioned along with the aforementioned Saharsa substation. The element in question is the LILO of Kishanganj-Patna 400 kV D/C line at Saharsa (new) substation.
Incidentally, commissioning of the Chandauti substation was recently announced by project contractor Linxon. The substation was commissioned in March 2021 though.
