kV bus reactor and 2x125 MVAR, 420 kV bus reactor alongwith LILO of Pune-III – Boisar-II 765
kV D/c line (presently under bidding stage).
* Network Expansion Scheme: Creation of New 765 kV & 400 kV Bus Sections-II & III through
765 kV Sectionalization bay: 2 sets & 400 kV Sectionalization bay: 2 sets alongwith 2x330
MVAR, 765 kV bus reactor & 2x125 MVAR, 420 kV bus reactor on Section-III is being proposed
along with ICT augmentation (3x1500 MVA, 765/400 kV ICTs) at Bus Section -III at both 765
kV & 400 kV levels alongwith downstream 400 kV lines at bus section-III from South Kalamb S/s
with implementation timeframe of 24 months from effective date. [400 kV Sectionaliser between
Sections-I & II & between sections-II & III to be normally open. Further, 765 kV sectionaliser
between Sections-I & II & between II & III shall be kept normally closed. The 400 kV
sectionalisers can be closed under contingency conditions.].
** The above are as per discussions with OEMs and the under-excitation limit is as considered by
the committee formed under Chairmanship of Member Secretary, NRPC along with members from
CEA, NLDC, NRLDC, NTPC, BHEL, CTU and STUs to do futuristic analysis for requirement of
Synchronous Condensers based on the inertia considerations for Northern Region
2. The appointment of the Bid Process Coordinator is subject to the conditions laid down in the Guidelines issued
by Ministry of Power in this regard, amended from time to time.
3. BPCs shall ensure RoW optimization as per the CEA's Committee report dated 24.09.2024 for calculation of
reduction of Right of Way (RoW) Width through Technological Options.
4. Further, the route must be finalised after validation on PM Gati Shakti portal and physical survey.
