## THE MINISTER OF STATE IN THE MINISTRY OF POWER

(SHRI SHRIPAD NAIK)

(a) to (c): As per 'Resource Adequacy Plan (RAP)' prepared by State of Tamil Nadu in  consultation  with  Central  Electricity  Authority  (CEA)  for  the  period  till  2034-35, projected peak demand and annual energy consumption during financial year 2026-27 is envisaged as 23,314 MW and 1,62,726 MUs respectively.

To meet peak summer demand, TNEB Ltd. has taken several advance measures as under:

- (i) Tamil Nadu Power Distribution Corporation (TNPDCL) has concluded MediumTerm Power Procurement arrangements for about 2,700 MW for a period of five years and  Short-Term  Power  procurement  arrangements  for  about  3,500  MW  during  the months of March, April and May to meet the anticipated increase in summer demand.
- (ii) TNPDCL has entered into a power swap arrangement with Uttar Pradesh Power Corporation  Limited  (UPPCL)  for  500  MW  during  the  period  from  01.03.2026  to 15.04.2026.

(iii) Recently, the State has added 800 MW coal based thermal capacity i.e North Chennai Thermal Power Station Stage-III (800 MW) with Commercial Operation Date on 24.01.2026.  State  already  optimized  its  hydro  resources  during  the  months  of November, December and January, so that full hydro capacity is available during the high-demand summer months of March, April and May.

(iv) The State has added a total of 1,924 MVA of new substation Transformation capacity, 1,606 MVA of additional Transformation capacity in existing substations and 452 km of Transmission lines in FY 2025-26

In  addition  to  the  above,  state  of  Tamil  Nadu  had  requested  for  additional allocation of 1500 MW power. Subsequently, the Ministry of Power (MoP) has allocated 329.36 MW of firm power from the Farakka Super Thermal Power Station (Stage I & II) to Tamil Nadu in November, 2025, which is extended up to 31.05.2026 with view to ensure uninterrupted power in the state.

(d):  The details of power infrastructure development projects initiated by the State/ Central Government in Tamil Nadu are given below;

- (i) Generation:

There are four under construction thermal power projects of capacity 5,140 MW in the State of Tamil Nadu. The details are given at Annexure.

- (ii)  Transmission:

Currently  five  Inter  State  Transmission  System  (ISTS)  projects  are  under implementation in Tamil Nadu for integration of Renewable Energy (RE)/ non-fossil generation and grid-strengthening and its details are given below:

- (A) Transmission  System  under  ISTS  for  evacuation  of  power  from  Kudankulam Nuclear Power Plant (Unit-3& 4 - 2x1000MW).
- (B) Augmentation of 2x500 MVA, 400/230 kV transformation capacity 3 rd  &4 th  ICTs (Interconnecting Transformer)] at Karur Pooling Station.
- (C) Augmentation  of  Transformation  capacity  at  400/230KV  Tuticorin-II  GasInsulated Switchgear (GIS) Pooling Station in Tamil Nadu by 500 MVA, 400/230 KV ICT (6th).
- (D) Augmentation of 1x500 MVA, 400/230 kV ICT (7th) at Tuticorin-II GIS SubStation.
- (E) Augmentation of Transformation capacity by 1x500 MVA, 400/230 kV ICT (4th) at Kalivanthapattu s/s in Tamil Nadu.

Further, Ministry of New and Renewable Energy (MNRE) has approved Intra State Transmission System (In-STS) projects under Green Energy Corridor (GEC)-II Scheme in Tamil Nadu, which are being implemented by Tamil Nadu Transmission Corporation Limited (TANTRANSCO), the list of projects under GEC-II are given below:

- (A) 400 kV line associated with Samugarengapuram 400/230-110 kV SS (Sub Station)
- (B) 230/110 kV line associated with Samugarengapuram 400/230-110kV SS
- (C) Establishment of 230/110 kV Digital substation at Poolavady 230 kV SS.
- (D) 230/110 kV line associated with Poolavadi 230 kV SS
- (E) Establishment of 230/110 kV Substation at Muppandal
- (F) 230/110 kV line associated with Muppandal 230 kV SS

## (iii) Distribution:

With the objective of improving the quality and reliability of power supply to consumers through a financially sustainable and operationally efficient distribution  sector,  Government  of  India  launched  'Revamped  Distribution  Sector Scheme'  (RDSS)  in  July  2021.  A  key  objective  of  the  RDSS  is  to  reduce  the 'Aggregate Technical and Commercial' (AT&C) losses to pan-India levels of 12-15 % and the gap between 'Average Cost of Supply' (ACS) and 'Average Revenue Realized' (ARR)  to  Zero.  Under  the  scheme,  financial  assistance  is  being  provided  to  the eligible Distribution Utilities for upgradation of distribution infrastructure and smart metering works in the country including Tamil Nadu, for enhancing the efficiency of the distribution network and reduce losses in the system.

Under the RDSS Scheme, distribution infrastructure works of Rs 1.53 lakh crores and  smart  metering  works  of  Rs  1.31  lakh  crores  have  been  sanctioned  for  the country. Under this scheme, Rs 19,235 crore for smart metering projects and Rs 9,568  crore  for  distribution  infrastructure  works  have  been  sanctioned  for  Tamil Nadu  including  Vellore  Parliamentary  Constituency.  Following  power  distribution infrastructure works amounting to Rs 776 crore have been sanctioned in the Vellore Parliamentary Constituency under RDSS:

- (A) Agriculture Feeder Segregation (AFS): 54 number of feeders.
- (B) High Voltage Distribution System (HVDS): 10 number of feeders.
- (C) Separation of Double Distribution Transformer: 04 number of feeders.
- (D) Auxiliary cable for Distribution Transformers (DT): 9058 DTs.
- (E) Smart meters: 8,00,606 consumers, 9058 DTs and 213 feeders.
