## ANSWER

## THE MINISTER OF  STATE  FOR NEW & RENEWABLE ENERGY AND POWER

## (SHRI SHRIPAD YESSO NAIK)

(a) The Union Government is closely monitoring the implementation of the Green Energy Corridor (GEC) PhaseII including Tamil Nadu. Central Electricity Authority (CEA) is entrusted with monitoring of the projects and to ensure that the projects follow all the norms (including safety standards) prescribed by Central Government and State Government. All the State Transmission Utilities (STUs)  submit monthly progress report to MNRE.

Additionally,  MNRE  is  reviewing  the  progress  through  Project Appraisal  Committee  (PAC)  meetings    with respective state officials to assess the challenges and accelerate implementation.

(b) Under Green Energy Corridor (GEC) Phase-II, a project has been sanctioned to Tamil Nadu for evacuation of approximately 4000 MW renewable energy capacity. The project includes construction of 624 circuit kilometres (ckm) of transmission lines and 2200 MVA substation capacity. The total estimated project cost is ₹719.76 crore, with Central Financial Assistance (CFA) of 33% of the project cost. Tamil Nadu Transmission Corporation Limited (TANTRANSCO) is the implementing agency for the project and has divided the project into 9 packages.

(c)&(d) Details of total installed renewable energy capacity (including grid connected) as on 30.06.2025 in the state of Tamil Nadu is as under:

## ( In MW)

|   Small Hydro Power |   Wind Power |   Bio Power | Solar Power   |   Large Hydro |   Total |
|---------------------|--------------|-------------|---------------|---------------|---------|
|              123.05 |      11830.4 |     1046.62 | 10570. 88     |        2178.2 | 25749.1 |

The  State  of Tamil  Nadu  is  well  connected  with  National  Grid  through  high  capacity  transmission  corridors comprising 765kV & 400kV lines as well as +800kV HVDC System which facilitates smooth transfer of power through Inter State Transmission System (ISTS) network between Tamil Nadu and other States/Region. Power transfer capacities are being strengthened on a continual basis to address  changed power transfer scenarios as and when the requirement arises, with reliability & security.
