## ANSWER

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

## (SHRI SHRIPAD YESSO NAIK)

(a)  to  f)  Government  of  India  has  notified  National  Electricity  Plan  (V olume-II Transmission)  in  2024, which  outlines  the  transmission  system  requirements  for  the  period  2023  to  2032,  including  the  states Karnataka, Chhattisgarh, Jharkhand, Rajasthan, Maharashtra and Jammu and Kashmir, commensurate with projected generation capacity additions to meet the projected electricity demand.

Further  following  measures  have  been  undertaken  by  the  Government  to  strengthen  transmission infrastructure, grid management and forecasting to facilitate integration of renewable energy into the grid while maintaining grid stability:

- i. Comprehensive Regulations and Standards governing interconnection and operations of renewable plants such as CEA (Central Electricity Authority) connectivity standards, flexible thermal plant operations, and the Indian Electricity Grid Code 2023;
- ii. Advanced grid support technologies such as STATCOMs and synchronous condensers for voltage stability and dynamic response have been considered in the transmission planning and are at various stages of implementation.
- iii. Establishment  of  Renewable  Energy  Management  Centers  (REMCs)  for  real-time  forecasting, scheduling, and monitoring of RE generation across 12 RE-rich regions.
- iv. Ministry of New and renewable energy is implementing Green Energy Corridor (GEC) scheme in ten states viz.,   Andhra Pradesh, Gujarat, Himachal Pradesh, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Rajasthan, Tamil Nadu and Uttar Pradesh.  A total of 9856 ckm transmission lines and 24, 300 MVA substation have been commissioned under GEC scheme.
- v. Regulatory framework for Solar Hour and Non-Solar Hour access enabling optimal utilisation of transmission and encouraging hybridisation with storage.
- vi. Implementing two Viability Gap Funding (VGF) schemes to support development of approximately 43.8 GWh of Battery Energy Storage Systems, launched in March 2024 and June 2025, to accelerate early-stage deployment.
- vii. As of 28.02.2026, a total of 13 Battery Energy Storage System (BESS) projects with an aggregate capacity of 798.20 MWh have been commissioned across the country. The present installed capacity of pumped storage projects in the country is 7175.6 MW.
- viii. Providing  budgetary  support  for  enabling  infrastructure  (Roads,  Transmission  lines  etc.)  for development of Hydro PSP.

Details of projects whose transmission system is delayed is placed at Annexure-I .
