## THE MINISTER OF STATE IN THE MINISTRY OF POWER

(SHRI SHRIPAD NAIK)

(a) : The present installed capacity of Battery Energy Storage Systems (BESS) projects (more than 1 MWh capacity) in the country is 204.5 MW (505.6 MWh). The details are at Annexure.

(b) : Major components of BESS like Cells and Battery Management System are currently based on imported technology.

……2.

(c) : For encouraging BESS across the States, the Government has, interalia, undertaken the following measures:

- i. Inclusion of Energy Storage System (ESS) in harmonized master list of infrastructure.
2. (ii) Incorporating ESS as an element of procurement planning
3. (iii) Issuing standard bidding guidelines for procurement and utilization of  BESS  as  part  of  Generation,  Transmission  ,  Distribution  or Ancillary Services.
4. (iv) Waiver of Inter-State Transmission (ISTS) charges for 12 years for co-located BESS projects to be commissioned by June 2028. For non-co-located BESS, 100% waiver for projects which are commissioned  by  June  2025,  and  thereafter  graded  reduction  in waiver at the rate of 25% annually.
5. (v) Implementation  of  Viability  Gap  Funding  (VGF)  schemes  for  the development of about 43.2 GWh of BESS capacity in the country.

(d) : CEA  has  issued  draft  Central  Electricity  Authority  (Measures relating to Safety and Electric Supply) (First Amendment) Regulations, 2025 on 19.06.2025 for stakeholders' comments, which covers safety requirements for BESS.
