## MINISTER OF STATE IN THE MINISTRY OF PETROLEUM AND NATURAL GAS (SHRI SURESH GOPI)

(a)  to  (c)  Natural  gas  is  supplied  through  a  network  of  natural  gas  pipelines  and  through  City  Gas Distribution (CGD) Network. Petroleum & Natural Gas Regulatory Board (PNGRB) is the authority to grant authorization to the entities to lay, build, operate or expand Gas Pipeline as per PNGRB Act, 2006. The status  of  operational  as  well  as  under  construction/  partially  commissioned  natural  gas  pipelines passing through the state of Tamil Nadu is at Annexure-I.

Providing  Piped  Natural  Gas  (PNG)  connections,  establishment  of  Compressed  Natural  Gas  (CNG) stations  and  laying  of  pipeline  infrastructure  is  part  of  development  of  City  Gas  Distribution  (CGD) Networks and the same is carried out by the entities authorized by PNGRB, as per their Minimum Work Programme (MWP).

In the state of Tamil Nadu, PNGRB has authorized 18 Geographical Areas (GAs) (1 GA spread over Puducherry (UT) & Tamil Nadu and 1 GA spread over Andhra Pradesh, Tamil Nadu and Karnataka) covering  all  the  districts  in  the  state.  The  GA-wise  details  of  MWP  targets  and  achievement  for establishing CGD networks in the state of Tamil Nadu, as on 31.12.2025, is at Annexure-II .
