About PNG

MGL has the distinction of pioneering Natural Gas distribution network in Mumbai and its adjoining areas. Over 0.8 million domestic customers are connected through our wide network of over 4400 kms which comprises of carbon steel (CS) and polyethylene (PE) pipeline. Domestic PNG is used for various purposes like cooking and water heating. It is also widely used by Hospitals, Nursing Homes, Hotels, Flight kitchens, Restaurants, places of Worship etc. PNG satisfies most of the requirements for fuel across all segments, being efficient, non-polluting and relatively economical

Benefits of Piped Natural Gas

Piped Natural Gas is the preferred fuel. Here are some of the major benefits of using natural gas:

  • Convenience – Gas is continuously fed into the system so there are no hassles of refilling / changing the cylinder; it is piped and does not require any space to store, hence handling is easy, safe and secure.
  • Economical – Higher savings than any other conventional fuel.

  • Safe – Robust systems and processes as per international safety standards that match the best in the world, are practiced. PNG being lighter than air disperses easily and avoids spontaneous flammability.

  • Consistent, reliable supply – MGL has got a track record of almost 100% reliability in its gas supply. Even during the deluge of July 2005 in Mumbai, when most other utilities failed, PNG supply continued uninterrupted.

  • Eco-friendly – Use of PNG improves public health. It also reduces the transportation of bottled gas within the metro thereby reducing traffic congestion and safety on the roads.

PNG Composition

With only one carbon and four hydrogen atoms per molecule (Methane) Natural Gas is a composition of hydrocarbons (Almost 95% Methane & rest other Hydro Carbons).  Its calorific value generally ranges from 8000 kcal/m3 to 9000 kcal/m3, Natural Gas has the lowest carbon to hydrogen ratio, hence it burns completely, making it more environment friendly fuel.
