REFINERY SECTOR IN INDIA

The oil and gas sector is among the eight core industries in India, thus holding an influential position in the decision-making processes at the top government level that affect all other important sectors of the Indian economy. With a massive capacity 247.571 MMTPA, the Indian Refinery sector is next only to the US and China in global volumes. Within the country, the sector is the second-largest energy consumer. Of the total refining capacity, more than half comes from public sector refineries. India’s economic growth and demand for energy are strongly interlinked, and hence the forecast for growth in the refinery sector remains positive for several years in the future.

PAT SCHEME FOR THE REFINERY SECTOR

There are around 23 Petroleum refineries plants in India. Out of this PAT has covered 20 plants. However, these plants are the large plants which has the maximum energy consumption and has the maximum share in India’s total production. It is evident that the large producers which are also the large energy consumers in the sector has been covered under PAT as 87% of the plants the PAT scheme produces more than 94% of the total production in country.

PAT Cycles wise number of DCs, their total energy consumption (Million TOE) and energy savings targets (Million TOE) of the Refinery Sector are presented below:
