The World Bank announced last week the India will receive a loan of $400 million, the largest ever made by the organization, for an energy project.

The loan will help finance the foreign exchange cost of the development of the Bombay High oil and gas field, about 100 miles from Bombay.

The bank said the $823.2 million project will help complete the development of the southern and central areas of the Bombay High field, and thus help it achieve a production potential of 240,000 barrels a day by mid-1982.

The World Bank and an affiliate, the International Development Association, have been involved in the development of India's energy sector since 1950, the announcement said. The two institutions have made 20 loans and credits totaling $1.5 billion for power generation and transmission and two loans totaling $47.4 million for coal production.
