Lalit Kumar Gupta, Managing Director,Essar Oil informed thatthe company's Vadinar refinerywould reach 400,000 bpd capacity in September.      
 
 The company recently raised capacity of the refinery to around 360,000 barrels per day from 280,000 bpd.The firm also added units that can process cheaper, heavier crude into fuels.    
 
 Reports suggest that the increasing of capacity may increase margins of the firm by up to $5 a barrel and add nearly three quarters of a billion dollars to its annual revenues.
 
 The refinery would gain another $1 a barrel in margins through using a coal-fired power plant to provide electricity, which would save on fuel costs.
 
 Essar had earlier forecast a 35 percent jump in revenues for the fiscal year that started on April 1. Revenues for the previous fiscal year were around $9.5 billion.
 Essar plans to sell a stake of around 15 percent by June 2013, as required by India's market regulator to reduce the stake held by founding shareholders to 75 percent from nearly 90 percent now.
