Reliance Power keeps exploring various business opportunities. The company would not like to comment on specific business proposal, the utility said in an e-mail response to Reuters.
A Shell India spokeswoman did not respond to phone calls seeking comment.
Reliance Power is holding talks with Shell to form a joint venture in which the two companies will hold equal stake and Kakinada port in the southern Andhra Pradesh state will own a minority stake, the source with knowledge of the matter said.
The proposed venture will likely invest 30 billion rupees($564.92 million) to set up an LNG terminal at Kakinada on India's east coast and would import and supply gas initially to Reliance Power's 2400-megawatt, gas-fired plant in Andhra Pradesh, slated to come onstream in 2012, the source said.
