Sterlite Industries and Suzlon Energy are reportedly planning to raise up to $1 billion in a month's time. While Suzlon plans to raise around $400 million, Sterling is planning to raise anything between $500 million and $1 billion.
While Suzlon is looking to retire debt, Sterlite will use the funds to finance expansion.
The companies had organised road shows earlier in this connection.
Sterlite Industries, a part of Vedanta Resources, had last month taken shareholder's approval for issuing securities or global or American depositary receipts or convertible bonds.
Standard & Poor has recently placed the company on a credit watch. (See: Standard & Poor places Vedanta on CreditWatch)
