A day after announcing it planned to issue 17 million new shares of stock, Cheniere Energy Inc. increased the offering to 21 million shares at $15.10.

Houston-based Cheniere has announced it plans to build a multibillion-dollar natural gas liquefaction facility in Cameron Parish. Last month, Cheniere has secured $2 billion in financing for the facility, which is expected to begin operating in 2016.

The company said it expects to close the stock offering on Monday. Cheniere is also offering underwriter Credit Suiess Securities LLC a 30-day option to buy up to 3.15 million additional shares to cover any share sales over the 21 million offering.

The company intends to use the money from the stock sale, $317 million before expenses, for general corporate purposes including paying down debt.
