TPCIL is a joint venture between Gayatri Energy Ventures, a wholly-owned subsidiary of Gayatri Projects, and the Singapore-based Sembcorp Utilities.
"Power being generated from 660-MW Phase II is also largely sold out to existing customers, and longer term arrangements are in the process of being firmed up," the company said in a press release.
According to the statement, the first phase of the about USD 1.5 billion coal-fired power plant, commissioned earlier this year, generated more than 800 million units during the quarter ended June 30.
"We are pleased to announce the successful commissioning of the second phase, which marks the completion of our maiden power project," Gayatri Projects MD T V Sandeep Kumar Reddy said in the statement.
