DUBAI - Abu Dhabi National Energy Company, known as TAQA, has mandated banks ahead of a possible dual-tranche U.S. dollar-denominated green bond issue, a document showed on Thursday.

The integrated utility firm plans to hold investor calls starting April 13 and a benchmark-sized long 5-year issue and a 10-year green bond may follow. Benchmark-sized is typically at least $500 million.
