RPT-Kazakhstan says AES underinvested in power plants

ASTANA, April 30 (Reuters) - Kazakhstan on Friday accused U.S. firm AES (AES.N) of failing to invest $460 million into its power plants in the Central Asian country as required by contract, a charge the company has denied.

"AES has failed to meet investment pledges worth $459.52 million," a spokeswoman for the Kazakh anti-monopoly agency said.

A spokesman for AES denied the allegations.

"AES is meeting its investment pledges and does not plan to stop investing in Kazakhstan," said AES spokesman Alexei Bendz. (Reporting by Rausan Nurshayeva and Olga Orininskaya; Writing by Olzhas Auyezov, editing by Gleb Bryanski)
