The company says in a statement posted on its website that the agreement with the Afghan Water and Power Ministry was signed on August 31.
The Naglu plant, which is located on the Kabul River west of Jalalabad, was built by Tekhnopromexport -- then a Soviet company -- in the late 1970s.
The company says it built another three hydroelectric plants in Afghanistan during the Soviet era.
Tekhnopromexport says the $32 million contract to modernize the Naglu plant will be funded by a World Bank credit to the Afghan government.
