Repair work at South Cyprus Vassilikos power station will be completed by August.
The largest power plant in the South was severely damaged in July 2011, when containers of seized Iranian munitions, being stored at the Evangelos Florakis naval base in Mari, blew up.
Thirteen people were killed in the blast.
The Minister of Commerce, Industry and Tourism George Lakkotrypis, yesterday visited the Station, to mark the reopening of Power Units No. 1 and No. 3.
Last year, the former president of Cyprus was blamed by an official investigator for negligence leading to the explosion.
Polys Polyviou said that former President Christofias bore a “serious, and very heavy personal responsibility” for the blast.
