Shahid Rajaee Power Plant
History and background
Basic studies of power station, as a part of Shahid Rajaee Project, began by the Mahab Qoads Consultant and Electrowatt Stoki Co. of Sweden since 1989 together with the studies of dam body. The second phase studies were completed in 1994. The capacity of this project is 13.5 MW (three units of 4.5 MW). In the middle of 2000 this project was taken from Regional Water Organization of Mazandaran and handed over to Iran Water and power resources Development Co. The studies of technical documents and preparing tender documents continued with cooperation of Mahab Qods Co. In the second half of 2001 Pajuhab Co, as the project consultant and then Armetab Co. as the civil contractor and Mabna Niroo Co. as the contractor of preparing, manufacturing and installation of switchyard equipments were elected through tendering and their activities began in March 2002. In July 2002 due to an earthquake in the region the main part of these activities came to a halt. In February 2004 the main contract of project was concluded with Farab Co. and up to now the project’s different phases are being implemented.
