of Rey power plant improvement project in the ceremony of starting the
executive operation of construction of 230 kV GIS substation of Rey power
plant, emphasizing that this substation has 14 230 kV feeders, continued: with
the implementation of this project, the first step will be taken to create the
necessary ground for the construction of a new Rey combined cycle power plant
with an efficiency of about 60% and the retirement of the old units of this
complex with a low efficiency of about 20%.
Noting that the project will be operational within 18 months, he

the volume of foreign exchange investment of this project is about 11 million
Euros and the amount of investment of the Rial part of this project will be 67

of Ray power plant, he said: due to the sensitivity and special position of
this power plant in Tehran province and the country's electricity network, and
due to the critical nature of the power plant substation in the construction of
new units, the implementation of this project is urgently on the agenda of the
thermal power company.
He continued: "For various reasons, including the lack of
sufficient space in the current power plant, the existence of various equipment
and buildings in different parts of the power plant, the 50-year-old existing
air post, the wear of high-pressure equipment and protection system, this
project will be implemented.
Referring to the specifications of this project, he said: "The
GIS substation is designed with a double busbar arrangement with a bypass disconnector
and consists of 6 230 kV line feeders, three feeders for new power plant units,
one feeder for Mitsubishi units and three transformer feeders are 230 to 63 kV,
which provides part of the load required by the Tehran refinery and industrial,
commercial and domestic consumption of the region.
