Construction of a 230 kilovolt gas-insulated substation started Sunday at the site of Rey Power Plant in south Tehran as the first step to phase out the old station, head of the Thermal Power Plants Holding Company said.
Estimated useful life of an electricity plant is 20 years but the Rey station has operated for half a century.
“It started working with 40 gas units and generation capacity of 1,170 megawatts,” Mohsen Tarztalab was quoted as saying by the Energy Ministry news portal Paven.
“However, due to old age, wear and tear and failure of some units, only 20 gas units are operating and output has dropped to 500 MW,” he said.
