Tehran's Decrepit Power Grid Causes Blackouts

The decrepit power distribution network is a major factor contributing to soaring electricity blackouts in the capital Tehran, a member of Iran Electricity Industry Syndicate said.
"A part of Tehran's power grid went on stream in 1973 when the city's population stood at 4 million," Alireza Kolahi was also quoted as saying by Mehr News Agency. 
According to the official, the Energy Ministry has made major investments in electricity infrastructure, yet it has been oblivious to renovating the age-old distribution grid.
