ISLAMABAD - The transmission line carrying electricity from Iran developed a fault, resulting in a blackout of 10 hours in many areas of Balochistan yesterday.

As the line tripped at 6:45am, the fault was found in the mountains between Iran and Mand, Qesco officials said.

Mand is the first Pakistani station with 132KV grid station at Pak-Iran border and electricity is supplied through a main 132KV, 756km transmission line from Iran to Mand.

The second station is Tump and then the line passes through Hoshab, Panjgur and Turbat; from Turbat it connects Pasni and Gwadar.

The officials said the line was restored at 18:30 and 55MW electricity transmitted to the Quetta Supply Company.

According to the agreement, Iran supplies around 70MW electricity to Pakistan. However, the peak supply remains at around 65MW and minimum around 40MW.

The Ministry of Water and Power yesterday said the electricity supply to the rest of the country was normal and normal loadshedding was being carried out.

The normal predictable load management of six hours in urban areas and eight hours in rural areas is being carried out in the country except for the areas with high losses or high theft ratio, said Ministry of Water and Power officials.

They said it was wrong that the energy deficit was 5000MW. Peak generation is 13,658MW against its demand of 15,881MW, with a shortfall of around 2,300MW average, excluding Discos and NTDC constraints.

Peak generation is the maximum generation reached any time during 24 hours and does not reflect average generation. The officials did not mention the exact number of NTDC and Disco losses.

According to State Minister Abid Sher Ali, the NTDC constraints were around 1000MW.

The officials denied the loadshedding in the country had been increased, saying long blackouts in some areas do not reflect the whole country.
