Yearly review of Iran's power sector

Iran's power sector passed a milestone year in terms of replacing liquid fuels by natural gas as fuel.
The latest weekly report of Iran's Energy Ministry, published on its official website on March 15 says the country's power plants were supplied with 53.5 billion cubic meters (bcm) of natural gas during 350 days of the current fiscal year, or 16.4 percent more than in the same period last year (Iran's fiscal year will end on March 20).
On the other hand, diesel and mazut consumption in electricity sector has decreased by more than 31 .3 percent and 31.6 percent respectively to around 5.7 billion liters and 6.7 billion liters in the mentioned period.
The country's total power production capacity also stood at 73,933 megawatts (MW), about 781 MW more than the previous year. The growth is far less that the targeted plan, which predicted at the beginning of the current fiscal year that the country's power growth would experience a 5-percent growth.
Iran has generated 270.5 billion kilowatt-hour (kWh) of electricity energy and the net exports reached 5.58 billion kWh.

The share of each type of power plants in the total generation capacity almost remained the same year-to-year. It shows that the country has failed to realize the plan of converting steam and gas power plants (with around 30 percent efficiency) to the combined-cycle ones (with 40-45 percent efficiency) during the current year.
None of the power plants which inaugurated during current year, is a combined-cycle.
The electricity consumption increased in all spheres in Iran, excepting industry sector during current year.

The growth in housing power consumption seems to have occurred due to increasing number of households connected to power grid in this year. The number increased by 712,000 to 26.451 million households.

U.S. Sanctions Slow Iran’s Electricity Generation And Trading

Image
By  Dalga Khatinoglu The peak electricity demand in Iran and its neighbor clients Afghanistan and Iraq happens in warm months, but during this period last year Islamic Republic’s exports plunged due to high demand at home. Its electricity imports from Armenia and especially Turkmenistan have been declining dramatically since September. This is possibly due to U.S. banking sanctions, which restrict Iran’s ability to pay its bills. During international sanctions prior to the nuclear deal (2011-2016), Iran was also unable to pay for Turkmen gas and electricity imports, running up $2bn in debts. Iran’s electricity trade during last and the previous fiscal years (GWh/month): ​ Power Generation Iran increased nominal power generation capacity by 2.3% last year; less than half of projected growth, but its actual electricity generation increased by only 1% to 312 TWh, a fifth of projected plan. The growth rate for actual power generation is far below nominal capacity, beca...

Iran in fighting with Caspian Sea pollution

Image
Iran, with its largest population on the Caspian Sea shore among other littoral countries, is keen to save the world's biggest inland body of water from pollution and has initiated a "Comprehensive plan to reduce pollution" plan. The Fars News Agency quoted the head of Department of Environment Mohammad-Javad Mohammadzadeh as saying that the plan targets preventing entry of pollutants, including household waste, especially in Gorgan and Mazandaran provinces, to the Caspian. Meanwhile, Abdolreza Karbasi, the deputy head of Environmental Protection of Iran alarmed about the ecological state of beaches, releasing warning to swimmers in the Caspian Sea. "The pollution at some parts of the sea has exceeded the authorized limit by 100 times," he said. Iranian coastal population is around 6 million people, including residents in the regions en route the rivers that flow to the Caspian, whose household waste waters enter the sea without passing through wa...

Iran Launches Uncompleted Gas Project Citing Suspiciously High Production

Iran’s Oil Ministry officially opened four new phases of the South Pars gas field March 17, citing production and investment figures that don’t add up. The nominal production capacity of the newly opened phases 13, 22, 23 and 24 is 113 million cubic meters per day (mcm/d), but currently they are producing about half of that. The processing units of these phases are also operating at half capacity most probably due to Iran’s technical limitations compounded by sanctions. Phase 13 is projected to produce 56 mcm of natural gas and 75,000 barrels of gas condensate (ultra-light oil) per day, when it becomes fully operational. The capacity of phases 22-24 are together equal to phase 13. The Oil Ministry said all phases will be operating at full capacity within one year. According to Oil Ministry’s statement, some $10 billion were invested in the mentioned four phases, but ministry officials put the figure at $11 billion during the inauguration ceremony, which President Hassan Rouhani ...
