A glance at Iran's power sector in last fiscal year


Iran's power sector consumes about 400 million barrels of oil equivalent per year, sharing about one fourth of total primary energy usage in the country.
The latest weekly statistics, released on Energy Ministry's official website which covers statistics of last fiscal year, ended on March 21, indicate huge changes in the power sector, but not fundamentally.
According to the report, released on April 6, Iran has increased 2.871 GW power generation capacity including about 1.6-GW gas power plants, a 0.64-GW combined cycle power plant as well as a 0.52-GW hydroelectric power plant. However the actual power generation level increased by only 1.98 GW.

The statistics indicate that Iran increased gas supplement to power thermal power plants, which shares above 82.5 percent of the country's total power generation "capacity" during last fiscal year.
The country's total "power generation capacity" stood at 73.149 GW until March 20.
In regards to increasing the actual and nominal power generation capacity, it seems the efficiency of Iran's power plants hasn't become better during the couple of last years.
Hamid Chitchian, Iran's Energy Minister told Shana on March 4 that some 120 trillion rials ($4.8 billion based on official USD rate in Iran on March 4) has been allocated based on pay-back contracts during current fiscal year's budget law to increase the efficiency of thermal power plants (TPP).
He went on to say that the TPPs' efficiency is aimed to increase from its current 37.5 percent to 50 percent.
Iran has aimed to change all of gas thermal power plants into combined power plants (CCPP) which shares about 25.28 percent of the country's total power generation capacity. The efficiency of thermal power plants (excluding (CCPP) in Iran is about 31 percent while CCPPs' is 45 percent.
On the other hand, the country's electricity export decreased 14 percent to 9.965 billion KWh, while imports increased by 2 percent to 3.759 billion KWh during last fiscal year.
There is also a huge power loss during the transmission and distribution process, which reaches around 40 billion Kwh, or more than 14 percent of total actual electricity energy generation capacity. Iran hasn't been able to optimize the situation.

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

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, because

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
