Iran's damned energy both in summer and winter


Iran, with 62.22 GW actual capacity faced temporary power outages in several provinces in recent days.
The peak demand of power in Iran has risen by 10 percent to 46.9 GW since the beginning of summer. 

Power consumption in Iran, in contrast with gas usage, soars in summer, but the recent increase level is so much more than what Iran's Energy Ministry expected.
There are several reasons for having problems with the huge electricity generation level needed for a country with a population of 77 million.
First of all, because of the low price of power - 450 rials (1.5 cents) for one kilowatt hours electricity- due to heaven subsidies has created a burden on government.
While the price of one kilowatt hours of electricity for comparison in the United States was over 12 cents in April.
The Iranian government has increased the price twice since 2010 based on implementation of Subsidy Reform plan, but cheap power still motivates people to consume more energy.
The other factor is the huge power loss during the transmission and distribution process, which reaches around 40 billion Kwh, or more than 14 percent of total actual power generation capacity.
The third reason is the power plant's low efficiency. The efficiency of the country's thermal power plants which shares 83.7 percent of total power generation is only 37 percent on average. The thermal efficiency of gas power plants is 30.6%, steam power plants is 36.8% and combined cycle power plants is about 44.5%.

The country used 36 billion cubic meters of gas, as well as 28 billion liters of diesel and fuel oil for power generation during last fiscal year, ended on March 2014.
The liquid fuels consumption in power plants indicates a 25 percent increase compared to the previous year, because of the gas shortage in winter.
The statistics of Iran's Energy Ministry and National Iranian Gas Company show that during summer when the housing sector consumes less gas, the power plants are fueled by about 180 million cubic meters of gas per day. During cold season, this figure drops to about 40 to 70 million cubic meters.
The deputy of National Iranian Gas Company Mohammad-Reza Gharavi told Shana on June 30 that fueling power plants with gas broke a new record on that day and reached 205 million cubic meters. He said that it's scheduled to supply 42 billion cubic meters of gas to power plants during the current fiscal year.
Soaring gas consumption last winter led to cutting the blue fuel supplying the industrial sectors. In addition to cutting the gas supply to power plants, which led to burning $30 billion of liquid fuels, the Iranian government had to decrease gas delivery to petrochemical plants from 35 million to 15 million cubic meters. This caused a drop in the petrochemical production by 7.5 million tons during the last fiscal year.
Iranian Deputy Oil Minister for International and Commercial Affairs Mansour Moazzami said in April that during last year the petrochemical units produced only 40 million tons of products due to the winter gas shortage and led to an $8-billion loss.
On the other hand, Iran cut gas supply to CNG production plants from 17 to 19 million cubic meters of gas to zero during winter, which caused gasoline consumption to soar to about 70 million liters per day in average during last fiscal year.

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 ...
