Amid ongoing nuclear negotiations between Iran and the United States, the head of Iran’s Atomic Energy Organization has claimed that the country’s electricity shortage will be resolved through the construction of new nuclear power plants. However, this promise appears more symbolic than practical, given the realities of Iran’s energy infrastructure and its long-standing neglect of renewable resources.
Nuclear Power: A Minimal Contributor
Currently, nuclear energy accounts for just 1% of Iran’s total electricity production. Bridging the country’s estimated 25,000-megawatt electricity deficit would require the construction of 25 nuclear power plants, each the size of the existing Bushehr facility.
Since becoming operational in 2011, the Bushehr plant has produced a cumulative 70 terawatt hours of electricity—worth less than $6 billion on regional energy markets. This figure is strikingly low, especially in light of Iran’s extensive uranium enrichment activities, which have been justified as necessary for power generation. Over the past 15 years, the sanctions imposed due to Iran’s nuclear program are estimated to have cost the country between $2 to $3 trillion in direct economic losses.
Despite repeated announcements of plans to generate 20,000 megawatts of nuclear electricity, no meaningful progress has been made. The head of Iran’s Atomic Energy Organization recently reiterated this target, while admitting it remains a “long-term” objective.
The Overlooked Potential of Renewables
Iran’s focus on nuclear power comes at the expense of more accessible and scalable alternatives. The country has vast untapped renewable energy potential—boasting 300 sunny days per year and extensive mountainous and coastal regions ideal for wind energy. Yet renewables currently make up only 1% of Iran’s electricity mix.
Globally, the contrast is stark. According to the International Energy Agency, 75% of all new power plants commissioned through 2024 are renewable-based. In contrast, nuclear energy contributed just 5% to global electricity generation growth last year.
A Nationwide Power Shortage
For the first time in its modern history, Iran is experiencing electricity and gas shortages across all seasons. This spring, nationwide rolling blackouts have been scheduled, with 90-minute daily power cuts imposed even in the capital. The situation is even more severe in the industrial sector, which faces two full days of outages per week alongside daily disruptions—significantly hampering productivity.
These blackouts are occurring during spring, when electricity demand typically hovers around 50,000 megawatts—35% lower than summer peaks. The fact that Iran cannot meet even this reduced demand is a red flag. Although the country’s nominal generation capacity stands at 94,000 megawatts, only about 62,000 megawatts are practically available due to aging infrastructure and underperforming hydropower facilities affected by prolonged droughts.
Fuel Shortages and Efficiency Failures
Over 90% of Iran’s electricity comes from thermal power plants, which run on natural gas, diesel, and mazut. However, the country now faces chronic fuel shortages year-round, crippling the operation of these facilities.
Making matters worse, many of these thermal plants operate at alarmingly low efficiency. According to a report by the Iranian Parliament’s Research Center, 15% of active thermal plants have an efficiency of less than 20%, and half operate below 35%.
Compounding the issue, Iran’s power grid suffers from severe transmission and distribution losses. Official data from the Ministry of Energy indicates that 13% of electricity is lost in transit—equivalent to 40% of the total electricity consumed by households, which use about 100 terawatt hours annually.
A Decade of Missed Targets
Since 2010, Iran has added an average of 800,000 new electricity subscribers per year, 70% of whom are in the residential sector. To meet this growing demand, electricity production should have increased by 7% annually. However, only half of the projected growth was achieved over the past decade, and in recent years, the success rate has fallen to just 30%.
While hydropower was temporarily ramped up to compensate for the shortfall—despite ongoing droughts—this strategy has had dire consequences. Some of the country’s key dams, which supply drinking water to major cities, are now nearly dry, holding just 7–10% of their capacity.
Conclusion: A Crisis in the Making
Iran’s electricity crisis is not merely the result of rising demand. It reflects years of mismanagement, misplaced priorities, and failure to invest in modern, sustainable energy sources. While officials continue to make lofty claims about nuclear power, the facts on the ground reveal a starkly different reality—one where the country teeters on the edge of a full-scale energy collapse, with little room left for improvisation.
