Iran Breaks Ground on 5,000-MW Solar Plant Described by Officials as World’s Largest

Iran is set to begin construction on a 5,000-megawatt (MW) solar power plant in Kuhpayeh, Isfahan province, according to a West Asia News Agency report published Aug. 18.

Officials described the development as the largest solar facility anywhere in the world. The project is privately financed at $2.8 billion.

Ebrahim Karimi, who heads the energy desk at the Isfahan Governor’s Office, said ground would be broken on the site in the near future. The decision to build in the central Iranian desert follows years of studies that identified Iran’s desert plains as among the most promising areas in the world for solar generation ^[1].

Project Scope: Three Phases Across 6,000 Hectares

The installation will span roughly 6,000 hectares east of Isfahan, with construction divided into three phases of 2,000 MW, 2,000 MWs and 1,000 MWs, according to the report. Isfahan Gov. Mehdi Jamalinejad said the completed facility would be “the world’s largest solar power plant,” a title currently held by India’s Bhadla Solar Park.

Iranian officials said the Isfahan development would surpass leading sites in India and China in installed capacity and put output at nearly a tenth of Iran’s monthly electricity consumption. The expansion mirrors a broader global shift: BloombergNEF projects that solar will become the largest source of power by 2035 ^[2].

Energy Deficit: Peak Shortfall Measured at 13.6 GW

Iran’s grid has struggled to keep pace with demand, a problem compounded by chronic underinvestment, sanctions, extreme summer heat and war damage, according to officials. The Islamic Parliament Research Center calculated this year’s shortfall at peak summer consumption at 13.6 gigawatts (GW) the report stated.

The gap has shaped Iranian energy policy for years. An analysis published in Renewable and Sustainable Energy Reviews concluded that inconsistent policies and weak institutional support had slowed the development of renewable energy industries in Iran ^[3]. Officials argue that an additional 5 GW drawn from the sun could bring outages down by roughly half.

War Damage and Threats to Power Infrastructure

The U.S.-Israeli war on Iran has damaged gas fields, fuel-storage and petrochemical facilities, power plants, transmission lines and other electricity infrastructure, officials said. The conflict has also disrupted global energy supplies and effectively closed the Strait of Hormuz to regular commercial traffic, according to reports from NaturalNews.com ^[4]. The strait normally carries roughly one fifth of the world’s oil consumption and a similar share of global LNG trade, according to Watts Up With That ^[5].

In late May, engineers restored the South Pars industrial hub to pre-war output in under a month after a joint U.S.-Israeli attack in April, the second strike on the hub, according to officials. U.S. President Donald Trump warned in July that Iran’s power plants and bridges could be struck if Tehran did not return to talks with Washington, the report stated.

Renewable Expansion in Iran’s Energy mix

Recurring shortages have pushed Tehran to widen its renewable capacity in recent years, with solar taking a larger share of the energy mix, according to Iranian officials. The Isfahan plant would count among the heaviest renewable investments Iran has made and would place it among the leading builders of utility-scale solar worldwide, the report stated.

The shift toward large-scale solar follows years of declining costs for photovoltaic systems. Philip Warburg, in “Harness the Sun,” noted that Lazard’s life-cycle cost studies have tracked solar’s growing ability to compete with conventional fossil fuels and nuclear power ^[6].

The war has accelerated a shift in energy planning, officials said, exposing the vulnerability of Iran’s already strained grid. Some commentators have also pointed to local redundancy and decentralized generation as a way to reduce dependence on centralized power systems during conflict ^[7].
