Iran combines a world-class solar resource — above 2,000 kWh/m² per year across the central plateau — with a chronic summer generation deficit. That pairing is the investment case: demand is not speculative.
The state renewables organisation SATBA contracts capacity through 20-year fixed-tariff power purchase agreements with an FX-indexation mechanism designed to protect hard-currency returns.
The tariff and its indexation
SATBA PPAs set a rial tariff with an adjustment formula referencing an FX rate and inflation indicators. The commercial question is not the headline tariff but which rate the indexation follows and how promptly payments settle.
Experienced sponsors negotiate payment security, curtailment treatment and force-majeure definitions rather than chasing the highest nominal tariff.
Grid and site selection
The binding constraint is not sunlight, it is evacuation capacity. Substation headroom, distance to the connection point and the seasonal load profile of the local network determine whether a site is bankable.
Wind is concentrated in a handful of corridors — Manjil in Gilan, Khaf in Khorasan, Sistan's 120-day wind — where capacity factors compete with mature European sites.
Equipment and local content
A domestic supply chain exists for mounting structures, cabling and balance of plant; modules, inverters and turbines are largely imported, making equipment logistics and payment channels central to project timing.
Storage is the emerging opportunity: the deficit is an evening-peak problem, and hybrid solar-plus-storage changes the value of a given site materially.
