Unit International, a Turkish-owned but Brussels-based energy firm held by businessman Unal Aysal has been contracted to build seven power plants in Iran, with a total installed capacity of 6GW.
The contracts were signed in Tehran on 1 June, with Iran’s Thermal Power Plants Holding Company, which is acting on behalf of the country’s energy ministry.
Once completed, the plants are expected to increase Iran’s current energy output by as much as 10%.
According to Mohsen Tarztalab, MD of Thermal Plants, more than a thousand hours of negotiations took place, over a period of a year, before an agreement covering all the plants was reached.
Construction on the power stations is set to begin in the first quarter of 2017, with Unit International providing the capital for the build.
Once completed, the agreement will see Unit International operating the power stations for 20 years.
Mr Aysal said the deal constituted the largest investment made in Iran since UN sanctions were lifted and “one of the largest made in a single package in the world”.
Unit International had previously begun building gas power stations in Iran, including the 2.2GW Rudeshur project in Tehran, before work was interrupted by the 2006 UN sanctions.
