The latest developments in Syria as well as the nuclear deal between Tehran and world powers featured high in the talks.
The deals were signed in Tehran by Syrian Electricity Minister Mohammed Zuhair Kharboutli and Sattar Mahmoudi, the acting head of Iran's energy ministry, the sources said.
During the more than six years of fighting, Syria's infrastructure has taken a tremendous hit.
The Aleppo contract was awarded to the Iranian firm Mabna and is valued at around 130 million Euros, according to a Kharboutli statement carried by SANA on Sunday.
"Iranian companies will have a role in rebuilding Syria".
Iranian companies will also rehabilitate a 90-megawatt power station in Dayr al-Zawr province, and another in the Homs province.

A contract was also signed for an Iranian company to supply power to the city of Aleppo, where the opposition-held eastern part of the city was retaken by Syrian President Bashar al-Assad's government in December of a year ago.
He said, 'We want the region to be stable and ask every country to behave proportionately to their territorial size, away from expansionism and greed'.
Iran has made inroads in other areas of Syria's economy, signing agreements to operate a new cell-phone system and gaining concessions on farming land, oil and gas, and phosphate mining.
Iran has already assured Syria to expand its cooperation to construct water and sewerage facilities in the Arab country.
More than 1,000 soldiers deployed by Iran's Islamic Revolutionary Guard Corps (IRGC) to Syria have died on the front lines of the multi-sided conflict in recent years.
"I felt that Mr. Putin like Iranian leaders is interested in the expansion of ties", he added. "Russian Federation has also shown good support for Iran with regard to the nuclear deal".
