Turkey and Iran agreed in principle to expand their electricity trade and build dams and power stations, said Turkish Energy Minister Hilmi Guler.
"We believe we can sign a memorandum of understanding later Thursday," Guler said after talks with his Iranian counterpart Parviz Fattah, the Anatolia news agency reported.
The projects include upgrading existing power lines through which Iran sells Turkey electricity and building additional lines, the two ministers said.
"We agreed to multiply by 2.5 the capacity of the two existing power lines between our countries and to build two more lines if need be," Fattah said.
Guler said that they also discussed proposals to build dams and natural gas- or oil-fueled power stations.
Fattah invited Turkish companies to look at the possibility of building dams and power plants in Iran. 
"Iran is completely ready for such investment and cooperation," he said.
Trade volume between Turkey and Iran was $6.7 billion in 2006, with the bulk of Iranian sales in the form of oil and natural gas carried via a pipeline linking the two neighbors.
Turkey and Iran have notably improved ties over the past several years after an icy period marked by Turkish accusations that Iran was sheltering Turkish Kurd separatists and aiding Islamist extremists.
