The agreement was signed in the Norwegian ambassador's house and according to Norway's ambassador to Tehran, Lars Nordrum, has a value of just under $3 billion.
The paper quotes Gaute Kolnes Steinkopf, adviser to Saga Energy and one of those who arranged for the deal, saying, "Iran has said that they want to increase the share of renewable energy, and we have long worked for Norwegian companies to go in and do the job."
According to the agreement, a number of solar parks will be established around Iran, which together will produce two GWs. It is enough to power about three million households.
The deal was signed less than a month after UK renewables investor Quercus signed a deal worth over half a billion euros to build and operate another 600 MW solar farm in Iran.
To date, Iran has 63 MW of installed solar capacity, chiefly in the cities of Yazd, Kerman, Isfahan and Hamadan. The government is taking steps to bolster the renewable energy market, including an objective to install 5 GW of new renewable energy capacity by 2020, accounting for 5% of generation.
