Saudi Electricity Co (SEC), the Gulf´s largest utility, contracted two companies for 2.5 billion riyals ($667 million) to build and operate the Green Duba power plant. Saleh Bin Hussein al-Awaji, Chairman, SEC, is working in full swing to take forward the major contract. Spanish solar firm Inteq Energia and the Saudi Services for Electro Mechanic Works (SSEM) have won the bids for the 605 MW plant, which will produce 43 MW of solar energy. Green Duba, planned to be built near Tabuk on the Red Sea coast, will be Saudi Arabia´s first fossil-fuel fired power plant to incorporate solar energy production to boost efficiency - known as an integrated solar combined cycle (ISCC) plant. According to al-Awaji, the solar portion of the plant will save the equivalent of 3 to 4 million barrels of fuel over the life of the project and reduce carbon emissions by between 40,000 and 50,000 tonne per year. Saudi Arabia, already one of the world´s largest carbon emitters per capita according to the World Bank, faces surging demand of 6-8 per cent per year for energy as its population increases rapidly and the economy grows; and with this massive contract, al-Awaji is all set to take environmental-friendly measures to another level.
