KHOBAR, Saudi Arabia, Jan 4 (Reuters) - Saudi Saline Water Conversion Corp (SWCC) expects its water and electricity complex in Ras Al Khair to reach full capacity by the end of March, it said on Monday.

The power plant has a capacity of 2,400 MW and the project will be able to remove salt from over 1 million cubic metres of water a day.

Saudi Arabian Mining Co. has rights over 1,350 MW of the capacity; the other 1,050 MW has been allocated to Saudi Electricity Co.

SWCC has supplied 760 cubic metres of desalinated water over the past 22 days, Abdulrahman bin Mohammed al-Ibrahim, head of SWCC, said in a statement.

In 2014, SWCC began a gradual start up of its power generating units.

Power production at Ras Al Khair, on the Gulf coast was originally expected to start in late 2012 but was delayed by construction issues, slowing plans to ramp up output at Ma'aden new aluminium smelter, which it shares with U.S.-based Alcoa.
