*combined desalinated water and power production
OPWP is the single buyer of electricity and power from the licensed production
facilities. In 2005 OPWP purchased 10.8 TWh of electricity.
MIS contracted capacity increased to 2,865 MW in April 2006 with the commissioning
of a new Integrated Water and Power Production facility in Sohar. Sohar
has been operating at its full capacity of 585 MW from 2007.
OPWP will contract for a further 700 MW (IWPP) by 2009 from a plant located
at Barka which will provide 350 MW of early power in 2008.
Transmission
The Oman Electricity Transmission Company (OETC) is monopoly provider of
transmission services to the MIS. OETC own and operate the 220 kV and 132 kV
interconnected transmission system in the north of Oman and as system operator
is responsible for the central dispatch of generating and desalination facilities
connected to the MIS. OETC manages its system operator functions from a recently
commissioned load dispatch centre in Al Mawalleh. Information about the
