Production & Substations
Electricity production at the end of the second quarter of 2008 stood at approximately 4263 Megawatts (MW), and is expected to double by 2011 to more than 8707 MW.
This clearly shows continuous and tremendous growth in Qatar's electricity sector. Within eight years (2000 – 2008), the number of high voltage primary substations increased from 87 substations to 139 substations (2nd quarter of 2008), and is expected to reach 269 substations by 2011.
The number of distribution substations increased in association with the high voltage transmission primary substation, and exceeded 8000 distribution substations (2nd quarter 2008); it is planned to reach 10.000 distribution substations by the year 2011, in order to cope with the substantial increase in economic activity in Qatar at all levels.
Cables & OHL
This large increase in the number of primary substations was accompanied by the massive expansion in the cables and overhead lines (OHL) network in the 11 kV, 66 kV, 132 kV and 220 kV voltage levels. Up to 2008, the length of double circuit cable line laid stands at approximately 1064 kilometers (km) the OHL stands at 1820 km. The cumulative investment (2000 – 2008) calculated in the electricity sector stands at US$9.64 billion.
NCC & DCC
The main electricity transmission network is monitored and managed by KAHRAMAA's National Control Center (NCC), and the distribution network is monitored and managed by the distribution control centre (DCC). These centers are equipped with state-of- the art technology and operated by qualified and experienced staff.
Electricity Expansion Projects
The highly sophisticated power equipment installed at various substations, is operated and maintained by the qualified and experienced engineers and staff of KAHRAMAA, making the electricity transmission and distribution system highly reliable and dependable.
The development and expansion projects of Qatar Electricity Transmission Networks attract the attention of major international companies, as KAHRAMAA\s projects are deemed among the largest package projects in the world. The last awarded project of electricity network expansion – Phase VIII, for example, included contracts worth more than US$ 3.5 billion. There is the impending project of a Phase IX Network.
Future expansion is expected to be worth more than that of Phase VIII. KAHRAMAA's Department of Technical Affairs is responsible for all contract matters and managing these projects to finish on time.
GCC Interconnection Grid
KAHRAMAA is also ready to join the GCC Electricity Interconnection Grid. Several 400 kV transmission substations, overhead lines, cable circuits and NCC development projects are under construction to ensure that they are completed in time to meet the GCC electricity interconnection requirements.
Demand for electric power in Qatar has increased manifold over the past fifty years; for example, demand registered, as system maximum load on 10th of September 1988 was 941 MW while it reached 3550 MW on 10th September 2007. The latest demand registered as on 30th of August 2008 is 3990 MW.
Average electricity consumption per capita had increased from 12.963 kilowatt hours (kWh) in 1997 to 17.774 – kWh in 2007 less transmission and distribution losses.
Electricity customers' number increased as well within the last ten years from 132.429 in 1998 to 191.476 customers in 2007.
