The estimated $400 million project calls for the construction of:
220/66/11-kV substations at Abu Hamour North and at the hospital;
132/66/11-kV substations at Maither Central and Nassir bin Abdullah;
A 66/11-kV substation at Doha industrial C.
It also involves the installation of: 220-kV cables between the Doha Super substation and the Abu Hamour North substation, and between the Abu Hamour North substation and the hospital substation; 132-kV cables between the Gharafa substation and the Nassir bin Abdullah substation, and between the Al-Wajba substation and the Maither Central substation; and 66-kV cables between the Saliya South substation and the Doha industrial C substation.
Other works involve modifications to parts of the existing 66-kV network and national control centre, the construction of a new distribution control centre for the 11-kV network, and the installation of a new supervisory control and data acquisition (SCADA) system for the water network.
The first package covering the 220-kV substations and the SCADA system is expected to go to tender in the second quarter of 2003. Implementation will take two years.
