Kahramaa awards $863m substation contract to Siemens
The award is Siemens largest contract to-date in Qatar for the expansion of the country’s power transmission network
Siemens has been awarded a substation contract by state-owned utility company, Qatar General Water & Electricity Corporation (Kahramaa).
The award is Siemens largest contract to-date in Qatar for the expansion of the country’s power transmission network.
As part of the deal, valued at $863m (QAR3.1bn), Siemens will deliver 35 turnkey super and primary substations for Phase 13 of the Qatar Power Transmission System Expansion project.
Siemens has maintained involvement in every stage of the project since Phase 4.
Completion is scheduled in two years’ time. Siemens will be responsible for the design, engineering, supply, installation, and commissioning of the substations for the 400-kilovolt (kV), 220-kV, 132-kV, 66-kV, and 11-kV voltage levels, including gas-insulated switchgear, transformers, and control and protection equipment.
Ralf Christian, chief executive officer of Siemens energy management division, said: “Since the upgrade programme started in 2005, Siemens has installed more than 120 substations and approximately 1,500km of high-voltage cable.
“With this new order intake, our completed and under execution projects with Kahramaa total nearly $2.73bn (QAR9.94bn).”
As part of this contract, an existing ‘super substation’ – one that allows multiple voltage settings – in Doha will be upgraded with new 400kV/220kV gas-insulated switchgear and associated equipment, before connecting to the grid.
Another substation will be used to meet rising demand for electricity in Al Jahhaniya and surrounding area, including temporary power feed to Rayyan Stadium, one of the venues for the upcoming world soccer championship.
Substations will also feed power to steel, oil and gas and petrochemical facilities in Mesaieed industrial area, as well as Al Sadd area in Doha.
Overall, the substations are required to supply power for ongoing infrastructure development projects, schools, hospitals, industries and residential complexes in and around Doha, Qatar’s capital city.
In addition to Phase XIII, Siemens also received a second order from Kahramaa to supply and install more than 2,170 medium-voltage switchgear boards.
8DJH Siemens switchgear will be used as ring main units (RMU) in the 11 kV distribution network.
RMUs protect, for example, transformers connected to the grid against overloads and short-circuits, ensuring a reliable power supply.
The switchgear will be manufactured in Frankfurt, with the first units expected to go into operation by end-2017. The order is valued at roughly $29.5m.
