Siemens said it has secured its biggest ever contract worth €790 million ($868 million) in Qatar from the state-owned utility Qatar General Water & Electricity Corporation (Kahramaa) for the expansion of the country’s power transmission network.

As part of the deal, Siemens will deliver 35 turnkey super and primary substations for Phase 13 of the Qatar Power Transmission System Expansion project.

This marks a significant milestone for Siemens, which has been involved in every stage of the project since Phase Four. The work will be completed in two years’ time.

Siemens will be responsible for the design, engineering, supply, installation, and commissioning of the substations for the 400-kV, 220-kV, 132-kV, 66-kV, and 11-kV voltage levels, including gas-insulated switchgear, transformers, and control and protection equipment.

On the big win, Siemens Energy Management Division CEO Ralf Christian said: “Since the upgrade programme started in 2005, Siemens has installed more than 120 substations and approximately 1,500 km of high-voltage cable.”

“With this new order intake, our completed and under-execution projects with Kahramaa have hit nearly €2.5 billion ($2.7 billion),” he added.

As part of this contract, an existing ‘super substation’ – one that allows multiple voltage settings – in Doha will be upgraded with new 400-kV/220-kV 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 providing temporary power feed to Rayyan Stadium, one of the venues for the upcoming 2022 Fifa World Cup.
