Alstom Grid’s Tampere unit will supply equipment to power transmission project in Saudi Arabia


Alstom Grid has been awarded a turnkey contract by Saudi Electricity Company (SEC) to supply Flexible AC Transmission Systems to the Quwayyah substation in Saudi Arabia. Alstom’s Static VAr Compensator (SVC), to be supplied by Alstom Grid’s Tampere unit, will improve power quality across the utility’s AC network. The SVC is part of a project with a total value of approximately €30 million for Alstom Grid.

Alstom Grid’s Tampere based Power Electronics unit will be engineering, manufacturing, testing and delivering the Static VAr Compensator (-50/+170 MVAr 132 kV) with the associated capacitors and air-core reactors for the Quwayyah substation, located approximately 200 km west of Riyadh. The SVC is due to be energised in January 2015.

The civil, construction and installation works, supply logistics (transformers, 132 kV gas-insulated substation and equipment) and local project management will be managed by Alstom Grid’s local unit in Riyadh.

While improving operating costs, SVCs also dynamically supply reactive power (capacitive or inductive) to stabilise the voltage and dampen transmission system instabilities. This helps to mitigate the effects of both system faults and fluctuating loads, balancing the energy flow as required by the transmission network.

Jouni Mälkönen, Managing Director for Power Electronics Unit at ALSTOM Grid Oy said: “The order for this turnkey project is important proof of our competitiveness in the Middle East transmission market and shows the trust that our customers have in Alstom’s capability to deliver complex power transmission projects.”

Saudi Arabia’s electricity demand is currently rising at 8% per year, with extensive plans for industrial development by 2022, and six new major cities being built across the Kingdom. This electricity demand is expected to reach 70 GW by 2020, against a current national generation capacity of 40 GW today. Alstom Grid, as global leader in grid development, is supporting the Kingdom of Saudi Arabia’s energy booming.
