Germany’s Siemens has won two transmission contracts in Saudi Arabia, worth a total of SR376m ($100m).

Both contracts cover the installation of dynamic reactive power compensation systems in the Central Province. These systems improve the efficiency of an electricity grid and increase the amount of power that can be transferred across the network by reducing random voltage variations.

Siemens is due to complete work on the first contract, worth SR198m, in November 2011. The company will deliver work under the second, SR178m contract by August 2012.

Saudi Electricity Company is the client for both contracts.

On 4 January, Siemens won a separate SR326m contract to build a substation in the kingdom. Under the engineering, procurement and construction contract, Siemens will build the 380/115/34.5kV substation at Yanbu Industrial City. The Royal Commission for Jubail & Yanbu is the client.
