Germany’s Siemens has won a SR133m ($35m) power transmission contract in Saudi Arabia from Saudi Electricity Company.

Siemens will install 115kV underground cables to a substation in Medina Second Industrial City. The company will complete the work in March 2012.

Earlier in January, Siemens won two other transmission contracts in the kingdom, worth a total of SR376m.

Both contracts are for 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.
