Saudi Electric Co has placed an order worth €65m with Siemens Energy for the supply of turnkey static reactive-power compensation systems. Siemens will supply three static Var compensators (SVCs) for different high-voltage levels for the stabilisation of the country's 60-Hertz power transmission network. The parallel compensation systems will be deployed at three sites in the Hiteen, Qassim and Afif substations and are scheduled to be ready for operation between mid-2011 and early 2012.
