2012-11-05 - ABB will deliver three mobile substations to Socièté Algérienne du Gestion du Réseau de Transport de L'Electricité (GRTE) to support rural electrification efforts in Southern and Northern regions of Algeria. These substations can be transported by truck and will be deployed to temporarily replace fixed installations, while maintenance and upgrades are carried out.

GRTE, the largest grid operator in Algeria, was established in 2004 as a joint-stock company by Sonelgaz, the state-owned utility responsible for electricity and gas distribution. Sonelgaz supplies more than six million households with electricity representing 98 percent coverage of the country. Algeria located in the northern part of Africa is the largest country on the continent and has over 225,308 kilometers of power lines, serving a 37 million population. It is expanding the size of its transmission network to reach isolated rural communities and support hydrocarbon developments in the Sahara Desert.
ABB’s compact and mobile substations, which can be installed and put into operation within hours will provide interim connections and temporary power supplies to help maintain grid reliability and respond quickly to outages. Mobile substations are particularly effective where the power grid is weak and prone to disruptions.
For GRTE, it is crucial to be able to move the equipment rapidly by trucks across all types of terrains including mountains to deserts. The mobile substations being supplied by ABB cover a wide range of 220/60-30 kilovolt (kV) ratings and each comprises ten equipment modules mounted on ten trailers, eight of which are containerized. The mobile units have the flexibility to operate as complete substations or as replacements for disabled feeders during failure or maintenance outages. They comprise an array of ABB products including high-voltage PASS (plug and switch system) hybrid switchgear, transformers and medium-voltage switchgear.
The units will be equipped with protection and control systems compliant to the IEC61850 open communications standard. When combined with state-of-the-art telecommunications equipment, this allows interoperability and enables remote monitoring and control from a central location. ABB will design, engineer and supply the substations within 15 months.
Mobile substations are grid code compliant and come as complete assemblies, ready to connect and easy to mobilize. ABB is the world’s leading provider of substation solutions and has previously supplied twenty mobile substations to Algeria.
