As part of the turnkey project, the company will design, engineer, supply and commission the substations, including civil works.
ABB will supply power transformers, high- and medium-voltage air- and gas-insulated switchgear, instrument transformers, surge arresters as well as auxiliary and telecommunications systems for the project, which is expected to be completed by 2013.
The company will also install substation automation systems compliant with the global IEC 61850 communications standard and fitted with the latest protection and control equipment.
ABB Power Systems division head Peter Leupp said the new substations and the upgrades will significantly enhance distribution capacity and help meet growing industrial and residential demand for electricity in Algeria.
One of the new substations will power a solar panel factory being built close to the capital, Algiers.
