Seville-based Instalaciones Inabensa will join forces with Cobra Instalaciones & Servicios to undertake the two packages. The main element covers the construction of four 400/220-kV gas-insulated switchgear (GIS) substations at a total cost of Eur 215.6 million ($247 million).

In addition, Inabensa and Cobra will install a 400-kV high-voltage transmission line stretching 500 kilometres between El-Raweis and Wadi al-Rabia. Within the protective casing of the line, the Spanish groups will also install a fibre-optic cable, connecting it to telecoms equipment along the route. Total costs for this stage are put at Eur 85.5 million ($98 million).
