Grid components supplier ABB said it booked a $150-million order in Saudi Arabia to expand five substations that will help accommodate expanded electricity generation capacity.

ABB said the order from the Saudi Electricity Company, which includes gas-insulated switchgear and automation equipment, was booked in the second quarter of 2015.

With oil and gas reserves driving economic growth, Saudi Arabia is boosting its power generation capacity by more than 50 per cent by 2020 to about 91 gigawatts (GW), from less than 60 GW now.
