Local contractor wins Saudi substation deal

3 December 2025

Saudi Arabia-based Nesma Infrastructure & Technology has signed a contract with state-owned utility Saudi Electricity Company (SEC) to replace the Jubail Southeast 230/115/34.5kV substation.

The project includes overhead transmission line (OHTL) works and is valued at more than SR840m ($224m). It is scheduled to be delivered within 20 months.

The award forms part of SEC’s ongoing programme to upgrade ageing substations and reinforce network capacity in the Jubail industrial area.

In September, local contractor Al-Fanar Projects was appointed to replace the Jubail Southwest 230/115KV substation, one of several transmission assets in the region undergoing phased renewal.

As MEED recently reported, SEC has plans to invest SR220bn ($58.7bn) in power projects by 2030. This includes SR135bn ($36bn) and SR85bn ($22.7bn) for transmission and distribution, respectively.

According to the utility, its planned upgrades will cover 130 high-voltage substations, 135,000 MVA of capacity, 12,900 kilometres of overhead transmission lines and 1,100km of underground cables.
