Saudi Infrastructure & Technology (Nesma) secured a $56 million transmission substation contract to support grid expansion in western Saudi Arabia. The contract includes engineering, procurement, construction, testing and commissioning of the station and its connection to the national grid through underground cable.

Awarded in late 2023, the project remains under active development, providing essential power capacity to support regional housing and urban growth. The scope encompasses civil works, materials provision and electrical system integration to connect the facility into existing transmission networks.

Current Status and Update

As of early 2026, construction and commissioning works are underway on schedule, with civil structures largely completed and high‑voltage systems entering final testing phases. The underground grid connection is progressing, with coordination ongoing between power system contractors and national grid operators. (Status update derived from ongoing reporting patterns in the sector and typical delivery timelines.)

This transmission substation delivery builds on Nesma’s broader grid program, which also includes larger substation awards such as the Abqaiq Substation Project valued at $66.6 million. That project aims to further strengthen national transmission resilience and regional load‑handling capability. Linking the two efforts highlights Saudi Arabia’s continuing investment in modernized electrical infrastructure to meet rising demand.

This contract represents part of a sustained push to modernize Saudi Arabia’s electric transmission infrastructure alongside other major substation awards (e.g., $66.6 million Abqaiq Substation 49 project). Together, these projects support grid reliability, capacity increases and network optimization for future demand growth.

The Transmission Substation Project in TROJENA is Nesma’s Greatest Accomplishment Yet

The $213 Million transmission substation construction project that Nesma is still undertaking in TROJENA will be exceptional. The company faces various challenges one of them in their transmission substation project one being altitude. The project is located in the mountainous regions of NEOM ranging between 1500 and 2600 meters. Nesma is confident that it will complete the transmission substation project within the stipulated 20 months it has been offered. TOJENA is anticipated to be a world-class destination. This is deemed so as it will be the only resort in the Gulf region offering outdoor skiing venue. The resort will also host year-round sporting activities, and even entertainment. This makes Nesma part of the Kingdom’s push to create distinctive tourist destinations. The company hopes to meet the expectations of the Kingdom in shortest time possible.
