Flagship project
Supporting Delivery of Saudi Arabia's 400 MW Dumat Al Jandal Wind Farm
Dumat Al Jandal's 400 MW wind project required rapid Owner's Engineering support across electrical, civil and equipment interfaces during delivery.
The challenge
Rapid mobilisation was needed for a major wind project already moving through design and construction. Critical interfaces included the 132 kV overhead line, cable performance, roads, substations, factory tests and turbine blades, any of which could affect schedule or long-term reliability.
Our goal
The assignment was intended to reinforce the owner's technical oversight of the 400 MW Dumat Al Jandal wind farm. Focused engineering reviews and specialist support would help the project resolve priority risks quickly while maintaining quality across the plant and its connection infrastructure.
Our approach
Owner's Engineering resources were mobilised around the workstreams requiring immediate review. The available scope included 132 kV overhead-line design, cable sizing and loss calculations, access-road engineering, substation matters, factory acceptance testing and specialist blade input. Technical advice could be targeted flexibly as project priorities evolved.
Impact in numbers
Timely independent review can identify design weaknesses before they become expensive site changes or operational constraints. Better cable, line, road and equipment decisions protect both delivery and future maintenance. At Dumat Al Jandal, focused Owner's Engineering could therefore strengthen confidence in a strategically important renewable-energy project of exceptional national scale.
Key highlights
- The 400 MW scale made efficient issue resolution especially important.
- The support model was designed for quick mobilisation and could draw on different disciplines without creating a separate full-project structure.
- Electrical, civil and turbine-equipment questions were considered as interconnected elements of the same operating wind asset.
Success story
Large wind developments rarely face one single technical problem at a time. A transmission-line decision may affect the grid schedule, a cable calculation may influence losses and cost, and road geometry can determine whether turbine components reach site safely. The Dumat Al Jandal assignment was structured to bring the right specialist attention to those priority interfaces quickly. Reviews of 132 kV lines, substations and cables could sit alongside road, factory-test and blade expertise. This flexible support gives the owner an informed second view when decisions are time-sensitive. The positive result is risk resolved before it becomes embedded in construction, helping a 400 MW project move towards operation with stronger technical assurance across the infrastructure that supports its turbines.
