HDEC

On August 22, 2025, at 17:20 local time in Medina, Saudi Arabia, the Saudi REPDO4-AHK photovoltaic project successfully achieved full-capacity grid-connected power generation at 1,230 MWp, laying a solid foundation for its official entry into commercial operation. This milestone marks the successful completion of all construction and commissioning objectives, adding another landmark achievement to HDEC’s portfolio of large-scale overseas clean energy EPC projects.

Following the successful one-time backfeed of six circuits at the 110 kV booster station on July 28, this milestone represents yet another critical node in the project’s execution. As the first independently contracted and implemented gigawatt-level overseas PV project undertaken by HDEC, it took over 15 months from commencement to completion. Despite multiple challenges, including extreme heat, frequent sandstorms, and tight operational windows, the project seamlessly transitioned from “station construction” to “stable power generation” with high quality. This fully demonstrates HDEC’s capabilities in systematic integration, localized operation and maintenance, and project execution in complex international environments.

Team Profile: 3,500 Personnel Working Around the Clock for "Faultless Execution"

Since August 2024, the project department has fully implemented a “two-shift system” to ensure uninterrupted continuous operations. During peak periods, the number of on-site management and construction personnel exceeded 3,500, spanning dozens of specialties including civil engineering, electrical engineering, communications, security, and commissioning.  They established a highly efficient collaborative system across time zones, languages, and cultures. Facing challenges such as limited local supply chain capacity and fluctuations in international logistics volatility, the project department adhered to a goal-oriented approach, dynamically optimizing procurement scheduling and node linkages. During the pre-grid sprint phase, specialized teams conducted multiple rounds of cross-inspections and preemptive tests daily to ensure every step was “traceable, verifiable, and closable”.

Projects Highlights: From Execution and Delivery to Local Empowerment

As a key practice of the “Going Global” strategy of HDEC, the REPDO4-AHK project not only achieved high-quality delivery but also advanced local capacity building. It established a training and on-site support system covering construction, commissioning, safety, and technology, driving local employment and team development. To date, the project has achieved over 6 million safe work hours without major personal injury incidents, receiving an “Excellent ESG Performance” evaluation from the client Masdar and was honored with the “International Safety Award” from the British Safety Council.

Looking Ahead: Demonstrating Effictiveness Through Operation, Enhancing Efficiency Through Strability

The full operation of the project provides a mature model for HDEC to deepen its presence in the Middle East and markets along the “Belt and Road” initiative. In the next stage, the project department will focus on operational support, improving monitoring and defect resolution mechanisms, and optimizing specialized maintenance plans for high-temperature and sandstorm seasons. These efforts will continuously enhance equipment availability and equivalent utilization hours, ensuring the long-term, safe, stable, and efficient operation of the power plant. Taking this project as a new start, the team will continue building internationally influential clean energy demonstration projects, contributing “HDEC Wisdom” to global energy transition and sustainable development.
