In the heart of Algeria’s El Oued Province,a 300MW photovoltaic power plant is turning one of the harshest environments on earth into a hub of clean energy. This landmark project plays a pivotal role in Algeria’s renewable energy strategy, aiming to diversify its energy mix and reduce reliance on fossil fuels.

The Sahara is a testing ground like no other: daily temperatures exceed 50°C, sharp temperature swings occur between day and night, and sandstorms sweep across the desert more than 200 days each year. Under such conditions, every component must meet the highest standards of performance, reliability, and safety.

In March 2024, China State Construction Engineering Corporation (CSCEC) signed the contract for the El Oued solar power project. Partnering with Longmax Technology, DELIXI Electric provided key low-voltage electrical solutions—most notably, the CDGNE-400 DC 1500V isolating switch—ensuring that the plant operates safely and efficiently despite the desert’s extremes.

Technology safeguarding solar power
At the heart of the system lies the DC combiner box, where the isolating switch acts as the “gatekeeper” of energy flow. DELIXI Electric’s solution was designed for high-voltage photovoltaic and energy storage systems, meeting the demanding requirements of utility-scale solar plants.

• Compact, world-first DC2000V design – developed specifically for modern solar applications, covering 1500V systems with precision.

• Clear and reliable isolation – a visible breakpoint design ensures safe operation and maintenance, eliminating risks of misoperation.

• Resilience under extreme conditions – built to perform reliably from –40°C to 80°C, resistant to dust, sand, and intense UV exposure.

• Sustained operational efficiency – reducing unplanned downtime and maximizing energy output.

The El Oued project is more than a power station; it is a milestone in Algeria’s path toward a cleaner, more secure energy future. The deployment of DELIXI Electric’s isolating switch demonstrates how advanced Chinese engineering is supporting international renewable energy ambitions and delivering practical results under some of the world’s harshest conditions.

This project highlights DELIXI Electric’s technological progress in high-end photovoltaic solutions and its commitment to international cooperation in building a greener future.
