GS Inima has commissioned a pioneering 6.5MWp solar plant alongside its Barka 5 desalination facility, representing a significant shift towards hybrid water-energy systems in Oman’s Gulf region amid rising calls for efficiency and sustainability.
GS Inima has successfully brought a 6.5MWp solar plant into permanent operation right beside its Barka 5 desalination facility in Oman. This move deepens the connection between renewable energy and water production, especially in a market where both sectors are under increasing pressure to become more efficient. Interestingly enough, the company claims this project is only the third of its kind in the Sultanate, meaning, it’s still quite a rare model in Oman’s water sector, highlighting how unusual such self-supply solar setups are in this region.
The photovoltaic installation is designed to supply around half of the electricity needed by the nearby reverse osmosis plant during daylight hours at full capacity. That’s pretty significant because, in this part of the world, desalination tends to be very energy-intensive. Plus, governments and developers are actively exploring ways to cut costs, bolster energy security, and reduce emissions, all while keeping water supplies stable.
According to GS Inima, the Barka 5 desalination plant already consumes about 2.7kWh of energy per cubic meter, an impressively competitive figure for high-volume reverse osmosis in that region. Now, by introducing solar power to that mix, the plant essentially becomes a hybrid facility. This blend is bound to attract interest from other utilities and developers across the Gulf, especially since hybrid systems seem to be gaining traction.
Developed by GS Inima and built together with Nafath Renewable Energy LLC, the project’s technical crew included OCA Global, acting as the owner’s engineer. Details shared by the company reveal that the plant uses 10,504 bifacial modules from Jinko Solar, each rated at 620Wp, mounted on fixed structures supplied by Mibet Energy. Power is fed through 18 Sungrow inverters rated at 320kW each, connected via an 11kV line.
GS Inima estimates that the solar plant will produce around 12,454MWh annually, with a performance ratio of 83.56%. Considering Oman’s tough coastal climate, that’s quite an achievement. Bifacial panels are especially relevant here, they can harvest reflected sunlight from the desert floor as well as direct rays, improving overall output over the plant’s operational lifetime.
Juan Jose Benayas, the CEO of GS Inima Barka 5, mentioned that the project underscores the company’s dedication to the energy transition and its ability to integrate water and power systems in a way that benefits both operations and the wider community. He also noted that this new PV setup reinforces Barka 5’s position as a pioneer in sustainable desalination in Oman.
Jacobo Stuyck, who leads GS Inima’s renewable energy initiatives, emphasized that integrating photovoltaics is a strategic focus for the company. He argued that this isn’t just about lowering operating costs, but also about proving that large-scale renewable hybrid systems can be commercially viable in water infrastructure projects.
The company also pointed out the project’s successful delivery record. They said Barka 5 went into commercial operation earlier than planned, despite pandemic-related disruptions. That early achievement helped establish the project as a reference in Oman, and now adding permanent solar self-supply enhances that reputation further in the realm of clean energy.
This initiative aligns well with Oman’s broader policy directions. Desalination remains central to water security across the Gulf, yet, it’s often criticized for its heavy reliance on fossil fuels. Projects like this solar-integrated approach could be a way to reduce that dependence, without needing major modifications to existing plant designs or delivery systems.
What’s particularly notable about the Barka 5 model is that it isn’t a pilot project or just a solar farm feeding the grid; it’s a dedicated on-site asset designed specifically to serve an industrial load. That simplifies economic assessments and allows for more immediate operational benefits, especially for developers who are considering long-term energy costs, resilience, and stability.
Furthermore, this project points to a broader shift in infrastructure planning throughout the region. As water producers are under increasing pressure to boost efficiency, cut emissions, and control costs, hybrid plants combining desalination with renewable energy sources are likely to become a lot more common. The Barka 5 project strongly suggests that this approach is no longer just experimental but has real, practical viability.
GS Inima positions this project as proof that the water-energy nexus can be managed more intelligently. Using renewable energy to support one of the most energy-intensive issues in public utilities makes sense, and if they’re onto something, Barka 5 could become a benchmark, not only in Oman but across other Gulf markets pondering similar investments.

Developed by GS Inima and built in collaboration with Nafath Renewable Energy LLC, this facility has an installed capacity of 6.5 MWp and is designed to supply up to 50% of the electricity required by the adjacent Barka 5 desalination facility during full daytime capacity. This integration of renewable energy underscores GS Inima’s commitment to the global energy transition and highlights their ability to implement innovative, sustainable solutions that optimise the water-energy nexus for the benefit of the community and the environment. The plant features 10,504 Jinko Solar bifacial modules (620 Wp) mounted on fixed structures from Mibet Energy, with power managed through 18 Sungrow inverters (320 kWac), resulting in an annual output of 12,454 MWh and a performance ratio of 83.56%. The integration of this renewable source enhances the existing efficiency of the Barka 5 IWP, which already stands as an industry benchmark with a remarkably low energy consumption of 2.7 kWh/m³, one of the most competitive rates in the region for high-capacity reverse osmosis. The entry into service of this PV plant is the latest in a series of achievements that have made the Barka 5 IWP a national reference in Oman. The desalination project itself set a high bar for the industry when it achieved its Commercial Operation Date (COD) ahead of the original contractual schedule, even while facing the global challenges of the COVID-19 pandemic. This development not only reinforces GS Inima’s commitment to sustainable operations but also sets a precedent for future desalination projects in the region.
