DEWA’s WETEX display details solar-plus-storage and water infrastructure plans
A 22 October exhibition update set out specifications for Dubai’s planned Solar Park Phase 7 and recapped hydrogen, pumped-storage and desalination projects without announcing a new contract.

Dubai Electricity and Water Authority (DEWA) used its two stands at the 20–22 October Water, Energy, Technology and Environment Exhibition (WETEX) to present projects across electricity generation, storage, water and digital operations. Its 22 October update describes an exhibition display, not a new procurement or investment decision. Among the items highlighted was Phase 7 of the Mohammed bin Rashid Al Maktoum Solar Park: DEWA says this planned phase comprises 2,000 megawatts of photovoltaic solar capacity and a battery system rated at 1,400 megawatts with six hours of storage, equivalent to 8,400 megawatt-hours. The project is to use the independent power producer model.
DEWA says Phase 7 is part of an expansion that would take the solar park above 8,000 MW, compared with the original 5,000 MW plan. A separate 2025 sustainability report gives the project’s expected commissioning range as 2027–2029 and records it as in progress at the time of that report. Those dates are background from the earlier document, not a revised schedule announced at WETEX. The exhibition release presents a model of the phase and does not identify the developer, construction contractor, battery supplier or a new project milestone. Its figures should therefore be read as the authority’s stated project design and plan, rather than installed capacity already operating.
The display also covered DEWA’s Green Hydrogen project at the solar park. DEWA describes it as producing about 20 kilograms of hydrogen per hour using solar energy, with a storage tank able to hold up to 12 hours of production. The utility’s project page says the installation was implemented with Expo 2020 Dubai and Siemens Energy and that stored hydrogen can be used for night-time power generation through a hydrogen gas motor of about 300 kilowatts. The WETEX announcement lists current uses in power generation and refuelling hydrogen vehicles and says the facility was designed to accommodate future energy, industrial and transport applications. It does not announce a production expansion or new customer.
On the water side, DEWA highlighted the Hassyan seawater reverse-osmosis plant. The exhibition release gives investment of AED 3.377 billion and a planned capacity of 180 million imperial gallons per day, describing it as the authority’s first project under the independent water producer model. DEWA’s project page confirms the same principal capacity and investment figures and says the plant uses reverse osmosis. The display also described Hatta pumped storage as a 250 MW generating project with up to 1,500 MWh of storage and an expected operating life of up to 80 years. These are project specifications, not output measurements published for the exhibition dates.
Taken together, the material links generation and flexibility with water supply: solar generation is paired with a large battery design; stored hydrogen is presented as a route to power and transport applications; and reverse osmosis and pumped hydro are part of the infrastructure portfolio DEWA chose to exhibit. The source does not quantify comparative system costs or establish that the showcased projects will operate as one integrated system. Its significance for EPC and infrastructure readers is the scale and technology mix disclosed for assets at different stages. Phase 7 remains planned, while the other pages supply project background and stated specifications. No contract value for Phase 7, construction schedule update or awardee was stated in the 22 October release.
