WETEX puts Dubai’s solar, storage and water programmes in a single supplier-facing frame

Direct answer

WETEX opened with 3,000 exhibitors from 60 countries. DEWA reported 4,660 MW operating at its solar park and presented Phase 7 as 2,000 MW of PV with a 1,400 MW six-hour battery system, alongside major water and pumped-storage assets.

Limits and what this does not prove: Before commitment, verify: Current DEWA procurement notices, prequalification requirements and package status for each named programme; Award, construction and commissioning evidence separating planned capacity from operating assets; Technical specifications, local-delivery requirements and IPP/IWP risk allocation relevant to a supplier’s exact offer.

WETEX places multiple Dubai utility programmes in one current frame, but suppliers still need to separate operating assets, planned capacity, procurement stages and exhibition visibility.

What changed

WETEX opened with 3,000 exhibitors from 60 countries. DEWA reported 4,660 MW operating at its solar park and presented Phase 7 as 2,000 MW of PV with a 1,400 MW six-hour battery system, alongside major water and pumped-storage assets.

The official WAM account records 3,000 exhibitors from 60 countries, 13 international pavilions and 60 sponsors at the 28th WETEX. It also records DEWA’s current project statements: 4,660 MW operating at the Mohammed bin Rashid Al Maktoum Solar Park; a seventh phase designed for 2,000 MW of photovoltaic capacity and a 1,400 MW battery system with six hours of storage, equal to 8,400 MWh; and an independent-power-producer model for that phase.

The same source identifies Hassyan reverse osmosis at AED 3.377 billion and a stated 180 million imperial gallons per day during 2026, plus Hatta pumped storage at 250 MW and 1,500 MWh. Those figures help suppliers identify technical themes—solar, batteries, desalination, storage, grids and digital operations—but a model on an exhibition stand is not a live tender, prequalification or award. Operating, planned and procurement-stage assets must remain separate in every sales pipeline.

A credible response starts with the exact product or service and the named DEWA programme. The company should then locate the current procurement notice, package owner, technical standard, qualification gate, local-delivery requirement and commercial model. WETEX can support meetings and discovery; it does not, by itself, establish an addressable contract or permission to bid.

Business impact

  • WETEX opened with 3,000 exhibitors from 60 countries, 13 international pavilions and 60 sponsors across energy, water, environmental and digital technologies.
  • DEWA reported 4,660 MW operating at the Mohammed bin Rashid Al Maktoum Solar Park and described Phase 7 as 2,000 MW of PV plus a 1,400 MW battery system designed for six hours, or 8,400 MWh.
  • The same official report identifies Hassyan reverse-osmosis investment of AED 3.377 billion, Hatta pumped storage at 250 MW/1,500 MWh and other assets, but it does not publish an open tender or supplier qualification route.

Watch next

  • Current DEWA procurement notices, prequalification requirements and package status for each named programme
  • Award, construction and commissioning evidence separating planned capacity from operating assets
  • Technical specifications, local-delivery requirements and IPP/IWP risk allocation relevant to a supplier’s exact offer

What the evidence supports

  • WETEX reports 3,000 exhibitors from 60 countries; participation is ecosystem evidence, not procurement access.
  • The solar park’s 4,660 MW operating figure must not be merged with the 2,000 MW planned seventh phase.
  • The seventh-phase battery design is 1,400 MW of power for six hours, equivalent to 8,400 MWh of energy.
  • Hassyan and Hatta figures are project context; current package, award and supplier status require separate official evidence.

Horizon interpretation

Why it matters commercially

The figures identify scale and technical direction, not an open order book. Suppliers must link their offer to a current DEWA notice, package, qualification route and project stage before assigning revenue or allocating bid resources.

Questions before acting

  1. 1Which named programme and technical package can the company serve, and what current document proves that package is accessible?
  2. 2Does the offer meet DEWA qualification, bankability, warranty, local-support and project-delivery expectations?
  3. 3Is WETEX being used for a defined target-account plan or only as broad market visibility?

Source and editorial position

Project and exhibition figures are attributed to WAM and DEWA on 21 October 2026. Horizon separates operating, planned, exhibition and procurement evidence and makes no claim that a tender or supplier route is open.
