UAE firm wins contract for battery storage project

10 October 2025

Etihad Water & Electricity (EtihadWE) and South Korea's Kepco have won the award to develop the UAE’s largest grid-side energy storage project to be awarded through open tender. 

Emirates Utilities Development Company (EUDC), a subsidiary of EtihadWE, will develop and operate the project in partnership with Kepco. As MEED understands, it is EUDC's first project since its establishment.

Chinese firm Dongfang International has been appointed as the EPC contractor.

Called Bess 1, the project closely follows the model of Abu Dhabi’s independent power project (IPP) programme, in which developers enter into a long-term energy storage agreement (ESA) with Ewec as the sole procurer.

The contract was signed at the Ministry of Energy in Abu Dhabi in the presence of senior officials from Dongfang Electric Corporation, EtihadWE and EUDC. 

In April, MEED reported that Ewec had received proposals for the facility, which is expected to provide a total storage capacity of close to 1GWh across two sites, Al-Bihouth and Madinat Zayed. It will also include supporting booster stations.

It is understood that the ESA will be for 15 years, commencing on the project’s commercial operation date, which falls in the third quarter of 2026. 

The overall capacity of deployed bess globally is expected to reach 127GW by 2027, up from an estimated cumulative deployment of 36.7GW at the end of 2023, according to a recent GlobalData report.

The report named Chinese companies BYD and CATL and South Korean companies LG Energy Solutions and Samsung SDI among the top battery technology providers globally.
