Abu Dhabi receives battery storage IPP bids

25 March 2025

 

Abu Dhabi-based utility and offtaker Emirates Water & Electricity Company (Ewec) has received proposals for a contract to develop and operate its first pair of battery energy storage system (bess) plants.

Called Bess 1, the 400MW project will closely follow 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 first plant will be in Al-Bihouth, about 45 kilometres (km) southwest of Abu Dhabi, and the second plant will be in Madinat Zayed, about 160km southwest of the city.

According to industry sources, the companies that submitted bids for the contract on 24 March include:

  • EDF Renewables (France)
  • Engie (France) / Saudi Electricity Company (SEC, Saudi Arabia) / Hajj Abdullah Alireza Company (Haaco, Saudi Arabia)
  • Jinko Power (China) / Alghanim International (Kuwait)

It is unclear if Saudi Arabia-headquartered Acwa Power submitted a bid for the contract.

The planned facility is expected to provide up to 800 megawatt-hours (MWh) of storage capacity.

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

According to Ewec, the bess project will provide additional flexibility to the system and ancillary services, such as frequency response and voltage regulation.

Ewec issued the request for proposals to prequalified companies in July last year and initially set 30 November 2024 as the last day to submit proposals. 

Ewec prequalified 11 managing partners that can bid either individually or as part of a consortium with other prequalified bidders.

It also prequalified 18 other companies that can bid as part of a consortium.

Global bess market

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.
