EWEC proposes developing 300 megawatts of Battery Energy Storage Systems to enhance overall network stability
EWEC also plans to continue investment in low-carbon intensive reverse osmosis water desalination technology to further decouple water and electricity production
EWEC (Emirates Water and Electricity Company), a leading company in the integrated coordination of planning, purchasing, system operations and supply of water and electricity across the UAE, today released its latest Statement of Future Capacity Requirements 2023-2029: Summary Report for Abu Dhabi’s future water and electricity production. The Statement recommends that, between 2023 and 2030, EWEC increase its total solar power generation capacity by 606 per cent to 7.3 gigawatts (GW), in addition to the development of 300 megawatts (MW) of Battery Energy Storage Systems (BESS). Furthermore, the Statement endorses continued investment in low-carbon intensive reverse osmosis (RO) water desalination technology to enable over 90 per cent of the total water demand to be met using RO by 2030.
Solar Power Capacity Increase
The Statement, published by EWEC and approved by the Abu Dhabi Department of Energy (DoE), outlines the future production capacity requirements for Abu Dhabi and beyond. The report forecasts the requirement for an additional 3GW (AC) of solar power capacity by 2029, in addition to the 1.5GW (AC) of solar power procured from Al Ajban Solar PV once it reaches commercial operations in 2026.
The report also recommends procuring a minimum of 300MW of battery capacity with a one-hour depth of storage by 2026, to provide operating reserves and other system services, improving system operability and enhancing overall network stability.
The implementation of these strategic renewable and clean energy projects will see the company’s average carbon dioxide intensity from electricity generation fall from 0.33 kilograms per kilowatt-hour (kg/kWh) in 2019, to an estimated 0.19kg/kWh by 2029.
Othman Al Ali, Chief Executive Officer of EWEC, said: “Our Statement of Future Capacity Requirements Summary Report demonstrates EWEC’s commitment to advancing the UAE’s energy transition while continuing to ensure a secure and reliable supply of water and electricity in the UAE. This report provides a powerful key reference that outlines Abu Dhabi and the UAE’s future needs. Our growing portfolio of renewable and clean energy projects is accelerating the decarbonisation of the country’s energy sector in line with the UAE Net Zero by 2050 strategic initiative whilst supporting the realisation of the Abu Dhabi Department of Energy’s Clean Energy Target 2035. The development of our world-leading strategic projects underpin the country’s journey towards a more sustainable future, positioning it as a role model for sustainable and efficient water and electricity production.”
Increasing Thermal Capacity
Thermal power projects using gas turbine technology are part of EWEC’s plans to support the transformation of the energy mix by serving as an effective bridge to a decarbonised energy sector that achieves the country’s energy transition objectives.
To meet reserve margin requirements, growing demand, and replace 7GW of contract-expiring thermal cogeneration plants, the Statement recommends securing a total of 9GW of thermal capacity from open- or combined-cycle gas turbines through asset extension, reconfiguration or new development.
Low-carbon Intensive RO Capacity
EWEC’s statement report also forecasts the need to proceed with the development of two low-carbon intensive RO desalination plants, Mirfa 2 Reverse Osmosis, which will have the capacity to produce 120MIGD of potable water, and the Shuweihat 4 Reverse Osmosis, with a production capacity of 70MIGD.
Additionally, the report also highlights the need to develop the 100MIGD Abu Dhabi Islands RO desalination project in 2027. This is primarily driven by RO’s substantial cost advantage over existing cogeneration assets. The unit cost of water from new RO is approximately 60 per cent lower than the current average system cost of water production. The report states that more RO is required to satisfy peak demand and reduce overall sector costs.
EWEC forecasts that over 90 per cent of its water production will be generated from RO water desalination plants by 2030. Additionally, it expects a reduction of water production emissions intensity from 11.5 kilograms per cubic metres (kg/m3) in 2019, to an estimated 1.4kg/m3 by 2029.
Bruce Smith, Strategy and Planning Executive Director at EWEC, said: “EWEC is leading Abu Dhabi’s transition to low-carbon-intensive water and electricity production. The report’s in-depth modelling analysis recognised significant system cost and carbon emissions reduction benefits from developing additional solar PV power and RO water desalination capacity, enabling the translation of these insights into actionable plans. EWEC is making tangible progress towards further diversifying the energy mix and increasing the share of renewable energy and low-carbon intensive RO to ensure a secure, sustainable, and least-cost supply of water and electricity across Abu Dhabi and beyond.”
