Abu Dhabi sets new water management policy for cooling plants

ABU DHABI, January 18, 2023

Abu Dhabi's Department of Energy (DoE) has announced its new ‘Water Management in District Cooling Plants’ policy which is line with its responsibility to regulate and ensure the energy sector’s sustainability in Abu Dhabi, and in accordance with international best practices and standards.
The policy is aimed at regulating the mechanism of identifying potential sources of water that can be used by district cooling providers, such as recycled water, desalinated water, and sea water. 
This would allow for the usage of low-cost sources that have been deemed to be of acceptable quality after evaluating their capital and operational economic feasibility, said the statement from DoE.
It will also pave the way for evaluation of its compatibility with water discharge standards and environmental regulations to ensure their suitability for use in district cooling systems. 
Under the new policy, water sources can be used in district cooling systems if it proves to be the most feasible and cost-effective source. 
This requires prior planning in accordance with relevant water codes as well as ensuring availability of installations needed to meet the demand. 
The policy allows for a blend of water sources, provided the quality levels required for district cooling plant operations are met, it added. 
Engineer Ahmed Mohammed Al Rumaithi, the Undersecretary of the Department of Energy, said: "As part of our endeavour to implement Abu Dhabi’s Demand-Side Management and Energy Rationalization 2030 Strategy, we continue to enable initiatives that support energy efficiency and help protect consumers and the environment."
District cooling is one of the most critical areas that contribute significantly to achieving energy efficiency, providing 9% in overall energy savings against BAU baseline value. 
The ‘Water Management in District Cooling Plants’ policy helps overcome water sustainability challenges through cooperation among concerned entities to find appropriate alternatives that support district cooling operations in the emirate, he noted. 
Carlos Gascó Travesedo, the Acting Executive Director of Energy Policy at DoE, said: "District cooling is known for its low electricity consumption, which reduces pressure on the infrastructure required to generate electricity. It also mitigates fuel, operation, and maintenance costs of power stations, ensuring high savings in energy, cost reduction and environmental protection."
"At the same time, these systems consume substantial amounts of water to compensate for water losses resulting from evaporation, droplet drifts and blowdown in cooling towers. Hence it was necessary to allow district cooling companies and providers to explore feasible water sources that best suit their needs," noted Travesedo. 
He pointed out that district cooling capacity in Abu Dhabi was approximately 600,000 RT (Refrigerant Tons), which consumes 150,000 cu m of desalinated water per day (equivalent to 5% of the emirate’s total daily demand)
The adoption of recycled water and sea water will reduce pressure on desalinated water. However, it is necessary to ensure that recycled water is available wherever it is technically and commercially feasible, he added.-TradeArabia News Service
