Dubai’s Hassyan IWP achieves world’s lowest tariff of 0.277 USD per cubic metre – United Arab Emirates After retendering the project, Dubai Electricity and Water Authority (DEWA) has achieved a new world’s breaking record for the lowest water levelised tariff of 0.277 USD per cubic metre for its 120 Million Gallons Per Day (MIGD) Hassyan Sea Water Reverse Osmosis (SWRO) Plant. The project is DEWA’s first Independent Water Producer (IWP) model project. DEWA has adopted the IWP procurement model for the Hassyan desalination plant following the success of the Independent Power Producer (IPP) model at the Mohammed bin Rashid Al Maktoum Solar Park projects.
