The Dubai Electricity and Water Authority (DEWA) has undergone a remarkable journey from its modest origins to become a global leader in sustainability and innovation. Established with just 21 electricity connections and water supply to 49 residents, DEWA now serves as the exclusive provider of electricity and water in Dubai. Over the years, DEWA has not only met the essential needs of the city but has also driven its transition towards clean energy, technological advancement, and smart city solutions. DEWA's commitment to clean energy is evident through projects like the Mohammed bin Rashid Al Maktoum Solar Park, which is set to be one of the largest single-site solar parks globally and aims to achieve 100% clean energy for Dubai by 2050. The organization's Green Hydrogen project, producing hydrogen using solar power, is a pioneering initiative in the Middle East and North Africa region, supporting Dubai's move towards sustainable fuels and new energy technologies. In addition to renewable energy projects, DEWA is actively involved in infrastructure development and innovation. Initiatives such as the Hydroelectric Power Plant in Hatta and the EV Green Charger program for electric vehicles demonstrate the authority's commitment to driving progress in sustainable practices and technological integration. DEWA's success is not only measured in terms of sustainability but also in its financial achievements and partnerships. Through public-private collaborations, DEWA has attracted significant investments, listed on the Dubai Financial Market, and reported strong revenues. The organization's strategic approach, under the leadership of Saeed Mohammed Al Tayer, has positioned DEWA as a key player in Dubai's journey towards a sustainable and innovative future.
