Dubai Electricity and Water Authority (DEWA) was formed on 1 January, 1992, by a decree issued by the late Sheikh Maktoum bin Rashid Al Maktoum to merge Dubai Electricity Company and Dubai Water Department, which had been operating independently before then. Both organisations were established by the late Sheikh Rashid bin Saeed Al Maktoum in 1959. Dubai Government fully supported the Electricity Company and the Water Department to provide Dubai’s citizens and residents with a continuous and reliable supply of electricity and water. Since then, DEWA has made considerable achievements, to be ranked as one of the best utilities in the world. DEWA provides services today to more than 760,000 customers with a satisfaction rate that reached more than 94% in 2015

DEWA is managing and operating the Mohammed bin Rashid Al Maktoum Solar Park, which is the largest single-site solar project in the world. It will produce 1,000MW by 2020 and 5,000MW by 2030, with total investment of AED 50 billion.

To emphasise its commitment to sustainability, which is one of the main pillars of World Expo 2020 in Dubai, DEWA is working in line with the vision of HH Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, to host the best World Expo that the world has ever seen in Dubai. DEWA will contribute to achieving this by building world-class energy infrastructure that meets Dubai’s development demands. DEWA has launched a wide variety of initiatives in this regard, allocating more than AED 2.6 billion to boost water, electricity and renewable energy projects according to the highest international standards. This supports Dubai Expo’s theme of ‘Connecting Minds, Creating the Future’ and its three sub themes of sustainability, mobility and opportunity.​
