Efficient use of energy, water a must: Dewa
BY A STAFF REPORTER November 17, 2012

Dubai: Saeed Mohammed Al Tayer, MD and CEO of Dubai Electricity and Water Authority (Dewa), has stressed the fact that it is almost five years since the launch of Dubai’s Sustainability drive, marked by His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of  Dubai’s  declaration of the Green Building Initiative.

This was said during the International Conference of Energy, Utilities and Mining organised in Atlantis Hotel for the first time in Dubai, by Price Waterhouse Coopers, the international leading company in the field of international professional services under the theme “New Frontiers: Strategies And Regions That Are Reshaping The Future Of Energy, Utilities and Mining Sectors” and in the presence of more than 500 delegates from Price Waterhouse Coopers global offices.

This initiative strengthens the fact that efficient use of resources in general, and energy and water in particular, has become a must rather than a choice. Through new methods of design, construction and operation of buildings, electricity and water consumption can be reduced to a large extent.

“Dubai Electricity and Water Authority is the single vertically integrated electricity and water utility in Dubai. We own and operate the power generation and associated desalinated water production facilities, electricity and water transmission and distribution networks. We are also responsible for the supply and sales of electricity and water to consumers,” said Al Tayer.

Currently the combined power generation and desalinated water production in Dubai is most efficiently produced using natural gas and LNG as the primary fuel (99 per cent) and supplemented by liquid fuel -  Diesel Oil as a secondary fuel (1 per cent). Desalinated water is the main source of water supply in Dubai. For the year 2011, the water supply to the Dubai Emirate consisted of 97.6 per cent desalinated water, and the balance 2.4 per cent from groundwater.

“To reduce reliance on natural gas, and the impact on the environment, whilst improving security of supply by diversifying the fuel supply mix, an integrated energy strategy for Dubai has been formulated (DIES 2030). The proposed future power generation mix will consist of a mix of gas, solar, clean coal and nuclear energy sources as follows: by 2030: Gas - 71 per cent; Solar - 5 per cent; Nuclear - 12 per cent; Clean Coal - 12 per cent. The strategy also aims at reducing energy demand by 30 per cent by 2030. 

Al Tayer also said that water is of no less importance than power in Dubai. The production of desalinated water is an energy consuming process, requiring considerable amount of power, while water demand is expected to continue to increase due to the economic and population growths.

 To meet the continuously growing water demand, effective water management practices are in place, such as continuous optimisation at the desalination plants and water leakage management.

Whilst we are proud of our achievements so far, we are also fully aware that some of yesterdays or even today’s conventional solutions may no longer be appropriate going forward. In common with many in the MENA region and much of the world, we have to further enhance the energy efficiency. A substantial amount of energy is used globally, and at the same time a considerable amount is wasted too.
