Modernisation Of DEWA Contributes To Reduce Carbon Emissions | |
| Sumita Pawar |
Dubai Electricity and Water Authority's (DEWA) upgrade of three gas turbines at the E-station Phase -1 of its Jebel Ali Power Plant and Water Desalination Complex has contributed to reducing carbon dioxide emissions by around 65,930 metric tonnes per year.
And NOx emissions by 77.3% for these turbines, which is equivalent to that of the latest state-of-the-art gas turbines on the market, said the report.

"We support the directives of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, to make Dubai a role model for the efficiency, reliability, and availability of water and electricity. "We also support the Dubai Clean Energy Strategy 2050 and the Dubai Net Zero Carbon Emissions Strategy 2050 to provide 100% of Dubai’s total power production capacity from clean energy sources by 2050."
"We aim to deliver a state-of-the-art infrastructure according to the highest international standards." "This contributes to achieving the sustainable development goals and supports the growth of the sustainable green economy in the UAE," said HE Saeed Mohammed Al Tayer, MD and CEO of DEWA.
"DEWA’s application of the latest Fourth Industrial Revolution technologies and disruptive technologies, including artificial intelligence, unmanned aerial vehicles, and other innovative technologies, the redesign of operations, engineering, and solar power generation technologies, as well as clean water desalination, improved the efficiency of power generation, which has led to significant financial savings," added Al Tayer.
Nasser Lootah, Executive Vice President of Generation (Power & Water) at DEWA, noted that after installing any gas turbines, DEWA keeps communicating with the original equipment manufacturers regarding updates and new cost-effective technologies throughout the turbine life cycle.
This increases power generation capacity, efficiency, and reliability, and extends the life of the turbines. The life span of the turbines has been extended by 15 years by adopting the concept of repair and reuse to reduce the consumption of natural resources, in line with the UAE Circular Economy Policy.
The report says that DEWA has broken the world record it set in 2019 for the length of a major inspection outage for the overhaul of gas turbines and desalination units.
DEWA has reduced the maintenance outages for major inspection operations from 11 days to 9 days, which is a reduction in the maintenance duration of 18% compared to the previous world record and an 84% decrease compared to 2006. This has helped DEWA achieve 99.51% and 99.83% availability in the summer for the E-Class and F-Class fleets of gas turbines (GT), respectively, which is one of the highest percentages worldwide, the report added.
DEWA kept its world record for how long it takes to maintain desalination units, which went from 21 days to 10 days.
These records resulted in an increase in F-Class GT availability, which equates to an average cost savings of AED 3.55 million per GT per major inspection.
"Besides providing electricity and water services according to the highest standards of availability, efficiency, and reliability, this step contributes to DEWA’s environmental efforts by reducing carbon dioxide emissions by 49,329 metric tonnes per year in addition to the reduction in operational and maintenance costs," concludes the report.
