DEWA Breaks World Record in Inspection Outage Duration for Maintenance

Dubai Electricity and Water Authority (DEWA) has announced breaking its world record in major inspection outage duration for the overhaul of gas turbines and desalination units which DEWA recorded in 2019.

This new achievement promotes DEWA’s position as a globally leading sustainable model for the overhaul of gas turbines and desalination units.

DEWA has reduced the maintenance outages for key inspection operations from 11 days to 9 days, which is a reduction in the maintenance duration of 18%, compared to the previous world record achieved and an 84% decrease compared to 2006.

This has helped DEWA achieve 99.51% and 99.83% availability in the summer of 2021 for the E-Class and the F-Class fleet of Gas Turbines (GT), respectively which is one of the highest percentages worldwide.

DEWA sustained its global record in maintenance of desalination units from 21 days to 10 days. These records resulted in an availability increase of 21 days for each major inspection of F-Class GT.

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 tonnes per year in addition to the reduction in operational and maintenance costs.

HE Saeed Mohammed Al Tayer, MD & CEO of DEWA, highlighted DEWA’s commitment to achieving the wise leadership vision to make Dubai a role model for the efficiency, reliability, and availability of water and energy.

"DEWA also plays a role in consolidating Dubai’s leadership in providing an advanced infrastructure according to the highest international standards to achieve sustainable development and make Dubai a hub for entrepreneurs and investors worldwide.

“The Jebel Ali Power Plant and Water Desalination Complex, the largest single-site complex for energy generation using natural gas in the world, according to Guinness World Records, adopts the best international technologies, and latest advanced smart devices."

In 2019, a team of DEWA’s engineers, led by Emirati experts, and in cooperation with Siemens, co-developed the world’s first thermodynamic Digital Twin Gas Turbine (GT) Intelligent Controller, which uses AI and machine learning.

The turbine is located at M-Station in Jebel Ali, which is the largest power generation and water desalination plant in the UAE. The Intelligent Gas Turbine Controller has improved turbine efficiency, increased its generation capacity, and reduced fuel consumption and harmful emissions.
