EWEC achieves 98.5 per cent in State Estimator Quality Index for delivering world-leading grid supply
New benchmark driven by EWEC’s strategic implementation of Energy Management System technologies for efficiency and reliability in power supply
EWEC (Emirates Water and Electricity Company), a leading company in the integrated coordination of planning, purchasing, supply, and system despatch services for water and electricity across the UAE, has achieved a rating of 98.5 per cent in the State Estimator (SE) Quality Index, making EWEC the top utility for Energy Management Systems accuracy in the Middle East and North Africa (MENA) paving the road for high grid performance and reliability. This achievement underscores EWEC’s commitment to delivering strategic, cutting-edge grid performance, reliability and operational excellence through advanced Energy Management System (EMS) technologies.
The SE Quality Index, provided by the Supervisory Control and Data Acquisition (SCADA) system, measures the accuracy and reliability of real-time data used in grid operations. Accurate State Estimation is essential for delivering efficient and stable grid management, ensuring energy security for consumers, and enabling further decarbonisation through enhanced operational efficiencies.
EWEC’s 98.5 per cent SE Quality Index rating is the highest achieved by any utility company in the MENA region, and among the leading scores globally. This achievement reflects EWEC’s ability to optimise real-time data for dynamic grid management, maintain a robust power supply through consistent data availability, enhanced system security, and optimised EMS applications, enabling world-class grid management and ensuring continued industry-leading performance. Moreover, this foundation paves the way for the integration of advanced tools leveraging AI technologies to further enhance operational efficiency and innovation.
Easa Alzarooni, System Operations Executive Director at EWEC, said: “EWEC is accelerating the strategic decarbonisation of power and water supply in Abu Dhabi and the UAE while ensuring the security of supply. Achieving the highest SE Quality Index rating across MENA, and one of the highest ratings in the world, demonstrates our dedication to modernising infrastructure and establishing global benchmarks for grid management and performance. Effectively integrating innovative solutions is essential to the nation’s energy transition and highlights EWEC and the UAE as global pioneers at the forefront of securing a zero-carbon future while ensuring seamless energy system operations.”
The integration of advanced technologies that more accurately estimate grid demand and improve response times to fluctuations is essential as EWEC increases the integration of renewable energy sources, such as solar and wind. Given the inherent intermittency of renewables, improved grid management systems are vital for accurate demand estimation and rapid adaptation to changes. These advancements ensure the UAE’s energy supply remains reliable while supporting the nation’s decarbonisation goals and the UAE Net Zero by 2050 strategic initiative.
