Reliability of Supply (RoS)

RoS refers to our ability to consistently supply the community with needed water and electricity without full stop of our fundamental business priorities.

ACWA Power has implemented a comprehensive RoS enhancement programme in 2023 to mitigate fleet chronic issues caused by design weaknesses, manufacturing flaws, installation QC defects and commissioning issues. The programme aims to enhance the asset lifecycle management process, increase asset availability and improve operational reliability. The implementation scope has covered different technologies, including PV, CSP, RO, thermal, and CCGT plants, with over 300 mitigation actions that have been discussed, validated, agreed, planned and executed in proper alignment with all stakeholders, within more than 40 different plants.

Implementing the RoS enhancement programme has led to the elimination of all targeted chronic issues, which resulted in a significant reduction in the percentage of Forced Outages (FO), compared to the same period last year, and consequently enhanced our asset’s availability and reliability.

Also, during 2023 and in line with the twelve fundamental pillars of the ACWA Power framework that promotes proactive asset management, we launched an O&M critical systems mitigation plan that mitigates the critical failure modes that may lead to significant loss of major equipment. The plan covers 45 different systems with mitigation actions designed to, and based on, international standards, best practice and Enhancing Energy System Reliability (EPRI) technical procedures. Implementing this plan has enabled the O&M team to address the reliability risks in a structured approach and allocate the mitigation resources more effectively, reducing operational events within the O&M systems considered in the plan.
