What Nomac does

Acwa Operations (formerly NOMAC, First National Operations & Maintenance Company) is a wholly owned subsidiary of ACWA Power that delivers operations and maintenance services for utility-scale power generation and water desalination facilities. Founded in 2005 and headquartered in Jeddah, Saudi Arabia, the company operates a fleet of 45 GW of power capacity and produces 8 million cubic meters of desalinated water per day across more than 14 countries in the Middle East, Africa, Central Asia, China, and Southeast Asia. Its service portfolio spans end-to-end O&M, technical advisory, performance monitoring and optimization, outage management, reliability and efficiency improvement programs, and spare parts planning and logistics, serving both internal ACWA Power assets and external third-party clients.

The company's core technology is the centralized Monitoring and Prognostics Center (MPC), which combines digital twins, machine learning, and real-time data analytics to anticipate equipment behavior and operational risk across the fleet. The MPC is operational in Saudi Arabia and the UAE and is being extended into Central Asia. Acwa Field Services (formerly NMES), the in-house non-OEM service division, complements MPC by delivering outage management, on-site machining, valve repair, and rapid-response maintenance, with commercial interventions growing from 91 in 2023 to a projected 170 in 2025.

Revenue is generated through long-term managed services contracts, with the parent noting approximately 85% of revenue is secured by sovereign-backed, inflation-indexed PPAs and WPAs spanning 20 to 35 years. Distribution is a mix of captive (ACWA Power portfolio) and third-party direct enterprise field sales, with new regional offices in Tashkent, Shanghai, and Johannesburg supporting geographic expansion.

Broad incumbents

• Engie: Global multi-utility with extensive power and water asset ownership and in-house O&M capability; competes broadly with Acwa Operations as a full-portfolio utility services operator, though at much larger scale and broader scope.
• GE Vernova: OEM with one of the largest power-plant service franchises globally, including outage management, repairs, and digital monitoring — competes directly with Acwa Field Services for heavy-equipment maintenance workloads.
• Mitsubishi Power: OEM of gas and steam turbines with extensive aftermarket and long-term service agreement businesses in the Middle East — competes with Acwa Field Services for outage and major-equipment maintenance scope.
• Siemens Energy: OEM for gas turbines, steam turbines, and grid technology with a substantial service business covering O&M and digital performance optimization — a key competitor to Acwa Operations in OEM and non-OEM service markets.
• Veolia: Global water and environmental services operator with significant desalination O&M exposure; overlaps with Acwa Operations on the water/desalination operations side, though Veolia is a broader environmental services portfolio.
• Suez: International water and waste services company operating municipal and industrial water assets, including desalination plants — comparable to Acwa Operations on the water operations and asset management side.

Direct peers

• Worley Limited: Global energy, chemicals and resources services firm with dedicated operations and maintenance practices across power, water, and industrial infrastructure — directly comparable to Acwa Operations' end-to-end O&M and field services mandate.
• Doosan Enerbility: Korean power OEM and EPC contractor offering plant operations, maintenance, and after-market service for combined-cycle and thermal power assets — closely comparable to Acwa Operations' thermal-power O&M and field-services scope.
• SEPCO III Electric Power Construction: Chinese EPC and O&M provider for thermal power, renewables, and water infrastructure with major MEA footprint — a directly comparable operator of utility-scale power and water assets in geographies overlapping with Acwa Operations.

Regional players

• Orascom Construction: MENA-based EPC contractor with power and water infrastructure exposure across the same geographies as Acwa Operations; an adjacent regional peer rather than a direct O&M competitor.
