Overview

Power generation facilities — including gas turbines, diesel generation, and associated balance-of-plant systems — require continuous monitoring of efficiency, fuel consumption, and equipment condition. MesoAxis works with operations teams to assess how these systems are performing relative to design and where improvements are achievable.

Generation assets in Iraq and the Kurdistan Region span a wide range of unit ages and technologies, from recently commissioned combined-cycle units to older simple-cycle and diesel generation that has been adapted to changing fuel availability and grid demand over time. Units are frequently dispatched at part-load to match grid requirements, which shifts their operating point away from the efficiency levels achieved at rated output.

Balance-of-plant systems — cooling, fuel handling, ventilation, and auxiliary power distribution — are often sized for the original design capacity of the plant and continue operating at that level even when generation output has changed. Maintenance on major rotating equipment is generally planned around manufacturer intervals, but auxiliary systems receive less consistent attention and can accumulate efficiency losses that are not visible in unit-level performance reporting.

Key Challenges

  • Generation equipment operating outside optimal efficiency points due to load variation
  • Auxiliary systems such as cooling, fuel handling, and ventilation consuming significant parasitic load
  • Aging balance-of-plant equipment with deferred maintenance
  • Limited real-time visibility into unit-level efficiency and performance trends

Typical Inefficiencies

  • Auxiliary motors, pumps, and fans running continuously regardless of unit load
  • Cooling and ventilation systems sized for peak conditions but operating year-round at full output
  • Electrical distribution losses within the plant's own auxiliary power systems
  • Heat recovery opportunities from exhaust and cooling systems not being captured
