AI Cooling Water Optimization

Avoids replacing gas power components on fixed schedules when real operating conditions may allow longer useful life, reducing waste and maintenance cost. Lack of trust in black-box AI recommendations and difficulty detecting sensor calibration problems or overlooked operational inefficiencies. Reduces operational costs and improves efficiency in power generation.

The Problem

“Optimize cooling water and component life decisions in gas power plants using explainable AI”

Organizations face these key challenges:

1

Fixed maintenance schedules ignore plant-specific operating conditions

2

Black-box AI recommendations are difficult for engineers to trust

3

Sensor calibration issues can mimic equipment degradation or efficiency loss

4

Cooling water and thermodynamic inefficiencies are hard to detect continuously

5

Operational data is fragmented across historian, CMMS, and lab or inspection systems

6

Engineering teams spend significant time manually reviewing trends and reports

7

Optimization opportunities are missed because decisions are made conservatively

Impact When Solved

Extend component replacement intervals based on actual usage and degradation signalsReduce maintenance cost and spare-part wasteImprove heat rate and overall plant efficiency through cooling water optimizationDetect sensor calibration drift before it causes bad decisionsIncrease operator trust with explainable AI outputsReduce unplanned outages by identifying abnormal degradation earlierImprove planning for outages, parts inventory, and maintenance labor

The Shift

Before AI~85% Manual

Human Does

  • •Review cooling tower, condenser, pump, and chemistry trends from historian, lab results, and spreadsheets
  • •Set fan, pump, blowdown, and chemical dosing targets using fixed rules and operator judgment
  • •Respond to alarms, poor vacuum, or water-quality excursions with manual operating changes
  • •Schedule sampling, inspections, and cleaning after visible degradation or calendar-based intervals

Automation

  • •No AI-driven analysis or optimization in the legacy workflow
With AI~75% Automated

Human Does

  • •Approve operating changes to fan, pump, blowdown, or dosing targets within plant constraints
  • •Review prioritized exceptions such as suspected tube leaks, sensor drift, fouling, or chemistry risk
  • •Decide maintenance, cleaning, or inspection actions based on AI-flagged performance degradation

AI Handles

  • •Continuously monitor weather, load, cooling performance, and water-quality signals for changing conditions
  • •Predict condenser backpressure, heat-rate drift, and scaling or fouling risk under current operating conditions
  • •Recommend coordinated adjustments to pump and fan staging, blowdown rate, and chemical dosing
  • •Detect and triage anomalies such as tube leaks, biofouling onset, and sensor drift for operator review

Operating Intelligence

How AI Cooling Water Optimization runs once it is live

AI runs the first three steps autonomously.

Humans own every decision.

The system gets smarter each cycle.
