AI Thermal Network Optimization
Machine learning for thermal energy distribution network efficiency
The Problem
“Optimize thermal networks amid volatile demand and prices”
Organizations face these key challenges:
Inaccurate short-term heat demand and return temperature forecasts drive conservative overproduction and higher heat losses
Local, rule-based control of pumps/valves and generators causes suboptimal system-wide ΔT, elevated return temperatures, and higher pumping power
Limited visibility into network anomalies (leaks, bypassing substations, sensor drift, fouling) leads to slow diagnosis, customer complaints, and avoidable downtime
Impact When Solved
The Shift
Human Does
- •Review SCADA trends, weather outlook, and recent demand to estimate next-day heat production needs
- •Set boiler, CHP, heat pump, storage, pump, and valve targets using rules, seasonal curves, and operator judgment
- •Adjust network pressure, flow, and temperature settings during the day to respond to demand swings and service issues
- •Investigate customer complaints, abnormal return temperatures, and suspected leaks or equipment problems
Automation
- •Provide basic alarms, trend displays, and historical data views for operator review
- •Support offline engineering studies and periodic simulation-based troubleshooting
- •Generate standard reports on energy use, temperatures, pressures, and equipment status
Human Does
- •Approve operating strategy, cost-emissions tradeoffs, and control limits for daily and intraday optimization
- •Review and authorize major dispatch changes during abnormal weather, outages, or market conditions
- •Handle exceptions flagged by the system such as suspected leaks, sensor issues, or constraint conflicts
AI Handles
- •Forecast short-term heat demand, return temperature, and peak risk using weather, historical load, and operating context
- •Optimize coordinated setpoints across generation, storage, pumps, and valves to minimize cost, emissions, and losses within service constraints
- •Continuously monitor network performance, delta-T, pressure, and equipment behavior to detect anomalies and emerging reliability risks
- •Recommend or execute real-time control adjustments and storage charge-discharge actions as conditions change
Operating Intelligence
How AI Thermal Network Optimization runs once it is live
AI runs the operating engine in real time.
Humans govern policy and overrides.
Measured outcomes feed the optimization loop.
Who is in control at each step
Each column marks the operating owner for that step. AI-led actions sit above the divider, human decisions and feedback loops sit below it.

Approval, override, feedback
AI senses, optimizes, and coordinates in real time. Humans set policy and override when needed. Measurements close the loop.
The Loop
6 steps
Sense
Take in live demand, capacity, and constraint signals.
Optimize
Continuously compute the best next allocation or action.
Coordinate
Push those actions into systems, channels, or teams.
Govern
Humans set policies, objectives, and overrides.
Authority gates · 1
The system must not make major dispatch changes during abnormal weather, outages, or unusual market conditions without control room operator or operations manager approval. [S1][S3]
Why this step is human
Policy decisions affect the entire operating envelope and require organizational authority to change.
Execute
Run the approved operating loop continuously.
Measure
Measured outcomes feed back into the optimization loop.
