Fixed rates, variable demand
Blowers, pumps, and drives are often run at fixed rates set for the worst case. The process rarely needs the worst case, so the margin is burned as energy, every hour of every shift.
Energy is a process variable. Control it like one.
Most plants treat energy as a fixed cost of running. It isn't. When the platform holds your process at its most efficient operating point, energy per ton produced comes down the same way variability does: continuously, measurably, without new capital equipment. The same discipline that lowers your energy bill also lowers what you report on emissions and resource use, one operational change, two outcomes.
Where the energy goes
Variability is an energy bill you never see itemized.
Every time a process drifts off its best operating point, something compensates: more air, more steam, more pumping, more reprocessing. In industrial wastewater, aeration alone consumes more than 50% of a plant's energy budget. The waste isn't a single failure. It's the running cost of operating away from the setpoints your own best runs already proved out. Increasingly, that waste shows up on two different desks: the plant controller's energy line item, and the sustainability team's emissions inventory.
Drift compounds the cost
An off-center process needs more energy to make the same on-spec product. Off-spec product needs energy twice: once to make it, once to rework or replace it.
Nobody has time to chase it
Operators are running quality and throughput. Re-optimizing setpoints for energy every 15 minutes is not a job a person can do on top of that. It's a job for the AI platform.
Fixed-rate vs. demand-driven
Stop paying for capacity the process isn't asking for
The platform learns what your process looks like on its best runs, then holds key variables at those golden-run targets in real time. Energy use follows what the process actually needs, not a rate someone set months ago.
Before / Fixed-rate operation
Set for the worst case
Equipment runs flat-out so nobody gets caught short. Demand varies. The rate doesn't.
- The gap is pure waste. Energy above demand does no useful work.
- Setpoints go stale. Rates tuned for last quarter's conditions keep running this quarter.
- Nobody sees it. The bill shows total consumption, not which hours were unnecessary.
After / Demand-driven setpoints
Held at the efficient point
Setpoints track golden-run targets in real time, so supply follows actual demand.
- Golden-run centerlining. Key variables held at the targets your best runs already proved out.
- Recommendations every 15 minutes, only when the process moves out of bounds.
- Energy per ton falls with variability. Same product, same equipment, less input.
Proof case / Industrial wastewater
Aeration: over half the energy budget, under real-time control
Industrial wastewater is the clearest test of energy as a controllable variable. Aeration consumes more than 50% of a wastewater plant's energy budget, and blowers are commonly run at fixed rates regardless of actual biological demand. In a ProcessMiner wastewater deployment, holding the process at its efficient operating point improved sludge cake dryness from 13% to 20%, which means less water hauled, dried, and disposed of downstream. The same discipline that improved dryness governs aeration: supply what the process needs, when it needs it.
Reduce quality variability
See quality drift as it starts, not after the lab confirms it. Hold the process closer to target, run after run, so quality stays consistent instead of swinging between the guardrails.
Optimize for what matters
Improve quality, cut chemistry and energy waste, and lift throughput — the outcomes that show up on the bottom line. ProcessMiner turns your process data into the specific moves that get you there.
Built on your team's expertise
You know your equipment and your product. ProcessMiner brings the process intelligence and puts it directly in your operators' hands — no coding, no rip-and-replace. Speed to value, built on the knowledge your team already has.

Sustainability, not a separate initiative
The efficiency case and the sustainability case are the same case.
Manufacturers increasingly have to report on energy intensity and resource use, not just cost. ProcessMiner doesn't require a separate sustainability program to do that. The same centerlining and prediction that hold quality also hold energy, water, and chemistry closer to what the process actually needs, so the numbers that go into an ESG report move in the same direction as the numbers that go into a P&L.
Less energy, same output
Energy per ton falls with variability, not through new equipment or a capital project.
Less water and chemistry wasted
In wastewater, better-controlled dosing and the dryness improvement already measured (13% to 20%) mean less material hauled, treated, and disposed of.
One data trail, not two
The same historian connection and models that report operational KPIs can supply the energy and resource figures a sustainability report asks for, instead of a parallel manual data-collection effort.
How the platform gets there
Three capabilities, one result: less energy per ton
Energy efficiency isn't a separate module. It's what falls out when quality prediction, centerlining, and optimization keep the process where it runs best.
01 / Intelligent Centerlining
Find the efficient point. Then hold it.
Your best runs already exist in your historian. Centerlining identifies the golden-run targets behind them and aligns key process variables to those targets in real time, on a live radar-style dashboard, so the process stops paying the energy premium of running off-center.
- Targets derived from your own proven best runs, not a theoretical model
- Live view of which variables are on target and which are drifting

02 / Real-Time Prediction
Catch the drift before it costs you
Quality predictions refresh every 30 seconds, so the platform sees the process leaving its efficient operating point before a lab result or an energy bill would tell you. Corrective recommendations arrive every 15 minutes, and only when the trend is actually out of bounds.
- Quality predictions every 30 seconds, recommendations every 15 minutes
- Less drift means less compensating energy: air, steam, pumping, rework
- Explore Real-Time Prediction
Reactive vs. proactive
03 / Autonomous Optimization
From recommendations to closed-loop control
When your team is ready, the platform can write validated setpoint corrections back to the DCS itself, holding the efficient point around the clock without waiting on a person to act. Adoption is gradual and the operator stays in control: autonomy is toggled off during grade/SKU transitions and re-enabled after stabilization.
- The platform recommends; operators act. Trust is built on results.
- Autonomy runs 1–2 hours per day on selected variables.
- 8+ hours per day as confidence grows across shifts.
- Around-the-clock control, with operators toggling off during grade/SKU transitions.
