Industrial Energy Opportunity Assessment – Practical Guide
Executive Summary
A structured guide for identifying, quantifying and prioritising energy-efficiency opportunities in industrial facilities without separating energy performance from production reliability.
How to Use This Guide
Use the stages below as a decision sequence. The output of each stage should be documented before moving to detailed design, procurement or implementation.
Applications: Efficiency by design, Motor/VFD optimisation, Compressed air, Pumping, Heat recovery, Energy monitoring, On-site renewables
Assessment Philosophy
Industrial energy performance must be evaluated together with production, reliability and maintenance. The objective is not simply to identify kWh savings, but to find measures that improve lifecycle performance without creating production risk.
1. Establish the Baseline
Reconcile utility invoices, interval data, fuel use and production volumes. Define normalisation variables and identify missing or unreliable data.
2. Map Significant Energy Users
Create an energy balance covering motors, pumps, fans, compressed air, refrigeration, process heat, steam, furnaces, HVAC and other major systems.
3. Inspect Operations Before CAPEX
Review schedules, setpoints, idle running, leaks, throttling, maintenance condition, sequencing and operator practices. Many opportunities are operational rather than capital-intensive.
4. Analyse Electrical Performance
Review peak demand, load factor, power factor, harmonics, voltage quality, transformer loading and major motor/drive behaviour.
5. Analyse Thermal Performance
Where relevant, review combustion, steam, condensate, insulation, heat recovery, process temperatures and opportunities for electrification or heat integration.
6. Evaluate Generation and Flexibility
Screen on-site PV, BESS, demand response, CHP where appropriate, microgrids and load shifting against the site's operating profile.
7. Build the Opportunity Register
For every measure record technical concept, baseline, expected savings, CAPEX range, implementation complexity, production impact, dependencies and owner.
8. Prioritise With More Than Payback
Use lifecycle value, operational risk, resilience, maintenance, carbon reduction and strategic fit in addition to simple payback.
9. Define Measurement and Verification
Set measurement boundaries, baseline adjustments, data source, verification period and accountable owner before implementation.
10. Create the Implementation Roadmap
Sequence no/low-cost measures, quick wins, planned shutdown work and larger capital projects. Integrate the roadmap with maintenance and production planning.
