Energy Audit & Optimization
Our energy audit services help clients evaluate energy performance, identify inefficiencies, and implement improvement measures.
We aim to reduce operational costs while improving productivity and environmental compliance.
Scope Includes:
- Thermal and electrical energy balance
- Boiler and turbine performance analysis
- Process loss identification
- Power factor and load studies
- Energy-saving recommendations
What an Energy Audit Establishes
Most plants know what they spend on energy and far fewer know where it goes. An energy audit closes that gap by measurement rather than estimate: a thermal and electrical energy balance accounts for energy entering the plant against energy usefully delivered, and attributes the difference to specific, identified losses — flue gas, blowdown, radiation, steam leaks, motor inefficiency, distribution losses.
That balance is what makes the rest of the audit credible. Boiler and turbine performance analysis establishes how the two largest energy converters are actually performing against design. Process loss identification finds where energy is being consumed without producing useful output. Power factor and load studies address the electrical side, where poor power factor raises both distribution losses and, in most tariff structures, the bill itself.
The output is a set of energy-saving recommendations, each traceable to the measurement that identified it. That traceability is the point: recommendations derived from a measured energy balance can be evaluated on their merits, while recommendations derived from benchmarks alone cannot be distinguished from guesses.
Energy audits also serve as a starting point. They establish across the whole plant which systems carry recoverable loss, which is what determines where a deeper study is justified.
Where an audit identifies a specific plant worth examining in depth, it is typically followed by power plant efficiency improvement studies. Audits of steam, air, water and cooling systems connect directly to our utility system engineering work. See our recent projects.
Energy Audit & Optimisation — Frequently Asked Questions
What is an industrial energy audit?
An energy audit evaluates how a plant actually uses energy, identifies where it is lost, and quantifies the measures that would recover it. The scope covers thermal and electrical energy balance, boiler and turbine performance analysis, process loss identification, power factor and load studies, and a set of costed energy-saving recommendations.
What is the difference between an energy audit and an efficiency improvement study?
An energy audit establishes where energy is going across the whole plant and what could be recovered. An efficiency improvement study goes further into a specific plant or system — benchmarking performance, assessing equipment health and retrofitting options, and evaluating the result after implementation. Audits are frequently the starting point that identifies which systems justify the deeper study.
What does a thermal and electrical energy balance show?
It accounts for energy entering the plant against energy usefully delivered, with the difference attributed to specific losses — flue gas, blowdown, radiation, steam leaks, motor inefficiency, distribution losses. Without that balance, energy-saving proposals are estimates rather than measurements.
Why does power factor matter to operating cost?
Poor power factor increases the current drawn for the same useful work, raising distribution losses and, in most tariff structures, attracting a penalty. Power factor and load studies establish whether correction is warranted and where it should be applied.
What do you receive at the end of an energy audit?
A set of energy-saving recommendations supported by the measured energy balance and performance analysis behind them — identifying the inefficiencies found, the measures that address them, and the basis on which each was assessed.
Does an energy audit interrupt plant operation?
The measurement work is carried out on the operating plant, since the purpose is to capture how it performs in normal service. An audit conducted on a plant at atypical load does not represent how it actually runs.
