Energy Performance Optimisation

Energy is one of the largest operating costs for industrial facilities, yet many organisations remain unaware that a significant proportion of the electricity they purchase is not used efficiently. Hidden within electrical infrastructure are often inefficiencies that quietly increase energy consumption, reduce equipment performance, and add unnecessary operational costs.

Energy performance optimisation is a specialist area within Exantri’s industrial performance framework, focused on identifying and addressing inefficiencies within electrical power systems. By analysing how electrical energy flows through a facility and how it interacts with operational equipment, it is possible to uncover opportunities to improve efficiency, stabilise power quality, and enhance the reliability of critical assets.

Modern manufacturing environments rely on complex electrical networks that power everything from motors and pumps to robotics, automated production lines, and digital control systems. Over time, the introduction of variable speed drives, high-frequency equipment, and non-linear electrical loads can introduce disturbances within these systems. These disturbances often go unnoticed but can lead to increased energy consumption, reduced power quality, and additional strain on electrical infrastructure.

Through targeted analysis and the integration of advanced energy optimisation technologies, these issues can be addressed, allowing facilities to operate more efficiently and sustainably.

Many industrial sites experience electrical inefficiencies without realising it. These can manifest in several ways, including:

• Voltage instability that causes equipment to draw more power than necessary
• Poor power factor that results in increased electrical demand and utility penalties
• Harmonic distortion introduced by modern electronic equipment that reduces electrical system efficiency
• Unbalanced electrical loads that place additional strain on infrastructure and equipment
• Unmonitored power quality fluctuations that reduce operational visibility and increase risk

While these issues may not always cause immediate operational failures, they can significantly impact the overall efficiency of a facility and increase long-term operating costs.

Energy optimisation focuses on identifying and correcting these inefficiencies at their source.

Electrical supply voltages delivered to industrial facilities are often higher than the level required for optimal equipment performance. Excess voltage causes equipment to consume more energy than necessary and can lead to increased heat generation and wear within electrical components.

Voltage optimisation technologies regulate and stabilise incoming electrical supply, ensuring that equipment receives the optimal voltage required for efficient operation.

Benefits can include:

• Reduction in overall energy consumption
• Lower electrical losses within infrastructure
• Improved equipment lifespan
• Reduced heat generation in motors and transformers

For many facilities, voltage optimisation alone can deliver energy savings of between 8–15%.

Power factor is a measure of how effectively electrical power is being used within a facility. When power factor is poor, electrical systems draw more current than necessary to perform the same amount of work. This leads to increased electrical losses and can result in penalty charges from energy suppliers.

Power factor correction technologies restore balance within electrical systems by compensating for reactive power demands. This improves electrical efficiency and ensures that energy drawn from the grid is used more effectively.

Benefits include:

• Reduced electricity costs
• Elimination of power factor penalties
• Increased electrical system capacity
• Improved stability of plant power systems

Modern industrial environments rely heavily on electronic equipment such as drives, automation systems, and switching power supplies. These devices introduce harmonic distortion into electrical networks, which can degrade power quality and reduce overall system efficiency.

Harmonics can lead to:

• overheating of electrical components
• nuisance tripping of protection systems
• reduced transformer efficiency
• increased energy losses across the network

Harmonic mitigation technologies filter these distortions and restore electrical stability, ensuring that power systems operate efficiently and reliably.

In many facilities, the quality of electrical power is not continuously monitored. As a result, fluctuations, disturbances, and inefficiencies can go undetected until they begin to impact production or equipment performance.

Advanced monitoring technologies provide real-time visibility into electrical behaviour across a facility. This allows organisations to:

• identify inefficiencies in electrical infrastructure
• detect anomalies before they impact operations
• improve operational decision-making
• build a clearer understanding of energy usage patterns

This visibility forms a critical foundation for long-term energy management strategies.

While the immediate goal of energy optimisation is to reduce electricity consumption, the benefits often extend far beyond simple cost savings.

Organisations that optimise their electrical infrastructure frequently experience improvements in several key operational areas.

Energy savings of 8–20% are commonly achievable depending on the nature of the facility and the inefficiencies identified. For energy-intensive industries, this can represent substantial annual cost reductions.

Electrical instability and poor power quality place unnecessary stress on motors, drives, transformers, and other electrical components. By stabilising power systems, facilities can reduce equipment wear and improve reliability.

Improving electrical efficiency can effectively free up capacity within existing electrical infrastructure. This can allow organisations to support future production expansion without the need for costly electrical upgrades.

Lower energy consumption directly translates into reduced carbon emissions. Energy optimisation therefore plays an important role in supporting corporate sustainability goals and environmental targets.

Improved monitoring and analysis of electrical performance provides organisations with valuable insight into how energy is consumed across their operations, enabling more informed strategic decision-making.

Energy performance optimisation should not be viewed as an isolated intervention. Within modern industrial environments, energy efficiency, equipment performance, and operational intelligence are closely interconnected.

Within Exantri’s industrial performance framework, energy optimisation forms part of a wider approach that combines:

• electrical efficiency improvements
• machine performance analytics
• predictive maintenance technologies
• digital asset intelligence

By integrating these elements, organisations can move beyond isolated improvements and instead develop a comprehensive strategy for improving overall industrial performance.

Many industrial facilities have already invested heavily in modern equipment and automation technologies, yet the efficiency of the underlying electrical infrastructure is often overlooked.

Addressing these hidden inefficiencies represents one of the most effective ways to reduce operational costs, improve equipment performance, and enhance the resilience of industrial operations.

Through specialist analysis and the integration of proven optimisation technologies, organisations can unlock meaningful improvements in both efficiency and long-term operational sustainability.
