In today’s world, organisations are increasingly focused on improving energy efficiency and reducing energy costs. Power quality management is one crucial but often overlooked area that can lead to significant energy savings. Power quality refers to maintaining a clean and stable electrical power supply to equipment—poor power quality results in equipment inefficiencies, failures, and downtime. A comprehensive power quality management strategy can enhance performance by optimising energy use.
The Impact of Power Quality
Power quality issues are more common than many realise. The typical facility experiences more than 20 power quality disturbances per year. These include interruptions, sags, surges, harmonics, and more. Poor power quality leads to:
When supplied with poor-quality power, equipment components work harder to operate correctly. This leads to increased energy consumption and operating costs. Even minor improvements in power quality can drive meaningful energy efficiency gains.
Reduced Equipment Lifespan
Frequent power quality issues stress equipment and accelerate wear and tear. This shortens equipment lifespan, leading to premature failure. Proactively managing power quality extends asset lifespan.
Lost Productivity from Downtime
From small momentary events to prolonged outages, power quality problems inevitably cause downtime. The average facility experiences over 112 hours of downtime annually due to power quality issues. Avoiding downtime through power quality management optimises productivity.
Implementing a Power Quality Management Strategy
A systematic and proactive management strategy is required to realise the benefits of optimised power quality fully. Key elements include:
Monitoring and Analysis
Ongoing power quality monitoring provides the data to identify issues, characterise disturbances, and pinpoint root causes. Detailed analysis guides the selection and targeting of solutions.
Power conditioners and uninterruptible power supplies buffer between sensitive equipment and problem power. They filter disturbances, suppress surges, and deliver clean power.
Smart Load Management
Strategically balancing loads and scheduling the operation of large motors and other inductive loads prevents many power quality issues. This requires monitoring and control capabilities.
Once problems are identified, mitigation measures can be targeted for maximum benefit. Typical solutions include installing surge protective devices, filters, reactors, isolation transformers, and power factor correction units.
Power quality management systematically maintains clean and stable power to elevate equipment performance and energy efficiency. The payoff includes reduced energy consumption, optimised productivity, extended asset lifespan, and downtime avoidance. Organisations can realise substantial benefits through improved power quality by proactively monitoring, analysing, and mitigating power system issues.
Overcoming Implementation Challenges
Transitioning to an active power quality management strategy presents some common implementation challenges:
Gaining organisational stakeholder support for power quality initiatives requires building a compelling business case backed by data. Quantifying the energy savings and productivity gains possible helps secure buy-in.
Upfront investments in power monitoring equipment, mitigation solutions, and other infrastructure may be required. Focusing on the solid ROI from energy and productivity improvements helps overcome budget hurdles.
Lacking In-House Expertise
Most facilities need specialised power quality expertise. Third-party energy services consultants can provide turnkey solutions from assessment to monitoring to targeted mitigation.
Disruption to Operations
Power quality solutions like equipment installation can disrupt facility operations. Careful planning and scheduling during downtimes and maintenance outages mitigate this.
Achieving compatibility, interoperability, and cybersecurity for power quality monitoring and control systems introduces some complexity. Seeking expert guidance and utilising standards helps overcome this.
Realising the Potential of Power Optimisation
While power quality management presents challenges, the potential rewards make overcoming these obstacles worthwhile. With persistent engagement across an organisation, barriers can be addressed. The full benefits of optimised power can be achieved by championing power quality initiatives and targeting solutions correctly.
The future is bright for organisations that embrace proactive power quality management. They stand to gain improved energy efficiency, equipment longevity, productivity, uptime, and operations. While the journey requires commitment, the destination is well worth the effort. By elevating power quality, performance reaches new heights.
Power quality optimisation represents a tremendous opportunity for facilities to elevate performance. While poor power quality drags down energy efficiency and equipment longevity, proactive management reverses this. Organisations can overcome implementation barriers with robust monitoring, targeted mitigation, and a systematic approach. Installing solutions like a power factor correction unit price at a competitive price point helps mitigate this. The reward is enhanced uptime, productivity, sustainability, and competitiveness. As power quality management becomes a priority, facility performance reaches new heights through energy optimisation. The future is bright for organisations committed to realising the full potential of their electrical systems.
