Why modern UPS systems still require proactive maintenance
Stringent manufacturing processes and tighter quality control means modern UPS systems are more reliable and less likely to fail than those containing older technology. Older, analogue UPS systems often experienced drifting values and input currents across phases that would need onerous balancing. As UPS technology has moved towards digital processors (DSP), there is less of a need to regularly calibrate the units.
It can be argued that a new uninterruptible power supply, housing the latest UPS technology should not require servicing per se during the warranty period, so what is the point in having a service or preventative maintenance contract?
Whilst the UPS unit itself may be considered reliable, there are a number of extraneous variables that can affect the performance of the UPS systems in the long term. Variables such as adverse environmental conditions that a preventative maintenance visit would identify before they cause harm to the system – even if that problem won’t manifest for a few years. Uninterruptible power supplies by their very nature must provide a reliable supply of uninterrupted power if, and when, required.
Rob Mather, Solutions Director at Power Control says: “Many businesses fall into the trap of a false economy. Anything that can affect the reliability and performance of the UPS system that is not addressed, negates the purpose of having a UPS in the first place.”
Believing that money will be saved by not investing in a reliable service contract means there is a risk of not identifying and addressing a potential fault, possibly causing £thousands of downtime and broken machinery.
Whilst modern digital signal processor (DSP) controller units do not suffer from the calibration drifts of legacy analogue units, there are other reasons an annual preventative maintenance visit at the very least. Firmware updates are crucial for ensuring the UPS system is working at peak performance. The revisions come in numerous forms, from having different settings available on a monitoring tool, to preventing a loss of load in a certain scenario.
Firmware updates are released to counter and remove any abnormalities found in certain conditions and reported to the manufacturers R&D team. A new firmware may also be released if in certain applications the UPS requires a different setting to be available. Not every firmware revision will be applicable to improving the performance of all uninterruptible power supplies, but it could impact the longevity of a UPS, or affect warranty status.
As a result, a service contract will offer additional reassurance in the form of knowing an alternative power supply will protect the critical infrastructure of a business in the event of a power failure. Most maintenance providers will offer an emergency callout facility with varying response times, generally from a 4hr response time to the next business day depending on the service level agreement (SLA).
This provides peace of mind that a potential failure will be identified and resolved before a problem occurs.
Whilst the UPS system is still under warranty, it is advised that either the manufacturer or the company who provided the UPS, maintain the UPS. Although third parties may be capable to maintain the unit, any warranty claim could be protracted as the end user may be required to prove to the manufacturer that the UPS has been correctly maintained.
Once a UPS is no longer covered under warranty, it is advised that a service provider is thoroughly checked to ensure that they have the resources available to deliver on any promises made by the sales team. Questions should be asked about what will happen in certain scenarios; does the company have spare parts, do they have access to firmware updates, do they subcontract to the manufacturer, what is their stock of new UPS systems and do they include callouts and parts?
An all-inclusive maintenance contract will cost more initially but there are no hidden costs, alternatively, a basic contract will be more cost effective but there could be large repair bills if the UPS fails.
Rob Mather commented, “For me, the most important thing to remember is why the UPS was purchased in the first place. Generally, it is to provide business continuity in the event of a mains failure. The actual UPS unit is not important, it is the function provided that is essential. So, with this in mind, the purpose of a preventative maintenance visit is to anticipate a fault before it happens.”
Power Control maintains third-party UPS and backup power equipment, whilst spare parts are available for a plethora of Uninterruptible power supplies, and have engineers experienced and trained on a magnitude of UPS brands; the biggest dimension is the stock availability of replacement and loan UPS systems. If the most important requirement of a UPS is to have business continuity, what does it matter if the failed UPS is replaced rather than repaired if the timescales and costs are similar?

How applicable are data centre tier ratings to UPS system reliability?
Established by the Uptime Institute (TUI) in the 1990s, data centre tiers are a convenient system to organise types of data centre infrastructure based on a set of operating criteria. The classification ranks facilities from 1 (l) to 4 (llll) with 1 being the lowest rank and 4 being the best performing level.
The exact method of assigning tiers is kept a secret by the Uptime Institute however, the most important metrics are common knowledge: Service availability and uptime guarantees, redundancy levels, cooling capacity and power infrastructure, security, staff expertise and maintenance protocols to name a few.
Customers typically use the tiers to help them to decide which facility to trust for their critical data. However, the facility tier rating is not as applicable to the performance of a UPS (uninterruptible power supply) in good working order. A UPS installation can be made to be as robust as necessary irrespective of the facility tier rating. It comes down to what is actually required.
One of the metrics, service availability refers to the five 9’s of uptime. Whilst the 99.9999% availability is a useful metric, it is irrelevant for power availability. A facility could see an outage every day of the year and still fulfil this metric or KPI. For UPS, the metric has got to be for it to fulfil its purpose irrespective of the overall facility tier rating.
The tier rating of the facility will determine what happens when there is an external failure outside of the control of the UPS, such as an issue resulting in no power to the UPS (the batteries only have a finite charge in them and once it’s gone, the load will lose power.) It does not determine what is within the control of the UPS and how the system is made as resilient as possible within the different design configurations.
A more appropriate way to measure and configure UPS is to limit the effects of any faults as far as possible, this is where the tier ratings do have a small impact – fault tolerance and concurrent maintainability.
A UPS will likely have a fault at some point, they are in constant 24/7 operation and are made up of consumable electrical components. The internal makeup of the UPS such as PCB’s, component ratings, airflow designs, etc, are ultimately what can affect the reliability of the single UPS.
Director at Power Control, Rob mather commented “The majority of UPS on the market today are relatively reliable compared to a decade ago. At that time there were some UPS where the reliability of the power would have been improved if the UPS was taken out of a circuit.
There are still differences, but the main commercial forces prevent poor units from gaining any market traction. For this reason, we will focus on how the overall UPS configuration and installation can be done to improve the reliability of achieving a supply to the load 100% of the time.”
A major cause of UPS faults is the batteries. Batteries are often an overlooked aspect of the overall UPS design, yet if they are done wrong, it has a huge impact on the ability of the UPS to support the load and potentially causes a fire risk.
Rob Mather commented “For this reason, I am always surprised when there is an installation with a common battery that has no redundancy but N+1 of UPS. Whilst this sort of installation makes maintenance easier, it does not really improve the reliability of the system considering that general batteries are more likely to be the cause of a fault than the UPS.”
How to increase UPS reliability
Design the UPS to be operated at a maximum 80% capacity. Constant operation higher than this will result in more wear and tear on components which mean the efficiency of the UPS will degrade sooner, and potentially result in needing to replace consumable items sooner. There are numerous reasons for doing this, and the only reason for not is cost. Furthermore, nearly all modern UPS will be more efficient at 80% load than 100% anyway.
Consider multiple battery strings with redundancy if having a single UPS system.
If only installing a single UPS system, consider a modular UPS with a redundant module, and redundant battery string. Or have an N+1 UPS system each having its own batteries, this means that maintenance can be carried out and in the event of a fault the load should remain protected.
Is it feasible to have a 2N installation from the UPS down?
Even if there is only a single main supply and LV panel available, splitting the supplies from the UPS will add an increased level of resilience. This will not be a full tier III infrastructure but is going to make the supply of UPS backed power more reliable without the full expense. This will enable concurrent maintainability for the UPS systems and provides redundancy in the event of a fault on the UPS.

Battery back up Required for Video Assistant Referees (VAR) - FIFA Issues Letter to all Premiership Clubs
Football match technology has advanced significantly over the last decade. One of the biggest advancements has been the introduction and widespread use of Video Assistant Referees (VAR) to help officials make more accurate and consistent decisions.
What is VAR and Goalline technology?
Developed in 2010 by Royal Netherlands Football Association and making its international debut in 2018 at the FIFA World Cup, VAR allows referees to review video footage of key incidents, such as goals, penalties, and red cards, to ensure that the correct decision is made. A VAR system typically consists of several key components, all of which require a stable and consistent supply of power to operate.
- Multiple high-definition cameras: these cameras are placed around the stadium to capture footage of the match from different angles. The footage is then sent to the VAR room for review
- Communication systems: the VAR team communicates with the on-field referees via a headset.
- Replay system: The VAR uses a replay system to review the footage from the cameras.
- Video monitors: The VAR team used video monitors to view the footage from the cameras.
- Decision making software: The VAR system used specialised software that helps the VAR team to make decisions by tracking the position of the ball, players and officials on the field.
- On-field signal equipment: The VAR team uses on-field signal equipment like a flag, a board with a specific number, or an electronic signal. This indicates to the on-field referee that a decision is being reviewed.
The technology was introduced into the UK Premier League for the 2019/2020 season and has been used consistently since. As technology continues to improve, new components and upgrades may be added to VAR systems in the future.
Another major advancement in football technology has been the use of goal-line technology. This system uses sensors and cameras to determine whether the ball has crossed the goal line and can quickly alert the referee if a goal has been scored. This technology has been used in many major tournaments and leagues worldwide, including the Premier League. Again, goalline technology also requires a reliable supply of power to operate.
What happens to VAR during a power failure?
The drawbacks of both technologies were highlighted in October 2022 when the Leeds United V Arsenal game was halted after a power cut caused issues for both the VAR and goalline technology. Less than a minute after kick-off and with no solution to the problem after 10 minutes, the players were led from the field amid boos from fans. The sensitive VAR equipment can take up to 30 minutes to be brought back online and recalibrated before play can resume.
FIFA issues letter on battery backup for VAR
Following this incident, FIFA issued a letter to all Premier League clubs outlining the requirement for an uninterruptible power supply (UPS) to back up the VAR equipment.
UPS systems may already be present in particular areas of a stadium to support local equipment, for example, in a server room backing up computer systems, access control and floodlighting or in a plant room to support evacuation lifts and life safety systems. The existing UPS infrastructure will be sized to support a specific load in these examples.
While it may be possible to add an additional load from a different area, such as that from VAR and goalline technology, it would involve a UPS specialist checking the sizing of the existing UPS and weighing up the cost of installing a cable run to the location of the VAR equipment. However, it is likely that a new UPS of the correct size will need to be installed.
For this to be determined a site survey is recommended and should be carried out by a competent person such as a technical salesperson from a company specialising in UPS.
Backed by nearly three decades of experience, Power Control has a number of UPS solutions available to stadiums. Since FIFA issued the letter, Power Control has already surveyed and supplied UPS to several major Premier League clubs and continues to do so into 2023.

5 Reasons Why It's Not Just the UPS Batteries That Cause UPS System Failure
In today's digitally-driven world, UPS systems (Uninterruptible Power Supply) play a crucial role in ensuring continuous power supply to critical equipment, safeguarding against power disruptions, and preventing data loss or hardware damage. However, despite the emphasis often placed on the condition of UPS batteries, there are various other factors that can contribute to UPS system failures. Let's delve into five key reasons why UPS systems may fail, beyond just the condition of the batteries.
- Component Wear and Tear
UPS systems comprise various components besides the batteries, including capacitors, fans, transformers, and circuitry. Over time, these components are subject to wear and tear, which can compromise the overall functionality of the UPS system. Capacitors, for instance, may degrade over time, affecting the system's ability to regulate voltage or filter out electrical noise. Similarly, fans can accumulate dust or experience mechanical failure, leading to overheating issues. Addressing regular maintenance and replacing worn-out components proactively can mitigate the risk of system failures due to component degradation.
- Overloading and Improper Sizing
Another common reason for UPS system failure is overloading or improper sizing of the system concerning the connected load. When a UPS is overloaded, it operates beyond its designed capacity, which can result in overheating, voltage fluctuations, and ultimately, system failure. Similarly, if the UPS is undersized for the load it's meant to support, it may struggle to provide adequate backup power during outages, leading to potential disruptions. Properly sizing the UPS according to the anticipated load and periodically reviewing load requirements can help prevent such issues.
- Environmental Factors
Environmental conditions can significantly impact the performance and longevity of UPS systems. Factors such as temperature, humidity, and airborne contaminants can affect the operation of electronic components within the UPS. High temperatures can accelerate component degradation and shorten the lifespan of critical parts like batteries and capacitors. Likewise, exposure to moisture or corrosive elements can lead to rust, electrical shorts, or other damage. Installing UPS systems in controlled environments and implementing measures to regulate temperature and humidity levels can mitigate the impact of environmental factors on system reliability.
- Poor Maintenance Practices
Regular maintenance is essential for ensuring the optimal performance and reliability of UPS systems. However, inadequate or inconsistent maintenance practices can increase the likelihood of system failures. Neglecting routine inspections, battery replacements, or firmware updates can result in undetected issues that may escalate over time. Additionally, failure to adhere to manufacturer recommendations or industry best practices for maintenance can compromise the overall integrity of the UPS system. Implementing a comprehensive maintenance schedule and partnering with experienced professionals for servicing can help identify and address potential issues before they escalate into failures.
- External Factors and Human Error
UPS system failures can also occur due to external factors beyond the control of the system itself. Events such as power surges, lightning strikes, or utility grid fluctuations can overwhelm the UPS's protective capabilities, leading to equipment damage or downtime. Moreover, human error, such as improper installation, accidental disconnection, or failure to follow operational procedures, can also contribute to system failures. Educating personnel on proper handling and operation of UPS systems, as well as implementing additional surge protection measures, can help mitigate the impact of external factors and human error on system reliability.
In conclusion, while the condition of UPS batteries is undoubtedly critical, it's essential to recognise that UPS system failures can stem from various other factors as well. By addressing component wear and tear, ensuring proper sizing, managing environmental factors, maintaining regular maintenance practices, and mitigating external risks and human error, organisations can enhance the reliability and resilience of their UPS systems.
While a regular maintenance plan is highly recommended and by far the best way of determining any causes for concern, an Uninterruptible Power Supply (UPS) health check provides a snapshot of the current health of the UPS system. It typically involves a thorough examination of various components and functionalities of the UPS system to ensure its optimal performance and reliability.

However, behind the scenes, a complex web of technology ensures that each match runs smoothly and fairly. One of the most significant advancements in recent years is the Video Assistant Referee (VAR) system, particularly its application in goal-line technology. This and connected ball technology is being used for the first time at a European Championship, starting with the host Germany’s opening fixture against Scotland in Munich. All 10 of the host’s stadiums are equipped with a goal line technology system.
This system ensures that every goal scored is accurately recorded, preventing controversial decisions, and maintaining integrity of the sport. However, the reliability of this technology hinges on an often-overlooked component: Uninterruptible Power Supplies (UPS), a critical piece of equipment which contributes to the smooth functioning of football matches.
The role of VAR Goal Line Technology
Goal-line technology is a specialised component of the VAR system designed to determine whether the ball has completely crossed the goal line. Using high speed cameras and advanced sensors, the system provides instant feedback to referees, eliminating any doubt about the legitimacy of a goal. This technology has been a game changer, ensuring that critical match outcomes are decided accurately and fairly.
The vulnerabilities of Technology used in Football
While VAR goal-line technology is highly sophisticated, it is not immune to technical issue. Power interruptions however brief, can disrupt the functionality of these systems. A sudden power outage during a match could lead to the technology failing at a crucial moment, potentially resulting in incorrect decisions, and affecting the outcome of the game. This is where uninterruptible power supplies (UPS) come in to play.
What is an uninterruptible power supply (UPS)?
A UPS is a device that provides backup power to electronic systems in the event of a power failure. It acts as a bridge between the primary power source and the technology, ensuring a continuous power supply. Depending on their topology – line interactive or online double conversion, UPS systems are designed to kick in immediately or switch the power source to an already running UPS system, when they detect a power interruption, providing enough power to keep the technology running until the primary power source is restored or a backup generator takes over.
The Importance of UPS for VAR Goal Line Technology
UPS systems ensure that VAR goal-line technology remains operational without interruption, even during power outages. This continuous operation is crucial for maintaining the integrity of match decisions. Downtime in VAR systems can lead to delays in the game, affecting the flow and experience for players and spectators. UPS systems minimise downtime, allowing matches to proceed smoothly.
Following an incident that happened in 2022 during the Leeds United vs Arsenal game, FIFA issued a letter to all premiership clubs outlining the requirements for an uninterruptible power supply to back up the VAR and Goal Line equipment.
Power outages can also lead to data loss or corruption and damage to sensitive electronic equipment. UPS system prevent this by ensuring that all data related to goal-line decisions is securely saved and accessible, prolong the lifespan of the equipment and reduce maintenance costs.
Other Applications of UPS Systems in Football Stadiums
Beyond supporting VAR goal line technology, UPS systems play a crucial role in other critical applications within football stadiums. They ensure that essential systems such as lighting, public address systems, access control, and electronic scoreboards remain operational during power outages, preventing disruptions that could affect the safety and experience of both players and spectators.
Additionally, UPS systems support the operation of security systems, including surveillance cameras and emergency communication networking, which are vital for maintaining safety and order during matches.
In press boxes and media centres, UPS systems ensure that journalists and broadcasters can continue to deliver live coverage without interruptions, preserving the quality of the viewer experience worldwide. These multifaceted applications highlight the indispensable nature of UPS systems in maintaining the seamless operation of modern football stadiums.
As EURO 2024 captivates audiences across the globe, the importance of robust and reliable power solutions like UPS systems in the seamless operation of football matches becomes increasingly clear. Investing in these systems is not just about preventing power outages; it’s about preserving the spirit and fairness of the beautiful game.

Understanding Sine Waves in UPS Systems: Why Pure Sine Wave is the Best Choice
When it comes to uninterruptible power supply (UPS) systems, the type of sine wave output plays a crucial role in determining efficiency, compatibility, and overall power quality. There are primarily two types of sine wave outputs in UPS systems: modified sine wave and pure sine wave. Understanding the differences between these two is essential for businesses and individuals looking to invest in reliable power backup solutions. While both serve the purpose of delivering backup power during outages, they do so with varying levels of efficiency and performance.
Modified sine wave, sometimes referred to as a quasi-sine wave, is a stepped approximation of a pure sine wave. Instead of delivering a smooth and continuous curve, a modified sine wave consists of abrupt changes in voltage, creating a stair-step pattern. This type of waveform is less complex and, therefore, more affordable to produce, making it a common choice in budget-friendly UPS systems and inverters.
However, despite its cost advantages, a modified sine wave has several drawbacks. Many sensitive electronic devices, such as medical equipment, high end audio systems, and certain computers, do not function optimally with a modified sine wave. The abrupt voltage transitions can cause overheating, increased electrical noise, and reduced efficiency in appliances that rely on stable and precise power delivery. Furthermore, modified sine wave UPS systems may produce a noticeable hum in devices with electric motors or transformers, leading to potential performance issues and even long term damage.
On the other hand, pure sine wave UPS systems generate a smooth, continuous wave that closely mimics the standard power supplied by utility companies. This means that the voltage gradually rises and falls in a consistent, uninterrupted manner, ensuring clean and stable power delivery. Because of this, pure sine wave UPS systems are compatible with all types of electronic equipment, including sensitive medical devices, high performance computing systems, and modern home appliances.
The key advantage of a pure sine wave UPS is that it provides stable power that prevents electrical noise, reduces wear and tear on equipment, and ensures maximum efficiency in operation. Unlike modified sine wave outputs, which can lead to overheating and unexpected shutdowns, pure sine wave UPS systems maintain the integrity of connected devices, preserving their lifespan and functionality.
Another significant reason why pure sine wave UPS systems are superior is their ability to support appliances with variable-speed motors, such as refrigerators, air conditioners, and certain power tools. These devices require smooth voltage transitions to operate correctly. If powered by a modified sine wave, they may run less efficiently or fail to start altogether. Similarly, uninterrupted power to high-end computing equipment is crucial in environments such as data centres, where sudden power fluctuations can lead to corrupted files or hardware failure. A pure sine wave UPS ensures that these risks are mitigated, making it the preferred choice for critical applications.
Additionally, battery efficiency is another area where pure sine wave UPS systems excel. Because they provide a more consistent flow of energy, they reduce unnecessary power loss and improve overall battery longevity.
In contrast, the inefficient power delivery of a modified sine wave UPS can lead to increased battery drain, requiring more frequent replacements and increasing operational costs over time.
Ultimately, the choice between a modified sine wave and a pure sine wave UPS should be based on the types of devices being powered and the level of reliability required. While a modified sine wave UPS may be sufficient for basic applications such as running simple household electronics, it falls short when it comes to providing stable and efficient power for sensitive or high performance equipment.
Investing in a pure sine wave UPS ensures peace of mind, protecting valuable devices from potential damage and guaranteeing uninterrupted, high-quality power. As the demand for cleaner and more reliable energy solutions grows, pure sine wave UPS systems remain the gold standard for both residential and commercial applications.
All UPS systems supplied by Power Control, including single phase rack and tower, and three phase modular and monolithic UPS, are pure sine wave. This ensures that every solution provided meets the highest standards of power quality, reliability, and efficiency, making them suitable for a wide range of critical applications across various industries.

The impact of the Labour budget on the UPS industry
The Uninterruptible Power Supply (UPS) market is set to experience continued growth as we head into the new economic year. While the October 2024 budget did not directly address the UPS sector, the broader economic and technological policies unveiled will undoubtedly have an indirect effect on the industry’s growth and demand dynamics.
In the Labour Party’s initial October budget, Chancellor Rachel Reeves acknowledged the transformative potential of technology in driving economic growth. She announced that the Government’s Chief Scientific Adviser (GCSA), Professor Dame Angela McLean and National Technology Adviser (NTA), Dr Dave Smith have been tasked to lead a review into the barriers surrounding the adoption of transformative technologies for enhanced innovation and productivity.
The review will focus on eight key growth-driving sectors; advanced manufacturing, clean energy and creative industries, defence, digital technologies, financial services, life sciences and professional and business services - sectors originally identified in the government’s Industrial Strategy green paper.
The findings, to be published in Spring, will pinpoint the issues businesses are currently facing in their efforts to adopt both new and established technologies and build on from the existing analysis, industry insights and AI Opportunities Action Plan roadmap - the Secretary of State’s recommended plan to drive growth of the AI sector in the UK.
Conclusions will undoubtedly shape government policy for 2025 and beyond, and highlight the key areas for future investment. As has already been discovered through the Industrial Strategy green paper, accelerated technology adoption, particularly in companies beyond those of the country’s recognised frontier firms, could drive significant productivity gains for the UK’s future economy. Funding aimed at reducing these barriers and supporting the wider uptake of innovative technologies is therefore highly likely to be made available for businesses that fit designated sector criteria.
This growing pace of technology adoption is set to significantly impact the future of the UPS industry. The rollout of 5G networks and expansion of cloud services and edge computing increase the need for reliable power solutions that ensure data integrity and prevent downtime.
The proliferation of Internet of Things (IoT) devices is increasing dependency on consistent power supplies that avoid disruption to connected systems – as is the infrastructure that supports these IoT devices, such as data centres etc, that rely on robust backup power solutions capable of handling increased energy demands.
On a global basis, the seismic shift towards a ‘greener’ future is also having a direct impact on the industry. Significant resources have been set aside for renewable energy investments, with £1.1 billion being dedicated to offshore wind projects. This substantial investment in renewable energy infrastructure will drive the need for advanced power management systems, green UPS and backup solutions that help to maintain power stability and address the intermittent nature of renewable energy sources.
Essential components in the facilitation of microgrids that incorporate renewable energy supplies, UPS systems enable the seamless transition between grid power, renewable sources and stored energy.
By acting as a buffer against ‘green’ energy fluctuations, the UPS ensures power stability, providing a continuous electrical flow to local facilities and communities during periods when the renewable energy source is either unavailable or inconsistent. The UPS’s ability to quickly respond to these changes in supply and demand assists in balancing grid frequency, particularly valuable in renewable-heavy grids where the sudden drop in energy production leads to frequency instability.
As many modern UPS solutions are now able to integrate with battery energy storage systems (BESS), they also have the ability to store excess energy generated during peak production times themselves, resulting in a more energy-efficient power protection solution.
With the UK’s commitment to achieving the key energy initiatives outlined in the COP29 Global Climate Summit, we will undoubtedly see the continued growth of energy-efficient technologies – including those in the field of backup power systems.
Modern UPS solutions, particularly those with advanced features such as remote monitoring, predictive maintenance, eco-modes and high-efficiency ratings, are certain to become a more attractive investment amongst companies keen to meet their own sustainability and carbon initiative targets. Businesses looking to replace current legacy systems may however find themselves balancing the higher initial costs of a more premium energy-efficient UPS against potential tax benefits and the longer-term operational savings any new unit will bring.
Conclusion
The economic and technological policies unveiled in October’s budget will undoubtedly see additional demands being placed on the UPS industry.With energy security and digital infrastructure becoming increasingly critical to business operations, the need for superior levels of power resilience has never been greater. As we look towards adopting more emerging technologies and integrate renewable energy sources into existing systems, we must also look towards the power protection strategies that will support them.
While it remains to be seen where future policies and incentives will support further technology investment, companies should seek to maintain flexibility in their procurement strategies, adapting budgetary allocations and adjusting UPS purchasing decisions to support technology adoption as it occurs.

Retrofitting Central Power Supply Systems (CPSS) in Existing Buildings: Challenges and Critical Considerations for Lift Integration
As the demand for improved energy resilience and compliance with modern safety standards continues to grow, an increasing number of building owners and developers are recognising the value of Central Power Supply Systems (CPSS).
These are crucial in maintaining power to essential equipment in the event of a mains failure - particularly in life-safety applications such as emergency lighting, security systems, fire detection, smoke extraction, and perhaps most critically, passenger lifts and elevators.
However, retrofitting a CPSS into an existing building presents a unique set of technical and logistical challenges. This blog takes a look at these complexities and why overcoming them is vital for safety, compliance and operational continuity.
What Is a CPSS?
A CPSS is a specific type of backup power solution designed for use with emergency and safety-related applications.
Unlike a standard Uninterruptible Power Supply (UPS), a CPSS system is designed to cope with significantly greater overload protection and offers enhanced features for life safety applications.
CPSS must adhere to strict criteria as outlined in the BS EN 50171 standard for use with essential safety systems. This covers emergency applications that are permanently connected to AC supply voltages not exceeding 1000V, that use batteries as an alternative power source.
CPSS systems are more typically used in high-rise or commercial buildings, in healthcare facilities and within public transportation environments.
The Challenges of Retrofitting CPSS into Existing Buildings
Retrofitting a CPSS isn’t as simple as plugging in a backup unit. It involves navigating a range of architectural, electrical, mechanical and regulatory hurdles - each one requiring detailed planning and expert execution.
1. Space and Physical Integration
Many existing buildings lack the space for a CPSS system, particularly those that involve large battery arrays and associated control gear. Understanding the physical environment the CPSS solution will be operating in is therefore key to ensuring optimum performance. It is essential that height and weight limitations, ventilation restrictions and the actual space the unit is to be housed in are all taken into consideration.This often requires the use of creative engineering solutions such as repurposing plant rooms, installing mezzanines or designing modular CPSS enclosures that can fit into non-traditional areas, while still ensuring full compliance with ventilation and fire safety standards.
2. Load Mapping and Circuit Identification
Identifying and isolating the critical circuits that must be supported by the CPSS, such as lift motors and control systems, can be difficult due to outdated or incomplete building schematics.Power audits and load testing are therefore essential. Engineers must trace and test each circuit to ensure critical systems can be correctly prioritised and that there is no risk of overloading the CPSS. It is vital that any selected CPSS can handle the total electrical load while also allowing for future growth and expansion. Power Control advises maintaining an additional 20 – 25% capacity to accommodates this purpose.
3. Electrical Infrastructure Compatibility
Legacy distribution boards and wiring systems may not be compatible with modern CPSS units. Retrofitting may involve partial rewiring, upgrading distribution boards or installing power conditioning equipment.Lift control systems, which can be particularly sensitive to power quality issues, may require tailored CPSS configurations to handle high inrush currents during startup, and variable frequency drives (VFD’s) – which are particularly sensitive to voltage dips and harmonics. Any supporting solution must be carefully sized and capable of handling dynamic load profiles.
Why Overcoming These Challenges Is Critical
Despite the complexities surrounding CPSS retrofitting, it is essential that building owners and developers overcome these challenges for the following reasons:
• Legal Compliance: Adherence to standards such as BS EN 50171 and BS 9999 is mandatory for life safety systems. Failure to comply can lead to legal repercussions, fines and increased liability in case of accidents or injuries.• Occupant Safety: Emergency lighting and lift functionality during evacuation can be life- saving. Any level of malfunction in the emergency system can potentially endanger building occupants and pose a serious threat to life
• Operational Continuity: For commercial buildings, keeping systems like security, alarms, and communication online during outages is critical
• Insurance and Liability: Properly installed CPSS systems reduce risk, can lower insurance premiums and reduce legal exposure
Conclusion
While retrofitting CPSS into existing buildings presents a significant challenge, especially when integrating complex equipment such as passenger lifts and elevators, it is a necessary investment in safety and compliance. With the right engineering expertise, strategic planning and high-quality equipment, these challenges can be turned into long-term assets for any building.
