Title: How an atmosphere of excellence elevated Hanley Energy to the world stage
Author: Clive Gilmore, CEO of Hanley Energy - North Virginia USA.
A typical UPS lifetime is generally around ten years, as manufacturers are obliged to supply replacement parts for up to ten years after cessation of manufacture. Therefore, the purchasing of equipment five years before this end date may extend the product’s apparent life to 14 years – after which, capacitors and/or batteries usually require replacing for a second or third time thereby making further investment in aging technology prohibitive.
Surprisingly, replacement batteries can cost 30 to 40% of a brand-new UPS system. The standard five or ten-year design life VRLA type battery will generally require replacing at four or eight years.
Replacing individual faulty battery blocks in strings is not recommended due to the different impedances between old and new and equalisation becomes a problem. Rapid chemical build-up within the new blocks will seriously affect their performance and within weeks they can become significantly ‘aged’; best practice is to replace all batteries at the same time.
Replacement of capacitors, AC and DC, is also a costly exercise and although prices vary depending on the UPS system, can amount to around 5-10% of the cost of a new UPS. Recommended replacement times vary between manufacturer with some advocating changing both at five years. Confirm this with your UPS supplier!
For the reasons above, if your UPS is approaching a point where both batteries and capacitors need replacing, it is worth considering the potential commercial advantages of replacement versus repair. A new system will have a 2-year warranty, advances in technology mean it will be more efficient, making significant savings on running costs on both electricity and reduced cooling requirements.
Over time, your load profile will undoubtedly have changed so it is worth investigating Modular UPS systems which can be right-sized more easily to your actual load: why pay for a large UPS when you don’t need it!? The Modular option can therefore reduce CAPEX as well as OPEX. In addition, the latest generation of Modular systems offer the highest availability and continuity of critical power delivery. For example: CENTIEL’s 4th generation modular UPS CumulusPower has 99.9999999% availability.
In some situations, a brand-new system could offer a far better technical solution at a similar cost to replacement parts. For a mid-range UPS system, say 60 to 200KVA, the remedial battery works may cost around £5-15K plus the cost of the capacitors. Suddenly, the cost of a similar sized replacement becomes attractive. Plus, a new UPS will come with that warranty and lower running costs.
However, often in business, OPEX and CAPEX lie in different cost centres. It might be easier to push through a purchase order for replacement batteries than invest in a new UPS which would offer long-term savings on running costs and provide higher availability. Here a total cost of ownership (TCO) calculation is helpful to assess the savings over the long term following a capital investment.
For example, a legacy 200kVA standalone UPS only using 100kVA of power could be replaced with a 200-kVA frame with two x 50KVA Modules. This right-sizing using UPS modules reduces CAPEX and lowers ongoing maintenance costs too.
In a recent TCO calculation: the energy saved by replacing an oversized, inefficient, UPS paid for a new Modular system within three years! The calculated savings over ten years made the decision a ‘no-brainer’.
Advances in UPS technology can also reduce the cost of future replacement parts. Legacy UPS systems have capacitors soldered on to pcb’s, where in contrast, the latest modular UPSs facilitate simple swapping capability via components mounted on screw in sub-assemblies. CENTIEL has designed CumulusPower so the DC capacitors only require replacement every ten years and AC capacitors every five-six years so can be changed separately to save costs.
When considering this repair/replacement conundrum, consider also how your business may change in the future. Will it grow? Will it always run at its current capacity? A new, truly modular configuration offers “pay as you grow” flexibility. Right-sizing the system initially, minimises CAPEX, while providing the capability to upgrade your system’s capacity with additional Modules.

The lead-acid battery systems used to power UPS systems have been proven over many years. The Valve Regulated Lead Acid (VRLA) blocks we used three decades ago are the same as those used today! However, in the next few years, Lithium ion (Li0ion) is set to revolutionise how we back-up our power protection systems. How fast the take up will be, will depend on how rapidly prices reduce to loevels that make the investment in Li-ion a practical alternative.
Prices are being driving down by the automotive industry and have reduced ten-fold over the past ten years. Perceptions are also changing. In the past, there has been some reticence about small Li-ion applications, however, now with the inclusion of battery monitoring systems they are now regarded as a safe and viable option and are in use in a variety of industries. It is only a matter of time before Li-ion becomes mainstream within datacentres across the world.
Increasingly we are being asked to provide comparative quotes for Lead Acid versus Li-ion batteries for UPS installations. Depending on the customer’s project, we are generally finding the initial cost of buying Li-ion compared with Lead Acid batteries works out at around 2.5 times more expensive. When prices can be reduced to around 1.8 to twice the initial purchase price of Lead Acid, we believe the various benefits and considerations relating to total cost of ownership (TCO) will start outweighing concerns about the initial investment.
One of the main benefits of Li-ion is length of life. Lead Acid batteries last around ten years but are normally replaced every seven or eight years. Li-ion lasts twice that and has a built-in battery monitoring system which regulates the charge and measures impedance in real-time. If a fault occurs, the battery monitoring system alerts your UPS maintenance provider, raising awareness of an issue before the block fails. With Lead Acid you only know there is a battery problem when you need to use it and if it doesn’t work then it’s too late!
As well as lasting much longer, Li-ion batteries require less than half the physical space of the equivalent Lead Acid blocks and are less than 25% of the weight. Commonly, above ground-floor installations can require structural strengthening of the building simply to house the required Lead Acid batteries. Logistically, moving many tonnes of equipment in and out of an upstairs comms room, when batteries need replacing, can also present challenges. For data-centres looking to increase their power density within the same foot print Li-ion promises a practical solution.
Switching to Li-ion could also improve the overall efficiency of the comms room. This is because a further advantage of Li-ion is that it can work at a higher temperature, therefore requiring less-expensive cooling, reducing the amount of overall energy consumed. Most IT systems work better at >25 oC and the UPS technology itself can work well up to 40 oC. By contrast: an industry standard estimate is that for every 10 degrees above 20 oC the operating life of a VRLA battery is halved. With growing concerns about reducing the carbon footprints of datacentres, being able to decrease or even remove the electricity requirement for cooling could become an increasingly attractive and important consideration.
However, the up-take and roll-out of Li-ion across the datacentre industry will not happen overnight. Not all systems are Li-ion ready, but they need to be. Manufacturers of UPS equipment need to ensure their technology is compatible and can ‘talk’ to the Li-ion battery monitoring system. Currently CENTIEL and only a handful of other manufactures offer Li-ion ready UPS.
In addition, understandably, the critical power protection industry tends to be particularly risk averse. The early adopters will be the sector’s innovators. Then how rapidly we see Li-ion in mainstream will likely depend on the experience of these first small installations.
Interestingly, the adoption of Li-ion within UPS systems so far has been greater in developing countries in Africa and the Middle East, where the main power grid is less reliable than in the UK and frequent power problems are more commonplace. In these instances, the UPS and battery systems are required to be cycled several times per day. This greater adoption is primarily due to the higher cycling life of Li-ion: typically, 2,500 power-up and down cycles compared with around 300 for VRLA technology.
Over time we believe, there will be an inevitable shift towards Lithium ion batteries as cost reductions, driven by developments in the automotive industry, flow through to the standby power sectors. Incorporating Li-ion will inevitably reduce the size and weight of UPS systems overall and the longer useful working life of Li-ion will mean fewer costly replacements. All of which will benefit customers with reductions in both CAPEX and OPEX and make Li-ion batteries a winning solution for UPS applications requiring compact, innovative protection.

What is your definition of a Modular UPS? A question that, surprisingly, has several answers! We have all become aquainted with those lovely ‘buzz’ words that are associated with modular systems, words like: flexibilty, availability, scalability, right-sizing, pay-as-you-grow and hot-swap.. etc..etc. However, the term modular itself can mean different things to different people so it is important to check the nature of what is being described as a ‘modular system’ carefully when buying a UPS solution to ensure the essential power of your datacentre is protected at all times.
A single standalone UPS unit that protects a critical load is known as an N system configuration. This is all very well but lacks any resilience in the event that the UPS unit develops a fault or is offline for preventative maintenance. Simply paralleling a second standalone UPS unit of the same rating gives us that resilience and is known as an N+1 configuration. Of course, you can parallel several standalone units together of an individual smaller rating to give the same philospohy, for example if we took this to the extreme we could have 101 x 1KVA UPS units in parallel which would still offer 100KVA N+1 configuration. Obviously this wouldn’t be practical but you get the picture. By using this philosophy it could be described – at the most simple level – as a modular UPS system. However, there does need to be the associated electrical infrastructure –switchgear etc – to be able to add more standalone units.
Another definition of modular is a standalone UPS designed and manufactured in a modular format. The main component parts of rectifier, inverter and static switch are modular. This means if there is a problem with say the recitifier it can be swapped easily. However, if one componentt does fail the whole UPS functionality goes down with it. It may be a modular system but its level of availability will not be reliable.
A better solution is what we term: a true modular UPS. This is where several individual UPS modules are contained within a frame. All the individual modules are UPS’s in their own right, all containing a recifier, inverter and static switch and all operating online in parallel with each other. For example five 60kW UPS modules may typically be contained within a single frame offering a resilient configuration of 240KWs N+1. If required, it takes moments (around 30 seconds) to ‘hot-swap’ a module while the rest of the modules continue to protect the critIcal load. At no point does the system need to be transferred to maintenance bypass and hence on raw mains.
Some other modular systems include the rectifier and inverter within their modules but the static switch is centralised and separate. This offers a potential single point of failure. It may only take a few moments to replace a separate static switch, but, depending on location, getting to the site to replace it may take a maintenance engineer several hours. During that time the system cannot transfer to static bypass. With a true modular system, where the static switch is included in each module, the rest of the modules in the UPS frame continue to protect the load until it can be replaced. This increases the level of availablity dramatically.
Naturally, often cost comes into the decision making process when purchasing a UPS. However, the purpose of a UPS system must be to protect essential power with the highest level of availability. There must be no potential single points of failure. Therefore, it is important to check the configuration and the definition of a modular system carefully before purchasing.
At CENTIEL our design team has been working with data centres for many years at the forefront of technological development. We are the trusted advisors to some of the world’s leading institutions in this field. For this reason, we have developed our pioneering 4th generation true modular UPS system CumulusPower which offers offer industry-leading availability of 99.9999999% (nine, nines), with low total cost of ownership (TCO) through its Maximum Efficiency Management (MEM) and low losses of energy.
