When discussing the cost of maintaining IT infrastructure, we often focus on the price of servers, licenses, or software. Yet it is easy to overlook one of the quietest budget drainers – electricity. More specifically, the energy that is wasted before it even reaches the target equipment. For years, one of the key points where the greatest losses occurred was in uninterruptible power supply systems, or UPS units.
A technological leap in efficiency
A dozen or so years ago, the market standard for UPS systems was an energy efficiency level of around 80-85%. What did that mean in practice? It meant that 15% to 20% of the energy drawn from the grid was irretrievably lost. That energy did not power servers – it was converted into heat, which in turn placed an additional burden on cooling systems.
It was like filling a bucket with water and having every fifth liter spill out through the side. On the scale of a small, in-house server room, this might have gone unnoticed. But in a professional data center, where power demand is measured in hundreds of kilowatts or even megawatts, those losses translated into significant and very real costs.
Today, thanks to technological progress, the situation looks entirely different. Modern, high-end UPS systems, such as those used in Talex Data Center, achieve efficiency levels of 95-98%. This is a massive leap forward, reducing energy losses by as much as tenfold.
What does higher efficiency mean for your business?
This seemingly technical parameter has a very tangible impact on operating costs and the total cost of ownership of IT infrastructure.
First – direct savings on electricity bills. Lower energy losses mean less power must be drawn from the grid. For a 500 kW data center operating around the clock, annual savings can reach tens or even hundreds of thousands of PLN.
Second – a cascading effect in the form of lower cooling costs. Every watt of energy lost in a UPS system is converted into heat. That heat must then be removed by precision air conditioning systems, which themselves consume large amounts of energy. By reducing UPS losses, we also reduce the load on the cooling infrastructure.
Third – a smaller carbon footprint. At a time of growing environmental awareness, energy efficiency is no longer just a matter of cost, but also of responsibility.
How to choose an efficient data center
The energy efficiency of UPS systems is one of those technical details worth asking about when selecting a colocation partner. It is also worth remembering that efficiency depends on the operating point – in other words, the UPS load level. The best providers are able to design their systems in such a way that UPS units always operate within their optimal load range, maximizing efficiency.
Investing in modern power infrastructure is a decision that pays off on many levels. It not only ensures the highest level of operational security, but also delivers measurable and calculable reductions in the cost of running a business.
