Future trends for UPSs

Kohler Uninterruptible Power News and PR from Kohler Uninterruptible Power - Published 02 November 2017 What does the future hold for UPS technologies and systems? We asked Alan Luscombe, Director at UPSL, for his views, as summarised below.
What does the future hold for UPS technologies and systems? We asked Alan Luscombe, Director at UPSL, for his views, as summarised below.

Currently, the hottest topic is the lithium-ion vs. VRLA lead-acid debate. Li-ion offers several advantages, including lower TCO, longer life, smaller size and weight, and higher operating temperature tolerance. However, although li-ion market share has been growing steadily over the last two-three years, especially as prices have been dropping, VRLA is not expected to disappear soon. The biggest barrier appears to be li-ion’s higher initial cost.

We have seen a steady growth in demand for modular UPS technology over the last two years, especially in higher-power applications. While products below 200 kVA are widely available, there is currently only two competitors for our PowerWave 9000DPA, and our PowerWAVE 9500DPA at 500 kVA is unique for now. However, players are entering the market for 300 kVA and beyond. We are also seeing more Asian products coming onto the UK market.

As winter approaches, we have no tangible evidence of utility power problems – there currently appears to be ‘just enough’ capacity. More nuclear energy capacity will ease the pressure, but this is very slow in developing.

Business forecasting is difficult, with so many unknowns, primarily Brexit. An IHS Research forecast for the UK predicted a negative economic impact from Brexit, but actually the economy has continued to grow. The largest effect has come from the falling pound.

Another trend that will continue after Brexit is the government’s commitment to reducing carbon emissions. Compliance criteria will become ever more stringent, while the Department of Energy and Climate Change’s Enhanced Capital Allowance (ECA) scheme rewards eligible energy-saving equipment with tax breaks. These realities, plus the threat of higher energy costs, are driving the market for higher-efficiency UPSs, with efficiency norms moving from 95% to 96% now, and 97% being forecast.

There is also an increasing demand for UPSs capable of dynamically adjusting their capacity, and especially reducing it to improve efficiency, if the load is unexpectedly low. This facility is useful in converged infrastructure, virtualised data centres, where servers are dynamically allocated – or de-allocated – to match changing software workloads.

Users increasingly expect to see their UPS online as an intelligent network node. Specifically, they want immediate warning of impending problems, enabling rectification before failure. Allowing third-party maintenance organisations to run a predictive maintenance service through 24/7 remote monitoring is particularly important.

UPS intelligence can also aid longer term power system management and optimisation, through load monitoring, regular reports on UPS status, and analysis of trends over time.

  • UPS, heal thyself

    UPSs exist solely to deliver clean, uninterrupted power to their critical load but their ability to do so is entirely bounded by their resilience to failure of their own components or subsystems.

  • Choosing a generator for data centre power protection

    UPS generators are no longer just a backup plan. Today, they are considered a vital component of a companys power protection policy, as sizing UPS batteries for protracted power blackouts is simply uneconomic and impractical. In choosing a generator for a data centre or other critical IT load application, a number of factors must be considered. These include the generators key components, environmental issues and the qualifications of the suppliers as well as compatibility with the UPS to be supported. In this article, Alan Luscombe, director at Uninterruptible Power Supplies Ltd., a Kohler company, discusses how generators work with UPSs, and the factors you must consider when choosing a generator as part of your power protection policy.
