A smarter approach to resilient, sustainable power for water and wastewater treatment sites.

The UK water sector is in the AMP8 regulatory period with an increased focus on resilience, environmental performance and operational efficiency. As water companies invest in modernising infrastructure, reliable power has become more critical than ever.

To help address these challenges, Dale Power Solutions has developed an innovative hybrid power solution that combines Uninterruptible Power Supply (UPS) and Battery Energy Storage System (BESS) technologies into a seamless backup power solution.

Designed specifically for water and wastewater treatment sites, the hybrid system provides continuous power quality, uninterrupted backup power during mains failures, and intelligent energy storage to support sustainability and reduce energy costs.

Key features at a glance

The table below summarises the key features and benefits of Dale’s hybrid UPS and BESS solution for the water sector.

Why power resilience matters

Power interruptions at water and wastewater treatment sites affect far more than electrical equipment.

A loss of mains supply can stop critical treatment processes, interrupt customer water supplies and require control systems to be restarted and reconfigured before operations resume. At wastewater treatment facilities, prolonged outages can also increase the risk of environmental pollution incidents, regulatory penalties and reputational damage.

Dale Power Solutions is already supporting water utilities with resilient critical power infrastructure. On a recent water treatment project, we designed and supplied a tailored UPS solution using our HE Series, comprising three 80kVA and one 120kVA UPS systems, providing up to 6 minutes of battery autonomy at full load to maintain continuous operation during mains interruptions.

Building on this expertise, Dale has also secured a new Battery Energy Storage System (BESS) project for a water sector pumping station. The 60kW / 200kWh solution will provide secure backup power while enabling intelligent energy management, helping the customer manage an annual electricity consumption of more than 29,000kWh.

While these projects demonstrate the value of UPS and BESS technologies individually, combining them into a single hybrid solution enables water utilities to benefit from both seamless power protection and intelligent energy management within one integrated system.

To discuss these challenges and the thinking behind Dale’s new hybrid solution, we spoke with Stuart McPhail, Head of Commercial UPS at Dale Power Solutions.

Q&A with Stuart McPhail

Why is power resilience so important for water and wastewater treatment sites?

Power failure can have a catastrophic impact on water and wastewater operations. As well as delays restoring clean water supplies and the inconvenience this causes customers, there is a serious risk of pollution events at wastewater treatment plants if critical processes lose power. That can lead to environmental harm, regulatory fines and significant reputational damage.

How does Dale’s hybrid solution address these challenges?

Our hybrid solution combines UPS and Battery Energy Storage System (BESS) technologies to provide seamless backup power while also improving power stability and quality during normal operation. The UPS protects against power disturbances and bridges any interruption, while the BESS provides longer-duration backup power and additional energy management benefits. Together, they deliver a resilient business continuity solution that helps water utilities protect critical infrastructure, improve operational resilience and support their wider sustainability goals.

How the hybrid power solution works

Continuous Power Quality with UPS

The UPS continuously conditions incoming mains electricity before it reaches critical equipment. This protects the site from voltage dips, surges, spikes and brownouts while delivering a constant, high-quality power supply.

During a mains failure, the UPS instantly bridges the interruption, so equipment remains operational without rebooting or resetting. For water treatment sites, this means control panels, drives and motors can continue operating without lengthy recovery procedures.

To withstand demanding environments, the UPS is housed within a purpose-built IP54-rated enclosure.

Intelligent Energy Storage with BESS

The Battery Energy Storage System stores electricity from both the grid and renewable sources before releasing it when required.

In normal operation, this allows water companies to:

• Store renewable energy from solar PV and wind
• Shift energy usage away from peak tariff periods
• Reduce electricity costs
• Lower carbon emissions
• Improve overall site energy efficiency

If a mains failure occurs, the BESS assumes the electrical load soon after the UPS bridge, providing extended backup power while intelligently managing site loads.

Supporting AMP8 objectives

Water companies face increasing pressure to improve resilience while reducing operational costs and carbon emissions.

By combining UPS and BESS technologies, Dale’s hybrid solution helps support several AMP8 priorities, including:

• Improved operational resilience
• Enhanced environmental performance
• Better energy efficiency
• Reduced carbon emissions
• Improved business continuity
• Increased network reliability
