SLASHING ENERGY COSTS WITH LATEST UPS TECHNOLOGY
the council’s critical load was significantly smaller than the existing capacity, with only relatively small increases in load expected over the next five years. This meant a new UPS, specifically tailored to the council’s actual load, could be commissioned. It was at this stage that Uninterruptible Power
Supplies were contacted to provide an efficient UPS system that could manage the transition between the mains and a standby generator, ensuring that all data remained accessible and unaffected by any power interruptions. The selected PowerWAVE 9000DPA system
W
hen West Sussex County Council took over Horsham’s County Hall North building, which
was formally occupied by insurance giant Royal Sun Alliance, a shift in the building’s intended use led to significant changes in its data storage and processing requirement. In turn, this had a knock- on effect on the UPS equipment used to support the critical load and maintain 24/7 availability. Following the council’s arrival, a review of the
current UPS system was commissioned to identify how the changing function of the building had enabled savings to be made. Instrumental in the review process was the council’s Carbon Management Team, which is responsible for meeting targets for reducing energy consumption and carbon emissions across the council’s 300 buildings. Once the review was complete, it was clear that
offered the council a 100kVA load capacity, comprising three 50kVA modules with N+1 redundancy. Should the council’s load require it, the PowerWAVE 9000DPA’s true ‘hot swap’ modularity enables capacity to be added in cost effective incremental steps as power requirements grow. Additionally, the ability to ‘hot swap’ modules whilst the system is online significantly reduces mean time to repair (MTTR) and simplifies system power upgrades. It wasn’t just in cash terms that the council was
able to save. The new system also offered a substantial reduction in carbon emissions, a key driver for the project. “West Sussex’s annual CO2
challenge. That’s why this was such an important project for us. The new UPS system was able to deliver a 37 tonne reduction, due to the UPS being 11% more efficient at its expected loading, so it’s a high proportion of our annual target,” commented Nicola Winser, carbon management officer for the council. West Sussex County Council was also able to

Salix Finance helps to empower public sector organisations to take a lead in tackling climate change by helping to increase their energy efficiency. In the case of West Sussex County Council, only 20% of its own funding was required for the project with the rest coming from Salix matched funding.
