ENERGY
manage the energy they generate from renewable sources by storing it when generation is high and then releasing it later when power demand increases. Adding a battery allows hospitals to use 100 per cent of the renewable energy they generate to help overcome potential grid constraints and build their own reliable network.
Maintaining critical power Maintaining, optimising, and managing backup power technologies is vital for their ongoing effectiveness and to ensure the system evolves with the changing needs of the hospital. Our business is built on long-term relationships with the estates we support throughout the life cycle of their backup technologies. This is typically 25 years although in many cases it extends far beyond to 30 or 40 years. Long-term operability begins with the initial design, and we design our technologies for longevity with systems including high-performance exhausts and fuel systems. Once installed, our engineers work with the estates team to keep the backup power generators, UPS, and BESS equipment operating efficiently, identify areas where performance can be improved, and ensure power is directed exactly where it is needed. We work closely
with facilities managers to support best-practice test regimes that maximise system longevity and resilience. An ideal testing strategy includes routine weekly tests to check general function alongside more detailed annual load tests. Annual tests involve applying full operational load to verify every part of the technology at full capacity and accurately measure the performance of the fuel and cooling systems. Carrying out tests like these in a live hospital environment relies on close cooperation between clinical and operational teams and often means test programmes are scheduled at weekends and in the early morning and late evening to fall outside the busiest consulting and operating times. As healthcare power networks become more connected and more complicated, with more advanced technologies putting increasing strain on grid power, the need for hospitals to actively manage their energy security and resilience is more important than ever before. A new era of technical innovation, including growth in renewable energy, presents new opportunities for healthcare estates to develop sustainable power strategies that reduce the risks associated with future growth and increased reliance on electricity.
