Voltage Optimisation
Ragdale Hall Spa, located in the scenic Leicestershire countryside, has earned a reputation as one of the UK’s premier boutique destination spas.
Operating for over 30 years, the spa combines luxury accommodation with comprehensive wellness offerings, including 93 bedrooms, six pools, and twelve specialised water and heat experiences such as garden saunas, volcanic salt baths, and cave showers.
Challenge
As a high-energy facility, Ragdale Hall Spa relies heavily on electricity to power pools, water heating systems, HVAC, lighting, and other guest amenities. This high consumption, combined with rising and volatile energy prices, creates substantial cost pressures. Additionally, the ongoing operation of electrical systems also contributes to equipment wear and increased maintenance expenses.
At the same time, sustainability has become a central focus for the business. Ragdale Hall is committed to reducing its environmental impact through lowering its energy consumption and carbon emissions, reflecting both regulatory expectations and growing guest awareness of eco-friendly practices. Achieving net-zero emissions has become a strategic priority, aligning with the spa’s wellness and social responsibility values.
Solution
To address these challenges, Ragdale Hall Spa implemented Voltage Optimisation (VO), a dynamic system designed to regulate and stabilise incoming mains voltage. While the UK nominal voltage is 230 volts, electricity delivered from the National Grid often averages around 240 volts, resulting in energy inefficiencies and increased stress on equipment.
By maintaining voltage within an optimal level, Powerstar’s VO systems aim to improve energy efficiency, reduce waste, and extend the lifespan of electrical equipment such as pumps, water heaters, and HVAC systems. For a facility where pools and water features operate continuously, even minor efficiency improvements translate into meaningful cost savings.
Conclusion
Reducing energy consumption strengthens the spa’s net-zero credentials, representing a measurable and proactive step toward sustainability. It also helps mitigate the impact of rising energy costs and minimises the risk of unplanned downtime, ensuring smooth, reliable operations in a facility where service continuity is critical for guest satisfaction. Furthermore, the long-term nature of the Powerstar solution provides a durable, low-maintenance approach to energy efficiency.
In conclusion, Powerstar voltage optimisation has proven to be a high-impact, low-disruption strategy for Ragdale Hall Spa. By lowering energy consumption, reducing carbon emissions, and improving equipment reliability, the solution not only delivers financial savings but also strengthens the spa’s commitment to wellness and sustainability. This case demonstrates how spas can adopt targeted energy-efficiency measures in a world increasingly focused on sustainability and operational resilience.
Result
The installation of Powerstar’s Voltage Optimisation systems has delivered around 9.11% annual energy savings for Ragdale Hall Spa, with weekly savings of 10,700kWh. This reduction in electricity use has had a dual impact: significant financial savings and a tangible reduction in carbon emissions.
By lowering voltage stress on high-energy systems, the spa has also decreased the frequency of maintenance needs and extended the service life of critical equipment. This combination of cost efficiency, equipment longevity, and sustainability aligns directly with the spa’s operational and environmental goals.
