The Garrison Hotel is a family-run business situated within Hillsborough Barracks Sheffield. The Grade II listed building, originally a jail, guardhouse and ammunition store has been sympathetically converted into a modern hotel. ZERON was approached to assess the viability of implementing voltage optimisation to reduce the hotel’s energy consumption and therefore costs.

By analysing electricity bills and carrying out a survey, the hotel’s peak energy consumption, or Maximum Demand (MD) was established. This highlighted that the hotel’s electricity supply was far larger than actually required. So, it made more sense to fit an optimiser that met the hotel’s requirements, rather than simply matching the size of the electricity supply. This approach reduced the cost of the equipment, gave a higher return on investment, and resulted in a payback period of under a year.
