Voltage optimisation for hotel groups, pubs, and restaurants
Hospitality sites run long hours with a high proportion of refrigeration, kitchen plant, and HVAC. These are voltage-sensitive loads, which means strong, typically fast-payback savings at the supply level.
Typical sites
Hotels, pubs, restaurants, and venues.
Hospitality is a category where voltage optimisation often delivers its best returns. Load is high, continuous, and concentrated in equipment that's particularly sensitive to supply voltage. The commercial case usually lands inside a single operating year on suitable sites.
- Hotel groups (branded and independent)
- Pub chains and gastropub groups
- Restaurant groups and QSR estates
- Conference and events venues
- Spas, leisure clubs, and health clubs
- Student accommodation and serviced apartments
Why voltage optimisation fits
Long hours, kitchen-heavy load, fast payback.
Hospitality sites pay for voltage gap longer than any other sector, not because the saving percentage is higher, but because the load is active almost continuously. A hotel with a 24-hour kitchen, pool plant, guestroom HVAC, and lobby/restaurant lighting is running voltage-sensitive equipment most of the day, most of the year.
Refrigeration alone is usually enough to justify VO on a pub, restaurant, or hotel site. Cold rooms, walk-in freezers, bar bottle coolers, and commercial fridges run continuously and respond directly to supply voltage reduction, both in consumption and in compressor life, which for high-duty refrigeration is a real operational cost.
For multi-site groups, standardising a VO spec across the estate gives you consistent, rolled-up savings and a single M&V methodology. Useful for owner-operator reporting, for franchisee guidance, and for ESG disclosures.
Typical load profile
Equipment that drives the saving.
- Commercial refrigeration and walk-in cold rooms
- Kitchen cookline, ovens, extraction
- HVAC, chillers, and cooling towers
- Pool, spa, and wellness plant
- Laundry operations
- Guestroom and public-area lighting
Install considerations
Low-season and day-part install windows.
For standalone pubs and restaurants, install is typically done mid-morning between service periods with a short planned closure. Most sites are back in trade within the same day.
For hotels and venues, install is phased around low-occupancy periods. A branded group with a seasonal pattern (city hotels midweek, country hotels midweek out-of-season) can schedule the install with minimal revenue impact, and we'll coordinate with the duty manager on the day.
Pool and spa plant is usually the most voltage-sensitive system on a hotel site. Where that plant sits on its own supply (common in leisure-focused properties), we can install a dedicated VO unit there for a cleaner M&V picture.
