Cost of running mini-fridges and microwaves in empty hotel rooms

The hotel combo that wastes $7.90 per month

Before implementing Revert Smart Plugs, we measured a typical hotel’s mini-fridge and
microwave’s energy usage. We found that in unbooked hotel rooms, this energy-guzzling combo would consume anywhere from 1.7 kWh to 2.1 kWh of electricity per day. The lion's share of usage came from the mini-fridge, which drew anywhere between 60 watts and 90 watts and occasionally peaked to 300 watts during compression.
 

With Revert’s solution, turning this hotel room combo off easily saved 2 kWh of energy per day while the room was unbooked. Even during periods with high room turnover, the combo was kept powered off until the guest shows up at or after 3 pm. As shown in the graph, this resulted in a 65% reduction in energy usage from that 2 kWh baseline to 0.71 kWh in actual usage, realizing 1.29 kWh in energy savings that day. 

Consider a California hotel where the electricity rate can be $0.33 per kWh and the monthly average vacancy rate is 40%. The savings we delivered by turning this room combo off with the Revert Smart Plugs during times the room became vacant were $7.90 per month (2kWh per day x 30 days per month x 40% vacancy x $0.33 per kWh). Annually that's $95 per room.

Each Revert Smart Plug deployed on the hotel combo saves:

  • $95 per year.

    • This is the amount you no longer need to pay the utility company.

It might sound small, but consider a hotel with 100 rooms. Over slow months where vacancy is 60%, the dollar savings can stack up to $1,000 or more. Results may vary depending on your electricity and occupancy rate, so consult a Revert expert to get the most accurate quote.
