Energy is typically 8-12% of a Greek cafe's revenue. Simple operational changes (espresso machine standby mode, LED lighting, refrigeration door discipline) and switching suppliers can cut this by 20-30% without capital investment.
What Energy Actually Costs Your Cafe
Before managing energy costs, measure them. Most cafe owners know their monthly electricity bill but do not know what percentage of revenue it represents. Target: energy costs (electricity plus gas) should be under 10% of revenue. Above 12% is a significant drag on profitability. Above 15% usually indicates equipment inefficiency or contract problems.
Calculate your energy cost per coffee served: take your monthly electricity bill, divide by the number of coffees served that month. For a typical Greek cafe serving 200 coffees per day at 0.20 euros per kWh for electricity, energy cost per coffee is approximately 0.10-0.15 euros. If your electricity cost per coffee is over 0.20 euros, you have an efficiency problem worth investigating.
Espresso Machine Energy: The Biggest Consumption Item
A commercial espresso machine (La Marzocca, Victoria Arduino, Sanremo) typically consumes 3-5 kWh while heating up and 1-2 kWh per hour in standby/ready mode. At 12 hours of operation daily, a 2-group machine consumes approximately 15-20 kWh per day - roughly 0.5 euros per hour at current Greek electricity rates (approximately 0.22-0.28 euros/kWh for commercial customers in 2026).
Operational savings on the espresso machine: use the machine's built-in timer to start heating 30 minutes before opening rather than leaving it on overnight. Use sleep mode during slow periods (post-lunch slump). Turn off the steam wand heater when not making milk drinks (relevant for cafes that serve espresso-only during certain periods). These changes cost nothing and save 20-30% of espresso machine energy use.
Refrigeration: Constant Load, Hidden Cost
Refrigerators and display cases run 24 hours, so even small inefficiencies accumulate quickly. The most common energy waste in cafe refrigeration: poor door discipline (doors left open during service rush), dirty condenser coils (reducing efficiency by 20-30%), and temperature settings lower than necessary (most ingredients are safely stored at 3-5°C, but many cafe fridges run at 0-1°C unnecessarily).
Clean condenser coils every 3 months with a brush or compressed air. A clogged condenser forces the compressor to work harder and consumes significantly more electricity. This is a 15-minute maintenance task that can reduce refrigeration energy use by 15-20%.
Display case refrigeration: if your display case runs overnight showing products you are not selling, consider whether 24-hour operation is necessary. Some cafes reduce display case temperature at night (raising it to 5-6°C instead of 2-3°C) or turn off display lighting while maintaining the cooling cycle. This saves display lighting costs (typically 50-100W per cabinet) without food safety compromise.
Lighting: Quick ROI on LED Upgrades
If you are still running halogen or fluorescent lighting in any part of your cafe, an LED upgrade is the highest-ROI energy investment available. LED bulbs use 70-80% less electricity than halogen for the same light output. A cafe with 20 halogen downlights at 50W each runs 1000W of lighting during opening hours. The LED equivalent runs 150-200W. At 12 hours per day and 0.25 euros/kWh, the annual saving is approximately 300 euros. LED replacement cost for 20 bulbs: 100-150 euros. Payback: under 6 months.
Electricity Supplier Comparison in Greece
Since the liberalisation of the Greek electricity market, commercial customers can choose their supplier. DEI (Public Power Corporation) is no longer the only option. Competitors including Heron, Elpedison, NRG, and Watt+Volt offer commercial tariffs. Comparison sites like energycost.gr allow Greek businesses to compare current commercial rates.
Switching suppliers does not change your infrastructure or service reliability (the physical network remains the same; only the billing changes). A switch can save 15-25% on your electricity cost if your current DEI tariff is not optimised. Contact 2-3 suppliers for quotes every 12 months; the market is dynamic and competitive.
