Cut Cafe Energy Costs Without Losing Speed
Australian cafe owners face a perfect storm: energy bills are climbing faster than espresso machines heat water, yet slowing down service isn't an option. The good news? You can trim 15–25% off your electricity costs without sacrificing speed or customer experience. Here's how.
Why your cafe's energy bill is higher than it should be
Australian hospitality venues spend between 5–8% of turnover on energy, according to the Australian Hospitality Council. For a cafe turning $800k annually, that's $40–64k per year. A single espresso machine left on standby overnight costs around $50–80 per month. Multiply that across a kitchen full of equipment, and you're bleeding money.
The real culprit? Most cafe owners don't have visibility into when and what is consuming power. A broken fridge seal, an oversized compressor, or a grease-caked hood fan can add 20% to your bill without you noticing.
1. Audit your equipment — the unsexy but crucial first step
You wouldn't order stock blind; don't manage energy blind either.
What to do:
- Call your energy provider (Origin, AGL, EnergyAustralia) and request a detailed consumption breakdown by time of day. Most provide free audits for small businesses.
- Walk your kitchen with a checklist: Is the fridge sealed? Are compressors clean? Is the grease trap on the hood fan clogged? A clogged hood fan can force your HVAC to work 30% harder.
- Hire a tradie or energy auditor ($300–500) to spot quick wins. This usually pays for itself in one month.
Real example: A Melbourne laneway cafe discovered their second fridge (used only for milk overflow on Saturday mornings) was running 24/7. Turning it off except weekends saved $1,200 annually.
2. Retime your peak-load equipment
This is where most owners miss the mark. Energy pricing in Australia is time-sensitive, but few cafes use that to their advantage.
How peak pricing works in your state
Victoria, NSW, South Australia: Peak rates (typically 2–8pm) cost 2–3x more than off-peak (9pm–7am). Queensland and WA have similar structures.
What to do:
- Batch your high-draw tasks off-peak. If you prep stock or deep-clean equipment, do it early morning (6–7am) or late evening (9–10pm) when rates are lowest.
- Preheat your oven during off-peak. If you bake or reheat, start 15 minutes before service using off-peak electricity.
- Check your contract. Some venues are on flat-rate tariffs (not time-of-use). If so, negotiate with your supplier—Bidvest, PFD, or Countrywide can often connect you with better energy deals as part of their broader partnerships.
3. The counter-intuitive tactic: Use your espresso machine as a thermal battery
Most cafes turn off their espresso machine during quiet periods (say, 2–4pm). Don't. Keep it on, but drop the group-head temperature by 2–3°C and reduce boiler pressure slightly. You'll save more energy from preventing repeated heat-up cycles than you'll lose from the lower idle consumption.
Why? Espresso machines use massive energy to heat cold water from ambient temperature. Keeping it warm at a slightly lower set-point uses far less electricity than cycling it off and on. You'll also pull better shots because the machine isn't thermally shocked.
Caveat: This only works if your machine has a PID controller or twin boiler. Older single-boiler machines should still be switched off during dead time.
4. Optimise your refrigeration
Fridges and freezers are often the second-largest energy draw in a cafe (after HVAC). Small changes compound.
Actionable steps:
- Set temperatures correctly. Fridges should be 3–5°C, freezers –18°C. Every degree lower costs 3–5% more energy. Check with a thermometer—many are set colder than needed.
- Clean condenser coils monthly. Dust buildup forces the compressor to work harder. A 15-minute job saves 10–15% of fridge energy.
- Install night blinds or insulated covers. If your fridge is in a high-sunlight area (common in laneway cafes), a reflective cover during closed hours prevents solar heat gain. Cost: $100–200; payback: 3–4 months.
- Group fridges together. If you have two small fridges, consider replacing with one larger unit. Consolidation reduces perimeter surface area and total compressor runtime.
5. Master your HVAC system
Heating, ventilation, and air conditioning accounts for 30–40% of cafe energy use, especially in summer (December–February in Australia).
Quick wins:
- Service your system before summer. A clean filter and balanced airflow can cut HVAC energy by 15%. Many councils (Melbourne City Council, City of Sydney) offer small-business energy rebates that cover servicing.
- Install a programmable thermostat. Set it 1–2°C higher during off-peak hours and lower it 30 minutes before opening. Cost: $150–300; annual saving: $400–800.
- Seal gaps around doors and windows. Cold air leaks are invisible money loss. Use weatherstripping ($20) and check seals quarterly.
- Use ceiling fans. A ceiling fan costs ~$0.02/hour to run but can circulate cool air more efficiently than cranking AC. Install one above your seating area.
6. LED lighting + smart controls
If you haven't switched to LEDs, do it now. LEDs use 75% less energy than halogen and last 10x longer.
Go further:
- Install motion sensors in dry stores and toilets. Lights off after 10 minutes of no movement. Cost: $30–50 per sensor; payback: 2–3 months.
- Use warm-white LEDs (2700K) in customer areas. They're cheaper to run than cool-white and feel more inviting. Neutral white (4000K) in the kitchen for accuracy.
- Dimmer switches in back-of-house. You don't need full brightness during prep; dimmers cut energy without affecting visibility.
7. Negotiate with your supplier
Bidvest, PFD, and Countrywide aren't just food suppliers—they're also energy brokers for hospitality groups. A single call can unlock better rates.
What to ask:
- "Do you have group energy purchasing for hospitality venues?" Many suppliers bundle energy with food ordering to negotiate better rates.
- "Can you review my current contract for hidden fees or better tariffs?" Suppliers often spot opportunities owners miss.
- Time your negotiation. Rates reset quarterly (Jan, Apr, Jul, Oct). Renegotiate before rate hikes.
8. Track and respond to your bill
The biggest mistake? Paying the bill without reading it.
Monthly routine:
- Compare kWh usage month-to-month. A sudden spike signals a problem (broken fridge, faulty equipment, or a tariff change).
- Flag unusual charges. Disconnection fees, supply charges, and demand charges can be disputed if you've been proactive.
- Request a detailed invoice from your energy provider. Most provide breakdowns by time of day.
Where Calso fits in
Managing energy costs requires data—knowing what's running, when, and for how long. Calso's operations platform helps hospitality venues automate routine admin tasks, freeing you to focus on the operational decisions that cut costs. By handling supplier ordering, invoice review, and operational tracking, Calso helps you spot inefficiencies (like that forgotten fridge or oversized equipment) faster. You'll also catch billing errors and anomalies that often hide in energy invoices.

Key takeaways
- Audit first. You can't optimise what you don't measure.
- Retime your loads. Peak pricing means off-peak prep saves real money.
- Keep your espresso machine warm, not hot. A counter-intuitive win most owners miss.
- Maintain your equipment. Clean coils, sealed doors, and correct temperatures compound over months.
- Bundle with your supplier. Bidvest, PFD, and Countrywide often negotiate energy as part of broader deals.
- Track monthly. Spot spikes early and challenge your bill.
Cuts of 15–25% are realistic without service compromise. Most take 3–6 months to implement but pay for themselves within a year.
