Energy and Utility Cost in Restaurants: Small But Real

Utilities are the line item every operator promises they will get to next quarter and never actually does. They are small enough to feel unimportant on any given monthly close and large enough over a year to fund an entire compensation increase for a general manager. Across the 21 Hana Group franchise units I ran, the difference between the best and worst on utility percent of sales was about 1.4 points. That is roughly $500k a year in aggregate. The best units were not spending on efficiency retrofits. They were just running the equipment they had properly.

This is the utility playbook I have used and coached operators through. It costs almost nothing to run, takes about 30 days, and reliably recovers half a point to a full point of margin.

What the utility line actually contains

In most restaurant P&L formats, utilities are a rolled-up line. That is the first problem, because rolled-up numbers hide leaks. Break the line into components before you do anything else:

• Electric: HVAC, refrigeration, lighting, hoods, dishwashers, hot line equipment. Usually 40 to 50 percent of the utility bill.
• Gas: Cooking equipment, hot water, sometimes HVAC. 25 to 35 percent.
• Water and sewer: Dish machine, ice, prep, bar, hand washing. 10 to 15 percent.
• Waste hauling: Front and back dumpster, recycling, sometimes composting. 3 to 6 percent.
• Grease trap service: Depends on volume and local regulation. 1 to 3 percent.
• Pest control, uniforms, linens: Often grouped in the same operating expense bucket. 2 to 4 percent combined.

The 30-day audit that finds the money

Week 1: Pull the bills, chart the trend

Pull 12 months of every utility bill. Chart month over month. Compare to the same month last year. Anything trending up faster than the same-month prior year, controlling for seasonality, is a signal.

What you are looking for:

• A step change in a bill that does not match a step change in sales.
• An auto-renewal rate hike on a contracted service.
• A new fee that appeared and nobody caught.
• A per-unit variance between locations that cannot be explained by size or volume.

On one Hana Group unit inside a Walmart footprint I found the electric bill had climbed 22 percent year-over-year while sales were flat. The reason turned out to be a rooftop condenser fan that was cycling on and off constantly because a temperature sensor had drifted. A $180 sensor replacement dropped the monthly bill back to normal. Nobody had caught it for eight months because the bill got paid by corporate accounting without anyone comparing it to the prior year.

Week 2: Walk every unit at open, mid, and close

Bring a thermometer, a notebook, and a healthy suspicion. What to check:

• HVAC setpoints: Dining room and kitchen. Should be at spec, not five degrees colder because a chef complained one time in 2019.
• Walk-in cooler temperature: 36 to 38 F. Every degree colder is roughly 3 to 5 percent more energy.
• Walk-in freezer temperature: -10 to 0 F. Same math.
• Hot water heater setpoint: 120 F for hand washing per code. Dish machine has its own booster. If the main heater is set to 140, you are heating water twice.
• Exhaust hood run time: When does it turn on, when does it turn off, is it on during hours the line is cold?
• Lighting schedule: Are exterior signs on 24 hours when they should be dusk-to-dawn? Is the dining room lit at 80 percent when a dimmed 60 works fine?
• Standing water use: Any faucet running continuously? Any ice machine dumping constantly? Any bathroom flushometer stuck open?

Nine leaks out of ten are behavior and setpoint. A tenth of what an efficiency retrofit costs, ten times the payback.

Week 3: Fix the free stuff first

Every setpoint that is off spec, correct it. Every schedule that is wrong, reset it. Every piece of equipment running when it does not need to, put on a timer or train the crew to shut it down. This part costs nothing and typically drops the utility bill by 8 to 12 percent within one billing cycle.

Concrete example from Zareen's: three of the five units had their walk-ins set to 33 F because a line cook once complained that produce was "sweating." Fixing back to 37 F dropped combined refrigeration electric by 18 percent across those three units. Roughly $6,400 a year in savings, zero capital.

Week 4: Renegotiate the discretionary contracts

Some utility-adjacent lines are commodity purchases with three or more competitive vendors in every market:

• Waste hauling and recycling
• Grease trap service
• Pest control
• Linen and uniform rental
• Electricity supplier (in deregulated markets)
• Natural gas supplier (in deregulated markets)

Get three bids on each. Include your incumbent as one of the three. Waste hauling is almost always the biggest single line item saving. Typical result across the operators I have worked with:

Waste hauling · 6-unit group audit
  Incumbent contract:      $ 78,400 / year
  Best competitive bid:    $ 59,200 / year
  Savings:                 $ 19,200 / year (24%)
  Bid process time:        ~ 6 hours

Grease trap service
  Incumbent contract:      $ 14,800 / year
  Best competitive bid:    $ 11,600 / year
  Savings:                 $  3,200 / year (22%)

Six hours of work, $22k a year in savings, recurring for the life of the contract. This is the single highest hourly-return operator activity I know of, and almost no one runs it because it is unglamorous.

The equipment upgrades worth running

After the free wins are locked in, the small capital projects are worth ranking. The ones that reliably pay back:

• LED lighting retrofit: 12 to 18 month payback in dining rooms and kitchens. Utility rebates commonly cut that in half. LED also runs cooler, which reduces HVAC load in summer.
• Variable-speed exhaust hood controls: 12 to 24 month payback. The hood senses cook load and modulates fan speed, reducing conditioned air lost to the outside.
• Low-flow pre-rinse spray valves: Under 6 month payback. Cuts hot water use in the dish pit by 40 to 60 percent.
• Smart thermostats / building management: 18 to 36 month payback depending on unit size. Bigger impact in multi-unit portfolios where you can monitor centrally.
• Insulation on hot water and steam lines: 6 to 12 month payback. Trivially cheap. Almost never done.

Check with the local utility for rebate programs before starting any project. In most markets there are commercial efficiency rebates that fund 20 to 50 percent of qualifying equipment. Ignoring them is leaving free money on the table.

The multi-unit view nobody builds

Single-unit utility management is worth doing. Multi-unit utility management, done with a real cross-unit comparison, is where the money actually lives. In a group of five to twenty units running the same concept, the variance in utility percent of sales between best and worst is almost always 1 to 2 points. That variance is not weather. It is not equipment age. It is operating behavior, and it is fixable by pointing at it.

Build a single sheet, updated monthly:

• One row per unit.
• Columns: electric $, gas $, water $, waste $, total utility $, sales $, utility % of sales.
• Sort by utility % of sales.
• Send it to every general manager once a month.

Within 90 days the bottom-quartile units will move up. Not because you did anything. Because they saw the rank. The top-quartile units keep their number honest because they know their peers are watching. This is peer accountability doing the work that hierarchical accountability struggles to do.

On a Hana Group cross-unit comparison I ran, the worst unit was at 5.1 percent utilities-to-sales, the best at 3.4. One point seven points across 21 units on average $1.7M revenue is roughly $600k in aggregate. After nine months of monthly ranking, no capital work, the worst unit was at 4.2 and the group average had dropped 0.6 points. Real money, from a spreadsheet.

The gotcha with sub-metering

One caution. If your unit is inside a larger footprint like a Walmart or Target, you may not have a dedicated utility meter. Cost is pro-rated by square footage or estimated by the host. This introduces two problems: your bill does not reflect your actual consumption, and you have limited ability to argue if it looks high.

Two moves that help. First, ask the host retailer for the sub-metering data if they have it. Some do, some do not. Second, benchmark your utility percent of sales against peer units in the same host format, not against standalone units. Standalone unit benchmarks will always look better because they control their own energy load. An apples-to-apples comparison inside the host format is the fair frame.

Making general managers care

The reason utilities do not get managed is that they are not visible. Fix visibility and the small daily behaviors change on their own.

What to do:

1. Put utility cost as a percent of sales on the weekly flash report. One number.
2. Benchmark against peer units in the group. Rank order weekly.
3. Include the number in the weekly P&L review with the general manager.
4. Set a target improvement, tied to the annual bonus if you have one.

Within one quarter, general managers start noticing lights left on and hoods running past close. Not because you nagged them. Because the number is on their sheet now and they hate being at the bottom of the ranking.

What I got wrong

Early on I chased the capital projects first. LED retrofit, hood controls, a smart thermostat rollout. All good projects, all with real payback. But I burned two months of runway on capital planning while the free wins were sitting untouched. Walk-ins set five degrees below spec, waste hauling on a 2018 rate that had crept 18 percent, an exterior sign left on 24 hours because the timer had failed and nobody noticed.

The lesson: audit and fix the free stuff first. Every hour spent on setpoints and contract renegotiation returns more than every hour spent on capital equipment. Do capital in month three, not month one.

The point

Utilities will not make or break a restaurant. But over a year, in aggregate, across a portfolio, they are a real half point to full point of contribution margin sitting on the floor. Nobody picks it up because it is not glamorous.

Run the audit once. Put the number on the flash report. Rebid the discretionary contracts. Fix the setpoints. Total time investment maybe 40 hours. Total return on a five-unit group typically $50k to $100k a year, forever. That is one of the best trades in field operations.

And one last thing worth saying out loud. Utility discipline is also a culture signal. The unit that pays attention to whether the exhaust hood is running past close is almost always the unit that pays attention to portioning, to comp discipline, to schedule accuracy. Small habits scale. When a general manager starts caring about the electric bill, they usually start caring about three other things a week later, and the whole P&L moves. Not because the electric bill is the leak. Because the habit of looking is the fix.
