Smart energy monitoring and control for bakeries
An all-electric bakery feels every price rise on its ovens, refrigeration and proofing, with no gas to fall back on. We make that energy visible circuit by circuit, automate the controllable loads, and protect your cold chain, with one monitoring and control stack.
Three forces converge on the bakery sector
High prices, all-electric exposure
Commercial electricity in Ireland is among the highest in the EU, and a modern bakery often runs entirely on it, with 80 kW or more of oven capacity alone. There is no gas to soften a price spike, so energy is both a major cost and one of the few a bakery genuinely controls.
Margin squeeze across food
Ingredient, labour and occupancy costs have all risen, while customers resist higher prices on a loaf or a coffee. With most costs fixed or climbing, controllable overheads like energy are where a bakery defends its margin without touching the product or the team.
Concentrated, addressable waste
Because ovens, refrigeration and proofing dominate the bill and run on predictable rhythms, the savings are unusually concentrated and addressable. The SEAI supports that help fund the fix (microgeneration support tapering toward the end of the decade) are most valuable to bakeries that act sooner.
Three pillars: cost, continuity, compliance
Cost & margin
"In an all-electric bakery, the ovens are half the bill, and most of the waste is invisible."
Ovens and proofing are typically 50–60% of an all-electric bakery's energy spend, and the largest losses hide in plain sight: ovens held at temperature with nothing inside, preheating earlier than needed, heat escaping each time a door is opened to check a bake. None of it shows up on a monthly bill, which only ever reports a single number for the whole site.
The levers are well understood once the data is visible. Scheduling discipline and eco-standby trim oven idle time, descending-temperature batch sequencing reduces inter-batch losses, and sub-metering visibility alone is worth around 10% before any control change. Because production starts in the small hours, much of the heaviest load can be shifted into the cheaper night-rate window, moving cost with no change in consumption. A full programme realistically targets 20–30% of total energy cost, recovered from a budget line that would otherwise only rise.
Product quality & continuity
"A failed compressor overnight isn't a maintenance ticket, it's a skip full of spoiled stock."
The same monitoring that cuts cost also protects the product. Stable, verified oven and proofer conditions mean consistent bakes rather than a batch lost to a drifting thermostat, and continuous temperature data on the cold chain protects expensive stock and long fermentations. Anomaly alerts catch a failing fridge compressor, a propped freezer door or an oven creeping off setpoint before they become a ruined batch or a morning of discarded ingredients.
Automated control adds continuity in the other direction too: the climate plant pre-conditions the space so the team walks into the right conditions for dough each morning, instead of a room that drifted out of range overnight because the simplest way to save energy was to switch things off.
Food safety & compliance
"Evidence on a screen, not a clipboard nobody filled in."
Cold-chain temperature control is a food-safety obligation, and today it usually rests on someone remembering to walk round with a checklist. Continuous, time-stamped logging on every fridge, freezer, blast chiller and proofer-retarder turns that into an automatic record, with alerts the moment a unit drifts out of range. It is an evidence trail you can show, rather than a routine you have to swear was followed.
The same data underpins building risk more broadly. Leak sensors in plant areas and under sinks catch a burst or a running tap within minutes rather than on the next water bill, and the bakery is least-watched overnight, exactly when an unnoticed failure does the most damage.
A modular monitoring and control stack
Each capability is independently useful and independently funded. Most bakeries start with per-circuit monitoring and oven optimisation, the dominant load and the fastest payback, then layer on refrigeration assurance, automated control and lighting as savings prove out.
Oven & process sub-metering
A multi-channel current-monitoring hub with CT clamps in the distribution board breaks the bill down circuit by circuit: each oven, every proofer-retarder, the mixers, the refrigeration fleet and the three-phase mains, all on the same hub. In an all-electric bakery the deck ovens alone are typically 50–60% of the entire energy bill, and they are usually the biggest blind spot. Sub-metering turns "the bakery used X kilowatt-hours" into "the bread oven idled at temperature for three hours with nothing in it," which is where the waste actually sits. Visibility alone is associated with around 10% savings before a single control change is made.
Oven optimisation & chamber sensing
Industrial probes inside each oven chamber and door-contact sensors turn raw current data into a picture of how the ovens are really run: preheat timing, idle time, and the heat lost every time a door is opened to check a bake. From there the levers are well understood: trim preheat to the time genuinely needed, enable eco-standby that drops the oven toward zero idle draw and recovers in a few minutes, and sequence batches from the highest temperature downward so residual heat does the work. On the dominant load in the building, even small percentages are real money.
Refrigeration & cold-chain assurance
Walk-in fridges, freezers, blast chillers and proofer-retarders run around the clock, and in a bakery they often sit next to the ovens, where every extra degree of ambient heat makes the compressors work harder. Temperature and humidity sensors plus door contacts on each unit drive both energy and safety: they expose short-cycling and overcooling, flag condensers that need cleaning, and catch doors left open. The same layer logs a continuous, time-stamped cold-chain record and alerts the moment a unit drifts, so a failing compressor is a notification rather than a morning of spoiled stock.
Automated control & climate setback
The handwritten end-of-day list (turn off the coffee, the lights, the back wall, the door heater) depends on a tired person remembering at the end of a long shift. Smart relays and contactors automate it. The over-door heater runs off a door-contact sensor, on only while the doors are open as required and off when they close. The espresso machine drops to eco or off through the overnight hours instead of holding a boiler hot for twelve idle hours. Air conditioning moves onto optimal-start control: the space is pre-conditioned for dough and comfort just before the team arrives, rather than running flat out all night.
Lighting, occupancy & footfall
LED retrofits with occupancy and daylight control in storage, corridors and back-of-house cut lighting energy and stop lights burning in empty rooms. At the café counter, privacy-safe people counting (motion and radar only, no cameras or audio) relates energy and trade to customers served, so you can see the energy cost per cover and tune opening-hours plant to actual footfall rather than habit.
One dashboard: Optim EOS
Everything above feeds the Optim EOS dashboard, hosted in Ireland, with role-scoped views: the head baker sees oven and proofer status and any cold-chain alert, while the owner or manager sees the energy and cost picture across the site. The same data is the food-safety evidence trail and the measured baseline that proves each saving before the next phase of work is committed. One screen for the whole operation, not a drawer of disconnected controllers.
When monitoring proves the case for capital
Oven exhaust heat recovery
Up to around 20% of an oven's energy can leave through the flue as waste heat at 120–300°C. An air-to-water heat-recovery unit captures it for cleaning hot water, proofing or space heating, typically with a two-to-three-year payback. In an all-electric bakery this is especially valuable, because every recovered kilowatt-hour displaces electricity at the full commercial rate. A sub-metered oven baseline sizes the system on real consumption rather than guesswork.
Rooftop solar PV
A bakery's daytime production and café trade align well with solar generation, which supports a high self-consumption rate and strong returns on a coastal Irish roof. Where a bakery qualifies, the SEAI Non-Domestic Microgeneration Grant supports installing capacity, though that grant is tapering toward elimination later this decade, so the window to claim it is closing. The sub-metered baseline sizes the array against real daytime load.
Sector benchmarks and a modelled example
Bakeries are an emerging vertical for monitoring, so the case rests on the mechanism and published sector evidence rather than a roster of named premises. The figures below are sector benchmarks and a modelled illustration, not Optim first-party results. The point of the monitoring is to replace these ranges with your bakery's own measured numbers.
Bakery energy intensity
Industry benchmarks span roughly 47 kWh per tonne of product (efficient, well-run operations) to 262 kWh per tonne (unoptimised), a fivefold spread that shows how much headroom usually exists. Energy per kilogram of product baked is the single most useful KPI to track week to week. Figures are sector benchmarks, not Optim first-party results.
Where the energy goes
In an all-electric bakery, ovens and proofing are typically 50–60% of the bill, refrigeration another 10–15%, and the remainder is spread across mixers, the espresso machine, dishwashing, lighting, hot water and climate plant. Ovens are the dominant, and most addressable, target.
Idle and eco-mode effect
An oven held at temperature with no product can draw 30–40% of its rated power, and manufacturer eco-standby modes have cut idle energy by up to around 55% in factory tests, recovering to baking temperature within a few minutes.
Visibility effect
Sub-metering visibility alone is associated with around a 10% reduction before any control change, the operation simply shows where waste sits and the team acts on it.
Night-rate opportunity
Because production commonly starts in the small hours, much of the heaviest load can sit inside the cheaper night-rate window (commonly around 40% or more below the day rate), shifting cost with no change in the kilowatt-hours consumed.
Illustrative modelled bakery (~€50,000/yr electricity)
Modelled on the benchmarks above, not a first-party result: a Phase-1 deployment of per-circuit monitoring, oven scheduling discipline and automated shutdowns models to roughly €5,000–€7,000/year of avoided waste (about 10–12%), with a simple payback under a year. A full programme through quick-payback capital measures models toward 20–30% (around €10,000–€15,000/year). A bakery's own bills and ESB half-hour data sharpen this either way.
Our four-step process
Free energy audit
A standalone deliverable: the bakery gets a professional audit report regardless of any next step. Where it qualifies, SEAI's €2,000 Support Scheme for Energy Audits voucher can cover the cost, we confirm eligibility upfront before any commitment.
Tailored design and quote
A hardware and software specification matched to your distribution board, your ovens and refrigeration and the priorities the audit surfaces, not a one-size-fits-all kit. Sized for a single bakery or designed to extend to a second site.
Installation around production
Wireless, battery-powered devices retrofit without ductwork or structural work. The team works around your production and trading hours, including early and overnight shifts, so the bakes and the counter keep running.
Continuous monitoring & support
Baseline, then quarterly reviews, optimisation and ongoing upgrades, with the platform, alerts and firmware managed remotely. The data forms the food-safety evidence trail and the measured baseline for the next phase, or the next site.
Where the money may come from
Eligibility for each scheme depends on the business's profile, the project scope and SEAI's current programme rules. We help assess fit and apply where appropriate, and we do not promise grants we cannot deliver.
SEAI Support Scheme for Energy Audits (SSEA)
€2,000 voucher that can cover the cost of the audit where the business qualifies. Eligibility confirmed upfront, the zero-risk starting point.
Accelerated Capital Allowance (ACA)
100% first-year tax write-off on qualifying energy-efficient equipment (Optim EOS is on the SEAI Triple E register), against taxable trading profit, instead of the standard write-down over eight years. A strong cash-flow lever for a tax-paying bakery.
Local Enterprise Office Energy Efficiency Grant
75% of eligible costs, from a minimum of €750 up to a maximum of €10,000, toward energy meters and controls, LED, heat pumps and refrigeration upgrades. Open to small enterprises (1–50 employees) that have first completed a qualifying audit or Green for Business report, where eligible.
SEAI business energy upgrade supports
Capital support routes for controls, building energy management, solar, heat pumps and fabric measures at larger scale. Scope and rates depend on the current scheme rules and the project.
SEAI Non-Domestic Microgeneration Grant
Supports rooftop solar PV. Tapering annually toward elimination later this decade, so the value is highest for bakeries that act sooner.
SEAI EXEED Certified
Supports the engineering and project-management work on larger capital projects such as heat recovery or a refrigeration overhaul.
Managed-service / pay-from-savings
Where a site is suitable, a managed-service structure may let a bakery spread cost against the savings generated rather than funding capital upfront, subject to assessment.
