Where supermarket power bills actually go
Refrigeration alone is 50–65% of an independent grocer's electricity spend and runs flat 24/7. Brisbane's afternoon ambient peak drives condenser load up exactly when solar is at its strongest — the load-to-solar alignment is genuinely exceptional.
Refrigerated & freezer aisles (24/7)
Multi-deck open dairy/deli cabinets, glass-door freezer aisles, walk-in coolrooms and freezers behind the back wall. Refrigeration alone is 50–65% of total store kWh on most independent grocers and runs flat 24/7, with afternoon condenser-fan ramp matching peak solar generation. Brisbane summer ambient (35°C+) drives condenser load up exactly when solar is at its strongest — the alignment is almost too convenient.
HVAC, dehumidification & door air-curtains
Trading-floor HVAC (typically 40–120 kW on a 1,500–2,500m² store), entry air curtains at automatic doors, anti-condensation heaters around freezer cabinet edges and door frames. Brisbane humidity makes dehumidification a year-round load, not a summer-only one — and humid air falling onto cold dairy/freezer cabinets is the #1 cause of cabinet ice-up and 'foggy door' shopper complaints.
Trading-floor lighting & aisle LEDs
Trading-floor LED bays (typically 200–600 fittings on a mid-size IGA), perimeter feature lighting, signage and pylon sign, cabinet LED strips inside dairy/freezer doors, car park flood and pole lights. Most independents still run a mix of LED conversions and legacy fluoros/metal-halide — we audit and quote an LED retrofit alongside solar where ROI stacks (typically 18-month payback on the lighting alone).
Bakery ovens, deli, butcher, BOH
In-store bakery (rack ovens, proofers, dough mixers — 30–80 kW peak), service deli slicers and hot food bain-maries, butcher band saws and mincers, rotisserie ovens, coffee plant, EFTPOS/POS stack, back-office HVAC and offices. Bakery is the second-largest single load after refrigeration on stores with an in-house bake operation, and the morning-to-midday bake schedule aligns reasonably well with the solar curve.
Why Brisbane independent grocers are going solar in 2026
Four reasons store owners and group sustainability teams across South-East Queensland are signing solar contracts this year — beyond simple bill savings.
55–70% store power bill reduction
A typical 1,800m² suburban Brisbane IGA/Foodworks drops from $215k/yr to $72–95k/yr on a well-sized 150kW solar + 100kWh BESS. Larger 3,000m²+ stores with full bake/deli/butcher routinely save $180–290k/yr on 250–400kW installs. Five years of compounded savings nearly always exceeds the install cost — and unlike GP margin on canned goods (3–6%), the savings are locked in for 25 years independent of foot traffic or competitor pricing wars.
Stock-loss protection via battery + soft-start
A single 6-hour blackout during Brisbane storm season can spoil $35–90k of refrigerated and frozen stock on a mid-size IGA, plus 24–48 hours of recovery trading impact. A 80–200 kWh BESS sized to bridge refrigeration plant + emergency lighting through a typical worst-case outage protects the asset. Equally importantly, our hybrid inverters provide soft-start support for compressor restart after grid events — the cabinet 'pull-down' transient is often what trips the next outage on a marginal feeder.
Metcash, Drakes, SPAR & Foodworks group programs
Metcash (IGA/Friendly Grocer/Foodland), Drakes Supermarkets, SPAR Australia and Foodworks all operate sustainability and energy-cost programs at varying levels of maturity. Independent owner-operators retain capex authority on their own store, but group rebate programs, preferred-supplier panels and green-loan finance are often available — we coordinate with all major group sustainability teams and apply for relevant LGC and demand-response program revenue stacks.
IAWO + STCs + LGCs + accelerated depreciation
Independent grocers under $50M turnover deduct 100% of install cost in year of purchase under IAWO. STCs apply at purchase on systems up to 100kW; LGCs are created annually on systems above 100kW (typically worth $4–9k/yr on a 200kW system at current spot). Battery storage attracts accelerated Div 40 depreciation. Combined, after-tax payback typically lands at 2.8–3.5 years on independent grocers — exceptional in any small-commercial sector.

Don't install supermarket solar without a refrigeration critical-load sub-board
The single most common independent-grocer solar mistake is installing standard grid-tied solar with no critical-load architecture. A 6-hour storm-season blackout can spoil $35–90k of refrigerated and frozen stock plus trigger 24–48 hours of recovery trading impact — and Brisbane storm season delivers multiple feeder outages per year. Insist your installer (1) designs a dedicated refrigeration critical-load sub-board, (2) sizes the battery to bridge worst-case feeder outage of all refrigeration plant (not trading-floor lights/HVAC), and (3) configures seamless islanding with soft-start support for compressor restart. The incremental cost over basic solar is $40–80k and pays for itself the first time a serious storm hits.
