Whether it’s refrigeration that keeps food fresh or inviting aisle lighting that guides shoppers, reliable power is essential. Dr Electric equips grocery stores, markets and supermarkets across the DMV with safe, efficient electrical systems. We handle everything—from cold‑case circuits and prep‑area power to exterior signage and energy‑saving lighting—so you can focus on stocking shelves and serving customers.
Refrigeration is your biggest energy user—refrigeration can consume up to 40 % of a grocery store’s total energy. We design dedicated circuits for reach‑ins, walk‑ins, ice machines and display cases, ensuring proper voltage and surge protection. Balanced panels prevent nuisance trips and downtime. We also coordinate backup power strategies so perishable goods stay cold during outages.
Commercial kitchens and delis need heavy‑duty circuits for ovens, mixers, slicers and warming equipment. NEC Section 210.8(B) requires ground‑fault circuit‑interrupter (GFCI) protection for receptacles in indoor damp or wet locations, including commercial kitchens. Our installations include GFCI‑protected outlets, dedicated branch circuits and code‑compliant spacing around sinks and prep tables.
Lighting not only showcases products—it drives energy costs. ENERGY STAR notes that switching to qualified LED lighting can reduce energy use by up to 90 % compared to incandescent lamps. LEDs also last 35–50 times longer than incandescent bulbs and 2–5 times longer than fluorescents and produce very little heat. We retrofit aisles, produce sections and cold cases with high‑CRI LEDs and install dimmers, daylight harvesting and occupancy sensors to adjust brightness automatically. The result is better visibility, lower cooling load and reduced maintenance.
Your sign is your beacon. NEC Article 600 requires each tenant entrance accessible to pedestrians to have a sign outlet supplied by a dedicated 20‑amp branch circuit, and sign circuits are treated as continuous loads—calculations must use a 125 % factor. A disconnect must open all ungrounded conductors and be within sight of the sign. We install and upgrade sign and canopy lighting circuits, integrate photocells and timers, and ensure your brand shines after dark.
Retail never sleeps. Dr Electric schedules work during night hours or low‑traffic periods, uses dust containment and coordinates with store managers to avoid disrupting customers. From fixture swaps to panel upgrades, our crews are efficient and respectful of your merchandise and staff.
Grocery stores must meet strict safety codes. NFPA 101 requires emergency lighting to provide an average of 1 foot‑candle along exit routes and no less than 0.1 foot‑candle at any point for 90 minutes. Section 210.8(B) demands GFCI protection for receptacles in indoor damp and wet areas, such as prep kitchens and dishwashing stations. Article 600 mandates dedicated sign circuits and disconnects within sight. If your store offers EV charging, Section 625 requires each charger to be connected to its own individual branch circuit. Energy codes require manual lighting controls and at least one dimming step between 30 % and 70 % of full power, with automatic controls that turn lights off within 30 minutes of vacancy. We design systems to meet or exceed these standards and provide documentation for inspectors and utility rebates.
Energy costs account for a significant share of grocery expenses: stores in the US average 52.5 kWh of electricity per square foot annually, and refrigeration and lighting together represent about 65 % of total energy use. Energy costs can reach 15 % of a grocery store’s operating budget, and because profit margins are thin—around 1 %—every dollar saved on energy is equivalent to $59 in increased sales. Upgrading to ENERGY STAR‑qualified LED lighting can slash lighting energy costs by up to 90 %, reduce cooling load and minimize maintenance. Combined with smart controls, these upgrades dramatically cut operating costs. We help you identify rebates and incentives and implement load‑management solutions to avoid costly service upgrades.
