Electricity is the backbone of every commercial kitchen in the UAE. Combi ovens draw tens of kilowatts, dishwashers cycle continuously, and refrigeration never stops — all against summer ambient temperatures that stress cables and equipment. Getting the electrical design right from the start determines whether your restaurant operates smoothly or faces costly shutdowns. This guide covers restaurant electrical requirements in the UAE from load estimation and authority approval to distribution boards, three-phase power, emergency generators, energy efficiency, and Civil Defence compliance. For the full MEP picture, see our restaurant MEP engineering service.
Why Electrical Planning Is Critical for UAE Restaurant Fit-Outs
Regulatory authorities — DEWA in Dubai, SEWA in Sharjah, ADDC in Abu Dhabi, and EtihadWE across the Northern Emirates — all require approved drawings and inspections before power can be connected. Under-sizing the supply at fit-out stage means expensive upgrade applications later, while over-sizing wastes capital. A structured electrical strategy, developed in parallel with HVAC design and kitchen layout, avoids both extremes.
How to Calculate Electrical Load for a UAE Commercial Kitchen
Commercial kitchen load calculation in the UAE requires summing individual equipment ratings, applying a diversity factor, then adding HVAC, lighting, and back-of-house loads to reach a total connected demand that informs the authority power application.
Start by listing every piece of equipment with its voltage, phase, and kilowatt rating. Typical loads for a UAE commercial kitchen include:
| Equipment |
Typical Load (kW) |
Phase |
| Combi oven (10-tray) | 18–22 | Three-phase |
| Pass-through dishwasher | 18–22 | Three-phase |
| Induction hob (4-zone) | 12–16 | Three-phase |
| Dishwasher booster heater | 9–18 | Single or three-phase |
| Walk-in chiller (3×4 m) | 2.5–5 | Single or three-phase |
| Walk-in freezer (3×4 m) | 4–7.5 | Three-phase |
| Blast chiller (5-tray) | 3.5–5 | Three-phase |
| Canopy extraction fan | 1.5–5.5 | Single or three-phase |
| Undercounter dishwasher | 6–9 | Single-phase |
Once the equipment list is complete, apply a diversity (demand) factor. Because not every appliance operates at full load simultaneously, UAE MEP engineers typically apply a factor of 0.65 to 0.75 across the kitchen load. A mid-size restaurant serving 150–200 covers typically reaches a total installed kitchen capacity of 135–260 kW before the diversity factor. As a planning benchmark, allow 0.7–1.5 kW of installed electrical capacity per cover when equipment selections are still being finalised.
Add to this the HVAC electrical load (compressors, air handling units, fan coil units), general lighting, small power, POS systems, water heating, and any outdoor signage. The result is your total maximum demand figure, which forms the basis of the power application to DEWA, SEWA, or the relevant authority.
DEWA Power Connection and Approval Process for Restaurants in Dubai
Every restaurant fit-out in Dubai requires DEWA approval before work begins and a final inspection before the supply is activated. The process typically takes one to three weeks for a medium commercial project and follows seven defined stages.
- Drawing Preparation: A DEWA-registered MEP consultant prepares electrical and water layouts to DEWA’s technical standards, including an electrical load schedule stamped by the consultant.
- Application Submission: Documents are submitted through the DEWA online portal or the Dubai Building Permit System. Required documents include an Emirates ID or trade licence, Ejari or title deed, approved MEP drawings, an electrical load schedule, a landlord NOC where applicable, and the Dubai Municipality building permit.
- DEWA Review: DEWA examines the submission and may request drawing revisions. Incorrect load calculations or non-registered contractors are among the most common rejection reasons.
- Design Approval (NOC): Once satisfied, DEWA issues a design approval. This stage takes up to seven working days for straightforward applications.
- Site Installation: Electrical works proceed strictly per the approved drawings. Any deviation triggers a re-approval cycle.
- DEWA Inspection: A DEWA inspector attends site to verify that the installed work matches approved documents, including load calculations, circuit protection, earthing, and cable routing.
- Connection Activation: Upon inspection sign-off and payment of a security deposit (typically AED 2,000–4,000 or more for commercial projects), DEWA installs the meter and activates the supply within 24–48 hours.
In Sharjah, SEWA follows a broadly similar process — SEWA connected power to 3,508 projects in 2025. In Abu Dhabi, ADDC governs approvals under the Abu Dhabi DoE Electricity Wiring Regulations 2020 (based on IEC 60364). Across all authorities, only registered contractors and consultants may prepare and submit technical drawings.
Distribution Boards and Circuit Design for Commercial Kitchens
A well-designed distribution board (DB) for a UAE restaurant separates the kitchen load from dining, HVAC, and general circuits, with dedicated breakers for every major piece of equipment and spare capacity for future additions. Best practice includes:
- Separate kitchen sub-distribution board: Isolate high-load kitchen circuits from dining-area circuits to limit fault impact and simplify maintenance.
- Dedicated circuits for heavy equipment: Each combi oven, dishwasher, and induction suite requires its own breaker. A 10-tray combi oven requires a 32A three-phase breaker with a minimum 6 mm² cable; an induction hob suite typically requires a 25A three-phase breaker.
- RCD protection on all kitchen circuits: All authorities require residual current devices on kitchen and wet-area circuits. Type A RCDs cover the harmonic-heavy loads produced by variable-speed drives in refrigeration and extraction equipment.
- Spare breaker capacity: Build in at least 20–25% spare breaker positions from day one to absorb equipment additions without a board replacement.
- IP-rated enclosures: Kitchen environments are humid and subject to wash-down; distribution boards inside or adjacent to the kitchen must carry an appropriate IP rating (typically IP54 or higher).
- Clear circuit labelling: All UAE authorities require clear circuit schedules on every DB, with danger notices and voltage warning labels.
- Cable derating for UAE ambient temperatures: Outdoor and roof-level runs can exceed 50 °C, reducing rated current capacity. Cable sizing must apply IEC 60364 or BS 7671 ambient correction factors.
The kitchen layout directly affects how DB circuits are grouped. See our guide to commercial kitchen layout types in the UAE for how zone-based designs simplify electrical circuit planning.
Three-Phase Power Supply for UAE Restaurants
Most UAE commercial kitchens require a three-phase 380/400V supply at 50 Hz because combi ovens, commercial dishwashers, walk-in refrigeration, and large induction suites all demand three-phase power. Single-phase 230V supply is adequate only for very small cafés under approximately 40 covers with minimal cooking equipment.
When applying to DEWA or SEWA, the load schedule must specify demand in kVA (not just kW), because the authority sizes the incoming service on apparent power. A typical commercial kitchen power factor is 0.8–0.85. Identifying early whether the building’s existing supply is sufficient — or whether a new transformer is needed — avoids programme delays during fit-out.
Emergency Power and Generator Requirements
UAE regulations do not universally mandate standby generators for restaurants, but a power interruption in Dubai’s summer heat threatens food safety and revenue within minutes. For any restaurant with walk-in refrigeration, a generator is sound investment and, in certain building types, a Civil Defence requirement for life-safety systems.
Recommended generator sizing by restaurant type:
- Small café (30–40 seats): 40–60 kVA
- Mid-sized restaurant (around 100 seats): 80–120 kVA
- Large restaurant or banquet hall: 150–250 kVA
Add a 20–25% buffer above calculated load to handle compressor start-up surges. Key UAE installation requirements:
- Automatic Transfer Switch (ATS): Transfers load from mains to generator within seconds, protecting refrigeration and POS systems.
- Acoustic canopy: Silent-type generators with acoustic enclosures reduce noise by up to 75% — essential in Dubai and Abu Dhabi urban locations with strict noise limits.
- Fuel storage: Diesel stored in clean, ventilated, fire-rated rooms; replace fuel every 6–12 months. Civil Defence sets construction standards for fuel storage areas.
- Fire pump priority: Where a generator serves building fire pumps, the fire pump load is sized first; the generator must sustain a minimum eight hours at full load.
- DCD documentation: Generator installations require fuel storage layout and ATS details as part of the Civil Defence fit-out submission in Dubai.
Electrical Safety, Certified Contractors, and Civil Defence Compliance
Dubai Civil Defence approval is a legal requirement for every commercial restaurant fit-out, covering electrical safety systems alongside fire suppression, detection, and compartmentation. All electrical and fire safety installation work must be carried out by DCD-approved contractors. Key compliance requirements are:
- DEWA-registered consultant and contractor: Only DEWA-registered professionals may design and execute electrical works in Dubai. Using an unregistered contractor results in rejection and potential penalties.
- Electrical installation certificate: DEWA issues a compliance certificate upon passing final inspection. This certificate is required before the municipality issues a food licence.
- RCD testing: Type A and Type AC RCDs must be tested every six months in occupied buildings per Abu Dhabi DoE regulations, and equivalent maintenance obligations apply in Dubai.
- Earthing and bonding: TN-S earthing systems are standard in new UAE commercial installations. Kitchens require supplementary bonding of all metallic pipework, ductwork, and equipment frames.
- Kitchen hood electrical integration: The wet chemical suppression system must be electrically interlocked with the gas solenoid valve and extraction fan — coordination between the MEP contractor and the DCD-approved fire contractor is mandatory.
- Hassantuk connection: Dubai Civil Defence mandates Hassantuk 24/7 monitoring for commercial fire alarm systems, requiring dedicated data cabling and power supply.
- IEC and BS 7671 standards: DEWA mandates compliance with IEC standards and BS 7671 for all wiring, switches, sockets, breakers, and enclosures.
Electrical safety planning runs in parallel with restaurant lighting design; for the lighting-specific compliance considerations, see our restaurant lighting design guide.
Energy Efficiency and DEWA Tariff Management
With DEWA rates reaching AED 0.38/kWh plus AED 0.06/kWh fuel surcharge at the highest tier, energy efficiency measures built into the electrical design reduce running costs from day one.
Current UAE commercial electricity tariffs:
| Authority |
Rate Structure |
Peak Rate (kWh) |
| DEWA (Dubai) | Tiered (4 slabs) + fuel surcharge | AED 0.38 + 0.06 |
| SEWA (Sharjah) | Tiered (mirrors DEWA) + fuel surcharge | AED 0.38 + 0.06 |
| ADDC (Abu Dhabi) | Flat commercial rate | AED 0.20 |
| EtihadWE (Northern Emirates) | Flat commercial rate | AED 0.21 |
Practical efficiency measures for UAE restaurant electrical design:
- Induction cooking: Induction hobs convert 85–90% of input energy to heat versus 40–55% for traditional electric hobs, reducing kitchen load and HVAC cooling demand simultaneously.
- Variable-speed drives (VSD) on extraction fans: VSDs let extraction motor speed track cooking activity, cutting fan energy by 30–50% versus fixed-speed operation.
- T3/T4-rated refrigeration: UAE ambient conditions demand T3-rated units (up to 43 °C) or T4-rated units (up to 55 °C for plant rooms). Under-rated units run inefficiently and fail prematurely.
- LED lighting: LED fittings with occupancy sensors in storerooms reduce base load. See our restaurant lighting design guide for specification details.
- Shams Dubai solar net metering: DEWA’s Shams Dubai programme allows rooftop solar PV with net metering to offset high-tier consumption — viable for ground-floor or rooftop restaurants.
- Power factor correction: Capacitor banks on motor-heavy loads (refrigeration, extraction) improve power factor from 0.75–0.85 toward unity, reducing reactive power charges on larger connections.
Reducing electrical heat gain from cooking equipment also lowers HVAC demand. Our restaurant HVAC design guide covers how kitchen exhaust and make-up air interact with the electrical load.

FAQ
How much electrical power does a typical UAE restaurant need?
A mid-size restaurant serving 100–150 covers typically requires 100–180 kW after diversity factor, translating to roughly 150–250 kVA on a three-phase service. Small cafés under 40 covers may manage on 40–60 kVA; large banquet operations can exceed 300 kVA. The precise figure must be confirmed through a formal load calculation by a DEWA-registered engineer before submitting the power connection application.
Is three-phase power mandatory for a UAE restaurant?
Three-phase 380/400V at 50 Hz is effectively mandatory for any UAE restaurant with a commercial kitchen. Combi ovens, dishwashers, walk-in refrigeration, and induction suites all require three-phase supply. Single-phase 230V is only sufficient for very small grab-and-go operations. DEWA, SEWA, and ADDC size the incoming service based on the load schedule submitted with the approval application.
How long does DEWA approval take for a restaurant fit-out in Dubai?
For a medium commercial project such as a restaurant, DEWA approval typically takes one to three weeks from submission of complete, compliant documentation. DEWA issues the design NOC within up to seven working days once drawings are accepted. Delays occur when drawings do not meet current DEWA standards, load calculations are incorrect, documentation is incomplete, or the contractor is not DEWA-registered. After the installation passes the DEWA site inspection, the power connection is activated within 24–48 hours following payment of the security deposit.
Do UAE restaurants need a backup generator?
UAE regulations do not universally mandate standby generators for all restaurants, but generators are strongly recommended and, in certain building types, required by Dubai Civil Defence to serve life-safety systems including fire pumps. For any restaurant with walk-in refrigeration, a power outage of more than two hours can compromise food safety. A properly sized standby generator (80–120 kVA for a 100-seat restaurant) with an automatic transfer switch maintains refrigeration, lighting, and POS systems seamlessly. Generator installations in Dubai require documentation as part of the DCD fit-out approval submission.
