DEWA Electrical Load and Connection Requirements for Commercial Premises in Dubai

DEWA controls the technical approval of your electrical design, the inspection of the installed works, the price of the connection, and the release of supply. The UAE government portal describes DEWA as responsible for the supply of water and electricity to consumers within the emirate of Dubai. DEWA's Getting Electricity Permits & Connections page records that the service "is provided for registered consultants & Contractors", so an occupier appoints an enrolled firm rather than filing the connection application itself. What DEWA does not control is your licence, your Ejari, or your landlord's willingness to cooperate — those sit with other bodies covered across the Licensing & Utilities hub.

The practical consequence is that DEWA is a sequencing dependency rather than a negotiation. Its rules are published, its rates are published, and its service-level times are published. Almost every "DEWA delay" an occupier experiences turns out to be an incomplete submission by an appointed consultant, a snag list from a failed inspection, or a landlord document that was never obtained.

It depends on whether you are energising a whole building or a single unit inside one that already has supply. The two services have different applicants, different document sets and different timelines.

Two things in that table are worth pausing on. First, an occupier cannot file with DEWA itself. The fit-out page describes its service as enabling enrolled contractors and consultants to obtain a power supply connection to a consumer's shell and core or fit-out installation, both pages give the procedure as applying online through the DEWA website, and the FAQ on each answers the question of who can submit with "Enrolled Consultant and Contractor only". Appointing a firm that is not DEWA-enrolled is a self-inflicted delay. Second, for projects licensed under Dubai Municipality, the Building NOC and Getting Electricity applications go through Dubai Municipality's Building Permit System rather than DEWA's own channels, with DEWA receiving the request by digital integration.

The building-level rows have also been converging. DEWA now publishes the whole-building service as "Getting Electricity Permits & Connections" and describes it as enabling enrolled consultants and contractors to request electricity permits and connections through a single application, bundling Building No Objection Certificate – Electricity together with Getting Electricity Connections so that a successful submission returns the approved Building NOC, the design approval and the estimated invoice. Treat that as a change to the filing rather than to the substance: the NOC remains a distinct approval carrying its own two-working-day service level, its own document list and its own expiry clock, and the older DEWA pages describing the two services separately are still the ones most third-party summaries reproduce.

There is a third route in the same DEWA menu, and it is the one most often missed. DEWA's Electricity Network Services list carries "Al Namoos -Getting electricity service" alongside the two above. Its page states that the service "is exclusively for contractors", that DEWA launched it in December 2014 and that it "has been upgraded to provide electricity connections in just two steps within 5 days, for all projects up to 150 kW". DEWA classifies an Al Namoos project by three criteria — permanent and new connections to the premises, load up to 150 kW, and power supply from DEWA's existing network — and describes the procedure as the electrical contractor applying for a low-voltage inspection, after which DEWA carries out the external work, meter installation and final connection once the connection fee is paid, with a stated time to complete of five days. The band is what makes this matter to an occupier: 150 kW covers a large share of single commercial units, and DEWA prices the speed into its own service levels, issuing the connection cost in one working day for an Al Namoos project of 1–150 kW against three working days for all other project types. Because the service is stated to be exclusively for contractors, it is a route your appointed contractor uses on your behalf, not one you file yourself — so ask whether the unit qualifies before assuming the standard timeline.

For a whole-building connection, DEWA's Getting Electricity service requires a project or plot summary of total connected load, MDB and SMDB schedules, a typical load distribution schedule for final distribution boards including load and maximum demand and the number of kWh meters at MDB and SMDB level, a single line diagram of the proposed LV distribution and tariff metering, a site setting layout and ground floor plan showing substation, LV room, meter and MDB locations, dimensional details of the LV or electrical room, a ground floor and/or typical floor plan indicating the location of electrical rooms, MDBs, SMDBs, DBs and kWh meters with installation details, wiring layouts for lighting and power, a layout of drawing, substation details where applicable, a premise details sheet, and the signed "Terms and Conditions for Supply of Electricity – Water" — which must be signed by the owner before supply release. Site photos are required at LV inspection submission.

Because the Building NOC is now filed inside the same application, the NOC's own requirements arrive with it. Two matter more than their length suggests. DEWA asks for an affection plan where the project falls in a Dubai free zone area, which is precisely the case for a large share of the readers of this guide. And it asks for a copy of the setting-out plan, with the meter location indicated where the load is under 400 kW. Above that line the paperwork changes: DEWA's Building NOC requirements add a project details information letter for a proposed load of 400 kW or above — wording that now survives only on DEWA's retired NOC page rather than in the live document list, as the closing section of this guide sets out. The 400 kW figure therefore governs the paperwork as well as the substation question.

The fit-out list is shorter and much more relevant to a typical tenant:

The landlord NOC is the item that most often stalls a tenant. It has to be in DEWA's prescribed format, and a landlord who is slow, absent or in dispute with the tenant can hold up energisation indefinitely. That obligation belongs in the lease, not in a hopeful email later — a point picked up alongside the other pre-signature items in the Licensing + Premises Due Diligence Checklist. The NOC side of the process, including how it interacts with Civil Defence sign-off, is covered in the DEWA and Civil Defence NOCs guide.

Note also the first line of the fit-out list: it presupposes a DEWA-approved total connected load for the main project. If the building's approved load has no headroom left, no amount of tenant paperwork creates capacity.

On total connected load alone, using a published slab unit rate per kW. DEWA introduced the system with effect from 1 January 2017 and then extended it to all projects without any limitation on total connected load. Its own description is that the method "is based on total connected load only, regardless of cables length, route or equipment required for power connection", with the total connected load divided into bands and the applicable rate applied to the load in each band to arrive at a cumulative figure.

Three qualifications sit around that table, and all three come from DEWA's own builder FAQs rather than from anyone's interpretation of them. The slab rates apply to permanent connection loads, with remote and unplanned areas, street lighting and temporary supply for events expressly outside the system. Innovation and knowledge fees totalling AED 20 are charged in addition to the slab rate. And where the applicant chooses to lay the HV cable using its own DEWA-approved contractor, DEWA deducts the cable-laying charges from the slab-rate connection cost as per actuals, regardless of payment. None of these is large enough to change a decision on its own, but a budget that presents the slab figure as the whole cost is not quite the figure DEWA will invoice.

The service itself is free to apply for; the connection cost is invoiced separately once DEWA has approved the load, and the estimate is valid for one year from issuance.

Take a 250 kW showroom-and-workshop unit on a plot that carries no existing approved load. Applying DEWA's published rates on its cumulative band method, the first 170 kW is charged at AED 250 per kW (AED 42,500) and the remaining 80 kW at AED 290 per kW (AED 23,200), for a connection cost of about AED 65,700.

Now push the same unit, still from a standing start, to 450 kW because the occupier adds a spray booth and additional cooling. The first 170 kW is still AED 42,500, the next 230 kW to the 400 kW mark adds AED 66,700, and the final 50 kW at AED 300 per kW adds AED 15,000 — roughly AED 124,200.

The "no existing approved load" qualification is not decoration, and it is the single most common way these numbers get misused. DEWA's builder FAQs state that the slab unit rate connection charge is based on existing and proposed load, that the slab starts based on the existing load, and that only the proposed load is charged. So a tenant adding load inside a building that already carries several hundred kilowatts of approved load does not begin at slab 1 and AED 250 per kW: the addition is priced in the bands sitting above the building's existing load, which for a well-let asset can be several slabs up. The arithmetic above is the right method applied to a bare plot. Applied to a fit-out in an occupied building it understates the cost, sometimes severely. Establish the existing approved load first, then apply the bands.

The instructive part is not the money. Between 400 kW and 401 kW the marginal rate barely moves, from AED 290 to AED 300 per kW. What changes at that point is the substation obligation, which is a floor-area and programme problem rather than a per-kW one. These are illustrations of DEWA's published method, not quotations: the estimate DEWA issues against your approved total connected load is the figure that governs.

Loads of this size are activity-driven rather than area-driven, which is why an F&B unit and an office of identical size can be two slabs apart — see how electrical load needs vary by business activity for the ranges by use class.

Above 400 kW of total connected load. Section 3.1.4 of the 2017 Edition of DEWA's Regulations for Electrical Installations puts it plainly: "In general, where the total connected load exceeds 400 KW, provision shall be made within the building or plot for DEWA's substation. In some circumstances a substation may be required for connected loads less than 400 KW." The requirement is confirmed in DEWA's No Objection Certificate, which is revalidated at the end of a period specified by DEWA.

Read the qualifiers as carefully as the number. "In general" and "may be required" mean 400 kW is the point at which DEWA makes a decision, not a line that guarantees an outcome either side of it. A scheme at 380 kW is a question to put to DEWA, not a clearance. The same threshold shows up in DEWA's service design: its Building NOC requirements call for a project details information letter for proposed loads of 400 kW or above.

For very large developments the obligation goes further. DEWA's Power Supply Guidelines for Major Projects — current at Issue July-2025, Revision-7 — require the project developer to submit an undertaking letter covering the 400 kV and 132 kV substation plots and corridors allocated within the project boundary. Section 3.1.12 sets out what the developer is signing up to: diverting all services within the plot allocated for the 400/132 kV or 132/11 kV substation well in advance of any construction works at site and bearing all the associated costs; giving DEWA unconditional round-the-clock access to the 400 kV and 132 kV corridors for patrolling and maintenance, heavy machinery included; keeping those corridors levelled and free of trees and structures; diverting existing infrastructure services within them at the developer's cost; installing the 132 kV ducts ahead of any cable-laying works; providing access roads built to DEWA standards and wide enough for a lowbed trailer and crane; and reinstating tiles, footpaths, landscaping and shrubs after cable-laying, maintenance or emergency works.

The trigger matters as much as the list. Under Revision-7 the diversion obligation bites in advance of construction works at site rather than at a document stage, and it is separately restated among the submissions DEWA requires before it will issue a Project Parameter Report for a 132/11 kV substation — where DEWA also requires the site to be cleared of all obstacles, services and utility infrastructure, and the access road and gate level to be finalised, before the PPR is issued. Check the issue and revision of any copy of the guidelines quoted at you: the current document is Issue July-2025, Revision-7, and its undertaking covers the 400/132 kV plots and corridors as well as the 132/11 kV substation plot.

For an investor buying into a multi-tenant asset, this is a covenant question as much as an engineering one. If the building's aggregate load is near 400 kW and the letting strategy involves higher-load tenants, someone will eventually have to give up floor area for a substation. Establish who, and at whose cost, before exchange.

More often than not, the constraint is the feeder already serving the unit rather than the network beyond it. DEWA publishes indicative maximum demand limits at the main distribution board for normal residential and commercial premises without large motor loads:

Where the transformer supplies motor or air-conditioning loads with individual motor or compressor loads up to 100 kW, DEWA normally limits the connected load further — to 650 kW on a 1,000 kVA transformer and 950 kW on a 1,500 kVA transformer. Asking a landlord for the feeder rating is a fast, cheap sanity check that a viewing agent can usually answer in a day.

DEWA's rules also require spare capacity to be declared rather than assumed. For multi-consumer installations including shops, showrooms, garages and workshops, the assumed connected load of each spare space or circuit must be indicated in the load distribution schedules submitted for approval. The 1,000 W per socket outlet figure that circulates in fit-out budgets needs its qualifier restored. It appears in the 2017 Edition's clause on 15 A switched socket-outlet circuits, which permits an assumed load of 1,000 W per general-purpose utility socket-outlet in commercial and industrial premises and 500 W per socket-outlet in residential premises. The clause immediately before it governs the 13 A outlets that a conventional office or retail fit-out actually installs, and there DEWA allows a minimum of 200 W per point for general utility purposes other than kitchen, with every twin socket-outlet counted as two separate points. Sizing a 13 A layout off the 15 A figure overstates the load fivefold — an expensive way to talk yourself into a substation conversation you did not need to have, or into paying for connected load you will never draw.

Not for the technical connection, but the final step genuinely is fast. Activation of electricity and water is delivered within 15 working hours of the security deposit being paid, and that service covers business and government customers, not only residential move-ins. DEWA has also integrated the process with the Ejari certificate issuance service from RERA. Its move-in page states that when an Ejari certificate is issued, DEWA automatically receives the necessary customer and property information and "proactively processes the service activation without the need for a separate application", sending a welcome notification carrying the account number, the security deposit details and a payment link. Read the boundary precisely, because that is where the overstatement usually creeps in: DEWA limits the automatic route to leasing contracts under an Ejari certificate and says that in other scenarios — property owners, and customers in free zone areas, which are exempt from Ejari — they will need to apply for the service through DEWA's digital channels. Even on the automatic route nothing is energised until the deposit is paid, because the 15 working hours run from payment rather than from the Ejari certificate.

What does not compress is the design-and-inspection cycle in front of it, and the DEWA windows are only one strand of a wider approvals chain — the fit-out approval timelines and responsibilities guide sets the DEWA clocks alongside the permit and completion-certificate clocks they have to fit around. A Dubai instant trade licence tells you nothing about how long your consultant will take to produce approvable drawings, or how many snags an LV inspection will throw up. The two processes are independent, and treating licence speed as a proxy for occupation date is a common and expensive error — the sort of sequencing detail that also determines whether your Ejari and signage requirements can be satisfied on time.

Ask these before heads of terms harden, not after:

• What is the unit's approved total connected load, and how much of it is unused? The fit-out application requires the main project's DEWA-approved TCL, so this figure exists on paper somewhere. Get it.
• What is the feeder rating serving the unit? Compare it against the indicative maximum demand table above and against the realistic load for your activity.
• Will the landlord commit in the lease to providing an NOC in DEWA's prescribed format, within a defined period? Without it the tenant's fit-out connection cannot be filed.
• Does the intended fit-out push the building's aggregate load past 400 kW? If so, establish who provides the substation space and who bears the cost.
• Is the appointed consultant or contractor DEWA-enrolled? If not, they cannot submit at all.
• When were the Building NOC and any connection cost estimate issued? Both expire, and a lapsed estimate means re-pricing.
• Who pays the connection cost and the security deposit? DEWA fixes the deposit at AED 2,000 for a flat and AED 4,000 for a villa, but for non-residential premises its move-in page says only that the deposit is calculated on the premises' consumption. It sets out no formula and no indicative band there, so this is a figure you cannot derive in advance — allocate it explicitly in the lease instead of assuming it is trivial.

Where the answers point to significant capex — a substation, a supply upgrade, a heavy fit-out — model the effect on net return rather than treating it as a one-off nuisance. The rental yield calculator is a quick way to see what an extra six figures of capex does to a headline yield, and the same discipline applies to the wider licensing and approvals chain where activity-specific regulators impose their own premises conditions.

Capacity risk is not evenly distributed across the market. In an office market where supply is tight, occupiers have less room to walk away from a unit with awkward electrical constraints, and pricing power sits with landlords. In retail, where fit-out intensity is far higher, the load question is usually the binding one long before rent is. Whichever side of the market you are on, the load position should be a documented input to the price, not a discovery made during fit-out.

Note, finally, that everything above is Dubai mainland practice under DEWA. Some free zones and master developments layer their own utility and fit-out approvals on top; the mainland versus free zone comparison sets out where those divergences bite.
