UAE free zones — JAFZA, DAFZA, DMCC, ADGM, KIZAD, twofour54, and others — house thousands of commercial and industrial facilities with large roof areas and high daytime electricity consumption. Federal Decree-Law No. 17 of 2022 explicitly includes free zones in the distributed renewable energy framework, meaning solar installations are permitted. However, the approval process is not handled by the free zone authority. The relevant emirate-level utility — DEWA for Dubai free zones, ADDC for Abu Dhabi free zones — still governs grid connection, metering, and net metering. Free zone authorities may add their own structural, tenancy, and building-code conditions on top. This guide explains the dual-layer approval process and what free zone tenants and landlords need to know. For the full UAE regulatory picture, see the UAE solar compliance hub.
Free Zone Authority Does Not Issue Solar Grid Approvals
A common misconception is that free zones operate their own solar programs independent of DEWA or ADDC. They do not. The free zone authority manages land, tenancy, and building regulations within the zone. Grid connection, metering, and net metering are handled by the emirate-level utility exactly as they are for mainland premises. Do not approach your free zone authority expecting a solar NOC or connection agreement — they will direct you to DEWA or ADDC.
Which Utility Applies to Which Free Zone?
The determining factor is the emirate, not the free zone status.
| Free Zone | Emirate | Utility | Solar Program |
|---|---|---|---|
| JAFZA (Jebel Ali Free Zone) | Dubai | DEWA | Shams Dubai |
| DAFZA (Dubai Airport Free Zone) | Dubai | DEWA | Shams Dubai |
| DMCC (Dubai Multi Commodities Centre) | Dubai | DEWA | Shams Dubai |
| DTEC (Dubai Technology Entrepreneur Campus) | Dubai | DEWA | Shams Dubai |
| DSO (Dubai Silicon Oasis) | Dubai | DEWA | Shams Dubai |
| Dubai Airport Free Zone | Dubai | DEWA | Shams Dubai |
| ADGM (Abu Dhabi Global Market) | Abu Dhabi | ADDC | Energy Netting |
| KIZAD (Khalifa Industrial Zone) | Abu Dhabi | ADDC | Energy Netting |
| twofour54 | Abu Dhabi | ADDC | Energy Netting |
| Masdar City Free Zone | Abu Dhabi | ADDC | Energy Netting |
| RAKEZ (Ras Al Khaimah) | Ras Al Khaimah | EtihadWE | DSS program |
| HFZA (Hamriyah Free Zone) | Sharjah | SEWA | SEWA solar policy |
Free zones in the Northern Emirates (RAKEZ, HFZA) fall under EtihadWE or SEWA, respectively. The same principle applies: the emirate-level utility handles grid connection; the free zone authority handles land and building matters.
The Dual-Layer Approval Process
Every free zone solar project must clear two layers: the utility layer (same as mainland) and the free zone authority layer (additional).
Layer 1: Utility Approval (Mandatory)
This layer is identical to mainland premises. For Dubai free zones:
- DEWA Shams Dubai 4-stage process: NOC → design approval → installation → inspection/connection
- DEWA-approved contractor (Category A/B/C based on system size)
- DEWA-approved equipment via Hab Reeh
- Maximum 1 MW per plot
- No ground-mounted systems
For Abu Dhabi free zones:
- RSB approval before installation
- ADDC-approved consultant and integrator
- ADDC PV Connection Agreement
- Maximum 5 MW per premises
- Energy netting (kWh credits, no cash)
For the full utility process, see the DEWA Shams Dubai guide or the ADDC solar guide.
Layer 2: Free Zone Authority Clearance (Variable)
Free zone authorities do not duplicate utility approvals, but they may impose additional conditions:
| Requirement | Typical Free Zone | Purpose |
|---|---|---|
| Structural approval for rooftop loading | JAFZA, KIZAD, DMCC | Confirms building can support panel weight and wind loads |
| Tenancy contract amendment for energy infrastructure | ADGM, DAFZA | Updates lease to reflect solar equipment ownership and maintenance obligations |
| Building management approval (multi-tenant facilities) | DMCC, DTEC | Coordinates access, shared roof rights, and disruption scheduling |
| Free zone building code compliance | All free zones | Ensures installation meets zone-specific structural and fire safety standards |
| Façade alteration permit | DAFZA, ADGM | Required if panels are mounted on building exterior walls |
| Carport / shade structure approval | JAFZA, KIZAD | Required for structure-integrated installations in parking areas |
The specific requirements vary by free zone and by building type. A single-tenant warehouse in JAFZA faces fewer free zone conditions than a multi-tenant office tower in DMCC. Contact your free zone’s facilities or engineering department at the project concept stage to obtain the current checklist.
Start with the Free Zone Authority, Then the Utility
The practical sequence is: (1) confirm free zone authority requirements and obtain any needed structural or tenancy clearances, (2) engage a utility-approved contractor, (3) submit the utility application. Starting with the utility application before checking free zone conditions can lead to design revisions if the free zone imposes unexpected structural or access constraints.
Contractor Requirements in Free Zones
Utility Approval Is Non-Negotiable
Regardless of free zone status, the contractor must be approved by the relevant utility:
- Dubai free zones: DEWA-accredited contractor (Category A for up to 50 kW, B for 50–150 kW, C for above 150 kW)
- Abu Dhabi free zones: ADDC-approved PV integrator and consultant
- Northern Emirates free zones: EtihadWE-approved contractor
Free Zone Registration May Be Additional
Some free zones maintain their own contractor registration databases. This is not a substitute for utility approval, but it may be a prerequisite for obtaining site access passes, working permits, or facility management coordination.
| Free Zone | Additional Contractor Registration |
|---|---|
| JAFZA | JAFZA contractor registration for site access |
| DMCC | DMCC facility management coordination |
| ADGM | ADGM building management approval for contractors |
| KIZAD | KIZAD infrastructure department notification |
Verify with your free zone’s operations team whether your chosen utility-approved contractor also needs free zone registration. If the contractor has worked in the zone before, they may already hold registration.
C&I Solar in Free Zones: Practical Considerations
Load Profile Alignment
Free zone facilities — warehouses, logistics centres, data centres, manufacturing plants — typically have high daytime consumption that aligns well with solar generation. This maximises self-consumption and reduces reliance on net metering credits. For C&I customers, self-consumption rates of 70–90% are common, making the economics stronger than for residential customers with more variable load profiles.
Roof Space and Structural Capacity
Free zone warehouses and industrial buildings often have large, unobstructed flat roofs ideal for solar. However, older buildings may lack the structural capacity for ballasted mounting systems. A structural survey by a UAE-registered engineer is standard practice before finalising the system design. Some free zones require the structural survey to be submitted as part of their building approval process.
Multi-Tenant Buildings
In multi-tenant free zone buildings, roof rights are typically controlled by the building owner or master developer, not individual tenants. Solar projects in these buildings require:
- Written roof access agreement from the building owner
- Coordination with facility management for crane access, material staging, and electrical routing
- Agreement on how generation is allocated among tenants (if the system serves multiple meters)
- Clarification on who holds the utility connection agreement
For buildings where the landlord holds the master DEWA or ADDC account and sub-meters to tenants, the landlord must be the applicant for the solar connection. Individual tenants cannot apply independently.
Lease Term vs System Payback
Free zone commercial leases typically run 1–3 years with renewal options. Solar system payback periods range from 5–9 years for C&I customers. This creates a financing consideration: if the tenant installs the system but does not renew the lease, the unamortised investment may not be recoverable. Common structures to address this:
- Landlord-owned system: The building owner installs solar and recovers costs through service charges or a green energy surcharge
- Behind-the-meter PPA: A third-party developer owns the system and sells power to the tenant at a discounted rate; the PPA can be assigned to successor tenants
- Lease term matching: Size the system to match the remaining lease term, accepting a shorter payback at the cost of lower total savings

Common Free Zone Solar Mistakes
| Mistake | Why It Happens | Consequence |
|---|---|---|
| Assuming free zone authority handles solar approval | Misreading federal law inclusion of free zones | Delay when redirected to DEWA/ADDC; may miss application windows |
| Using a mainland contractor not utility-approved | Contractor claims “free zone experience” | Application rejected; must restart with approved contractor |
| Ignoring free zone structural approval | Focusing only on utility process | Installation halted by free zone facilities team; redesign required |
| Omitting tenancy amendment for energy infrastructure | Legal team not consulted | Dispute over who owns the solar asset at lease end |
| Sizing for export without checking net metering rules | Applying feed-in tariff assumptions from other markets | Oversized system generates non-revenue credits that never cash out |
| Not confirming roof rights in multi-tenant buildings | Assuming tenant has unrestricted roof access | Installation blocked by building owner or facility management |
Free Zone-Specific Building Codes
Some free zones have adopted building codes that affect solar installation details:
JAFZA and KIZAD: Industrial building codes specify minimum fire separation distances and access pathways on roofs. Solar arrays must leave clear maintenance corridors and firefighter access routes. These requirements are stricter than some mainland municipalities.
ADGM: The ADGM building management guidelines require that any building exterior modification — including facade-mounted panels — receive prior written approval. ADGM also requires that all electrical contractors working in ADGM buildings hold UAE-registered electrician licenses in addition to utility approval.
DMCC: Multi-tenant towers in DMCC require facility management approval for any roof penetration, cable routing through common areas, or electrical work affecting the building’s main distribution board.
Always request the current free zone engineering guidelines before finalising the system design. These documents are typically available from the free zone’s facilities or operations department.
VAT and Customs for Free Zone Solar Equipment
Solar power generation equipment — panels, inverters, and related components — is zero-rated for VAT across the UAE, including free zones. However, free zone companies should note:
- Equipment imported into a free zone for installation within that free zone typically moves under free zone customs procedures
- If equipment is imported into a free zone but installed on the mainland, standard mainland customs and VAT rules apply
- Free zone companies should confirm with their free zone customs authority that solar equipment qualifies for the zero-rating at the point of import

Frequently Asked Questions
Do free zones have separate solar approval processes?
No. Federal Decree-Law No. 17 of 2022 explicitly includes free zones. The applicable utility is still the emirate-level distributor: DEWA for Dubai free zones (JAFZA, DAFZA, DMCC), ADDC for Abu Dhabi free zones (ADGM, KIZAD, twofour54). The free zone authority does not issue separate solar approvals — you apply through the same utility channels as mainland premises.
What additional requirements do free zones impose?
While solar approval comes from the utility, free zone authorities may impose additional conditions: structural approval for rooftop works, tenancy contract amendments for energy infrastructure, building management approval for multi-tenant facilities, and adherence to free zone-specific building codes. Check with your free zone authority before submitting the utility application.
Can I use a mainland-approved contractor in a free zone?
The utility (DEWA or ADDC) requires its own approved contractor list, regardless of free zone status. However, some free zones maintain additional contractor registration requirements. Verify that your chosen contractor is approved by both the utility and the free zone authority.
Does being in a free zone change the maximum system size?
No. The same capacity limits apply: 1 MW per plot under DEWA Shams Dubai, 5 MW per premises under ADDC energy netting. Free zone status does not increase or decrease these limits.
Can a free zone company sell solar power to other companies in the same free zone?
No. There is no peer-to-peer solar trading or open retail electricity market in the UAE. The DEWA and ADDC net metering frameworks only permit on-site generation and self-consumption with surplus credited to the same account. Selling power to a neighbouring company in the same free zone is not permitted under current regulations.
Do free zone companies pay VAT on solar equipment?
Solar power generation equipment is zero-rated for VAT across the UAE. Free zone companies should confirm with their free zone customs authority that the zero-rating applies at the point of import, as customs procedures in free zones differ slightly from mainland imports.
What happens to the solar system if I move out of the free zone?
This depends on the tenancy agreement and who owns the system. If the tenant owns the system, they may be able to remove it (subject to making good the roof), but the net metering credits are tied to the utility account and cannot be transferred. If the landlord owns the system, it stays with the building. A behind-the-meter PPA structure, where a third-party developer owns the system, can be assigned to successor tenants under the PPA terms.
