Al Ain and the eastern region of Abu Dhabi emirate are served by AADC (Al Ain Distribution Company), a separate legal entity from ADDC with its own approved contractor lists, application process, and connection agreement. The energy netting framework is the same — surplus solar exported to the grid is credited as kWh offsets against future bills — but AADC projects must use AADC-approved consultants and integrators, and applications are submitted through AADC channels, not ADDC. This guide covers the full AADC-specific process from contractor selection through commissioning. For the broader Abu Dhabi regulatory framework, see the UAE solar compliance hub.
Critical: AADC and ADDC Maintain Separate Approved Contractor Lists
A contractor approved by ADDC for Abu Dhabi city projects is not automatically approved by AADC for Al Ain projects. AADC publishes its own approved PV consultant list and approved PV integrator list on aadc.ae. Engaging an ADDC-approved contractor for an Al Ain site without checking AADC’s list will result in application rejection. Verify the contractor’s current AADC status before signing any engagement — lists are updated periodically and approval can lapse.
How AADC Energy Netting Works
AADC operates under the same Small-Scale Solar PV Energy Netting Regulation as ADDC. The mechanism is simple: when your solar system generates more electricity than the premises consumes, the surplus flows to the AADC grid. A bidirectional meter records the export, and AADC credits those kWh against your future electricity bills.
No cash payment. The regulation does not permit monetary compensation for exported surplus. Credits are kWh offsets only, valued at your own applicable tariff rate. There is no fixed export price and no mechanism to cash out accumulated credits.
Credits carry forward indefinitely. Unused kWh credits roll from one billing period to the next with no expiry date. This benefits Al Ain customers whose consumption is seasonal — mild winter months generate surplus that offsets summer air-conditioning loads.
AADC Tariff Rates (2025)
AADC applies the same dual-tariff structure as ADDC, because both operate under DOE pricing policy.
| Customer Category | Tariff Rate (AADC, 2025) |
|---|---|
| UAE Nationals — residential | 6.7–7.5 fils/kWh (heavily subsidised) |
| Expatriates — residential | 26.8–30.5 fils/kWh |
| Commercial | AED 0.20/kWh (20 fils/kWh) |
| Small industrial (under 1 MW) | AED 0.286/kWh (28.6 fils/kWh) |
The financial value of each exported kWh depends entirely on the customer’s tariff category. An expatriate residential customer in Al Ain receives roughly four times the per-kWh credit value of a UAE National with the same system. This directly affects payback period and system sizing recommendations.
AADC vs ADDC: Key Differences
Although both companies operate under the same DOE regulation, they are separate entities with separate processes.
| AADC | ADDC | |
|---|---|---|
| Coverage area | Al Ain city and Al Ain governorate | Abu Dhabi city, Ruwais, coastal areas, western emirate |
| Website | aadc.ae | addc.ae |
| Approved PV integrator list | Published at aadc.ae | Published at addc.ae |
| Approved PV consultant list | Published at aadc.ae | Published at addc.ae |
| Connection Agreement | AADC PV Connection Agreement | ADDC PV Connection Agreement |
| Bidirectional meter installation | By AADC | By ADDC |
| Network design guidelines | AADC Electricity Network Design Guidelines EN-804 | ADDC network design guidelines |
The most common delay in Al Ain projects occurs when Abu Dhabi city-based contractors assume their ADDC approval covers AADC territory. It does not. Always check the AADC list specifically.
Confirm Your Utility Before Starting
If your project site is near the boundary between ADDC and AADC territory, check the existing electricity bill — it shows the billing entity. The energy netting application must go to the same utility that holds the supply agreement. When in doubt, contact AADC customer service with the premises account number to confirm jurisdiction.
System Eligibility for AADC
The same eligibility rules apply across both ADDC and AADC territories.
Existing supply agreement required. The applicant must hold an active electricity supply agreement with AADC at the premises, in their own name. Tenants whose supply is in the landlord’s name cannot apply independently.
Maximum 5 MW per premises. Systems above 5,000 kW on the LV network move into utility-scale procurement through EWEC, not the energy netting framework.
On-site generation only. Wheeling power from one site to another through the AADC grid is not permitted. The system must generate for consumption at the same premises.
LV network connection. Systems connect at the existing low-voltage supply point. HV connections require a separate utility-scale process.
Equipment conformity. All panels, inverters, and protection equipment must comply with applicable IEC standards and the QCC Conformity Assessment Scheme. Equipment without valid UAE market conformity documentation is rejected at RSB review.
The AADC Solar Application Process
The five-step sequence for AADC mirrors the ADDC process, with AADC substituted at every utility interaction point.
Obtain Municipal Building Permits
Secure structural and building permits from Al Ain Municipality (or the relevant municipality for your site in the eastern region) before approaching AADC. The municipality confirms the structure can support panel loading and that the installation complies with local planning codes. The permit number is included in the AADC submission package.
Engage AADC-Approved PV Consultants and Integrators
Download the current approved consultant and approved integrator lists from aadc.ae. Engage an approved consultant to prepare the technical design package for RSB submission. Engage an approved integrator for physical installation. Both must be on AADC’s list — not ADDC’s. Using an unapproved contractor causes immediate rejection.
Submit Technical Design Package to RSB
The approved consultant prepares and submits the full RSB design package: site plan, single-line diagram, system sizing calculations confirming 5 MW compliance, equipment datasheets (IEC 61215 and IEC 61730 panels; IEC 62109-1/-2 inverters; IEC 62116 anti-islanding), earthing and protection design per Abu Dhabi Electricity Wiring Regulations 2020, and competency certificates for both consultant and integrator. RSB issues written approval before any installation begins.
Sign the AADC PV Connection Agreement
With RSB approval in hand, sign the PV Connection Agreement with AADC. The agreement defines netting terms, metering requirements, and technical conditions. You must hold the active electricity supply agreement for the same premises in your own name. AADC then schedules bidirectional meter installation at no cost.
Complete Installation and Commissioning
The approved integrator installs the system to the RSB-approved design. AADC conducts a final inspection and installs the bidirectional meter. Do not energise the system or export to the grid until AADC has installed the meter and issued written authorisation to connect. Energising before approval breaches the Connection Agreement.

Pro Tip: AADC-Specific Network Design Guidelines
AADC publishes its own Electricity Network Design Guidelines (document EN-804) that supplement the Abu Dhabi Electricity Wiring Regulations 2020. Your approved consultant should reference both documents in the design package. RSB reviewers check for AADC-specific requirements when the project is in AADC territory — omitting EN-804 references can trigger revision requests.
Technical Standards for AADC Installations
All equipment and designs must comply with the following standards. RSB checks conformity at design review.
| Standard | Applies To | Notes |
|---|---|---|
| Abu Dhabi Electricity Wiring Regulations 2020 (DOE) | All electrical design and installation | Primary Abu Dhabi wiring standard |
| IEC 61215 | PV modules | Module design qualification and type approval |
| IEC 61730-1/-2 | PV modules | Module safety qualification |
| IEC 62109-1/-2 | Inverters | Safety of power converters for use in PV systems |
| IEC 62116 | Inverters | Anti-islanding protection |
| AADC Electricity Network Design Guidelines EN-804 | All AADC-connected systems | AADC-specific network design requirements |
| QCC Conformity Assessment Scheme | Modules, inverters, mounting | Abu Dhabi quality conformity scheme |
| ECAS via MoIAT | Equipment entering UAE market | Federal-level market conformity |
| RSB Solar PV Installation Guidance Document | All installations | Published at rsb.gov.ae and doe.gov.ae |
QCC and ECAS are distinct. QCC (Quality and Conformity Commission) operates the Abu Dhabi conformity assessment for small-scale solar. ECAS (Emirates Conformity Assessment Scheme), administered by MoIAT, is the federal-level scheme for regulated products entering the UAE market. Both are required.

Financial Considerations in Al Ain
Climate and Generation Profile
Al Ain’s climate differs from Abu Dhabi city. Higher elevation and slightly lower humidity can improve panel efficiency, but summer temperatures still exceed 45°C — which reduces inverter efficiency and increases cable derating. Annual solar irradiance in Al Ain is approximately 2,100–2,200 kWh/m²/year, comparable to Abu Dhabi city. System yield calculations should use Al Ain-specific weather files rather than generic Abu Dhabi data.
Tariff Impact on Payback
The same dual-tariff structure applies:
| Parameter | UAE National | Expatriate |
|---|---|---|
| Applicable tariff | ~7 fils/kWh | ~28 fils/kWh |
| Annual value of 10 kW system (~16,000 kWh) | AED 1,120 | AED 4,480 |
| Simple payback (AED 40,000 system) | ~36 years | ~9 years |
For commercial customers at AED 0.20–0.286/kWh, payback typically falls in the 5–8 year range depending on system size and self-consumption ratio.
Al Ain C&I Solar Opportunities
Al Ain has a significant agricultural and light industrial base — date processing, dairy farms, and manufacturing facilities with large roof areas and high daytime consumption. These C&I customers often see strong solar economics because their load profiles align closely with solar generation, maximising self-consumption and minimising reliance on credit carry-forward.

Frequently Asked Questions
What is the difference between ADDC and AADC solar programs?
ADDC serves Abu Dhabi city and the western region; AADC serves Al Ain and the eastern region. Both operate under the same Small-Scale Solar PV Energy Netting Regulation, but each maintains separate approved consultant and integrator lists. A contractor approved by ADDC is not automatically approved by AADC. Applications must be submitted to the utility serving your specific location.
What is the maximum system size for AADC energy netting?
AADC allows systems up to 5 MW per premises under the energy netting regulation. Exported surplus is credited against future bills as kWh offsets with no cash payment. Credits carry forward indefinitely.
How do I find AADC-approved solar contractors?
AADC publishes its approved PV integrator and consultant lists on aadc.ae. Both the design consultant and installation contractor must appear on AADC’s approved list. Verify approval status before engaging any firm — using an unapproved contractor will void the application.
Does AADC pay cash for exported solar electricity?
No. The Abu Dhabi Small-Scale Solar PV Energy Netting Regulation explicitly prohibits monetary compensation for surplus exports. Credits are kWh offsets only, valued at the customer’s own tariff rate. There is no cash-out mechanism.
Do I need RSB approval for an AADC solar project?
Yes. RSB approval is mandatory for all small-scale solar PV projects in Abu Dhabi emirate, including AADC territory. The approved consultant submits the design package to RSB before installation begins. RSB written approval is required before AADC will sign a Connection Agreement.
Can I use the same contractor for ADDC and AADC projects?
Only if that contractor appears on both the ADDC approved list and the AADC approved list. Approval by one utility does not confer approval by the other. Check both lists independently. Some larger contractors hold approval from both utilities; smaller firms may hold only one.
