EtihadWE — Etihad Water and Electricity — is the utility you deal with for solar grid connection across the northern Emirates. The name FEWA (Federal Electricity and Water Authority) still appears widely in older contracts, permit templates, and search results, but the legal entity was absorbed into EtihadWE in 2020. For all current applications and compliance work, FEWA and EtihadWE are the same thing.
The Distributed Solar System (DSS) program, launched on 17 September 2024, is EtihadWE’s answer to DEWA’s Shams Dubai scheme. It covers Ajman, Umm Al Quwain, Ras Al Khaimah, and Fujairah. Customers can install grid-tied solar, export surplus to the EtihadWE network, and receive bill credits. The 2024 launch came with a 20 MW aggregate cap on a first-come, first-served basis. Two key differences from DEWA: credits expire at the end of the calendar year (DEWA credits never expire), and there is no named self-service online portal comparable to DEWA’s Hab Reeh — applications go through direct EtihadWE contact.
For anyone designing solar projects in the northern Emirates, these distinctions matter for financial modelling and project timelines. This guide covers the full DSS process, municipality NOC requirements by emirate, RAK’s specific Barjeel Strategy context, technical standards, and practical guidance on sizing systems so year-end credit expiry does not erode financial returns.
EtihadWE Credits Expire at Year End — DEWA Credits Do Not
This is the most commercially significant difference between the EtihadWE DSS program and DEWA’s Shams Dubai scheme. Credits earned under the EtihadWE scheme are valid within the same calendar year only. Any credits not consumed by 31 December are forfeited — there is no cash payment and no rollover. DEWA Shams Dubai credits, by contrast, never expire. If you are sizing a system for a northern Emirates customer, account for seasonal generation patterns: systems with large surpluses in summer (peak irradiance) need to carry sufficient load through winter to avoid year-end credit waste.
FEWA to EtihadWE: What Changed in 2020
FEWA — the Federal Electricity and Water Authority — was the original utility serving the northern Emirates. It was established as a federal entity and operated electricity and water infrastructure across Ajman, Umm Al Quwain, Ras Al Khaimah, Fujairah, and parts of Sharjah not covered by SEWA (the Sharjah Electricity and Water Authority).
In 2020, the UAE government issued Federal Decree Law No. 31, establishing EtihadWE as the new corporate entity to absorb and replace FEWA. The rebrand was part of a broader federal initiative to modernise utility governance and align with UAE Vision 2031 sustainability targets.
What changed for customers:
- Legal counterparty changed from FEWA to EtihadWE for new contracts and applications
- Branding and communications updated to reflect the EtihadWE name
- Corporate governance restructured as a government-owned company
What stayed the same:
- Same physical network, same connection points, same service territory
- Existing FEWA tariff agreements and contracts remained in force (treated as EtihadWE)
- Same technical teams and operational staff
- Same municipality NOC requirements (these are municipality-driven, not utility-driven)
Practical note for existing projects: If your permit, contract, or grid connection approval references FEWA, it is still valid. EtihadWE absorbed FEWA’s obligations. You do not need to reapply or renew approvals that were issued under the FEWA name. For new applications submitted from 2021 onward, reference EtihadWE throughout.
The UAE solar compliance hub covers the full regulatory landscape across all seven emirates, including DEWA (Dubai), SEWA (Sharjah), and the federal framework under which EtihadWE operates.
EtihadWE Service Area
EtihadWE covers four emirates directly and parts of a fifth:
| Emirate | Municipality | Notes |
|---|---|---|
| Ras Al Khaimah | RAK Municipality | Highest solar irradiance in UAE; Barjeel Strategy targets 600 MW rooftop by 2040 |
| Ajman | Ajman Municipality | Smallest emirate by area; primarily residential and industrial zones |
| Umm Al Quwain | UAQ Municipality | Low population density; growing industrial free zone activity |
| Fujairah | Fujairah Municipality | East coast location; slightly lower irradiance than west coast emirates |
| Northern Sharjah areas | Varies | Areas outside SEWA coverage — confirm with EtihadWE before application |
Sharjah clarification: Sharjah city and the main urban areas around Sharjah are primarily SEWA territory. EtihadWE covers some northern and eastern Sharjah enclaves. If a project is in Sharjah, confirm with both utilities which one has jurisdiction before beginning the NOC or DSS application process.
The DSS Program: How It Works
The Distributed Solar System program allows eligible customers to install grid-tied solar systems and connect them to the EtihadWE distribution network. The mechanism uses two meters and monthly comparisons to calculate bill credits.
The Two-Meter System
EtihadWE installs two meters at the customer’s premises on DSS program connection:
- Export meter: Records kilowatt-hours fed from the solar system into the EtihadWE grid
- Import meter: Records kilowatt-hours drawn from the EtihadWE grid by the customer
At the end of each billing month, EtihadWE compares the two readings:
- If imported > exported: The customer pays for the net consumption (imported minus exported) at the standard tariff
- If exported > imported: The surplus is credited to the customer’s account as a bill credit
Credits accumulate throughout the year but expire on 31 December. No cash is paid for any outstanding credit balance at year end.
Who Qualifies
| Sector | Eligible |
|---|---|
| Residential | Yes |
| Industrial | Yes |
| Agricultural | Yes |
| Commercial (office-only) | Not the primary target — confirm eligibility with EtihadWE |
The program’s public communications specifically name residential, industrial, and agricultural customers as the target segments. Commercial office buildings were not highlighted as a primary eligible category at launch. Confirm with EtihadWE directly if your project falls outside these three sectors.
EtihadWE Tariff Rates (2025)
The financial value of exported credits and consumed grid electricity depends on the applicable tariff category:
| Tariff Category | Rate (AED/kWh) |
|---|---|
| Commercial | 0.21 |
| Standard Industrial | 0.26–0.32 |
| Residential (UAE National, subsidised) | Lower tiered rates (subsidised) |
| Residential (Expatriate) | Standard tiered rates |
VAT is zero-rated for solar equipment in the UAE under the Federal Tax Authority’s zero-rating for solar panels and related components. This applies to equipment purchases, not to electricity tariffs.
Pro Tip: Use Actual Tariff Rates in Your Financial Proposals
EtihadWE tariffs differ from DEWA and ADDC rates. Do not carry over tariff assumptions from Dubai or Abu Dhabi projects when modelling northern Emirates systems. Confirm the specific customer’s tariff category and current rate with EtihadWE before finalising financial projections. Industrial customers in particular should confirm their band — the AED 0.26–0.32/kWh range for standard industrial represents a significant variance that affects payback calculations.
DSS Capacity Cap and Availability
The 2024 DSS program launched with a 20 MW aggregate capacity cap across all northern Emirates. Applications were accepted on a first-come, first-served basis, and the program closed for the year when the cap was reached.
What this means for project planning:
- The cap resets annually — a new cap (for 2025 and 2026) may apply with different limits
- Applications close when the cap is hit, regardless of application quality or project readiness
- There is no waiting list mechanism confirmed — applications submitted after cap closure are deferred to the following year’s program
- EtihadWE has not published real-time cap utilisation data at a public portal as of research date
Before beginning any northern Emirates DSS project, confirm two things with EtihadWE directly:
- Is the current year’s capacity cap still open for new applications?
- Approximately how much of the annual cap remains available?
Contact EtihadWE at etihadwe.ae or through their customer service channels to obtain current cap status. This single check can prevent significant project management issues — discovering the cap is exhausted after completing design, obtaining municipality NOC, and preparing application documents wastes months of work.
The Application Process
The DSS application process involves five sequential steps. Municipality NOC and EtihadWE grid connection approval must happen in the right order — municipality NOC first, then EtihadWE submission.
Confirm EtihadWE DSS Availability and Current Capacity Cap
Contact EtihadWE at etihadwe.ae to confirm the DSS program is still accepting applications and that the annual capacity cap has not been reached. The 2024 cap was 20 MW in aggregate across all northern emirates — first-come, first-served. New annual caps may apply for 2025 and 2026. Also confirm your premises falls within EtihadWE’s service territory (not SEWA’s).
Obtain a NOC from Your Emirate Municipality
Submit a municipal NOC application to your relevant municipality: RAK Municipality for Ras Al Khaimah, Ajman Municipality for Ajman, UAQ Municipality for Umm Al Quwain, or Fujairah Municipality for Fujairah. Provide a site plan showing roof dimensions, panel layout, structural load calculations, and system sizing. The municipality reviews whether the structure can safely support the installation. Municipal NOC approval typically takes 1–2 weeks.
Engage an EtihadWE-Approved Contractor
EtihadWE requires approved contractors modelled on the Shams Dubai framework. Contact EtihadWE directly to obtain the current list of approved companies for DSS installations. Contractors should hold relevant UAE electrical contractor licences and be familiar with IEC 62109 inverter requirements and IEC 62116 anti-islanding settings. Until EtihadWE publishes a named portal equivalent to DEWA’s Hab Reeh, direct utility contact is the primary channel.
Submit the Grid Connection Application to EtihadWE
With the municipal NOC in hand, your approved contractor submits the grid connection application to EtihadWE. The package should include: site plan and panel layout, single-line diagram, equipment datasheets (panels: IEC 61215 + IEC 61730; inverters: IEC 62109-1/-2 + IEC 62116), system sizing calculations, contractor credentials, and the municipality NOC. EtihadWE reviews and issues approval to proceed. EtihadWE indicated timelines of approximately 2–3 weeks for straightforward applications.
Install, Pass Inspection, and Commission
Install the approved system per the submitted design. After installation, EtihadWE conducts a site inspection and installs two meters — one for export and one for import. Do not energise the system or export to the grid without EtihadWE’s written sign-off. Ensure anti-islanding settings on the inverter are correctly configured — EtihadWE’s approved contractors are responsible for verifying inverter settings during commissioning.
Application Timeline Summary
| Stage | Typical Duration |
|---|---|
| Cap availability confirmed | 1–3 days |
| Municipal NOC obtained | 1–2 weeks |
| Contractor engaged and application prepared | 1–2 weeks |
| EtihadWE application reviewed and approved | 2–3 weeks |
| Installation and inspection | 1–3 weeks depending on system size |
| Dual meter installation by EtihadWE | 1–2 weeks after inspection pass |
| Total from project start to DSS billing | 6–12 weeks |
No Named Online Portal as of Research Date
Unlike DEWA’s Hab Reeh self-service portal, EtihadWE had not published a named dedicated online application portal for DSS applications as of the April 2026 research date. Applications are processed through direct engagement with EtihadWE customer service. Verify the current process at etihadwe.ae before beginning an application — the utility may have introduced a portal after this publication date.
Technical Requirements
EtihadWE’s DSS technical requirements are modelled on DEWA’s Shams Dubai framework, which is itself based on IEC international standards. The same equipment standards used for Dubai projects apply in the northern Emirates.
Equipment Standards
| Standard | Applies To | Requirement |
|---|---|---|
| IEC 61215 | Solar panels (performance) | Mandatory — all panels |
| IEC 61730 | Solar panels (safety) | Mandatory — all panels |
| IEC 62109-1 | Inverters (general safety) | Mandatory — all inverters |
| IEC 62109-2 | Inverters (grid-connected) | Mandatory — all inverters |
| IEC 62116 | Anti-islanding | Mandatory — inverter must comply |
| IEC 61727 | Grid interface characteristics | Mandatory — system design |
| IEC 60255 | Protection relays | Larger systems (confirm threshold with EtihadWE) |
ECAS Certification
All solar equipment sold in the UAE must carry ECAS (Emirates Conformity Assessment Scheme) certification, administered by the UAE Ministry of Industry and Advanced Technology (MoIAT). ECAS is mandatory for UAE market entry — it is separate from IEC type testing and certifies that the product meets UAE regulatory requirements.
DEWA Approved Equipment List as a Reference
EtihadWE has not published a separate approved equipment database as of the research date. Equipment that appears on DEWA’s approved inverter and module list for the Shams Dubai program is a reliable indicator of compliance acceptability for DSS applications. When EtihadWE’s approved contractors submit applications, they typically reference equipment already proven through DEWA’s vetting process.
Using solar design software that maintains an up-to-date component database including ECAS-certified equipment ensures that northern Emirates projects are specified with compliant components from the outset — reducing the risk of application rejection due to equipment eligibility questions.
Anti-Islanding Requirements
Anti-islanding compliance under IEC 62116 is a non-negotiable requirement. The inverter must automatically disconnect from the EtihadWE grid within the timeframe required by IEC 62116 when it detects loss of grid supply. This protects EtihadWE workers on the distribution network. EtihadWE’s approved contractors are responsible for verifying inverter anti-islanding configuration during commissioning. Incorrect anti-islanding settings are one of the most common causes of inspection failure.

Ras Al Khaimah: Barjeel Strategy and Solar Opportunity
RAK stands out among the EtihadWE service emirates as having the most developed formal solar strategy and some of the best solar resource in the UAE.
The Barjeel Strategy
RAK Municipality’s Barjeel program (the name references the traditional Arabian wind tower) sets a target of 1.2 GW total renewable energy capacity by 2040, structured as:
- 600 MW rooftop solar (distributed, customer-sited installations)
- 600 MW utility-scale solar (ground-mounted, large projects)
The overarching framework is the RAK Energy Efficiency and Renewables Strategy 2040, which targets:
- 30% reduction in energy consumption
- 20% reduction in water consumption
- 20% of energy from renewable sources by 2040
The Zero-Export History
RAK historically had a significant peculiarity compared to other UAE emirates: many rooftop solar installations were required to use zero-export configurations. Systems generated solar power for on-site consumption only, with inverters configured to prevent any surplus from being pushed onto the EtihadWE grid. Credits and net metering did not apply to these systems.
This configuration was driven by grid stability concerns in earlier years when EtihadWE’s northern network had limited capacity to absorb distributed generation. The trade-off was simpler grid management at the cost of limiting the financial case for customer solar investment.
The DSS Program Changes This
The EtihadWE DSS program launch in September 2024 fundamentally changed the situation for RAK. Customers who previously operated zero-export systems can now — subject to EtihadWE DSS application approval — switch to a grid-export arrangement and participate in the net metering credit scheme. New installations in RAK can be designed from the outset as export-enabled DSS systems.
For solar designers, this changes the financial model for RAK projects substantially. A correctly sized RAK system on the DSS program can reduce electricity bills by 60–80% for a residential or industrial customer with appropriate load profiles. Use solar design software with accurate UAE irradiance data for RAK’s location to model the generation profile correctly — RAK’s east-coast position and terrain give it slightly different seasonal irradiance patterns than Dubai or Abu Dhabi.
RAK Solar Resource
RAK benefits from one of the highest solar irradiance levels in the UAE. The emirate averages approximately 2,000–2,100 kWh/m² annual global horizontal irradiance (GHI), with excellent solar windows from March through October. The combination of high irradiance, the new DSS export capability, and the Barjeel Strategy’s ambitious targets makes RAK one of the more attractive emerging solar markets in the northern Emirates.
Calendar-Year Credits: Planning Your System Size
The calendar-year credit expiry rule is the primary sizing constraint for EtihadWE DSS systems that does not apply to DEWA systems. Understanding it correctly separates installers who set accurate client expectations from those who create disappointed customers at year end.
How Credit Expiry Works in Practice
Consider a residential customer in Ajman with a monthly electricity consumption of 1,200 kWh:
- Annual consumption: ~14,400 kWh
- Annual solar generation from a 10 kW system in the UAE: approximately 15,000–17,000 kWh (depending on orientation, shading, and losses)
On DEWA’s Shams Dubai program, the excess 600–2,600 kWh generated above consumption would carry forward indefinitely — no financial loss. On the EtihadWE DSS program, any credits not consumed by 31 December are forfeited.
If the customer has large summer surpluses (peak irradiance, peak generation, but potentially lower consumption if the building is empty in summer), those credits need to be consumed before year end or they are lost.
Sizing to Avoid Year-End Waste
| Scenario | Risk | Sizing Recommendation |
|---|---|---|
| Residential with consistent year-round load | Low — consumption tracks generation | Size at 95–105% of annual consumption |
| Industrial with seasonal shutdown (Ramadan, summer) | High — shutdown creates credit buildup | Size at 70–80% of annual consumption; model month-by-month |
| Agricultural with seasonal pump loads | Medium — irrigation season may align with peak generation | Model monthly load vs generation; cap at 90% annual coverage |
| Commercial office (5-day week, August closure) | Medium — August solar surplus builds up | Size at 80–90%; confirm August load profile |
Example Calculation for an RAK Industrial Customer
An industrial manufacturer in Ras Al Khaimah consumes 45,000 kWh/month (540,000 kWh/year). The facility operates year-round, 6 days a week.
| Month | Estimated Generation (kWh) from 300 kW system | Monthly Consumption (kWh) | Net Credit / Deficit |
|---|---|---|---|
| January | 38,000 | 45,000 | −7,000 (draws from grid) |
| February | 41,000 | 45,000 | −4,000 |
| March | 48,000 | 45,000 | +3,000 credit |
| April | 52,000 | 43,000 | +9,000 credit |
| May | 55,000 | 40,000 | +15,000 credit |
| June | 53,000 | 42,000 | +11,000 credit |
| July | 51,000 | 44,000 | +7,000 credit |
| August | 52,000 | 44,000 | +8,000 credit |
| September | 48,000 | 45,000 | +3,000 credit |
| October | 43,000 | 45,000 | −2,000 |
| November | 38,000 | 45,000 | −7,000 |
| December | 35,000 | 45,000 | −10,000 |
Summer months (March–September) generate ~56,000 kWh in cumulative credits. Winter months (October–February) consume ~30,000 kWh from the grid. Net credits consumed before year end: ~26,000 kWh. This works — no year-end expiry waste.
If the same system were sized at 400 kW instead, summer credit buildup would outpace winter consumption by roughly 25,000–30,000 kWh — potentially forfeited on 31 December. The month-by-month model, not just the annual total, is what identifies the right system size under EtihadWE’s calendar-year credit structure.
A solar design software platform that produces month-by-month generation and consumption comparisons — not just annual totals — is the practical tool for getting EtihadWE system sizing right.
Frequently Asked Questions
What is the EtihadWE DSS program and when did it launch?
The Distributed Solar System (DSS) program is EtihadWE’s distributed solar initiative, launched on 17 September 2024. It allows residential, industrial, and agricultural customers in Ajman, Umm Al Quwain, Ras Al Khaimah, and Fujairah to install grid-tied solar systems and receive bill credits for exported electricity. The program was developed with the UAE Ministry of Energy and Infrastructure and modelled on DEWA’s Shams Dubai program. A 20 MW capacity cap applied for 2024 on a first-come, first-served basis.
What is the difference between FEWA and EtihadWE?
EtihadWE (Etihad Water and Electricity) is the current legal entity that absorbed and replaced FEWA (Federal Electricity and Water Authority) in 2020 under Federal Decree Law No. 31. FEWA no longer exists as a separate entity. EtihadWE operates the electricity and water networks in Ajman, Umm Al Quwain, Ras Al Khaimah, and Fujairah. If you encounter the name “FEWA” in older contracts or documentation, treat it as EtihadWE for all current compliance and application purposes.
How do EtihadWE credits work differently from DEWA?
EtihadWE DSS credits are valid within the same calendar year only — unused credits do not carry over to the following year. This differs from DEWA’s Shams Dubai program, where credits never expire. Under the EtihadWE scheme, two meters track exported and consumed energy separately; monthly comparisons determine the net credit balance. No cash payment is made for any surplus — credits offset future bills only.
Do I need a municipality NOC for solar in Ras Al Khaimah or Ajman?
Yes. EtihadWE requires customers to obtain a NOC from their relevant emirate municipality before connecting to the DSS program. In Ras Al Khaimah, this is RAK Municipality; in Ajman, it is Ajman Municipality; in Umm Al Quwain, UAQ Municipality; in Fujairah, Fujairah Municipality. The municipality inspects the structure to confirm it can support the weight of the panels and approves the installation layout. Allow 1–2 weeks for this step.
Can Ras Al Khaimah businesses now export solar to the EtihadWE grid?
Yes, as of the DSS program launch in September 2024. RAK had historically used zero-export configurations for many rooftop installations — solar generated and consumed on-site only, with no grid export. The EtihadWE DSS program changed this, enabling residential, industrial, and agricultural customers in RAK to export surplus generation and receive bill credits. The RAK Barjeel Strategy targets 600 MW of rooftop solar as part of a 1.2 GW renewable energy goal by 2040.
