DEWA Solar PV Generation and Export Metering Specifications

Key Takeaways

• DEWA mandates a dual energy meter framework for solar PV systems (August 2026).
• A generation check-meter tracks gross PV production and is part of the connection fee (August 2026).
• A bi-directional smart grid meter measures grid import and export, installed free of charge (August 2026).
• Excess solar generation rolls over month-to-month to offset future bills, with no cash-out (August 2026).

What are DEWA's Metering Specifications for Solar PV?

The Dubai Electricity and Water Authority (DEWA) implements a specific metering architecture for solar photovoltaic (PV) installations under its Shams Dubai initiative. This system ensures accurate measurement of both solar electricity generation and consumption. DEWA's "Rules governing dual smart meter installation, generation tracking, and billing integration in Dubai" outline these requirements.

DEWA requires a "Dual Energy Meter Framework" for all solar PV systems. This means "two dedicated energy meters are installed by DEWA" at the premises. This framework is designed to measure "solar electricity generated and electricity consumed on the premises." The purpose is to provide a clear record of energy flows for billing and system performance tracking.

How Does DEWA's Dual Metering System Work?

DEWA's metering system involves two distinct meters, each with a specific function. This dual setup allows for precise monitoring of your solar PV system's contribution and your overall energy balance with the grid.

The Generation Check-Meter

The first meter is the generation check-meter. This meter is "supplied and installed by DEWA." Its primary role is "to record total gross generation produced by the photovoltaic array." This means it measures all electricity your solar panels produce before any of it is consumed on-site or exported to the grid. The generation check-meter provides a direct measure of your solar system's output.

The Bi-Directional Smart Grid Meter

The second meter is the bi-directional smart grid meter. This meter "measures active power exported to the DEWA grid and imported from the grid for billing offset." Unlike traditional meters that only measure consumption, the bi-directional meter tracks energy flow in both directions. It records how much electricity you draw from DEWA and how much surplus solar electricity you send back to the grid.

This dual system ensures that DEWA has a comprehensive understanding of your energy profile, allowing for accurate billing and management of the grid.

What are the Costs Associated with DEWA Solar Meters?

Understanding the costs involved with DEWA's metering infrastructure is important for budgeting your solar PV project. DEWA has distinct policies regarding the charges for each type of meter.

Generation Check-Meter Costs

The "Generation check-meter cost" is "charged to the customer as part of the one-off standard connection fee." This means the cost for the meter that tracks your gross solar production is integrated into the initial fees you pay to connect your solar system to the DEWA grid. This is a one-time expense associated with the installation process.

Bi-Directional Smart Grid Meter Costs

In contrast, the "Bi-directional meter cost" is handled differently. This meter is "Installed by DEWA without any charge to the customer." This policy aims to encourage solar adoption by removing a direct cost barrier for the meter that facilitates grid interaction and net billing.

Generation Check-Meter Waiver for Villa Communities

DEWA offers a specific waiver for the generation check-meter under certain conditions. The "Generation check-meter waiver" applies to "certain Shams Dubai projects < 10kW in residential villa communities with identical installations." In these cases, "sample testing is applied" instead of requiring an individual generation meter for every property. This waiver can reduce the upfront connection costs for eligible smaller-scale residential solar projects.

How Does DEWA Handle Excess Solar Generation?

DEWA's Shams Dubai program employs a net billing system to manage solar electricity generated by customers. This system allows you to benefit from the electricity your solar panels produce, even if you generate more than you immediately consume.

Net Billing Tariff Offset

The core mechanism is the "Net billing offset." This means "Exported kilowatt-hours offset imported kilowatt-hours within the monthly billing period at the customer's applicable tariff slab." If your solar system produces more electricity than you consume in a given month, the excess generation is credited against your imported electricity. This reduces your overall electricity bill.

Surplus Credit Rollover

For any remaining excess generation, DEWA implements a "Surplus rollover" mechanism. "Excess generated kilowatt-hours roll over month-to-month to offset future consumption bills." This ensures that any surplus electricity you generate is not lost. It can be used to reduce your bills in subsequent months when your consumption might be higher or your solar production lower.

It is important to note that this "Surplus rollover" occurs "without monetary cash-out." DEWA does not pay customers for excess electricity exported to the grid. The benefit is solely in offsetting future electricity consumption. Additionally, "Exported electricity cannot be cashed out or transferred across non-contiguous consumer premise accounts." This means your surplus credits are tied to your specific property and cannot be sold or moved to another location.

Verifying DEWA's Metering Requirements

We verified these specifications by consulting official DEWA documentation on 23 August 2026. The information presented here is drawn directly from DEWA's published "Shams Dubai Solar PV Metering Architecture and Specifications" available on their official website. This ensures that the details provided are current and accurate as per DEWA's regulations.

Important Considerations for Your DEWA Solar Project

Navigating the requirements for a solar PV installation in Dubai involves understanding not just the technical aspects but also the regulatory framework. The metering specifications are a critical part of this.

When planning your solar system, consider the implications of the dual-metering setup. The generation check-meter provides data on your system's performance, while the bi-directional meter manages your interaction with the grid. For detailed guidance on the overall process, you may find our guide on DEWA solar PV grid connection stages and capacity limits helpful.

Choosing the right contractor is also essential. DEWA has specific certification requirements for solar PV contractors. Our guide on DEWA solar PV contractor certification and safety standards can help you identify qualified professionals.

For those interested in the broader smart grid integration, the DEWA DRRG smart metering and grid connection guide provides further context on how distributed renewable resources are managed within DEWA's network.

Finally, be aware of the strict regulations regarding metering equipment. "Tampering with generation or export meters results in immediate disconnection and administrative penalties under DEWA regulations." Ensuring compliance with all DEWA rules is crucial for the successful and uninterrupted operation of your solar PV system. You can also use a solar sizing tool to help plan your system's capacity in line with DEWA's guidelines.
