DEWA DRRG Smart Metering and Grid Connection: A Guide for Solar Installations

Key Takeaways

• DEWA mandates a dual metering architecture for solar, including a generation check-meter and a bi-directional smart meter.
• The PV generation check-meter can be waived for projects under 10kW in specific community types.
• A standard connection fee of AED 1500 is charged for each renewable generator (August 2026).
• Installations above 100kW require a successful plant performance test before final connection.

How does DEWA manage smart metering and grid connection for solar?

DEWA (Dubai Electricity and Water Authority) manages smart metering and grid connection for solar installations through its Distributed Renewable Resources Generation (DRRG) program. This program, part of the Shams Dubai initiative, outlines specific technical standards and regulatory provisions. These provisions ensure safe and efficient integration of solar power into the grid, covering aspects from metering to connection fees and equipment requirements.

How do we verify DEWA's grid connection requirements?

We verify DEWA's grid connection requirements by directly consulting the official DEWA website. Our information is drawn from the Shams Dubai FAQ section and the Solar Community Connection Process pages. We accessed these sources on 23 August 2026 to ensure the accuracy and currency of the published details.

What are the metering requirements for solar under Shams Dubai?

DEWA implements a dual metering architecture for solar installations. This system includes a "Generation check-meter" to measure the electricity produced by your solar panels. It also includes a "bi-directional smart meter" that measures the power you export to DEWA's grid and the power you import from it. The bi-directional smart meter is installed by DEWA at no additional cost beyond normal service charges (August 2026).

The PV Generation check-meter can be waived for specific Shams Dubai projects under 10kW. This waiver applies to homogeneous villa communities or non-saturated individual buildings (August 2026).

What are the costs and thresholds for connecting solar to the DEWA grid?

Connecting your solar system to the DEWA grid involves a standard connection fee and specific thresholds for larger installations. DEWA charges a one-off connection fee of AED 1500 for each renewable generator. This fee covers the cost of procuring and installing the generation check-meter (August 2026).

For larger systems, specifically those with an installed capacity of over 400kW, the cost of dedicated equipment for grid integration might be added to the standard connection fee (August 2026). Additionally, installations above 100kW require a successful plant performance test before inspection and final connection (August 2026).

What technical standards must solar inverters meet for DEWA connection?

Inverters used in DEWA-connected solar systems must meet specific technical standards. They must have an efficiency above 95% and come with a general warranty for 10 years. Inverters must also be protected from direct solar radiation and water.

An automatic decoupling device, also known as Interface Protection, must be installed between the inverter and the network connection point. This is required if the inverter does not already incorporate such a device. This measure prevents islanding into de-energized circuits, ensuring grid stability and safety.

How do you navigate the DEWA solar connection process?

The DEWA solar connection process consists of three main stages. Stage A involves getting solar permits and submitting the connection application. Stage B covers inspection and the actual connection of your system. Stage C is when your system begins generation.

Fieldwork, NOC applications, and inspection requests must be performed by DEWA-enrolled Electrical & DRRG Solar PV consultants and contractors. You must also obtain a Building Permit from the competent Authority/Entity (e.g., Dubai Municipality, Trakhees, Etihad Esco) and a structural Completion Certificate.

For a detailed walkthrough of the application steps, you can refer to our guide on the DEWA solar connection process. To understand how your generated solar power interacts with the grid, consult our Shams Dubai net metering guide. If you are in the planning stages, our guide on DEWA-approved solar panels can help you select compliant equipment. You can also use a solar sizing tool to estimate your system needs.
