DEWA Multi-Account Solar Net Metering Rules: Aggregation and Tariff Offsetting in Dubai

Key Takeaways

• DEWA's multi-account net metering is regulated by Council Resolution No. 46 of 2014.
• Surplus solar electricity credits can be carried forward indefinitely to future billing periods.
• Offsetting solar generation is restricted to the same plot and cannot cross distinct commercial entities.
• The account hosting the solar generator is always the first to have its consumption offset.

What is DEWA's multi-account solar net metering policy in Dubai?

Dubai's multi-account solar net metering policy, part of the Shams Dubai initiative, allows you to benefit from solar energy across multiple electricity accounts within a single property. This framework is established under "council resolution number 46 of 2014, issued by HH Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, Crown Prince of Dubai and Chairman of the Dubai Executive Council" (August 2026). The resolution specifically addresses how solar electricity generated on a property can be allocated to different meters on that same plot.

The core principle is that "in the case of more than one consumption account for the producer, the electricity produced will be consumed in the real estate on the same plot to which the accounts relate" (August 2026). This means if you have multiple DEWA meters on one land parcel, such as in a villa compound or a commercial complex under single ownership, the solar energy generated can collectively reduce the bills for all those accounts. This system is designed to maximize the financial benefits of solar installation by allowing comprehensive offsetting of consumption.

How does DEWA calculate tariff slabs with solar net metering?

DEWA's net metering scheme is designed to maximize savings by optimizing how tariff slabs are applied to your electricity bill. The process involves deducting your solar exports and credits before the standard tariff structure is applied.

Specifically, "electricity exports and credits are deducted from the electricity imported from the grid, and only then are DEWA tariff slabs (and any applicable fuel surcharges) applied to calculate the bill" (August 2026). This method ensures that your remaining consumption, after solar deductions, is billed at potentially lower slab rates. This approach can lead to "more savings for customers, as residual consumption is billed at lower slab rates" (August 2026). Understanding this calculation is crucial for estimating the financial returns of a solar PV system in Dubai.

Can you aggregate solar generation across multiple properties or tenants?

DEWA's multi-account net metering has specific limitations regarding aggregation across different properties or for multiple tenants within a single building. The policy strictly confines the benefits of solar generation to the plot where the system is installed.

"Offsetting across separate plots or between distinct commercial entities is not permitted" (August 2026). This means you cannot install solar panels on one property and use the generated electricity to offset consumption on another, unrelated property you own.

For multi-tenant buildings, the rules are also precise. "Under current legislation it is not planned to offset electricity produced by a PV plant against electricity consumed by different customers" (August 2026). Instead, "you can only offset electricity consumption of the common areas of the building (lighting, air-conditioning, elevators etc.) measured by the meters you own" (August 2026). This clarifies that individual tenant meters cannot directly benefit from a building's shared solar system under the current framework.

What happens to surplus solar electricity and accumulated credits?

A key aspect of DEWA's net metering policy is the handling of surplus solar electricity and the management of accumulated credits. The system is designed to ensure that any excess energy you generate is not lost but rather carried forward to your benefit.

If your solar PV system exports more energy to the grid than your property imports during a billing period, "the invoiced value of electricity will be zero and the surplus electricity will be shown as a credit which can be brought forward in the following billing period" (August 2026). This credit has "indefinite rollover" (August 2026), meaning it does not expire and can be used to offset future consumption.

However, it is important to note that "the resolution also stipulates that the producer shall not be paid any money for the excess electricity, and set-off between this surplus and the imported energy shall be limited in accordance with the provisions of the resolution" (August 2026). This means that while you can accumulate credits to reduce future bills, you will not receive direct cash payments for any surplus electricity exported to the grid. The financial return is realized strictly through "electricity bill avoidance" (August 2026).

Furthermore, these accumulated credits are not transferable. "Accumulated net metering credits remain non-transferable to third-party accounts upon property conveyance" (August 2026). This detail is particularly relevant when considering property transactions.

How do you prioritize offsetting across multiple accounts on one plot?

When you have multiple electricity consumption accounts on a single plot with a solar PV system, DEWA allows you to define the order in which these accounts benefit from the generated solar electricity. This feature enables you to optimize your savings.

"The account hosting the generator is always the first one" to have its consumption offset (August 2026). This ensures that the primary account linked to the solar installation receives immediate benefit. For "the order of the subsequent ones will be determined by you during the connection application process" (August 2026).

This flexibility allows you to "optimise your total invoiced amount by choosing an order where the accounts with the highest consumption are offset first" (August 2026). By strategically prioritizing accounts with higher electricity usage, you can maximize the reduction in your overall DEWA bill.

What are the implications for property sale or transfer?

The transfer of property that hosts a solar PV generator has specific rules concerning the generator itself and any accumulated credits. These provisions ensure clarity during property transactions.

"Should you decide to sell or rent the property that hosts your Solar PV generator, you can agree with the new owner or tenant to transfer your generator to their account" (August 2026). This allows the solar asset to remain with the property and continue benefiting the new occupants.

However, it is crucial to understand the policy regarding accumulated credits: "your accumulated credit cannot be transferred to the new owner’s or tenant’s account" (August 2026). As noted earlier, "accumulated net metering credits remain non-transferable to third-party accounts upon property conveyance" (August 2026). This means any unused credits you have accrued will not pass to the new property owner or tenant.

How do we verify DEWA's net metering rules?

We verify DEWA's net metering rules by directly consulting official sources. Our information is drawn from the Dubai Electricity and Water Authority's (DEWA) public statements and official documents. Specifically, we reference the DEWA website's sections on Shams Dubai, including their dedicated FAQ pages and information on strategic initiatives. All cited information, including details on Council Resolution No. 46 of 2014 and specific policy provisions, was accessed and confirmed on August 23, 2026. This approach ensures that the regulatory details we present are current and directly reflect DEWA's published guidelines.

What are the financial incentives and limitations of Shams Dubai?

The Shams Dubai initiative, supported by DEWA's net metering rules, aims to promote distributed solar energy and contribute to the "Dubai Integrated Energy Strategy and Clean Energy Strategy targets" (August 2026). While it offers significant financial benefits, it operates within a specific incentive structure.

The primary financial incentive is "electricity bill avoidance" (August 2026). By generating your own electricity, you reduce your reliance on grid power, directly lowering your monthly DEWA bills. This is further enhanced by the indefinite rollover of surplus credits, as discussed previously.

However, it is important to note the limitations regarding direct financial incentives. "No tax or other incentives are currently being offered" (August 2026). This means that the financial returns from installing a solar PV system under Shams Dubai are realized exclusively through the reduction of your electricity expenses, rather than through direct subsidies or tax breaks.

Additionally, system commissioning requires signing "the tripartite connection agreement between customer, contractor, and DEWA" (August 2026), ensuring all parties are aligned with the regulatory framework.
