How NAMA tariff works

Oman residential electricity is distributed through three regional companies under the NAMA umbrella: Mazoon Electricity in the south, Majan Electricity in the interior, and Muscat Electricity Distribution Company in the capital area. Tariff structure is broadly aligned: tiered baisas-per-kWh pricing across 5 consumption bands. Subsidized residents pay roughly 10 to 30 baisas per kWh depending on tier; customers on the Cost-Reflective Tariff (high-income residents and large premises) face materially higher rates. Oman applies a standard 5 percent VAT on top. Commercial, industrial, and governmental customers pay separate tariffs not covered here.

Worked example

A typical 3-bedroom Muscat villa using 1,500 kWh in milder months pays an energy charge in the range of OMR 15-30 depending on band, plus a small fixed meter fee. VAT at 5 percent applies on top. Summer cooling can push consumption above 4,000 kWh, where higher tariff bands apply; budget plus 50 percent for peak hot months. Cost-Reflective Tariff customers (high-income or large premises) face higher per-kWh rates than the standard subsidized schedule.

Frequently asked questions

How is NAMA residential tariff structured?
Oman residential electricity uses tiered baisas-per-kWh pricing across 5 consumption bands, ranging roughly from 10 to 30 baisas (1 OMR = 1000 baisas). The exact rate depends on consumption tier and whether the customer is on the subsidized schedule or the Cost-Reflective Tariff.
Is VAT charged on the NAMA bill?
Yes. Oman applies a standard 5 percent VAT on top of the electricity charge and any fixed fees.
What is the Cost-Reflective Tariff (CRT)?
CRT is a non-subsidized tariff schedule introduced for high-income residents and large premises. Customers on CRT pay materially higher per-kWh rates than the standard subsidized residential schedule.
Which company provides electricity in my area?
Distribution is split by region: Mazoon Electricity covers the south, Majan Electricity covers the interior, and Muscat Electricity Distribution Company serves the capital area. Tariff structure is broadly aligned across the three.
Why is my actual NAMA bill different from the calculator?
Real bills include water charges, fixed service fees, regional adjustments, and the standard 5 percent VAT. This calculator estimates the residential electricity component only.
