Grid Architecture
The UAE’s electricity system operates through four primary utility entities, each serving distinct geographic territories. The Emirates Water and Electricity Company (EWEC) manages generation procurement for Abu Dhabi, the Dubai Electricity and Water Authority (DEWA) operates Dubai’s integrated utility, the Sharjah Electricity, Water, and Gas Authority (SEWA) covers Sharjah, and the Federal Electricity and Water Authority (FEWA) serves the northern emirates of Ajman, Umm Al Quwain, Ras Al Khaimah, and Fujairah.
Total installed generation capacity across the federation exceeds 38 GW, serving peak demand that reached approximately 32 GW in summer 2025. The structural oversupply provides reserve margins but carries cost implications in the form of underutilised capacity payments.
Generation Mix Evolution
| Source | 2020 Share | 2025 Share (est.) | 2030 Target |
|---|---|---|---|
| Natural Gas | 94% | 76% | 60% |
| Nuclear (Barakah) | 0% | 14% | 18% |
| Solar PV | 4% | 8% | 15% |
| CSP & Wind | 1% | 1.5% | 4% |
| Waste-to-Energy | <1% | 0.5% | 3% |
The commissioning of all four Barakah nuclear units by 2024 represents the most significant structural shift in the UAE’s power mix in decades. At full output, Barakah provides approximately 5.6 GW of baseload zero-carbon generation, displacing substantial gas volumes that can be redirected to export or industrial feedstock.
Demand Dynamics
UAE electricity demand exhibits extreme seasonality driven by summer cooling loads. Peak-to-trough demand variation can exceed 50 per cent, creating challenges for grid balancing and capital utilisation. District cooling networks, building efficiency codes, and demand-side management programmes are gradually moderating this seasonal swing, though air conditioning remains the dominant load driver.
Per capita electricity consumption in the UAE is among the highest globally, reflecting both climate-driven cooling requirements and historically subsidised tariff structures. Tariff reform programmes across Abu Dhabi and Dubai have introduced tiered pricing to incentivise conservation without imposing excessive burden on residential consumers.
GCC Interconnection
The GCC Interconnection Authority (GCCIA) links the UAE grid with Saudi Arabia, Kuwait, Bahrain, Qatar, and Oman through a 1,200 MW high-voltage backbone. Current utilisation of this interconnection remains below design capacity, constrained by differing market structures and regulatory frameworks across member states. Expanding cross-border trade in electricity, particularly to export surplus solar generation during daylight hours, represents a significant opportunity that has yet to be fully realised.
Smart Grid Modernisation
DEWA has been the most aggressive adopter of smart grid technology, deploying advanced metering infrastructure across more than 95 per cent of its customer base. The Shams Dubai programme enables distributed solar generation with net metering, while blockchain-based peer-to-peer trading pilots have positioned Dubai as a testbed for decentralised energy markets.
Abu Dhabi’s EWEC is implementing AI-driven demand forecasting and grid optimisation systems to improve dispatch efficiency and integrate variable renewable generation. The challenge across both systems is cybersecurity — as grid digitalisation deepens, attack surface area expands proportionally.

Outlook
The UAE’s power grid is in the midst of its most significant transformation since the federation’s founding. The simultaneous integration of nuclear baseload, variable solar generation, battery storage, and smart grid infrastructure requires unprecedented coordination across multiple utility operators. Success in managing this transition will determine not only electricity costs and reliability but also the UAE’s credibility in meeting its Net Zero 2050 emissions commitments.
