Ouarzazate — The World's Largest Solar Farm
Feature Report — Renewable Infrastructure
The World's Largest
Solar Farm
Is in the Sahara
In the Moroccan desert, where Lawrence of Arabia was filmed and Game of Thrones was shot, 2 million mirrors now chase the sun — powering over a million homes and rewriting what Africa's energy future looks like.

A Desert Once Known for Film Sets
Ouarzazate sits at the edge of the Sahara, roughly 200 kilometres south of Marrakech, where the Atlas Mountains give way to open desert. For decades the city was best known as a film location — Lawrence of Arabia, The Mummy, and Game of Thrones were all shot among its ancient kasbahs and dunes.
It is now known for something else entirely. Ten kilometres outside the city, the Noor Concentrated Solar Power complex stretches across more than 3,000 hectares of scrubland and rock — an area roughly equal to San Francisco. Where extras once played desert warriors, two million sun-tracking mirrors now stand in long, silent rows, following the arc of the sun from dawn to dusk.
What Makes Noor Different from Ordinary Solar
Most solar farms use photovoltaic panels that generate electricity only when the sun shines. Noor uses Concentrated Solar Power (CSP) — a fundamentally different approach. Curved mirrors called parabolic troughs focus sunlight onto a receiver pipe filled with heat-transfer fluid, which reaches temperatures high enough to drive a steam turbine.
The crucial advantage: thermal storage. Excess heat is pumped into tanks of molten salt that can remain at over 393°C for hours. When the sun sets, the stored heat continues generating electricity — giving Noor the ability to power homes through the night, something a conventional solar farm cannot do.

Global Significance
What This Means for Africa
Morocco depends on imported fossil fuels for 95% of its energy. Noor is the centrepiece of a national strategy to reverse that dependency — aiming for a 52% renewable electricity mix by 2030. The complex already powers over 1.1 million Moroccan homes and supplies approximately 5% of the country's electricity.
The United Nations has described Noor's public-private financing structure — combining the World Bank, the African Development Bank, the European Investment Bank, and private developer ACWA Power — as a blueprint for Africa's climate-resilient energy future. It proved that utility-scale renewable infrastructure is bankable and buildable on the continent.
The Uncomfortable Truths
Noor has not been without controversy. Environmental groups raised concerns from the outset about water consumption in a region already stressed by drought — the wet-cooled Noor I plant draws from a nearby reservoir. The Saharan ecosystem displaced by the mirrors has rarely entered the headline story.
Economically, the Noor III breakdown exposed a hard reality: CSP costs remain high, at roughly $0.15 per kilowatt-hour, while new photovoltaic projects bid as low as $0.032. The technology is impressive — but increasingly expensive relative to alternatives. The question now is whether CSP's storage advantage justifies the cost gap, or whether batteries will render it obsolete.
The Price of Storage
When Noor III's molten salt tank cracked in 2024, it cost $51 million and 14 months to repair. That single failure prompted Morocco to announce that all future large-scale solar projects will use photovoltaic panels paired with lithium-ion battery storage — a technology that has dropped in price by over 90% in the past decade. The world's largest CSP complex may, in a sense, be the last of its kind.
The Precedent That Matters Most
Whatever happens next in Morocco's energy mix, Noor has already done something irreversible: it demonstrated, at continental scale, that a developing African nation could design, finance, build, and operate one of the world's most advanced renewable energy infrastructures.
That demonstration effect — visible from orbit as a shimmering rectangle in the Sahara — may matter more than the kilowatt-hours. It changed what investors, governments, and development banks believed was possible in Africa's energy landscape.
What Comes Next
Morocco is already developing the Noor Atlas project — a new generation of photovoltaic capacity replacing the CSP model. Costs have fallen so dramatically that PV plus batteries now underbids CSP at almost every auction worldwide.
In Ouarzazate, the mirrors will keep turning. A city that made its name hosting film crews is now a permanent fixture in the story of the global energy transition — not as a backdrop, but as the subject. The Sahara, long seen only as obstacle and emptiness, is quietly becoming infrastructure.
