Vast Desert Sun Farm To Help Light Up Morocco

On the edge of the Sahara desert, engineers make final checks to a sea of metal mirrors turned towards the sun, preparing for the launch of Morocco's first solar power plant.

The ambitious project is part of the North African country's goal of boosting its clean energy output with what it says will eventually be the world's largest solar power production facility.

Morocco has scarce oil and gas reserves, and is the biggest importer of energy in the Middle East and North Africa.

The plant is part of a vision to move beyond this heavy dependency and raise renewable energy production to 42 percent of its total power needs by 2020.

About 20 kilometres (12 miles) outside Ouarzazate, half a million U-shaped mirrors -- called "parabolic troughs" -- stretch out in 800 rows, slowly following the sun as it moves across the sky.

Spread over an area equivalent to more than 600 football pitches, they store thermal energy from the sun's rays and use it to activate steam turbines that produce electricity.

King Mohamed VI launched construction of the plant, called Noor 1, in 2013, at a cost of 600 million euros ($660 million) and involving roughly 1,000 workers.

Its start of operations by the end of this month was set to coincide with the conclusion of high-stakes COP21 global climate talks in Paris.

"Construction work has finished," said Obaid Amran, a board member of Morocco's solar power agency.

"We are testing components of the production units with a view to connecting them to the national grid at the end of the year."

The project's next phases -- Noor 2 and Noor 3 -- are to follow in 2016 and 2017, and a call for tenders is open for Noor 4.

- 'A million homes' -

Once all phases are complete, Noor will be "the largest solar power production facility in the world", its developers say, covering an area of 30 square kilometres (11.6 square miles).

It will generate 580 megawatts and provide electricity to a million homes.

The solar power project will also help reduce the country's greenhouse gas emissions.

The energy ministry estimates that its first solar power plant will allow the country to reduce CO2 emissions by 240,000 tonnes per year initially, and by 522,000 tonnes with the second two phases.

That is equivalent to nearly one percent of Morocco's CO2 emissions of around 56.5 million tonnes in 2011, according to World Bank figures.

The so-called "greenhouse effect" is a natural phenomenon -- an invisible blanket of gases including small amounts of carbon dioxide (CO2) -- that has made Earth warm enough for humans to survive on it comfortably.

But human activities such as burning coal and oil inject additional CO2 into the atmosphere, leading to global warming.

Humanity's annual output of greenhouse gases is higher than ever, totalling just under 53 billion tonnes of CO2 in 2014, according to the UN.

Morocco, to host next year's COP22, aims to reduce its greenhouse gas emissions by 32 percent by 2030 as it develops renewable energy production.

"We have a project to introduce 6,000 megawatts to the existing electricity production nationwide," Energy Minister Abdelkader Amara said recently.

"Two thousand megawatts will come from solar energy and 2,000 megawatts from wind and hydroelectric power."

Morocco started producing electricity at Africa's largest wind farm in its southwestern coastal region of Tarfaya last year.

"Things have been going well so far," the minister said. "We're likely to go beyond 2,000 megawatts by 2020 in the area of wind power."

But Rabat has not abandoned fossil fuels altogether -- last December, Amara announced a multi-billion-dollar project to step up Morocco's search for natural gas to produce electricity.

Morocco Poised To Become A Solar Superpower With Launch Of Desert Mega-Project

World’s largest concentrated solar power plant, powered by the Saharan sun, set to help renewables provide almost half the country’s energy by 2020.

The Moroccan city of Ouarzazate is used to big productions. On the edge of the Sahara desert and the centre of the north African country’s “Ouallywood” film industry it has played host to big-budget location shots in Lawrence of Arabia, The Mummy, The Living Daylights and even Game of Thrones.

Now the trading city, nicknamed the “door of the desert”, is the centre for another blockbuster – a complex of four linked solar mega-plants that, alongside hydro and wind, will help provide nearly half of Morocco’s electricity from renewables by 2020 with, it is hoped, some spare to export to Europe. The project is a key plank in Morocco’s ambitions to use its untapped deserts to become a global solar superpower.

When the full complex is complete, it will be the largest concentrated solar power (CSP) plant in the world, and the first phase, called Noor 1, will go live next month. The mirror technology it uses is less widespread and more expensive than the photovoltaic panels that are now familiar on roofs the world over, but it will have the advantage of being able to continue producing power even after the sun goes down.

The potential for solar power from the desert has been known for decades. In the days after the Chernobyl nuclear accident in 1986 the German particle physicist Gerhard Knies, calculated that the world’s deserts receive enough energy in a few hours to provide for humanity’s power needs for a whole year. The challenge though, has been capturing that energy and transporting it to the population centres where it is required.

As engineers put the finishing touches to Noor 1, its 500,000 crescent-shaped solar mirrors glitter across the desert skyline. The 800 rows follow the sun as it tracks across the heavens, whirring quietly every few minutes as their shadows slip further east.

When they are finished, the four plants at Ouarzazate will occupy a space as big as Morocco’s capital city, Rabat, and generate 580MW of electricity, enough to power a million homes. Noor 1 itself has a generating capacity of 160MW.

Morocco’s environment minister, Hakima el-Haite, believes that solar energy could have the same impact on the region this century that oil production had in the last. But the US$9bn (£6bn) project to make her country’s deserts boom was triggered by more immediate concerns, she said.

 “We are not an oil producer. We import 94% of our energy as fossil fuels from abroad and that has big consequences for our state budget,” el-Haite told the Guardian. “We also used to subsidize fossil fuels which have a heavy cost, so when we heard about the potential of solar energy, we thought; why not?”

Solar energy will make up a third of Morocco’s renewable energy supply by 2020, with wind and hydro taking the same share each.

“We are very proud of this project,” el-Haite said. “I think it is the most important solar plant in the world.”

Each parabolic mirror is 12 metres high and focussed on a steel pipeline carrying a ‘heat transfer solution’ (HTF) that is warmed to 393C as it snakes along the trough before coiling into a heat engine. There, it is mixed with water to create steam that turns energy-generating turbines.

The HTF is made up of a synthetic thermal oil solution that is pumped towards a heat tank containing molten sands that can store heat energy for three hours, allowing the plant to power homes into the night. The mirrors are spaced in tier formations, to minimize damage from sand blown up by desert winds.

Technicians say that the Noor 2 and 3 plants, due to open in 2017 will store energy for up to eight hours – opening the prospect of 24/7 solar energy in the Sahara, and the surrounding region.

“The biggest challenge we faced was being able to finish the project on time with the performance [level] we needed to achieve,” said Rashid al-Bayad, the project director.

But even as the first phase of the project nears completion, Morocco is eyeing grander international ambitions. “We are already involved in high tension transportation lines to cover the full south of Morocco and Mauritania as a first step,” says Ahmed Baroudi, manager of Société d’Investissements Energétiques, the national renewable energy investment firm. But he says the project’s ultimate impact will go far wider – even as far as the Middle East. “The [ultimate] objective given by his majesty the king is Mecca.”

Whether that ambition is achieved remains to be seen but exporting solar energy could have stabilising effects within and between countries, according to the Moroccan solar energy agency (Masen). Talks are ongoing with Tunisia, and energy exports northwards across the Mediterranean remain a key goal, despite the collapse in 2013 of the Desertec project, a German plan to source 15% of Europe’s energy from North African desert solar by 2050.

 “We believe that it’s possible to export energy to Europe but first we would have to build the interconnectors which don’t yet exist,” said Maha el-Kadiri, a Masen spokeswoman. “Specifically, we would have to build interconnections, which would not go through the existing one in Spain, and then start exporting.”

Spain has itself prohibited new solar projects because of a lack of interconnectors to transmit the energy to France. The EU has set a target of ensuring that 10% of each member country’s power can be transported abroad by cable by 2020.

In the meantime, Morocco is focused on using solar to meet its own needs for resource independence. This could one day include water desalination, in a country that is increasingly being hit by drought as the climate warms. Officials are keenly aware of the running they are making in what is the most advanced renewable energy programme in the Middle East and North African region.

“We are at the avante-garde of solar,” el-Kadiri says.

About US$9bn has been invested in the Noor complex, much of it from international institutions such as the European Investment Bank and World Bank and backed by Moroccan government guarantees. Undisclosed energy subsidies from Morocco’s unelected ruler, King Mohammed VI, have prevented the cost from being transferred to energy consumers.

One month before launch, over a thousand mostly Moroccan workers are still racing to fix electric wires, take down scaffolding and wrap rockwool insulation around steel pipelines. They bustle past in yellow and orange bibs, working 12-hour shifts against a backdrop of the Atlas Mountains. Harnesses with hammers and gloves strapped to their belts swing by their sides. Ubiquitous hard hats, safety shoes and ear plugs give the scene an air of theatrical camp.

For Hajar Lakhael, a 25-year-old environment and security manager from Meknes, rehearsals are almost over and the blockbuster production is nearly ready for action.

“We’ve done the construction and now we will see how these projects look when they start,” she says. “It is exactly like the preparation for a grand performance.”

A global audience will be watching with interest.
