A consortium of clean energy developers has applied for permission to build a gigantic solar power plant on the edge of the Sahara desert, which will be linked to Europe by a number of undersea cables and could power over 5 million homes.
TuNur’s planned project in Tunisia hopes to tap into the Sahara desert’s vast potential to provide solar power. Its request to the Tunisian energy ministry envisages a facility in the southwest of the country that will produce 4.5GW of power.
Chief Executive Kevin Sara claimed that an initial 250MW could be up and running, powering Europe via an interconnector with Malta, by 2020. It would mean an extra 1,000GWh of clean power a year being made available to the European grid.
Italy and Malta’s energy grids are already connected via a 95km link that came online in 2015.
Even this initial phase of development, which would cost an estimated €1.6bn, would be one of the largest facilities of its kind in the world.
The TuNur project will hope to avoid the fate of the similarly ambitious DESERTEC initiative, which was scuppered in 2013 after its main backers fell out. The partnership began in 2009 with the aim of promoting a €400bn project that would have provided 15% of Europe’s power by 2050.
Sara insisted that TuNur is better prepared for the challenges ahead, claiming that DESERTEC was “a big consortium of companies looking for business opportunities, but no plan”.
Similar to DESERTEC, TuNur plans to exploit Tunisia’s abundant sunshine and large amount of land that is unsuitable for agriculture. The firm’s most ambitious version of its scheme is a solar facility that covers 25,000 hectares, an area nearly the size of Malta.
The second stage of the plan is to construct Concentrated Solar Power (CSP) towers with a capacity of 2.25GW, which would be connected to Italy, just south of Rome, via another cable that would deliver 9,000GWh per year.
This second 600km cable has been under development for a number of years and is currently being evaluated as a project of common interest by the EU. A third cable that will link Tunisia with France and more towers that would bring capacity up to 4.5GW are also planned.
TuNur claimed in its request to the energy ministry that the power generated will be enough to power over 5 million homes or fuel over 7 million electric vehicles.
Europe currently has about 100GW of solar photovoltaic power capacity, the bloc’s sixth largest source after natural gas, wind, coal, large hydro and nuclear.
