PARIS, April 11 (Reuters) - Saudi Arabia, which is planning massive investment in renewable energy, hopes to export solar electricity to Europe in winter, when cooler temperatures reduce the need for air conditioning in the kingdom.
It would be viable for Saudi Arabia to export up to 10 gigawatts, the equivalent of 10 nuclear plants, via North Africa and Italy or Spain, Khalid Al Sulaiman, vice president for renewable energy at the King Abdullah City for Atomic and Renewable Energy (KACARE) told a conference in Paris.
“It is not a project, it is a potential. It has to be examined thoroughly by all,” Sulaiman told Reuters.
He said solar energy capacity in Saudi Arabia is “almost non-existent” at the moment, with only about 10 to 11 megawatts of capacity installed in the entire country.
But the kingdom has huge ambitions to build renewable and nuclear capacity as it tries to reduce domestic oil consumption.
The world’s top oil exporter said in February it aims to install 24 gigawatt of renewable power capacity by 2020 and 54 gigawatt by 2032, which would make Saudi Arabia one of the world’s main producers of renewable electricity.
Sulaiman said the first solar tenders will be offered this year.
A challenge for Saudi’s electricity sector is that during winter and parts of spring and fall, 45 percent of generation capacity sits idle. Cooling accounts for more than 50 percent of electricity demand in summer.
“We have thoroughly examined the potential for exporting electricity from dormant capacity during the off season to countries where peak demand coincides with our low demand season,” Sulaiman said.
He said studies show that the grid investment required to bring Saudi electricity to Europe would amount to between 15 to 20 percent of the total investment required to install some 20 gigawatt renewable generation capacity.
“Our study demonstrates that trading with the EU is economical, depending on the route chosen,” he said. Export capacity levels of 3, 5 and 10 gigawatt had been studied.
Transmission cables could go either via North Africa or via Turkey and Bulgaria, but the latter route is less advantageous because Bulgaria is a net exporter of electricity.
The Saudi electricity export plan is similar to the Desertec initiative, which aims to bring power to Europe from North Africa.
Sulaiman said that, unlike Desertec, KACARE’s plan would not require a third party to install generation capacity since KACARE would lead generation and connection investment.
He said he hoped European authorities would study the idea.
“If we could reduce the need to install generation capacity by, say, 10 to 20 percent through the ability to trade effectively, the savings would be tremendous,” Sulaiman said.
He said the project would take five to 10 years to implement but declined to give a cost estimate. Desertec has been estimated to cost up to 400 billion euros ($512 billion).
Jerome Pecresse, president renewable energy at French Alstom, which specialises in power grid equipment, said a Saudi Arabia-Europe link was technically feasible, provided financing is available.
Antoine Cahuzac, head of French utility EDF’s renewable energy unit, said public resistance to high-voltage lines will be an obstacle to all long-distance grid projects.
Saudi Arabia has equally ambitious plans to build 17 gigawatt of nuclear power capacity by 2032, and French utility EDF and reactor builder Areva hope to win a slice of the market.
EDF CEO Henri Proglio told the conference Saudi personnel are already in training in EDF facilities. (Editing by Grant McCool)
