SENER, global engineering and technology group, together with its engineering, procurement and construction (EPC) partners, Emvelo and Cobra, announces that the Ilanga-1 Concentrated Solar Power (CSP) plant has been completed.

The EPC partners reached the certificate to initiate commercial operation of the turnkey solar thermal power plant project located at Karoshoek Solar Valley on 30 November 2018. This means the conclusion of construction, commissioning and testing of the 100 MWe Concentrated Solar Power plant. The plant has been handed over to the owner, Karoshoek Solar One (RF) Proprietary Limited. The plant will supply electricity to the national grid through Eskom, the South African electricity public utility.

“This is a historic moment in South Africa’s energy transition as another renewable energy powerplant that supplies clean, reliable, sustainable and dispatchable energy is successfully completed. We are particularly pleased that it was completed on time, within budget, within the required quality standards, in line with the contracted output performance and within acceptable safety standards. We are also pleased with the level of localization, BBBEE (Broad-Based Black Economic Empowerment), skills development and job creation that was achieved on the project. It is a clear indication of what is possible if the CSP industry can be nurtured and allowed to flourish in South Africa. SENER is proud of being a technology provider, engineering subcontractor and member of the EPC contractor on such a special project.” said Siyabonga Mbanjwa, Regional Managing Director for SENER Southern Africa.

“Ilanga 1 will provide on-demand power to South Africans for the next 20 years, in the same manner as conventional power generation projects. It has no fuel costs nor harmful emissions and has created employment for many people in the area of Upington. Ilanga 1 is an important step in South Africa’s energy future, procuring on-demand power from an efficient and accountable source with no resource risk and a controlled tariff. We as Grupo Cobra look forward to the continued growth of the local energy sector and will continue to provide world class development, construction and operations services to the South African market” said Jose Minguillon, CEO of Cobra South Africa.

“This is the first CSP plant in the history of the South African Renewable Energy Independent Power Producer Program (REIPPPP) that was conceived and developed by a 100% black owned South African entity. This demonstrates that Black Industrialists can lead in the development and execution of large renewable energy infrastructure projects. With a 550MWe pipeline of projects that are shovel ready at Karoshoek Solar Valley, the potential to localize, create jobs and provide business opportunities to new youth and women led SMMEs is colossal and what is required is for government to ensure that CSP remains a part of its energy mix policy and is included in the Draft IRP” said Pancho Ndebele, founder of Emvelo.

The joint venture between SENER, Cobra and Emvelo was appointed by Karoshoek Solar One (RF) Proprietary Limited to provide engineering, procurement and construction services as well as operation and maintenance for the project. The Ilanga-1 CSP plant, made up of 266 SENERtrough® loops, with approximately 870,000 square metres of curved mirrors, is equipped with a molten salt storage system (SENER proprietary technology) that allows 5 hours of thermal energy storage to extend the operational capacity of the plant to continue producing electricity in absence of solar radiation. This is a unique characteristic of CSP that radically changes the role of renewable sources in the global power supply. SENERtrough® collectors, a parabolic trough technology, are also specifically designed and patented by SENER, aimed at improving the efficiency of the plant.

In line with government’s four accords, emanating from the New Growth Path (NGP); namely basic education, skills development, local procurement and the green economy, approximately 1,500 jobs were created during the construction phase. Recently, a technical training course for 50 prospective employees at the plant, located in Karoshoek almost 30km east of Upington, were completed and further local socio-economic development was done by the EPC consortium, in the nearby communities located a stones throw away from the plant. It is estimated that Ilanga-1 will supply clean and dispatchable energy to around 100,000 homes and save 90,000 tons of CO2 per year over a period of 20 years.

Sener is about to start the final tests at Noor Ouarzazate III, after completing, last August, the first synchronization of the 150 MW Concentrated Solar Power (CSP) plant to the Moroccan grid. With these milestones, Sener starts the last phase before the plant’s commercial operation and final delivery to the client.

This plant is the second unit designed and built by SENER using its own central receiver tower and molten salt heat storage technology, and one of the first ones in the world to apply this configuration on a commercial scale. The high performance of this technology – the molten salt reaches higher temperatures than other CSP technologies, which maximizes thermodynamic efficiency – allows to manage the solar energy in absence of solar radiation and respond to the grid’s demand. This is a unique characteristic of CSP that radically changes the role of renewable sources in the global power supply.

In the Noor Ouarzazate III thermal power plant, Sener has been responsible for the plant’s conceptual and basic engineering, detail engineering and supplying equipment for the thermal storage system, engineering and construction of the solar field and the molten salt receiver, as well as the commissioning of the entire plant, which is expected to be delivered to the client by the end of 2018.

Noor Ouarzazate III is composed of a solar field of 7,400 heliostats HE54 (designed and patented by Sener), that point the Sun radiation towards a receiver located on the top of the tower, at a height of 250 m, thanks to the company’s highly accurate tracking system known as ‘solar tracker’. Sener has also been responsible for the 600+ MW high-powered receiver design and construction, in collaboration with Moroccan companies. Noor Ouarzazate III is also equipped with a molten salt storage system that allows the plant to keep producing electricity 7.5 hours without solar radiation and guarantees the dispatchability of the power plant. Along with all these key components, Sener has fully developed the integrated control system of the receiver and solar field.

Anas Raisuni, Sener Regional Managing Director in Morocco, commented: “Noor Ouarzate III synchronization is the last milestone before delivering the plant to ACWA and MASEN. With its visionary investment in solar power, MASEN has secured a clean, sustainable and manageable power supply for Morocco, while developing the national industry in a cutting-edge sector as CSP. We are very proud to have worked for these two entities (ACWA and MASEN), designing and building one of the most advanced solar thermal power plants of the world. Once operational, it will mark a turning point in
the CSP sector worldwide and will consolidate Sener as a leading engineering company and the most innovative one as a technology supplier for this sector.

Noor Ouarzazate III forms part of the Noor solar complex located in Morocco and managed by MASEN, and the largest solar complex in the world. In this complex, Sener forms part of the turnkey building consortium for the Noor Ouarzazate I and Noor Ouarzazate II plants – both of which use SENERtrough® parabolic trough technology – and Noor Ouarzazate III, with additional advanced innovations than those applied in the pioneer plant Gemasolar, which was designed and built by SENER and was the first plant in commercial operation with central receiver tower and molten salt heat storage technology in the world.

The United Nations Organization for Industrial Development (UNIDO) has commissioned CENER (Spain´s National Renewable Energy Centre) to carry out the accreditation and development of capabilities of a new solar thermal components laboratory in Egypt. This contract is a new international recognition for CENER, in this case in the field of solar thermal energy.

Last October, at NREA (New and Renewable Energy Authority) headquarters’ in Cairo was held the project kick-off meeting. In addition to two CENER researchers, Alberto García of Jalón and Xabier Olano, representatives of different entities, such as UNIDO, ENCPC (Egypt National Cleaner Production Center), EGAC (Egyptian Accreditation Council) and EOS (Egyptian Organization for Standardization and Quality) participated.

In particular, specialists from the Solar Thermal Energy Department of CENER will provide advice to achieve the accreditation of a solar thermal component testing laboratory, with the aim of subsequently being able to verify both the quality of the components manufactured in Egypt and of those from other countries. In addition, the CENER researchers will also be responsible for the technical training and capacity building of the personnel that will work in the aforementioned testing laboratory.

This contract is part of a global project called “Utilization of solar energy in industrial processes in the Egyptian industry”, which is funded by the Global Environment Facility (GEF) and implemented by UNIDO. Its main objective is to develop the market context for the promotion and local manufacture of solar thermal systems. The contract awarded to CENER focuses on one of the expected results of the project: the improvement of the manufacture, supply and distribution of the solar components and systems market. Ensuring that quality standards are met to guarantee the performance of solar systems over time

The international experience of Solar Thermal Energy Department is wide and varied. Evidence of this is the R & D projects in which it is currently working, six of which are financed by the European Commission. In addition, during this year almost 60 innovation contracts have been made with companies and private institutions. More than half have been signed with foreign companies, from countries such as China, the United Arab Emirates, Poland, Israel, the Netherlands, Germany, Austria, Italy, or France, among other. This important international presence is proof of the excellent research work carried out by the members of the solar thermal team of CENER over the last years.

Bookport concentrated solar power (CSP) plant in South Africa, built by Sener, Acciona and TSK, has set a new African record for the continuous, round-the-clock supply of electricity. Within the first month of commercial operation, the newly-inaugurated 50 MW Bokpoort CSP plant, produced electricity for a continuous period of 161 hours, equivalent to almost six days of continuous, full-load electricity – an African record.

CSP technology is considered an intermittent source of power which supplies electricity during daylight hours, when demand is highest. Nevertheless, Bokpoort’s design enables it to continue supplying electricity long after the sun has set thanks to a molten salt energy storage facility that can accumulate 9.3 hours of electricity production, the highest power storage facility on the African continent.

The Bokpoort CSP plant in the Northern Cape Province was built by a joint venture between Sener, Acciona, TSK and South Africa’s Crowie. They were awarded the EPC (Engineering, Procurement and Construction) project by the Saudi group ACWA Power, the plant’s owner and operator.

Round the clock electricity supply from a solar power plant is a significant milestone for South Africa and for the renewable industry as a whole, as it allows CSP technology to approximate the continuous power supply of conventional technologies such as hydroelectric, thermal or gas-fired power plants.Planta-Bokpoort2

In South Africa the country’s daily evening peak demand is from 5 pm to 9 pm and the newly introduced CSP Peak tariff means that developers are encouraged to have thermal storage capacity.

Bokpoort CSP has shown that due to the good design of the plant and the solar radiation available at the site, its 9.3 hours of thermal storage can easily be extended to allow round-the-clock continuous operations.

Nandu Bhula, CEO of Bokpoort CSP plant, declared: “Globally the biggest challenge of CSP has been its ability to produce energy consistently long after sunset. The performance of this plant is a clear indication that CSP technology can be used as a base-load capacity option in the same way as conventional power plants.”

CSP could supply as much as 12% of the world’s power needs by 2050, given the right conditions, according to a new report, Solar Thermal Electricity Global Outlook
2016, 4th Edition, released by Greenpeace International, SolarPACES and ESTELA (European Solar Thermal Electricity Association). It also shows how CSP could create millions of jobs. CSP is the key to achieving a world powered by 100% renewable energy by 2050. It also has the ability to harness the sun to provide round-theclock energy, even at night. CSP unlocks a future of emission-free energy in sun-belt countries around the globe.

The annual market volume for CSP hit US$1bn in 2009. While the installed capacity of CSP in 2006 was only 0.5 GW, it has increased ten-fold to almost 5 GW today. Projects currently under construction, mainly located in South Africa, India, the Middle East and Morocco, will add at least another 300 MW over the next two years.

The Solar Thermal Electricity Global Outlook 2016 modelled several future scenarios
for technology growth. The potential for CSP to meet global electricity demand is far greater. The analysis based on the Advanced scenario assumptions shows that concentrating solar power could meet up to 12% of the world’s projected power needs by 2050. Read more…
