Ingeteam has been awarded a further contract for the first commercial-scale solar thermal plant to be built in China. The company had already been awarded an initial contract for the basic engineering for this plant and has now won a further contract for the detailed engineering of the solar farm.

This is the first commercial-scale solar thermal plant in China, developed by CGN Delingha Solar Energy Co Ltd. The plant covers a total surface area of 250 hectares and is expected to start operating at the end of 2017. With a power output of 50MW, the plant stands out for its 7.5 hour, 1,300 MWt thermal energy storage capacity based on a molten salt tank system. The plant will operate for more than 5,000 hours, representing a generation of more than 210 GWh per annum and preventing the annual emission of 200,000 million tons of CO2 into the atmosphere.


With this new contract, Ingeteam is to develop the detailed engineering for the solar farm, including the process design, mechanics, electrics, instrumentation and control of the solar farm for the Beijing Shouhang IHW Resources Saving Technology Company. Ltd. The plant is located in the province of Qinghai, whose capital city is Xining, in the centre of China at a distance of 1,700 km from Peking. Due to the fact that the province is situated on a high plateau at an altitude of some 3,000 metres, surrounded by mountains, the climate is extreme, with little rainfall, extremely cold winters that can reach -27.9 ºC at the site, and very hot summers.

To date, China has built some small pilot solar thermal plants, directed at developing R&D, but has not commissioned any commercial plants. Ingeteam is therefore present in an expanding market, which has an extensive list of approved projects, forecasting a total power output of 1.35 GW.

The past 22 June, 2016, the European Consortium HYSOL celebrated the successful progress of their European Project in the Cobra T&I research centre at the Manchasol Concentrating Solar Power (CSP) plant, which has been carrying out during the last three years and will finish by the end of July.

The objective of the project has been to development of a prototype HYSOL, the key element for future solar capable of hybridising CSP technology with other energies (renewable and fossil) so as to be able to supply energy to the electrical network in a stable, firm and manageable way, independent of meteorological circumstances. Thanks to this prototype, the technology has been technically, economically and environmentally validated so that the HYSOL energy plants are ready to be implemented on a commercial scale.

International representatives of the CSP and renewable energy sector, such as investors, engineers, representatives of private institutions and equipment suppliers as well as national and international authority figures, all participated in the celebrated event. José Alfonso Nebrera (General Director of the ACS Industrial), Alberto R. Rocha (Director of Innovation and Project coordinator of the project HYSOL) and Lucía González Cuadrado (Technical coordinator of the project HYSOL) presented the technology developed by the consortium and the advances achieved using the new designed and developed pilot plant. At the same time, the event permitted the main stakeholders involved in the sector to interchange their impressions of the HYSOL technology in reference to its commercial potential and integration into the future hybrid CSP plants.

HYSOL is a project co-funded by the European Commission and led by the Spanish business ACS-COBRA. It counts on the participation of eight partners from European countries, including the Plataforma Solar de Almería (PSA-CIEMAT, Spain), la Universidad Politécnica de Madrid (UPM, Spain), ENEA (Italy), IDIE (Spain), AITESA (Spain), Danmarks Tekniske Universitet (Denmark) and SDLO-PRI (The Netherlands). By celebrating this event, the consortium puts an end to the phase of validating the technical, economical and environmental results of the theoretic models contrasted with the operating prototype.

The project HYSOL intended to implement an innovative way of CSP hybridisation with fossil (natural gas) or renewable (biogas, biomethane, combination gases) based fuels at a commercial level. This concept of hybridisation permits an optimal management of the electrical production with an elevated portion of solar energy (up to 74% in the studied locations), high conversion efficiency and an excellent flexibility in the operation to be achieved, which means a better economical, technical and environmental generation process from renewable sources.

The auxiliary fuels used in the plant are integrated with a CSP system by means of an aeroderivative gas turbine in a way so that the plant achieves electrical generation efficiency similar to combined cycles. The thermal energy of the escape gases produced by the gas turbine is recuperated thanks to HYSOL which takes advantage of this energy in order to heat the melted salts from the storage system which are sent directly to the vapour generator or are stored for later use when there is not enough solar resources to meet the demand.

As a conclusion, the achievement of the project HYSOL means a step forward in the development of CSP plants, opening up possibilities to promote new hybrid plants in order to overcome the barriers and constraints that the CSP plants currently have in terms of cost and management of their electrical production.

Enerray Morocco announces the progress in the construction of the first solar Plant, using CSP (Concentrating Solar Power) technology. The Plant is based in Ben Guerir, Green Energy Park site, 70 km from Marrakech.

Enneray has won the tender published by IRESEN (Institut de Recherche en Energie Solaire et en Energie Nouvelles) related to the realization of a 1 MW Plant with unique and innovative features for the Country: it’s a LFC (Linear Fresnel Concentrator) with flat mirrors and a total area of 11.400 m2, for a total amount of 6.000.000 EUR. The construction involves local companies for an amount of more than 20% of the total plant value, meaning a great integration between Italian and Moroccan Companies.

The project has been financed by OCP (Office Chérifien des Phosphates), world’s leading producer of phosphate rock and derivatives, and is aimed at studying the productivity and reliability for a future application in its mines.

Besides this Plant, Enerray has already installed a small PTC (Parabolic Trough Concentrator) with parabolic mirrors: this has been done for the solely purpose of analysis and research.

CSP-ORC System is usually applied in industrial applications and processes in order to generate heat and electricity.

CSP-LFC technology coverts solar radiation into thermal energy thanks to a concentrator made of flat reflective surfaces (Fresnel Mirrors) which focus sun’s rays on a receiver (Receiver Tube), in which there’s a special fluid for heat storage (Thermovector Fluid – in this case Diathermic Oil). Concentrator and Receiver create the Solar Collector, provided with a tracking system that allows it to follow the apparent motion of the sun.

The heat stored by the fluid is subsequently transferred to the ORC – technology part of the Plant (made of turbine, condenser, evaporator, alternator, etc.). This lets the thermic energy produced be converted in electric energy. ORC cycle has been settled with air condenser, in order to avoid the use of water and being particularly applicable in water-poor locations.

ORC system has been supplied by EXERGY, leader in the construction of patented radial-flow turbines to be applied in CSP Plants (and other kinds of plants) and having a fundamental advantage: management and maintenance is easy and can be done with a remote control, fully integrated in ORC Plant.

CSP-ORC system can be integrated with a Heat Storage System (Storage), which lets the Plant work even when it’s cloudy and during the night (i.e. even in low/no- light conditions).

The completion of the electromechanical part of the Plant is scheduled by the end of June 2016, whereas the Plant is planned to be operative in between August/September 2016.

On 5 February, Abengoa began the commercial operation of Khi Solar One, the first solar thermal tower technology plant in operation in Africa. Khi Solar One (50 MW) is furthermore Abengoa’s third commercial solar tower and its first outside Spain. The tower is located on a 600 hectare site close to Upington, in the Northern Cape Province. This project will contribute to South Africa’s goals of introducing up to 17,800 MW of renewable energy by 2030 and reducing its dependence on oil and natural gas.

This project is a public-private partnership awarded by the Department of Energy of South Africa and will supply clean and reliable electricity to Eskom, South Africa’s power utility, under a 20-year power purchase agreement. Abengoa, which has built and now operates and maintains the plant, owns 51% of the project; the Industrial Development Corporation (IDC), one of South Africa’s largest development finance institutions, holds 29%; and Khi Community Trust controls the remaining 20%.

Khi Solar One is a solar thermal super-heated tower technology plant, the first of its kind, with an installed capacity of 50 MW, capable of supplying 45,000 South African households with clean energy. The plant incorporates a storage system that enables production at maximum capacity for two hours without sun, thus bringing stability to electric production in the region. Read more…

Abengoa, the international company that applies innovative technology solutions for sustainability in the energy and environment sectors, together with the IDC and Khi Community Trust, has successfully completed 24 consecutive hours of commercial operation, solely powered by solar energy in its Khi Solar One plant. This plant is the first thermal solar tower plant in Africa and the first tower plant to achieve 24 hours of operation with solar energy.

The Khi Solar One plant is a one of a kind thermal solar tower that employs heated steam. It has a capacity of 50 MW, allowing it to supply clean energy to about 45,000 South African households. The plant began commercial operation on February 2nd, 2016.

The company has achieved this milestone thanks to the storage developed by Abengoa´s Research and Development team, the IDC and Khi Community Trust. The system accumulates steam at high temperatures and pressure, and allows for the generation of electricity after sunset. This system is capable of generating 50 MW for two hours after sunset. However, the fall in energy consumption at night allows for the operation of the plant below full power. Using this system, the operating unit of Abengoa, the IDC and Khi Community Trust in Khi Solar One have been able to produce electricity for 24 hours using only the steam generated by solar energy and meet energy needs. This milestone demonstrates the successful progress in the advancement of the operation of this innovative plant.

Khi Solar One is the result of significant research and development led by Abengoa. Specifically, the implementation of this large-scale project commercially, Abengoa previously operated a plant with a capacity of 5 MWt, located at the Solucar. Experience gained from the operation of the pilot plant allowed for the optimization of technology and served as a reference for project financing. All this work has resulted in the launch of a plant with increased efficiency, performance and production in terms of cost compared to previous models.

This project also offers numerous environmental and socioeconomic benefits. It eliminates the production of 183,000 tonnes of CO2 per year, providing the energy needed to meet the growing South African electricity demand in a sustainable manner. The plant has also promoted local economic development with the participation of a large number of local businesses. Similarly, the project’s part ownership by the Khi Community Trust ensures the continuity of investment in the community.

Along with this plant, Abengoa, IDC, PIC and KaXu Community Trust are currently in the process of building another 100 MW parabolic trough plant, Xina Solar One. This plant will employ a storage system that will allow the plant to operate for five hours without the sun. These projects demonstrate the commitment of Abengoa, IDC, PIC, Khi and Kaxu Community Trusts to the development of renewable energy in South Africa as part of the government strategy to collect up to 17,800 MW of renewable energy by 2030, thus reducing its dependence on oil and natural gas.

Abengoa, the international company that applies innovative technology solutions for sustainability in the energy and environment sectors, has sold to Masdar its share of Shams-1, the 100 MW solar thermal power plant developed by the Company in Abu Dhabi (United Arab Emirates). Abengoa previously had a stake in the plant as part of a joint venture together with the companies Total and Masdar.

This transaction is part of the disinvestment policy previously announced by Abengoa and is one of several transactions recently made. Additionally, Abengoa has completed the sale of former Abengoa offices in Madrid, located on Martinez Campos Street. The Company has also received offers for the 8,400 m2 building in Seville that once served as its headquarters, as well as for other real estate assets and pieces of land owned by the Company, located in various geographic regions.

As a whole, offers received by Abengoa for non-strategic assets exceed 100 million euros, including payment for Shams-1, the offices in Madrid and other non-strategic assets. The company expects to close further transactions in the coming days. These assets were included in the previously announced short term disinvestment plan.

These operations along with other disposals in advanced stages of negotiations plus necessary compromise negotiations with its various stakeholders (banks, bondholders, other financial creditors and suppliers), will allow the Company to advance towards viability.

Abengoa, advised by Alvarez & Marsal, is working on a viability plan that was presented to the Board of directors the last week of January 2016. In addition to continuing the disinvestment policy, the plan will allow the Company to simplify its structure, reduce costs and optimize its resources.

José Domínguez Abascal, Chairman of Abengoa, affirms that “income from the sale of assets will be used to cover expenses of the Company in order to face the negotiation process under Article 5 bis of the Spanish Insolvency Law”. “We are committed to transforming the business in order to adapt to the changing environment, while keeping characteristic aspects of the Company like cutting-edge technology and innovation which have defined Abengoa since its very beginning,” highlights Dominguez Abascal.

Today 4th of February 2016, the biggest Concentrated Solar Power Plant of the world, located in Ouarzazate, Morocco, is being inaugurated. The Solar Power Plant NOOR I in the south of Morocco, located 10 km from the city of Ouarzazate, has been inaugurated today with the presence of the King of Morocco, the Spanish Ministers Jose Manuel García Margallo y Jose Manuel Soria, and distinguished Spanish and Moroccan authorities.

The event was presided over by King Mohammed VI of Morocco, and brought together political representatives and executives from the constructor companies, among them the President of SENER’s engineering and construction group, Jorge Sendagorta, accompanied by the Project Manager of NOORo I at SENER, Verónica Rosello, and the representative of the Steering Committee of NOORo I, Santiago García, also from SENER; the Vice President of ACCIONA, Juan Ignacio Entrecanales, and the General Manager of the Industrial Department of ACCIONA Infrastructures, Ramón Jiménez; and the President of TSK, Sabino García, the General Manager of TSK, Francisco Martín, and the TSK Thermosolar Director, Andrés Cuesta.baja2

NOOR I, with a nominal capacity of 160 MW of electric power, and a capacity for energy storage in molten salts of 3 hours at maximum power, is the first solar energy project that maximizes the operating hours of the day, adapting to the peak hours of the Moroccan electricity market.

The construction of this plant is of vital importance for the sector within and outside the region. For the 160 MW it occupies 450 hectares and consists of 400 parabolic loops. In its construction some 1,400 workers have been mobilized, of which 70 per cent are local labor and the rest foreign technicians.

Saudí ACWA Power is the sponsor of this project. Aries Ingeniería y Sistemas has been the Owner´s Engineering of ACWA Power, and the construction in the form of the turnkey was conducted by a consortium of three Spanish companies Acciona, TSK and Sener. With this plant Aries is positioned as an engineering leader in the North African region and in solar power plants with energy storage.

SENER, ACCIONA and TSK make up the construction consortium with the turnkey contract, or EPC, for NOORo I, a high-efficiency modern power station. With 160 MWe of power and 3.5 hours of thermal storage it will supply 500 GWh of solar power per year, enough to meet the demands of 135,000 homes. NOORo I will avert annual emissions of 140,000 metric tons of CO2 into the atmosphere.baja3

In addition to NOORo I, SENER is a participant in the other two thermosolar phases of the project, NOORo II and NOORo III, in the same turnkey construction consortium. The three thermosolar plants are to provide a total of 510 MWe of power. All of them will be equipped with thermal storage systems, enabling them to continue to produce electricity in the absence of solar radiation. As a matter of fact, the time with the greatest demand for power in Morocco is nightfall, so the integration of these facilities in the Moroccan electricity system will be one of optimal efficiency. Altogether, they will avert annual emissions of 470,000 metric tons of CO2 into the atmosphere.

It is important to highlight that local input to the project is totaling as much as 30% of the construction work, as the constructor companies, including SENER, are strongly committed to the Ouarzazate community and to the Kingdom of Morocco; both workers and suppliers from the area are being employed, and have been ever since the start of the NOORo I first phase.

The high-profile construction in America market is crescent dune molten salt tower plant. Although it is said this plant was in grid and operation in the fourth quarter of 2015, it has not been officially announced. And it is also included in this statistics of new installed capacity of 2015.

In China, new increasing installed capacity of 2015 is 300kWth from Jiangsu Xin Chen, secondary reflection demonstration project. There is no other larger project in operation.


For Chinese market in 2015, the most notable is completion of declaration and audit of CSP   demonstration projects. It is estimated that new increasing installed capacity in China is expected to grow rapidly in 2016 ~ 2017 with an explosive growth by 2018.

The following plants are expected to be completed in 2016: Dunhuang molten salt tower plant with capacity 10 MW from SUNCAN Co., Ltd., Delingha molten salt tower reconstruction project with capacity 10 MW from SUPCON Co., Ltd, Zhangjiakou Fresnel demonstration projects with 15MWe (now upgrade to 20MWe) from Shenzhen Huaqiang Zhaoyang Co. Ltd., Dunhuang Fresnel molten salt plant with capacity 10 MW from Lanzhou Dacheng Technology Co., Ltd. In 2017, Delingha parabolic trough projects of China General Nuclear Power Group with capacity 50 MW and other large scale commercial CSP plants are expected to be put into operation. In 2018, most CSP demonstration projects about 1 GW are expected to be completed. At that time, China will become the hottest emerging market in global CSP market.

49.9 MW and thermal storage in a new generation plant


The OHL group’s industrial division is in its final phase of executing the construction of the Arenales CSP plant, and is currently in possession of the installation’s definitive start certificate. The CSP plant uses parabolic trough collector technology, has 49.9 MW of capacity, and is just waiting for the final jobs to be completed before coming on line by the end of this year.
