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.

Engineering and technology company Sener is putting into operation, on a multi-phase basis, the different components of the Noor Ouarzazate III CSP plant. This plant is the second CSP plant 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.

Sener recently carried out the start up of the solar receiver, pointing the heliostats towards the receiver located on the top of the tower, at a height of 250 m, to pre-heat it to 320ºC.

Sener has also been responsible for the receiver technology design and construction, applying its know-how from the aeronautical sector. This 600+ MW high-powered receiver has been developed in collaboration with Moroccan companies and, once in operation, it will enable the plant to reach a gross production of 150 MW and 7.5 hours of heat storage. Similarly, Sener has fully developed another key element for this type of installation: the integrated control system of the receiver and solar field.
As a preliminary step in the receiver start-up, Sener has completed the functional tests in the solar field, comprising 7,400 heliostats HE54, designed and patented by the company. This model (the HE54) incorporates improvements such as a larger reflective surface (178.5 sqm compared to the 115.7 sqm of the Gemasolar heliostats) and a highly accurate tracking system known as ‘solar tracker’, which uses Sener space technology.

Once the receiver pre-heating tests currently underway are completed, the next step in the commissioning phase will be to circulate the molten salt throughout the receiver to heat them to the daily commercial operation temperature (550º C). This milestone will be accomplished in the coming weeks. The last phase will consist in generating steam using the heat captured from the mentioned molten salts.

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 located in Seville (Spain), in commercial operation since 2011, which was designed and built by Sener.

In the Noor Ouarzazate III thermal power plant, Sener is 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. The plant’s delivery to the client is planned for the last quarter of 2018.

The Nordex Group has opened a plant in the North Brazilian state of Brazil Piaui for the production of concrete towers. The plant is to produce the 65 towers required for the Lagoa do Barro wind farm, which Nordex will be installing in the near future.

It marks one of the first major investments in this state’s wind power industry. Large parts of the plant were originally used at a former facility in the south of Brazil and transported in heavy-duty loads to Lagoa do Barro City in a good 300 trips.

With this step, Nordex is able to optimize the construction costs of the wind farm and complete construction work with minimum environmental impact. “We also wanted to ensure that the local population directly benefits from the project. Tower production alone will provide work for some 300 people,” said David Lobo, Head of Sales Brazil, who is managing the project for the Nordex Group.
