In addition to Noor Ouarzazate I, SENER is a participant in the other two thermosolar phases of the project, Noor Ouarzazate II and Noor Ouarzazate III, in the same turnkey construction consortium. The three thermosolar plants are to provide a total of 510 MWe of power. All of them 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.

  • Proyect data:
  • Total reflective area: 1,308,000 m2.
  • Number of SCA/loops: 1,600/400 (SENERtrough®).
  • Surface area of the solar field: 400 Ha.
  • Nominal solar field thermal output: 680 MWt.
  • Thermal storage capacity: 1,490 MWht.
  • Turbine power capacity: 160 MWe.
  • Contract type: EPC.
  • How it works
  • SENERtrough® collectors
    Solar radiation beams on the SENERtrough® collectors which concentrate said radiation in the central tube through which fluid heated to very high temperatures circulates. This fluid, generically called HTF (Heat Transfer Fluid), is in this case similar to oil in composition.
  • Steam generator system
    The HTF is pumped through the piping system to the steam generator, where it transfers its heat to vaporize water.
  • Steam turbine
    The steam produced under high pressure is used to move the turbine. The turbine is connected to an alternator that generates electric power.
  • Condenser
    The steam released from the turbine condenses into water that is again incorporated into the cycle.
  • Cooling tower
    The cooling tower provides the cooling needed to condense the steam turbine exhaust.
  • Heat exchanger
    When there is excess thermal energy in the solar field, it is stored. This is done by diverting some of the heated HTF to the exchanger, where it comes into contact with the salts, transferring its heat to them.
  • Thermal storage system
    To fill up the storage system, cold salt is pumped from the cold-salt tank to the heat exchanger, where the HTF heats it. The salts are then stored in the hot-salt tank.
    During discharge, the stored hot salt is pumped to the same heat exchanger to heat the HTF and continue generating electricity even during periods when there is no solar radiation.

Dioriga Gas tasked us with the conceptual design engineering and FEED (front-end engineering design) for a floating storage and regasification unit (FSRU) as part of a liquefied natural gas import terminal, along with the development of marine infrastructure and an onshore natural gas plant. At SENER, we executed an integrated project that encompassed marine infrastructure (including a jetty and trestle) and the construction of a natural gas plant.

At SENER, we performed the engineering required for the FEED, focusing on confirming technical, economic, environmental, and safety feasibility. We designed the FSRU to be adaptable, enabling it to function as both a gas carrier and a regasification unit. Our goal was to create an FSRU-type vessel capable of transporting LNG while also providing regasification capacity to deliver natural gas to the onshore network.

Trabajamos para la diversificación y autonomía energética

Ventajas 

  • El diseño permite la operación como buque de transporte de LNG (LNGC) y como Unidad Flotante de Almacenamiento y Regasificación (FSRU) 
  • El diseño puede abastecer: gas a alta presión para la red de distribución terrestre, por medio de un jetty y de un trestle; además de la planta onshore; gas licuado para cargar camiones; y bunkering de GNL con la modalidad STS (ship to ship) a buques gaseros de pequeña escala. 
  • Posee 4 trenes de vaporización con capacidad de 125 MMSCFD a 12 MPa cada uno. 
  • Los FSRU de SENER son plantas de configuración flexible y modular, que se ofrecen en diferentes configuraciones para adaptarse a las demandas del cliente.

EZ Solar Field is an integral digital solution for the optimal operations management and maintenance of solar fields, focusing on solar thermal power plants that use parabolic trough collectors.

Unlike other tools, it covers the entire cycle from the capture of data to the confirmation of the technician’s work order in the field and the analysis of its completion. 

This software, developed by Sener, captures the data via an automated process that collates the data exported from the monitoring system. Its data model integrates 1000 SCAs, its instrumentation, the main flow rates to its field, the meteorology and the field alarms. An algorithm analyses them and automatically generates corrective actions in the form of work orders, with prioritization and approval workflows included. 

With EZ Solar Field, you can check the results online through interactive dashboards for supervisors and a mobile app for field operators. Thanks to its analysis capabilities, you can radically reduce the time invested in preventive tasks that relate to the calibration and balancing of loops, with an overview of which part of the field is deteriorating the most. 

It optimizes the capacity of the maintenance teams for fields of any size, with a reduction of up to 20% of the OpEx and a yield increase of up to 8%.
