LA AFRICANA SOLAR THERMAL POWER STATION

CIVIL ENGINEERING WORKS MANAGEMENT
Córdoba

The function of “La Africana” Solar Thermal Power Station is totransform solar energy into electricity by means of a solar land field of approximately 550,000m2 of cylindrical and parabolic shaped collectors, a 7 hours capacity thermic energy storing system of molten salt and a steam cycle of 49.9 MW of nominal power.

This is a state-of-the-art station of parabolic cylinders, where a set of parabolic shaped mirrors concentrate the thermal energy on a single axis. The axis heats a fluid which vaporizes water, creating steam that moves an electricity generating turbine.

The Station, located in Colonia de Fuente Palmera municipality, consists of the following systems: the solar field of parabolic-cylindrical collectors, the thermal storage system through salts, the HTF (High Thermical Fluid) system, the electric generator plant and the BOP (Balance of Plant) that works associated with a group of auxiliary installations that keeps the equipment in working order. The Station also includes the irreplaceable water collection and storage systems, and a set of industrial constructions where the various equipment is stored.

ACTIVE AND WELLNESS RESORT ENERGY SUSTAINABILITY ENGINEERING STUDIES

ESTEYCO developed the preliminary architectural design of an “Active & Wellness” concept holiday resort in 2016, with a special focus on sustainability, and more specifically architectural, implementation and energy sustainability.

On the energy sustainability side, ESTEYCO ENERGÍA carried out the following engineering work:

  • Electric and thermal load/consumption study of the traditional holiday resort sector of canary island.
  • Electrical and thermal consumption reduction estimation prior to energy efficiency measures.
  • Establishment of different generation / consumption scenario. Scenario 1: Resort energy system is 100% off grid with 100% of on site renewable energy supply. Scenario 2: Resort energy system is connected to the grid but with limited power supply from the grid. 60-80% of on site renewable energy supply.
  • Viability study of thermal energy supply by solar thermal panels, geothermal and heat pump .
  • Integration philosophy of thermal load management system using heat/cold accumulators.
  • Solar resource study and AEP estimation for the photovoltaic power plant.
  • Preliminary design of the photovoltaic power plant for each consumption scenario.
  • Viability study of the holiday resort electrical system with storage using a hydraulic storage pumping plant, battery banks and  emergency diesel generators
  • Integration philosophy of smart-grid management of the electrical system.

ELISA PROJECT – PROTOTYPE MARIO LUIS ROMERO TORRENT

EXPERIMENTAL OFFSHORE WIND TOWER 5 MW
PROYECT GRANTED BY H2020 FRAMEWORK
Arinaga and PLOCAN (Gran Canaria)

After 7 years of R&D, ESTEYCO is building the first prototype with ELISA project technology. This will be the first offshore wind substructure installed without the intervention of a heavy duty vessel, thanks to the telescopic tower and the self-floating structure, contributing significantly in the cost reduction of wind power in the marine environment.

ESTEYCO has developed the technology and is building the prototype with three partner companies, GAMESA, ALE Heavy-Lift and DEWI-UL, which are leaders in their respective fields. Installation is expected for May 2017 .

Another important characteristic of the technology is that the substructure is entirely made out of concrete, to reduce costs and enhance the durability in such an aggressive environment.

COLL DE PANISSOT WIND FARM

CLIENT: ALSTOM. 9 MW
DETAIL ENGINEERING DESIGN OF PRECAST CONCRETE TOWER AND FOUNDATION
ON SITE TECHNICAL ASSISTANCE DURING THE WORKS
Lleida (Spain)

Coll de Panissot Wind Farm is located in the province of Lleida in Spain.

ESTEYCO designed the 3 prototypes of 100 m precast concrete towers for the wind turbines ECO 110 3MW from ALSTOM, as well as its direct foundations also certified by DEWI-OCC.

Similarly, during the execution of the works, ESTEYCO carried out the on site Technical Assistance, supervising that the execution of the works corresponding to the provisions of the project

LES FORQUES WIND FARM

CLIENT: GAMESA. 4 MW
DETAIL ENGINEERING DESIGN OF PRECAST CONCRETE TOWER AND FOUNDATION
Tarragona (Spain)

Les Forques Wind Farm is located in the province of Tarragona, Spain. This wind farm has 2 precast concrete towers of 100m height which support  turbines type G90-2.0 MW, both designed by ESTEYCO.

In addition, ESTEYCO carried out the detailed engineering design of a foundation and the revision of the geotechnical report.

ESTEYCO also carried out the design of the tower-foundation connection with  prestressed bolts

TELWIND PROJECT

TECHNOLOGICAL DEVELOPMENT OF FLOATING OFFSHORE WIND SUBSTRUCTURE PROYECT GRANTED BY H2020 FRAMEWORK

ESTEYCO is pioneer in the development of a new technology of floating foundation for the offshore wind market, following the concepts developed in the GBS ELISA.

The floating foundation simplifies the transport and installation operations using the telescopic tower technology and allowing the entire assembly to take place at the port. It reduces the installation and operation costs, because it does not require heavy-lift vessels, very scarce and expensive, and is resistant to offshore environment.

The technology is completely scalable thanks to the use of concrete, with the possibility of supporting large turbines, even exceeding 10 MW.
