Iberdrola installs its first solar plant with batteries in the middle of the ‘renewable turn’

Iberdrola has started up the first photovoltaic plant with batteries in Spain in Extremadura, the objective of which is to maximize the use of energy and promote an efficient integration of renewable energies in the electrical network. This 40 MW solar plant called Arañuelo III is part of the Campo Arañuelo photovoltaic complex, developed by Iberdrola and your technological partner Ingeteam in this region of Cáceres and formed, in addition, for the Arañuelo I and II plants, which have an installed capacity of 143 MW.

It is the first large-scale photovoltaic plant in Spain to incorporate a battery storage system of 3 MW of power and 9 MW of capacity. In the case of the Arañuelo I and II plants, the supply has been the usual one in a photovoltaic plant: photovoltaic inverters, transformation centers, PPC plant control system (power plant controller) and commissioning.

The novelty of the project is in Arañuelo III, since, in addition to all the above, for this plant Ingeteam has carried out a turnkey supply regarding the storage system. Thus, it has supplied the lithium-ion batteries, the integration of the batteries in 45-foot containers, the converters, the SCADA monitoring system, the civil works, the field assembly of the storage system and its subsequent start-up.

Ingeteam has also taken over the supply of digital protection system and control of the Arañuelo III substation. In addition to being the first large-scale solar plant to incorporate batteries in Spain, this project has an additional novelty, which is that the battery storage system has been included within the photovoltaic plant in a distributed manner and following a DC- configuration. Coupling or coupling in direct current.

In this mode, the batteries are installed inside the solar field and the battery converters share the direct current connection with the photovoltaic inverters, which has different technical advantages. The Campo Arañuelo complex already generates clean energy to supply a population equivalent to 65,000 homes per year and will prevent the emission into the atmosphere of 41,000 tons of CO 2 per year.
