From El Prat to Cáceres the journey is long and a lot of energy is needed. The novelty is that from now on it will even be able to be stored.
Alter Enersun, an Andalusian company dedicated to promoting renewable electricity generation facilities, has developed and invested in a pioneering project in Spain: batteries that store photovoltaic energy on a large scale to supply it to the grid when it is not in use. can produce or to match demand and supply at specific times of the day.
To this end, it has entrusted its subsidiary, Alterna Energía, a firm based in El Prat de Llobregat, with the design, development and maintenance of this facility, in each of the Cáceres 2020 (51MWp, peak megawatts) and Cáceres plants. 2021 (53MWp) located in this Andalusian province.
Specifically, through this operation, 1 MW of electrical energy production will be added, apart from the start-up of this battery, which, unlike the smaller ones adopted for residential use, has a much higher price and complexity. This hybridization plant (this is its technical name) is one of the first in Spain with these characteristics.
Each one of the energy storage systems of each plant has five converters with a maximum active power of 200 kW, with a total of 1,000 kW. In addition, both the batteries and the converters will be governed by an intelligent controller (smart array controller) that will give instructions for the storage or discharge of the batteries depending on the park's generation, and will be connected to the control center of each one. of the plants.
Alterna Energía, which has been in this sector for 15 years, expects to bill around 32 million euros this year, a slight increase compared to the 29 of last year. Esther Morlanes, director of Alterna Energía, believes that storage is an essential technique in the energy transition process, since it allows solving various problems, such as the intermittency of electricity production from renewables, as well as always satisfying market demands , which can be more or less stressed depending on the seasons and times of day.
Alter Enersun, the parent company of Alterna Energía, has more than 150 rooftop and ground photovoltaic installations in Spain, Portugal and Mexico and is focused on large self-consumption and hydrogen projects.
