Why are battery storage options more suitable in Spain?

As a result, shorter duration storage options like batteries are more suitable in Spain. In Spain, over 50% of excess renewable energy occurs in periods where there is continuous excess for less than 12 hours i.e. a battery that chooses to charge on this energy would be able to discharge within 12 hours.

What is the market energy storage in Spain?

The market energy storage in Spain, particularly in relation to the BESS systems (Battery Energy Storage Systems), is undergoing a dynamic and accelerated evolution. This transformation is driven by the growing need to integrate renewable energy sources into the electricity grid, improve supply stability and optimize energy use.

Can battery storage systems be retrofitted in Spain?

The first solution is battery storage systems that enable peak shift, i.e. feeding electricity into the grid at times when the wholesale price is higher, usually before and after sunset. Fortunately, the retrofitting of battery storage systems in Spain is unproblematic from a regulatory perspective.

What is Spain's battery storage market?

Spain’s battery storage market is dominated by customer-sited systems. Utility-scale storage remains nascent. Currently, Spain’s storage market is mainly composed of small-scale batteries co-located with solar PV. Spain’s household electricity prices now stand at over EUR 0.30/kWh on average.

What is the first electric energy storage system in Spain?

In November 2019, Iberdrola España inaugurated the first electrical energy storage system with lithium-ion batteries for distribution networks in Spain.

How long does it take a battery to charge in Spain?

In Spain, over 50% of excess renewable energy occurs in periods where there is continuous excess for less than 12 hours i.e. a battery that chooses to charge on this energy would be able to discharge within 12 hours. This allows batteries to charge and generate within a day.
