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.

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.

How does Spain's pumped hydro energy storage compete with Bess?

Spain's pumped hydro energy storage competes directly against BESS, limiting the battery storage opportunity in wholesale markets. 3. Missing ancillary markets Unlike Great Britain or Texas, Spain never created ancillary service markets that net-zero systems need:

Does Spain have a storage market?

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. In addition, Spain’s reliance on fossil gas has increased price volatility in recent years.16,17,18,19

What is a battery energy storage system?

Storage batteries of the Arañuelo III photovoltaic plant. Battery Energy Storage Systems (BESS) are one of the latest solutions for storing energy for later use. The batteries have a mechanism that allows energy to flow in both directions to charge and discharge the batteries.

Why are Spanish wholesale markets opening up a battery market?

Spanish wholesale markets have offered increasing revenues due to recent price volatility which rewards BESS through power trading. However, sustained investment in batteries will be supported by fully opening up markets.
