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 will solar generation affect the power supply in Spain?

The prevalence of solar generation - with a strong daily pattern – will affect the capacity and type of power storage needed in Spain. This will be different to other European markets whose low carbon transition are wind & nuclear dominated.

Why does Spain have a shorter electricity supply than Great Britain?

Due to the different generation mix, the duration of excess or shortfall of electricity will be shorter in Spain than Great Britain (GB). This is primarily due to the daily generation profile of solar energy and the longer-term patterns in wind generation, which can last for weeks.

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.

Will Spain have a solar power system in 2030?

A power system heavily solar dependent in 2030 will require high levels of short duration battery storage installed in Spain in the near future. Spain is relatively isolated from other markets and only has limited import and export capacity to France, Portugal and Morocco.

Why does Spain's Bess pipeline lag compared to Italy's?

Spain’s BESS pipeline lags equivalent markets... Despite having a small install base, Italy’s current install base and 2030 pipeline is 6.8x that of Spain’s due to the presence of a Capacity Market and Firm Reserve (similar to FCR) tenders.
