Port of spain frequency regulation energy storage

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.

Does energy storage provide frequency regulation?

This paper develops a three-step process to assess the resource-adequacy contribution of energy storage that provides frequency regulation. First, we use discretized stochastic dynamic optimization to derive decision policies that tradeoff between different energy-storage applications.

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.

Does Spain need storage?

Spain is relatively isolated from other markets and only has limited import and export capacity to France, Portugal and Morocco. This means that Spanish storage faces limited competition from cross-border flexibility. The Spanish Government have recognised the need for storage and set a target of 22GW by 2030.

How much does storage cost in Spain?

Namely, from 43 €/MWh (lower case) to 52.5 €/MWh and from 47 €/MWh (high case) to 56.5 €/MWh. This is comparable with the 67 €/MWh LCOH for the TES with retail charges. In Spain, subsidies for storage will be granted through four calls under the PERTE ERHA1 scheme.

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.
