Technical FAQs 3

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 can Spain transform its energy system into a climate-resilient country?

To ease financing, beneficiaries may request advance payments of up to 100% of the awarded aid, provided certain conditions are met. These efforts are part of a broader strategy to transform Spain’s energy system into one that is more flexible, robust, and climate-resilient.

What is long duration energy storage (LDEs)?

The 2023 NECP proposes a 173% increase (or 85 GW) in renewable capacity by 2030 from current capacities1; storage2 is expected to increase by 487%, or 15 GW from installed capacity. Long Duration Energy Storage (LDES) can ensure renewable energy is utilised in the system while decreasing reliance on CO2 emitting technologies
