Spain will hold its next renewable energy auction on 25 October 2022 to allocate 520 MW of renewable capacity.
The Ministry for Ecological Transition reserved 140 MW for distributed solar PV projects of up to 5 MW, and 380 MW for concentrated solar power (CSP), biomass-based and tech-neutral schemes. The 380 MW are further split between 220 MW for CSP, 140 MW for biomass and 20 MW for other renewables technologies (biogas, bioliquids, hydro or tidal power).
The upcoming auction will be Spain’s third to employ a pay-as-bid remuneration model as the form of regulatory support. The first two were for variable renewables, wind and solar PV, and the ministry says that this time, firm renewables need to be incorporated in line with Spain’s 2021-2030 national energy and climate plan (NECP).
For the bidders, this means that their CSP projects must have six hours of energy storage to be eligible to participate. CSP can also be hybridised with biomass, biogas, bioliquids and solar PV, if the PV component does not exceed 10% of the CSP capacity.
