Andalusia has taken a decisive step to accelerate the deployment of energy storage. Through the twelfth additional provision of Law 4/2025, the regional government of Junta de Andalucía has approved an urgent permitting procedure for hybridised energy storage projects that do not require an environmental impact assessment.
The new framework halves administrative deadlines for both project authorisation and related public consultation processes, as well as for referrals to relevant authorities.
“Urgent processing will apply to administrative authorisation procedures and to the approval of execution projects for hybridised electrochemical storage,” the legal text states.
Under the new rules, project developers may submit the authorisation request and the execution project simultaneously, together with documentation proving that the initiative is exempt from environmental assessment. The procedure will be governed by Article 96 of Royal Decree 1955/2000, enabling faster processing for projects that meet the established criteria.
This simplified regime is designed to speed up the commissioning of energy storage systems—a critical technology for ensuring grid stability and facilitating the large-scale integration of renewable energy such as solar PV and wind power.
The administrative acceleration responds to a context in which Andalusia already leads Spain’s energy storage development. According to the final resolution of the EU-funded FEDER programme, the region secured €354.5 million for 32 projects totalling 3,529 MWh, accounting for more than 43% of the total budget awarded nationwide by IDAE.
This momentum is particularly significant given that, between 2022 and 2025, Spain processed more than 43 GW of storage projects undergoing environmental evaluation. Within this pipeline, Andalusia represents a substantial share, with over 800 MW of storage capacity under development, including flagship initiatives such as the 77.6 MW “ST Cerrillo” project by Rolwind in Málaga.
Andalusia is also Spain’s leading region for solar PV deployment, with more than 11.35 GW of installed capacity, representing 23.5% of the national total. In 2025 alone, the region added 1,961 MW of new solar capacity.
This rapid expansion makes storage capacity essential to manage surplus generation, reduce curtailment and optimise grid operation. With this decree, the Andalusian government sends a clear signal to the market: regulatory bottlenecks will be removed to accelerate strategically important projects across the renewable energy ecosystem.
The announcement comes ahead of the Future Energy Summit Iberia, to be held in Madrid on 12 February, where Manuel Larrasa Rodríguez, Secretary General for Energy of the Andalusian government, is expected to discuss regional regulation and storage challenges alongside officials from the Canary Islands and Castilla y León.
With this measure, Andalusia consolidates its leadership in Spain’s energy transition by promoting an efficient, proactive regulatory framework that incentivises hybrid energy storage deployment. The objective is clear: attract further investment, accelerate renewable energy integration and reinforce the resilience of the future power system.
“This simplification seeks to guarantee the security and stability of the electricity system and to facilitate greater integration of renewable energy,” Law 4/2025 concludes.
