en.Wedoany.com Reported - On July 13, Atlantica Sustainable Infrastructure has submitted applications in Spain to build two 50-megawatt (MW) battery energy storage systems at its concentrated solar power (CSP) plant in Extremadura. The company plans to hybridize the storage with its existing solar assets, and the permitting process has been formally initiated through a notice published in Spain's Official State Gazette (BOE).
These applications seek authorization to add batteries to these facilities, supplementing power generation by storing electricity. The BOE publication marks the start of formal administrative steps for the project, though the summary does not provide details on final approval, timeline, or capacity expansion specifics.
Atlantica's BOE notice reveals specifics of its 100MW CSP battery expansion project in the Extremadura region. Documents show the company is seeking to increase the flexibility and dispatchability of its CSP assets by coupling battery systems with existing solar generation.
By applying for two separate 50MW installations, the documents indicate the expansion is structured as discrete projects rather than a single consolidated site. This structure affects how permitting approvals, grid studies, and local infrastructure needs are assessed. The BOE process reflects that the battery additions are tied to specific generation facilities in Extremadura, meaning the storage is intended to operate in a coordinated hybrid mode with these CSP plants, rather than as standalone generation units.
These applications show Atlantica is seeking formal permits at the project level. Regulators must verify siting, technology integration, safety requirements, and impacts related to connecting storage equipment to the power system. The notice initiation step in the BOE means the proposal has entered formal review. During this phase, stakeholder comments, technical reviews, and grid and interface matters are typically addressed before any construction authorization is granted.
Each project is described as 50MW, totaling 100MW, confirming the scale of the planned storage expansion and indicating Atlantica's goal of adding meaningful system capacity beyond CSP generation output. The BOE application focuses on authorization to "add" batteries, pointing to an incremental upgrade model that enhances existing solar assets rather than replacing them, potentially aiming to improve energy shifting, peak support, and revenue potential. This BOE publication itself does not provide final investment or construction timelines; it merely records that the administrative process has been initiated, meaning this 100MW expansion still awaits subsequent regulatory outcomes.
Overall, these applications highlight that Atlantica's battery plans in Extremadura are designed as part of a CSP-plus-storage hybrid portfolio undergoing regulatory review. Grid connection, permitting compliance, and safety and siting verification will be core areas for regulators to examine next.
