The Spanish photovoltaic market continues to grow rapidly, with 57 projects advancing in the permitting process between the end of January and the first days of April 2026 , totaling more than 3.7 GW , according to data from the Official State Gazette (BOE) analyzed by this publication. This volume confirms the strength of the pipeline, although it also reveals an increasingly competitive landscape conditioned by structural limitations in grid capacity.
The market movement is driven by a clear group of developers , including Iberdrola, Ignis, Statkraft, Cobra, Verbund, Jinko Solar, X-ELIO and Solaria , among others.
Iberdrola has positioned itself as the most active player, with 558.4 MW of projects under development across three plants in Navarre, the Valencian Community, and the Basque Country . The utility company is consolidating its presence with large-scale projects distributed across various regions, reinforcing its strategy in the solar sector.
Behind them, Statkraft reaches 253.8 MW from the Arada Solar (139.8 MW) plant in Castellón and FV Calzadilla (114 MW) in Cáceres, despite having suffered the rejection of one of the largest projects of the period (300 MW in Toledo), while Jinko Solar adds 209 MW , demonstrating the growing weight of international players in the Spanish market.
Verbund also stands out with 212.5 MW , followed by Ignis with 187.3 MW , a company that continues to expand its pipeline with multiple parallel initiatives. In a second tier are Solaria (140 MW), Sinerba (121.8 MW), Q Energy (103.6 MW), and OPD Energy (100 MW) , consolidating a group of developers with strong activity at various stages of the development process.
This business map reflects a competitive but concentrated market , where a limited number of actors account for a significant part of the volume in process, supported by multiple corporate structures to optimize project development.
Another key point is that hybridization is emerging as one of the clearest strategies for unlocking capacity and optimizing existing assets, with several specific cases identified in the
period analyzed.
On the one hand, hybridization projects with existing wind farms are being observed , allowing for the use of already granted grid connection points. Among these, the solar plant linked to the Mamut wind farm in Granada stands out, with a capacity of approximately 0.8 MW , designed to complement existing wind power generation. Similarly, the Teso Santo project in Salamanca (43.2 MW photovoltaic) is explicitly planned as a hybridization with a 50 MW wind farm, reinforcing the trend towards maximizing existing infrastructure.
Also included are initiatives such as Surco Solar in Zamora (50 MW) , associated with an existing wind farm, and developments in Cádiz (Jerez, 42.5 MW) and Zaragoza (El Tollo and Picador, 45 MW each) , which incorporate hybrid schemes. In the latter case, an additional component is introduced: hybridization with storage , marking a further step in the evolution of these models.

Integration with storage is beginning to gain ground , although it is still in its early stages in the analyzed pipeline. The clearest example is the Picador project in Aragon , which includes hybrid solar with storage systems , allowing for better management of production and adaptation to system demand.
In parallel, multiple hybridization processes are also identified in early stages of environmental processing , suggesting that this trend will continue to grow in the coming months as a direct response to network limitations.
This move is not isolated, but rather aligns with a broader trend in the Spanish market, where, as reflected in the recent analysis on storage by Energía Estratégica, 61 projects for 2420.1 MW of storage were processed during the first quarter of the year.
In this scenario, the combination of photovoltaics and batteries emerges as a key solution to capture value, reduce waste and enable new connection points, especially in areas with high renewable penetration.
Where are the projects located and what stage are they at?
The progress of these projects is concentrated mainly in Castile and León, Andalusia, and Extremadura , regions that continue to attract the majority of investment due to their solar resources, available land, and historical capacity for renewable energy development. Provinces such as Valladolid, Málaga, Badajoz, and Seville stand out for the frequency of these initiatives.
In administrative terms, the pipeline shows a significant degree of maturity , with projects progressing through the Prior Administrative Authorization (AAP), Construction Authorization (AAC), Environmental Impact Statements (DIA) , and public utility processes. Furthermore, the presence of multiple files in the expropriation phase indicates that several developments are nearing completion.
However, pipeline growth faces a critical structural challenge: the saturation of electricity grids . The concentration of projects at certain evacuation nodes is creating bottlenecks that affect both processing times and the viability of new initiatives .
This context helps to explain the rejections recorded in the period, which reach 415 MW , including relevant projects that failed to pass the authorization phase.
