The Official State Gazette (BOE) of Spain in June published a renewable energy processing map of 4,226.14 MW between photovoltaics, wind power and storage, excluding only those files with withdrawal or rejection.
Of the total, 2,605.59 MW correspond to photovoltaic technology , 969.67 MW to BESS storage , and 596.55 MW to wind power . In addition, there are 54.33 MW of hybrid wind-photovoltaic capacity without a specific technological breakdown , corresponding to the Cabeza Morena project.
June's activity confirms the strong presence of photovoltaic solar energy, but also the advancement of BESS as a strategic vector for new developments. In this context, Solaria and Iberdrola stand out as two of the leading players this month, both in terms of volume and technological positioning.
In the case of Solaria , the company's prominence comes from two avenues. On the one hand, the Helena Solar cluster is once again showing traction in Castilla-La Mancha, with photovoltaic stages III, IV, V and VI under Declaration of Public Utility, totaling 168.41 MW in Toledo.
This group is complemented by the hybridization strategy. Solaria is linked to projects such as Armus, with 20 MW BESS, 35 MW wind and 49.88 MW photovoltaics in Palencia; Castor, with 19.99 MW BESS and 49.99 MW photovoltaics in Toledo; and Mimas, Titán and Dione, with 63 MW wind in Guadalajara.
On Iberdrola 's side, the significant increase is explained by its Otero and Aceca mega-plants. The former, located in Segovia, contributes 431.64 MW of photovoltaic capacity , while FV Aceca adds 347.51 MW in Toledo. Between the two, the company adds 779.15 MW , nearly 800 MW across two projects, a volume that places it squarely on the regulatory radar for June.
The multinational also appears with Sierra del Romeral, which combines 31.45 MW of wind power and 30.93 MW of photovoltaics in Villacañas, and with Cofrentes I, of 154.66 MW of photovoltaics , published with prior occupation records in Valencia.
Hybridization and BESS: storage ceases to be an accessory in June
Energy storage has emerged as one of the major trends of the month. It is no longer limited to one-off projects or auxiliary solutions: the Official State Gazette (BOE) shows both large stand-alone batteries and hybrid systems combined with photovoltaics and wind power.

The first group includes notable projects by Rolwind Renovables , especially ST Palmosilla, with 200 MW of stand-alone storage in Tarifa, and ST Cerrillo, with 77.6 MW in Álora. Also included are projects such as Orcoyen Almacena, by Abo Wind España , with 73.6 MW in Navarra, and BESS Lagerung, by A Green Message / Matrix Renewables , with 101.8 MW in Girona.
The second group comprises hybrid models. X-Elio Energy is processing the Pacheco Modules project, with 105 MW BESS and 98.4 MW of photovoltaics in Cartagena. Opdenergy , through Planta Solar OPDE 51 and 52, is moving forward with Belinchón 1 and 2, which adds 53.48 MW BESS and 96.23 MW of photovoltaics in Cuenca. FRV , together with Abdul Latif Jameel Energy , is presenting La Solanilla, which combines 42.77 MW of photovoltaics and 17.5 MW BESS , with a usable storage capacity of 70 MWh in a four-hour system.
Also noteworthy is Tagus 2 HBESS, by KHONS SUN POWER , with 176.44 MW BESS and 224.40 MW of photovoltaics in Toledo. Its total capacity of 400.84 MW makes it one of the largest hybrid projects of the month and reinforces Castilla-La Mancha's role as a regulatory testing ground for large-scale storage projects.
Castilla-La Mancha and Andalusia dominate the June map
The territorial distribution confirms a very marked concentration. Castilla-La Mancha has the largest volume of applications, with around 1,674.91 MW processed between Toledo, Cuenca and Albacete.
This area is home to projects from Solaria , Iberdrola , KHONS SUN POWER , Elawan Energy , Opdenergy , Aquila Clean Energy , Repsol , Ignis and Finerge , among other players.
Toledo is positioning itself as one of the month's epicenters. Helena Solar, Castor, Tagus 2 HBESS, Sierra del Romeral, FV Aceca, Autoconsumo Refino, and Mulhacén Solar are all featured there. Cuenca is also gaining ground with Iniesta, El Casarejo, and Belinchón 1 and 2, while Albacete adds Cabeza Morena and El Cuco.
Andalusia also occupies a central position, with approximately 754.98 MW processed. Cádiz is home to projects such as ST Palmosilla, FV Sancho, and Hermod, while Huelva includes the La Puebla 3 and La Puebla 4 developments by Jinko Greenfield Spain . Málaga, for its part, appears with ST Cerrillo and the Ronda Colectora PV substation.
Castilla y León also maintains a significant position, driven especially by Otero, owned by Iberdrola , and by projects from Capital Energy , Acciona , Grupo Cobra , and Solaria . Extremadura, the Region of Murcia, Aragon, Catalonia, Navarre, the Valencian Community, and the Community of Madrid complete a more distributed map, although with a lower MW density than the major centers of Castilla-La Mancha and Andalusia.
Overall, the 4,226.14 MW published during June reflect a growth dynamic that continues to advance despite administrative and territorial pressures.
