The end of June presented a less euphoric picture than the rest of the month. While the first few weeks had confirmed the progress of photovoltaics, hybridization, and energy storage, the final stretch acted as a filter: projects withdrawn by their promoters, applications rejected by the Administration, and a striking concentration of cancellations in Aragon .
The difference is significant. A withdrawal means the company decides to abandon the project or the process. A dismissal , on the other hand, implies an administrative rejection. In both cases, the result is the same for the capacity map: megawatts are dropped from the bidding process.
Enel Green Power reorganizes Teruel: more than 600 MW of hybrid projects eliminated and 385 MW that survive
The most relevant case of the week was Enel Green Power , Endesa 's renewable subsidiary, which starred in one of the largest portfolio cleanups published in the BOE during June.
The strongest group consists of four hybrid projects located in Teruel : La Masada , Itaca , El Tambor , and San Martín . These projects, which included accepted withdrawals , represented over 600 MW , a volume sufficient to alter the renewable energy landscape of Aragon.
This package also includes the accepted withdrawal of the La Plana wind farm module, with a capacity of 86.8 MW , also in Teruel . Furthermore, the Official State Gazette (BOE) recorded the rejection of the El Castillo wind farm module, with a capacity of 111.6 MW .
The business perspective points less to a general withdrawal and more to a selective portfolio restructuring . Enel is not abandoning Teruel: it is cleaning up projects, but maintaining other key assets.
In fact, in the same week it obtained the Prior Administrative Authorization for three relevant developments in the province: HB5-Regallo , with 213.094 MW photovoltaic ; HB2-La Plana , with 65.30 MW photovoltaic ; and the hybrid installation HB7-Pitarra , with 61.72 MW photovoltaic and 45.6 MW wind .
In total, the projects moving forward represent more than 385 MW with granted AAP (Authorization for Project Applications). The signal is clear: Enel is shedding assets from projects that are losing viability or priority, but protecting its positions around its strongest hubs in the Mudéjar Junction .
This move aligns with a broader trend in the Spanish market: large utilities are no longer proceeding blindly. In a context of price pressure, grid saturation, environmental requirements, and increased competition for permits, their portfolios are becoming more selective.
Other items that have fallen out of the BOE: storage, wind and solar.
The cuts at the end of June were not limited to Enel. The Official State Gazette (BOE) also recorded significant losses in storage, wind, and photovoltaic sectors.
In Huesca , Power Tarida, SL withdrew from the 100 MW Perdiguero Storage project. This is particularly significant because it comes in a month marked by the battery boom. Even in BESS, where investor appetite is growing, not all proposals pass the technical, financial, or strategic scrutiny.
In Asturias , Arena Green Power withdrew the Las Américas 12 Wind Farm project , with a capacity of 50.01 MW . The wind energy sector, already facing pressure from more complex permitting processes, local opposition, and longer development times, also showed signs of streamlining.

The list of rejected projects was even more diverse. Lavanda Desarrollos saw its 93 MW El Secarral photovoltaic plant in Alicante rejected. Amber Solar Power 's 60.72 MW ISF A Gudiña Solar project in Orense was also rejected. And Araste SPV 2021 's 86.8 MW Benavieja wind farm in Cantabria was also excluded.
Also included is the rejection of FV La Ladera , of 7 MW , associated with Trébol Desarrollos in Toledo .
The pattern is clear: June showed not only who is advancing, but also who is being left vulnerable. In a more mature market, the process ceases to be a race of volume and becomes a test of endurance.
Repsol balances the scales with Aguayo II: pumping returns to the center of flexibility
Amid the portfolio cleanup, Repsol Generación achieved the major administrative milestone of month-end closing.
On June 26 , the company simultaneously obtained the Prior Administrative Authorization , the Administrative Authorization for Construction and the Declaration of Public Utility for the Aguayo-Aguayo II reversible hydroelectric expansion in Cantabria .
The project includes 1,014 MW in turbines and 1,181 MW in pumping , a scale that makes it the jewel in the crown of the June BOE.
Its relevance lies not only in megawatts. Aguayo II reinforces a thesis that is gaining traction in the Spanish electricity system: long-term flexibility will be as strategic as new renewable generation.
While solar and wind power face greater vulnerability to low prices, grid inflows, and congestion, pumped hydro storage offers the capacity to displace energy, absorb surpluses, and provide backup power. In this context, Repsol gains a distinct advantage: it not only adds generation capacity but also management capabilities.
The comparison with the screening process for solar, wind, and hybrid projects is unavoidable. Where some developments are dropped from the pipeline due to a lack of viability, Aguayo II is progressing as structural infrastructure for a system with greater intermittency.
BESS continues to boom, but the market is already separating muscle from foam
The purge at the end of June does not erase the central trend of the month: storage gained weight in the BOE.
In the last week, the SPK Trujillo battery module in Cáceres , with 109.20 MW , stood out, having been published for public comment for AAP and AAC approvals . Progress was also made on the battery hybridization of the Iglesias Wind Farm , by Boreas Wind , in Burgos , with 30.3 MW , having already received AAP and AAC approvals .
These moves confirm that BESS no longer appears as a decorative accessory to the renewable pipeline, but as a piece of bankability, flexibility and value capture.
But the end of June also served as a warning. The energy storage frenzy doesn't immunize projects. Power Tarida 's withdrawal from its 100 MW project in Huesca shows that natural selection will also be at play in the battery sector: location, access, revenue model, permits, and corporate strategy will determine who moves forward and who is left behind in the cold, hard marble of the Official State Gazette (BOE).
