La filial renovable de Endesa apenas usará 265 MW de acceso a red, por lo que MITECO ofrecerá los 937 MW no asignados a otros concursantes en orden de prelación.
Why it matters: Spanish grid capacity isn't actually full; it's being held hostage by utilities who over-promised and are now quietly retreating.
We are witnessing the death of the "land-grab" era in Spanish renewables. When Endesa (Enel) originally secured the 1.2GW Mudéjar node in Teruel, it was hailed as a masterstroke of Just Transition planning. Fast forward to today, and they are walking away from nearly 80% of that capacity. This isn't just a corporate pivot; it’s a market signal flashing red for anyone still betting on massive, unhedged solar-only developments in saturated regions like Aragon.
The Myth of the 'Winner-Takes-All' Auction
The problem with these mega-tenders is that they reward the most optimistic spreadsheets, not the most resilient engineering. Endesa likely looked at the current LCOE, the plummeting capture prices in Spain (often hitting €0/MWh during solar peaks), and the rising cost of capital, and realized that a 1.2GW build-out was a one-way ticket to a balance sheet nightmare. By only taking 265MW, they are cherry-picking the most viable sub-sections and leaving the rest for those further down the prelación list.
What This Means for the 'Next in Line'
If you are a developer like Forestalia, Naturgy, or EDP waiting in that queue, don't celebrate too quickly. The 937MW being handed back is "zombie capacity." To make it work where Endesa failed, you need a radically different approach: BESS integration is no longer optional. If you try to dump another gigawatt of pure PV into the Aragon grid without storage or a rock-solid industrial PPA, you’ll be facing the same cannibalization risks that scared off Enel’s bean counters.
This is a wake-up call for the Spanish market. Grid capacity is opening up, but only for those who can prove they won't just build more un-curtailable supply into an already drowning market.
