Spain is experiencing an obvious and costly energy paradox. While the country breaks renewable generation recordsits electrical system suffers an administrative “thrombosis” that threatens to stop reindustrialization. The problem is that the system works like a broken bridge: clean energy is born in the so-called “emptied Spain”, but there are not enough cables to take it to the cities and factories where consumption is concentrated.
The panic in the sector reached its peak when the National Markets and Competition Commission (CNMC) was forced to postpone three months (from February 2 to May 4, 2026) the publication of the access capacity maps after a critical alert from Red Eléctrica: under the new security criteria, approximately 90% of the network nodes would appear in “red”, that is, with zero capacity. However, the network is not physically collapsed, but administratively “full” and underutilized in practice. To solve this funnel, the CNMC has put on the table a master plan that will change the rules of the game: flexible access permissions.
The perfect storm. Getting to this point has not been the result of a single mistake, but rather a cocktail of bureaucratic slowness, territorial imbalances and speculation. As we have already advanced in Xataka, There is a huge gap between administrative times and physical execution: building a substation barely requires a year of work, but its prior processing can take between three and six years. Added to this is that we have installed windmills and solar panels where there is land and resources, but demand is growing in metropolitan areas that do not have sufficient infrastructure, leaving 83.4% of distribution nodes saturated currents.
The consequences on the street are devastating. Last year only 12% of connection requests for new urban developments were granted, which, according to the Asprima employers’ associationputs the construction of 350,000 homes at risk due to the simple lack of electrical power. And in the midst of the chaos, the bubble: there are access requests for 67,100 MW (half of all the installed power in the country), which makes the regulator suspect the existence of “ghost” projects that hoard nodes only to resell the permits.
The end of the binary model. Until now, the electrical system operated under a binary principle: either they gave you firm access, 100% guaranteed, or they denied it. However, as he noted on his social networks the Secretary of State for Energy, Joan Groizard, the current network is underused; In fact, a “smaller” network in the past supported demand peaks much higher than today.
This is where the regulatory revolution comes in. The CNMC proposal breaks with the resounding “no” and establishes that, if there is residual capacity at certain times of the day or year, it can be shared. Flexible access capability assumes that supply will not be guaranteed at all hours of the year, maximizing the use of existing infrastructure without immediately resorting to massive investments that citizens would end up paying for.
The four ways of flexibility. To articulate this new paradigm, the supporting report and the proposed resolution of the CNMC define four types of permits Flexible access, adapted to different needs:
- Permission Type 0 (Fixed pattern in Distribution): Applies to installations connected to any voltage level in the distribution network. It allows energy to be consumed following a fixed time pattern (for example, from 00:00 to 07:59 and from 11:00 to 17:59), which represents at least 62.5% of the hours of the year. Outside of these ranges, if the installation consumes power, the network manager (GRD) can disconnect it remotely without prior notice. It is ideal for those who can plan their production.
- Type 1 Permit (Remote disconnection due to contingency N-1): Designed for distribution installations with voltage greater than 36 kV. The installation meets the requirements under normal conditions (with an expected consumption of 90% of the year), but agrees to be disconnected remotely and without prior notice if any element fails in the substation itself to which it is connected.
- Type 2 Permit (Dynamic Instructions in Distribution): For voltages greater than 36 kV and powers greater than 1 MW. It is the most technologically advanced, the installation must be able to receive dynamic instructions from the GRD to reduce its load, whether scheduled the day before or in real time. Response times are critical: less than 30 minutes if it is preventive, or less than 3 minutes (immediate) if it is corrective. If you disobey, you will be disconnected. This model will come into force from January 1, 2028.
- Type 3 Permit (Transmission with automatic reduction): Aimed at demand installations of more than 1 MW connected directly to the transmission network. These facilities are required to participate in the Automatic Power Reduction System (SRAP). In the event of a security alert from the electrical system, the operator (OS) will send a signal and the installation must reduce the power associated with its flexible access to zero effectively and immediately.
Winners, exceptions and the bill. This regulatory change has clear winners and some red lines. Storage facilities in demand mode are the perfect candidates, since, by law, they have no guarantee of supply and will have 7 months to request the modification of their permits. At the opposite extreme, the CNMC explicitly prohibits granting these accesses to essential supplies (such as hospitals), to demands that do not support 24 hours without a network, and to collective projects such as urban plans.
Modernizing the network to support this “reinforced mode” of digitalized operation will have a direct economic impact. The forecasts for 2026 point to increases in citizen receipts of 4% in tolls and 10.5% in charges to finance system adjustments. For now, the clock is ticking: the public hearing process for agents to send their allegations to the CNMC proposal will end on March 20, 2026.
Connect the future. Spain finds itself at an ironic and dangerous crossroads. The country has everything to be the great green battery of Europe, but the lack of cables and excess bureaucracy threaten to extinguish that potential. As a summary from the business sector“the plans are very nice, but they have to be built.”
The arrival of flexible access permits demonstrates that the electrical grid is no longer just infrastructure; It is an intelligent institution that must learn to manage itself better. Giving flexibility to the system has ceased to be a technical option and has become the only realistic escape route that will prevent reindustrialization, data centers and housing from dying of success due to the lack of a simple plug.
