The energy transition progresses strongly, but does so on a fragile base. According to the International Energy Agency, In your latest reportthis year 3.3 billion dollars in energy will be invested and only 12% will go to the networks. The imbalance is evident. And also worrying.
A worrying imbalance. According to the IEAfor every dollar destined to produce electricity, just 40 cents are invested in transport networks. There are even more, the transformers can take up to four years to be available. To that is added a worrying increase. Since 2018, the prices of cables and transformers have doubled, making the expansion of infrastructure that support the system even more difficult and expensive.
Is there a risk of blackout? The IEA has made it clear: “Entrepreneurship safety requires a rapid increase in networks.” A warning that resonates strongly on the Iberian Peninsula, which the report mentions as a case study after The April 2025 blackout.
As for the blackout, and even without definitive official causes, everything indicates that it was not caused solely by the low inertia of the system, as initially suggested, but by a chain of chained technical failures. However, what this incident illustrates a structural problem: Investment in infrastructure and support technologies, such as MicroRedes either storage. Without a reinforced and prepared network to manage an increasingly complex electrical system, you can suffer interruptions.
A bottleneck. There is even more, because a human capital challenge is added to investment problems. IEA has estimated that by 2030 there will be a deficit of 1.5 million workers qualified in electrical networks. This shortage affects key tasks such as the installation of transformers, digital systems or advanced control. In addition, planning and permits are slow processes. Networks require more than cables: they need intelligence, distributed control and resilience against failures.
Are there solutions on the horizon? IEA has proposed Two clear lines: on the one hand, long -term network plans (minimum 10 years) such as those already applied India, Brazil or South Africa; And on the other, bet on digitalizationwhich already represents 25% of the global investment in electrical networks.
The urgency of reinforcement. The final warning of the report does not leave interpretations: “Without action, the electrical networks will be the bottleneck of the energy transition” without a modern, robust and prepared network to manage variable clean energy, the green transition will not only be inefficient: it can become insecure. Renewable growth cannot be sustained on infrastructure of the twentieth century. So here a fairly clear question underlies: are we reinforcing our electrical networks with the same ambition with which we install renewables, or are we building on unstable terrain?
