Beyond the blackout: a necessary boost for renewable energy

Spain recently experienced a major power outage that set off alarm bells nationwide. The government’s response, through its new “anti-blackout” royal decree-law, includes both reactive measures — more inspections and oversight — and proactive ones, with a strong commitment to renewable energy and energy storage.

This dual approach raises a key question for Wegsco and the sustainable sector:

How can we contribute through technology and innovation to strengthen Spain’s energy resilience and accelerate the ecological transition?

1. Political and technical context of the blackout

The blackout exposed the system’s fragility. According to the Ministry for the Ecological Transition, mechanisms were in place to prevent a collapse, but they were not correctly applied. There was a lack of foresight, coordination among stakeholders, and real-time technical response.

Now, Spain’s energy regulator (CNMC) will more strictly supervise all operators and will issue reports every six months to ensure they fulfill their voltage control obligations.

The decree includes measures such as:

  • Audits of operators and power companies to identify weak points.
  • Cutting red tape to speed up renewable and battery installations.

2. Renewables and storage: the heart of the decree

A key pillar of the new decree is to promote energy storage, prioritizing the installation of batteries in existing renewable plants. This will help to:

  • Reduce losses from grid saturation (“curtailments”).
  • Extend the use of solar or wind energy to hours without sun or wind.
  • Minimize environmental impact by acting on already utilized sites.

As Minister Sara Aagesen explained, the aim is to spread the benefits of renewables over time and improve system efficiency.

Less bureaucracy, more electrification

The decree also includes measures to accelerate clean energy deployment:

  • More flexible deadlines and simpler permits for new wind and solar projects.
  • Faster installation of EV charging stations, which will no longer require prior authorization.
  • Boost to self-consumption, expanding the connection radius from 2 to 5 km for installations up to 5 MW.
  • Tax incentives for technologies like aerothermal systems, with reductions in property and construction taxes.

Opportunity or mere reaction?

At Wegsco, we believe this reform is a step in the right direction, but it must be more than a one-time reaction. We need to consolidate an energy model that is:

  • Decentralized, with distributed generation and stronger local involvement.
  • Digitalized, to anticipate and correct failures with real-time data.
  • Regenerative, not only cutting emissions but actively improving the environments where it is implemented.

The energy transition cannot rely on blackouts to move forward. It’s critical to anticipate needs and design a system that is more robust, cleaner, and fairer for everyone.
