The article, titled “Storage so that darkness does not fall over light”, focuses on one of the major structural challenges of the energy transition: the need to deploy storage systems to ensure the security and stability of electricity supply.

The publication coincides with the first anniversary of the major blackout on 28 April 2025, an event in which “in just five seconds”, 15,000 MW of electricity were disconnected across the Iberian Peninsula due to an overvoltage issue. This incident highlighted the “vulnerability of the energy system” and the need to strengthen its resilience against potential disruptions.

In a context marked by geopolitical volatility and a growing demand for energy security, storage is becoming a key element to prevent risk situations and ensure supply continuity.

The strategic role of batteries

The feature, written by journalist Jordi Garriga Riu, gathers insights from several sector experts on the role of batteries and energy management in the new energy model.

Among the highlighted contributions are those from professionals and companies linked to the Clúster de l’Energia Eficient de Catalunya, who agree on the need to move towards a more flexible and resilient system.

In this regard, Jaume Cayetano, CEO of MORILLO ENERGY RENT, emphasises the importance of having contingency plans in place for unexpected situations: “Power outages occur regularly due to storms, wind events, etc., which is why a contingency plan is necessary to be resilient.”

Miguel Ángel Artiel, Technical Director of the same company, highlights that “there are still issues with construction permits, companies are told there is no available space, and the environmental impact assessment process is particularly slow.”

Meanwhile, Gorka Martí, Operations and Services Director at sonnen Spain, points to Catalonia’s strong potential for the development of storage systems, both due to its characteristics and its level of energy consumption. According to Martí, the combination of self-consumption and batteries can enable “levels of energy independence between 70% and 80%”.

In the same line, Daniel Pérez Rodríguez, Director of the public company L’Energètica, notes that batteries were already a necessity before the blackout to ensure the economic viability of the energy transition. He also stresses that the hybridisation of renewable energy and storage systems will be a key element in the development of new installations, especially in the photovoltaic sector.

A shared sector vision

The article also includes contributions from other energy experts, such as Lluís Pinós Jorba, President of the Energy Commission of Enginyers Industrials de Catalunya (EIC); Enric Pardo, spokesperson for Renovem-nos; Pau Sales, energy transition technician at the City Council of Terrassa and collaborator of AMEP; as well as sources from Endesa’s distribution network.
