Cruïlla, the first major festival powered entirely by renewable energy

One of the clearest examples of this shift is the Cruïlla Festival, an unmissable highlight of the summer calendar at Barcelona's Parc del Fòrum. In recent years, the festival has achieved a milestone that once seemed imposible for a mass event of its scale: running entirely on renewable energy.

The festival bypassed the heavy-duty diesel generators that have been the industry norm for decades, connecting directly to a sustainable electricity grid instead. The environmental savings speak for themselves:  nearly 36,000 kilograms of CO₂ emissions prevented and over 13,600 litres of fuel saved each year.

Beyond the metrics, this milestone carries considerable symbolic weight. For the first time, a major festival has proven that it is possible to deliver world-class production values—high-spec stages, lighting, and sound—without relying on fossil fuels. This model is actively reducing the environmental impact, reshaping consumer expectations, and pushing audiences to demand that events genuinely align with the green values they promote.

Cruïlla's commitment extends far beyond power. The festival champions sustainable transport links, zero-waste initiatives, and locally sourced catering. This shift towards sustainability is no coincidence: behind the festival's renewable supply is Endesa. As the festival's official energy partner, Endesa has turned Cruïlla into a real-world showcase for how clean electrification can sustainably power the future of the live music industry.

Tarragona blends tradition with drones

This transformation is not limited to commercial music festivals like Cruïlla. In Tarragona, the International Fireworks Competition—an event steeped in decades of local heritage—is embracing new forms of innovation. Alongside the traditional pyrotechnic displays, the competition now incorporates synchronised drone shows that offer a quieter, visually stunning alternative.

This shift is as much a social innovation as a technological one. This alternative allows individuals with sensory sensitivities, PTSD, or autism to enjoy the festivities without the distress caused by loud traditional fireworks.

The case of Tarragona provides a clear takeaway: energy innovation isn't solely about reducing emissions, but also about increasing accessibility and inclusion. Culture is adapting to increasingly diverse audiences, thereby strengthening its social impact. Added to this is a less conspicuous but equally relevant effort: cleaning the coastline after every show, which incorporates sustainability into environmental management and the organisation's own responsibility. These initiatives are also supported by Endesa, which sponsors the competition as part of its commitment to combining energy innovation and cultural heritage.

The Pyrenees: where energy is part of the cultural narrative

In contrast to these urban festivals, the Catalan Pyrenees provide another example of how energy can uniquely form part of culture. The Dansàneu Festival, dedicated to the region's cultures, has incorporated hydroelectric heritage into its venues. Former power stations are thus transformed into cultural spaces hosting concerts, exhibitions, and other activities.

The result is an experience that bridges past and present: energy ceases to be an invisible element and becomes a central part of the cultural narrative. Through historical archives, guided tours, or performances set against backdrops of vintage machinery, audiences can explore the role that electrification played in the region's development. This approach provides added value: it's not just about consuming culture, but about understanding the context that made it possible. Endesa , which historically tied to the construction of these Pyrenean hydroelectric stations, collaborates with the festival to breathe new life into these historic industrial assets.

Even local festivals are adapting

This evolution is also reaching historic neighbourhood celebrations, such as the popular Gràcia festival in Barcelona. For a week, the streets of Gràcia brings together concerts, popular culture, and community activities, increasingly standing out for its ability to adapt to new public sensibilities. Its programme incorporates initiatives linked to sustainability, as well as more accessible proposals, such as adapted concerts or activities designed for different groups – a drive that Endesa also participates in as one of the companies supporting these initiatives.

This transition is designed to be evolutionary rather than revolutionary. Traditions remain intact—the carrers guarnits (decorated streets), neighbourhood concerts, traditional cultural activities—but they now coexist with modern practices that reflect modern-day concerns. Energy thus becomes a common thread connecting innovation, responsibility, and experience.

A new blueprint for cultural events

All these examples – Cruïlla, the Tarragona fireworks, Dansàneu, and the Gràcia festival – point to the same phenomenon: the emergence of a new festival model. It is no longer enough for an event simply to entertain. Modern audiences expect cultural gatherings to be ecologically responsible, socially inclusive, and respectful of their local environments. Energy is no longer just an invisible utility; it becomes a key factor in this transformation, not only for its technical impact but for its ability to convey values.

The future of festivals in Catalonia seems to be moving towards this convergence of culture and sustainability. Concerts powered by clean energy, more inclusive popular festivals, and events that highlight energy heritage are just the beginning. The cultural experience of the future will not be measured solely by what happens on stage, but also by how it is made possible.
