What makes Barcelona's Cruïlla Festival Spain's only 100% renewable festival?
Thousands of attendees, stages, lighting, and music for hours. Behind a great festival lies a massive demand for energy. But is it possible to power it solely with renewable energy? In Spain, only one has achieved this: the Cruïlla Barcelona Festival. We explore what made this milestone possible and the technology behind this sustainable model.
What does it mean for the Cruïlla Festival to be 100% electrified?
The Cruïlla Festival, held at the Parc del Fòrum in Barcelona, is the first major music festival in Spain to run entirely on electricity from renewable sources, without resorting to fossil fuel generators.
This model, championed by Endesa since 2023, has been reinforced with a new collaboration agreement for a further three years. The renewal consolidates a pioneering initiative in the electrification of cultural events.
The key lies in combining electricity from renewable sources, grid infrastructure, and technical planning to ensure a continuous, secure supply tailored to the high energy demands of an event of this scale.
Thanks to this complete electrification, the festival eliminates the use of diesel generators, reducing the environmental impact associated with generating electricity for the event.
The environmental impact of the Cruïlla Festival: energy consumed and CO₂ avoided
In its latest edition, the Cruïlla Festival consumed 61,640 kWh of electricity, all from renewable sources. Thanks to this model, the emission of 17,259 kg of CO₂ was avoided. This reduction is achieved by replacing the diesel generators typically used at this type of event with a renewable electricity supply from the grid.
These figures make the Endesa–Cruïlla model a tangible example of how electrifying an event can help reduce emissions in a concrete and measurable way, reinforcing the festival's position as a sustainability benchmark within the large-scale music events sector in Spain.
How the electricity supply is guaranteed at a 100% renewable festival
To ensure the electricity supply during the four days of the festival, Endesa temporarily adapts the local distribution grid and activates a specific plan integrating technical, operational, and monitoring measures.
These include reconfiguring the electricity grid by dedicating an exclusive medium-voltage line to the Parc del Fòrum venue and diverting normal consumption to alternative lines, alongside an additional connection that provides redundancy to the system.
The plan also includes a preventive review of the facilities, with a full inspection of the transformer substations and switching systems, as well as thermography to detect potential critical points prior to the event.
During the festival days, the grid operates with a specific configuration to meet the venue's demand without compromising the normal supply to users in the area. Once the event is over, it reverts to its standard configuration.
Beyond renewable energy: other sustainable measures at Cruïlla
Alongside electrification, the festival also features other initiatives aimed at reducing the event's environmental impact and enhancing the attendee experience.
These include a reusable cup system, which helps reduce the use of single-use packaging through sorted collection, cleaning, and continuous reuse of cups throughout the event. This drives a more efficient consumption cycle and reinforces the event's commitment to lowering its environmental impact.
Initiatives are also promoted to improve accessibility and the overall experience for all attendees, such as noise-reducing headphones designed to provide a more comfortable experience for those who need a gentler soundscape within the venue.
The Cruïlla Festival model proves that the complete electrification of a major music event is a reality in Spain.
With the renewal of the agreement for a further three years, this pioneering model can be consolidated to inspire other festivals and major events to follow the same path.
FAQs
The Cruïlla Festival runs on electricity from renewable sources thanks to its connection to the Parc del Fòrum electricity grid, completely avoiding the use of diesel generators during the event.
Endesa adapts the local distribution grid with dedicated lines for the venue, redundancy systems, real-time monitoring, and technical teams that supervise consumption during the festival days.
Using 100% renewable electricity reduces CO₂ emissions. In its latest edition, the festival avoided over 17,000 kg of CO₂ thanks to the consumption of clean energy.
In addition to renewable energy, the festival incorporates reusable cups to reduce waste, and accessibility measures such as noise-reducing headphones to improve the attendee experience.
