On April 28, 2025, the Petronor refinery in Muskiz, Bizkaia, faced a significant operational disruption due to a power outage, leading to the activation of emergency protocols and the shutdown of all refinery units. The incident has raised concerns among local residents, particularly due to the visible black smoke emitted from the three safety torches at the facility.
According to reports, the electricity supply was interrupted around 12:30 PM for reasons that remain unclear. This led to the automatic activation of all safety measures in place at the refinery. As a result, black smoke began to billow from the torches, which are essential safety devices designed to release pressure during specific situations.
Petronor reassured the public that the smoke was not a cause for alarm but rather an indication that safety systems were functioning correctly. The company stated, "The torches are monitored continuously, measuring flow rates, temperature, and flame appearance, and all components are inspected regularly." This monitoring is critical for ensuring safety during operational anomalies.
Mayor Eduardo Briones of Muskiz confirmed that the smoke was a direct consequence of the refinery's safety protocol, which dictates that all production must be burned off during power outages to prevent any hazardous emissions. "This situation is unusual, but it is part of our safety measures," he explained.
Despite the return of electricity to the facility later in the day, the refinery remains halted, and the restart process has yet to begin. Petronor emphasized that all emergency systems were functioning correctly, and the plant had been secured under safe conditions.
The company elaborated that the torches play a crucial role in burning off gases that could otherwise be released into the atmosphere. Although the smoke can appear dramatic, it is a necessary safety measure. "Occasionally, the torches can produce significant smoke, but this is proof that they are working as intended," a spokesperson for Petronor stated.
Local residents expressed their concerns over the smoke, with some reporting visibility issues and a lingering odor in the area. However, Petronor has assured that the situation posed no risk to public health or significant alterations to air quality.
In light of the incident, Petronor has communicated with various local authorities, including the Vice-Ministry of Environment of the Basque Government, to keep them informed of the situation and the safety measures being taken. This proactive communication aims to alleviate public concerns and maintain transparency regarding the refinery's operations.
The refinery, a key player in the region's industrial landscape, has protocols in place for various emergency scenarios. The current incident highlights the importance of these measures in ensuring safety for both the facility and the surrounding community.
As the situation develops, Petronor continues to monitor the facility closely, preparing for a safe restart once conditions allow. The company remains committed to maintaining the highest safety standards while addressing the concerns of the local population.
In summary, the power outage at the Petronor refinery has led to a series of safety protocols being activated, resulting in the emission of black smoke from the facility's torches. While this has caused some alarm among local residents, the company has assured that all safety measures are functioning correctly and that there is no immediate risk to public health.
