Backup power in critical healthcare environments: we designed a tailored emergency solution for a proton therapy centre

Genesal Energy designed and manufactured a soundproofed generator set specifically adapted for a proton therapy centre located in Santiago de Compostela (Spain).

This emergency power solution delivers 550 kVA to ensure the uninterrupted operation of high-precision medical equipment in the event of a grid failure.

These types of centres, dedicated to oncology treatments using protons, require a continuous power supply, as any interruption can not only compromise the effectiveness of the treatment but also put patient safety at risk. In addition, international regulations on advanced radiotherapy impose the mandatory requirement of having backup energy systems in place.

Safety, precision, and autonomy

Genesal Energy’s engineering department developed a GEN550YI generator set housed in a 4,500mm soundproofed enclosure, providing quiet operation and reliable performance. The generator starts up automatically in the event of a power outage, supplying the necessary energy to keep facilities and medical equipment running.

A dedicated exhaust system was also designed to minimise noise emissions, in compliance with current noise regulations.

Alongside reliability, the project required a solution with high operational autonomy. Two fuel tanks were included: an 800-litre base frame tank and an external double-walled tank with a 2,000-litre capacity. Both are connected through an automatic transfer system equipped with level sensors, a transfer pump, a cut-off solenoid valve, and a fuel filter, thus ensuring a continuous and safe supply.

A robust and silent design

The solution also incorporates a redundant start-up system with batteries in parallel to ensure the generator remains operational at all times. A dedicated exhaust system was also designed to minimise noise emissions, in compliance with current noise regulations.

The unit was manufactured using state-of-the-art technology, integrating a monoblock engine–alternator system with flexible coupling, which enhances overall reliability and reduces vibrations. Thanks to this bespoke design, the proton therapy centre in Santiago now benefits from a reliable, quiet, and long-lasting backup system that protects sensitive and costly equipment, guarantees the continuity of advanced medical treatments, and complies with the highest technical and regulatory standards in the healthcare sector.
