Generators & power management are the systems that produce electrical supply and control load behaviour under variable onboard demand. At Berthon Spain, generators and power management form a core part of our marine electrical systems work, supporting stable operation, predictable performance, and long-duration reliability. Generators and power management support propulsion support systems, hotel loads, navigation infrastructure, and onboard services. These systems operate continuously under changing demand, which requires accurate sizing, controlled load behaviour, and stable integration with the yacht’s electrical distribution.
Generator selection and system design define how electrical power performs under real operating conditions. Generator selection matches capacity to continuous load, peak demand, and usage patterns rather than nominal ratings. Generator sizing uses measured and calculated electrical demand across normal operation, peak usage, and contingency scenarios. Generator selection accounts for simultaneous loads such as air conditioning, galley equipment, stabilisation systems, and navigation infrastructure operating together. System design also considers redundancy requirements, duty cycles, physical integration, and access for maintenance. These factors determine long-term reliability and serviceability.
Generator integration and commissioning connect new or upgraded generators into the yacht’s electrical system. Integration aligns generators with switchgear, distribution, and power management equipment so that load transitions remain stable. Commissioning verifies generator performance under load by confirming voltage stability, frequency control, and response to step load changes. Testing also confirms protective behaviour and safe operation before the generator enters service. This process ensures generators operate predictably during both steady operation and rapid demand changes.
Power management and load control regulate how electrical demand behaves across the vessel. Power management systems monitor load, prioritise circuits, and control generator response as demand fluctuates. Load control separates critical and non-critical systems. Prioritisation prevents overload, stabilises supply, and maintains continuity when demand increases suddenly. Controlled load behaviour improves generator lifespan and reduces unplanned shutdowns. Power management focuses on electrical stability and demand control rather than automation logic or system programming.
Reliability and protection systems prevent electrical faults from escalating into operational failures. Protection devices isolate faults quickly and limit damage to generators and connected equipment. Fault prevention relies on correct system configuration, predictable load behaviour, and coordinated protection that isolates faults before escalation. These measures reduce downtime and support continuous operation during extended generator use. Reliability planning also supports long-duration operation where generators run for sustained periods under varying demand.
Generators and power management in yacht refits modernise electrical capacity without disrupting existing systems. Refits address increased demand, ageing equipment, or changes in onboard usage. Refits often follow increases in electrical demand, extended generator run times, or repeated load instability. Generator upgrades replace or supplement existing units, while power management upgrades improve load behaviour and stability. Integration preserves compatibility with existing electrical distribution and protection systems. Refit planning reduces downtime and supports phased installation when vessels remain operational.
Generators and power management operate as part of the wider electrical infrastructure. These systems depend on correctly designed electrical distribution, protection, and energy storage.
