Emergency diesel generators are started when the NPP unit is disconnected from the grid. Emergency diesel generators safeguard the power supply to vital consumers such as the reactor cooling system so that a controlled reactor shutdown can be guaranteed.

MTU Onsite Energy has been supplying emergency diesel generators (EDGs) for nuclear power plants for more than 50 years. With over 300 systems supplied worldwide, we have gained a wealth of experience and expertise – and a reputation for products that deliver outstanding reliability and performance.

It goes without saying that all EDG projects are organized and implemented in line with NPP-related quality standards such as IAEA 50-C-QA and KTA 1401. Our EDGs are safety-classified to meet the strictest regulations in the nuclear power industry, with qualifications in line with IEEE 387 and KTA 3702, for example. In addition, our NPP-specific digital engine controller, SafeDEC, is qualified to comply with IEC 60880 standards, for which it was developed.

    MTU Onsite Energy EDGs combine the shortest start-up time in the NPP sector – just ten seconds – with a load-acceptance capability of 50% for the first load step.

    Every customer and every project is different. That’s why MTU Onsite Energy has developed a major NPP-based engineering section with some 100 specialists capable of handling every aspect of project-specific NPP requirements.

    Whether you’re planning a new build or a modernization project, our combination of outstanding technology, over half a century of proven reliability and the expertise of our specialist NPP engineering staff mean that MTU Onsite Energy is a partner you can rely on.
