QualityWatch for fuels from emergency power systems

Aged fuels in the tank jeopardize the usability of emergency power generators. QualityWatch of emergency power systems is a comprehensive service offered by TEC4FUELS for monitoring the quality of fuel stocks. It consists of a basic service and as per requirements, additional services can be selected.

Many companies, health or social institutions, as well as internal security, civil defence and disaster control organisations operate emergency power supply systems in order to be able to ensure the necessary supply of electrical energy independently of the mains during an emergency. Electricity is indispensable in particular for the use of modern information and communication technology. Regular maintenance and test runs of motors and generators should guarantee the operational safety of the emergency power supply. Experience shows, however, that the quality monitoring of the fuel supply in the storage tanks has so far received little attention from the operators.

A current study shows: The fuel required for the systems, on the other hand, is hardly in the focus of the operators. This is doubly critical: standby fuels are often stored for years – but due to their chemical properties, their storage capacity is limited. Fuels in emergency power systems are never completely replaced, as their tanks should never be empty at any time. When refuelling, new fuel thus mixes with aged stocks. In the study, 60 percent of the diesel fuels used with a biodiesel content were unusable – or about to be. This critical fuel quality means that the reliable operational readiness of emergency power systems is not assured today.
