Hybrid emergency power system hNEA

With the innovative new development of the hNEA, Jost AG Energietechnik is making a significant contribution to the reduction of CO2 emissions and thus to the responsible use of our resources.

A new approach to emergency power systems.

Backup power systems are indispensable for maintenance work on the power grid or for supplying power to construction sites, hospitals, data centers and more. Conventional systems often run at partial load, but the diesel engines are still constantly in operation, causing continuous noise, consuming diesel and emitting CO2.

In collaboration with BKW Energie AG and other partners, Jost AG has developed a completely new type of hybrid emergency power system.

The advantages:

  • 80% diesel savings
  • 80% CO2 reduction
  • Massive reduction in noise pollution
  • Electricity feed-in from photovoltaics possible during operation
  • Significant savings in operating and maintenance costs
  • High economic efficiency
