JUB

About the project

  • The international company JUB d.o.o. wanted a cheaper and more reliable alternative to their heat and power supply and to improve their self-sufficiency. Consequently, Interenergo evaluated various options in terms of technical and economic suitability and company needs.
  • Interenergo experts chose cogeneration as the best solution and appropriately assessed the need for the combined production of heat and power (CHP). The company used to heat its premises using gas boilers and received all its electricity from the grid.
  • As part of the renovation, Interenergo installed an additional CHP plant with 360 kW of power and 390 kW of heat output. The JUB industrial building will now have a self-sufficiency rate of 68 and 72 per cent in power and heat, respectively.
  • From now on, gas boilers will only cover peak loads and serve as a backup in the event of CHP malfunction, while the implementation of a central control system will allow remote control and operation.
  • Through improved energy efficiency and lower primary energy consumption, the company will achieve financial savings.
