Emergency Power Supply

WE HELP GRID OPERATORS TO MAKE GERMANY'S TRANSMISSION GRIDS SAFER AND MORE RELIABLE


Based on the EU Regulation 2017/2196 of 24 November 2017 establishing a network code on electricity emergency and restoration, various transmission system operators have started to equip their substations with emergency generating units to warrant a self-sufficient uninterrupted supply time of at least 72 hours in the event of outage of the MV distribution system.

 

In the course of implementing such measures, we have worked together with various transmission system operators on the specific development of emergency generating units based on diesel generators that take particular account of specific requirements in terms of integrating remote signal exchange, maintenance concepts, regular trial runs etc. Since 2017 we have already produced about 30 units in various output categories and commissioned these on site with the respective operator. More units in high double-digit quantities are currently undergoing production or are in the preliminary planning stage for the next few years. Furthermore, we enter into detailed discussions with the respective operators about individual maintenance concepts and conclude service agreements with warranted on-call standby times etc.

H2 Energy Technologies

A climate-friendly alternative for the future


Over the last 56 years, Frerk has become established as an expert, reliable system integrator for turnkey stationary solutions for generating heat and power. With its new division FRERK H2 Energy Technologies, FRERK is now addressing the challenges of future technologies. FRERK H2 Energy Technologies takes on a leading role in the development and system integration of emergency generating units with hydrogen fuel cells, thus helping to supply our planet with clean energy.

As a first step, FRERK H2 Energy Technologies is starting cooperation with Proton Motor Fuel Cell GmbH in the field of stationary emergency power supply for critical infrastructures such as data centres, hospitals and public facilities. These systems will naturally also be available as turnkey container solutions, particularly for international demand.

Frerk Power Plant

3.5MW 10KV EMERGENCY DIESEL GENERATOR SET FOR NORTHERN PACIFIC OIL AND GAS PROJECT


Successful Witness Testing during the Corona Pandemic thanks to Remote Accessibility:

Frerk has recently successfully completed and passed a very comprehensive Factory Acceptance Test (FAT) of a 3.5MW@10kV-Emergency Diesel Generator Package for an Oil & Gas project in Northern Pacific Ocean.

The particularity of this FAT was that the complete test was performed with remote access for the EPC Contractor and the End-Client since the project engineers could not travel.

The complete tests was utilising Frerk’s web cam, web meeting and connected chat capabilities to witness every aspect of the installation and thus be closely involved with the inspection and acceptance process of the installation.

The complete tests lasted a complete week and among others the following tests were performed:

  • 8 hours 100% full load test
  • Dynamic response test of the generator set; load application and rejection
  • Functional test of the Generator Set Controls including synchronisation and signal interface checks
  • String test of Fire & Gas detection and CO2-extinguishing system
  • String test of all auxiliary systems (i.e. ventilation, fuel supply, redundant pneumatic start and black start simulation)
  • PMI-test of all stainless steel piping & instruments
  • Radiographic examination of weld seams
