Case study overview

The Application

For safety reasons an uninterrupted power supply is needed during construction phase and longer maintenance periods for obstacle lights and pumps.
Power demand obstacle lights: Between 50 and 100 W
Power demand pumps: Approx. 25 W

The Challenge

During construction and maintenance work, no grid access is available but operation safety for obstacle lights and pumps still has to be guaranteed. Autonomy of up to three months is required, resulting in high service and operating cost for batteries and generators and high maintenance effort.

The Solution

Provide reliable off-grid power with a maintenance free and environmentally friendly EFOY Pro fuel cell, which will power your application for several weeks or even months without ever requiring user intervention.

The Benefits

  • Autonomous and Reliable off-grid Power Supply for Weeks – The EFOY Pro will produce electricity in any weather, climate or season, from the desert to the Arctic Circle. Helicopter flights to the wind power plants are avoided, saving an abundance of cost (around 30.000 € per flight).
  • Maintenance free power for long term use – EFOY Pro is maintenance free, the consumption of fuel can be calculated very accurately beforehand, allowing precise planning and avoiding unnecessary trips to exchange batteries every two days – reducing operating cost.
  • Easy and quick installation – The EFOY Pro is lightweight, compact and can easily be integrated into the tower or nacelle.
