STS PORT CRANE
PEAK SHAVING

Ultracapacitor SkelGrid - reliable grid supply without frequency fluctuations

Benefits of our solution

  • Reduced peak load demand on grid connection point
  • Mitigated voltage and frequency fluctuations 
  • Avoided costs related to expanding grid connection point
  • Avoided costs related to power line capacity
  • Uninterrupted operation of cranes
  • No need for oversized battery solutions

Challenge

Reliable grid supply without frequency fluctuations

  • Key Challenges
  • Just-in-time container handling in ports
  • Reliable grid supply as requirement for operation
  • Downtime is not accepted
  • Increasing power line capacity often too costly, especially at the "end of line” 
  • known consequences
  • Continuous parallel operation of STS (Ship-to-shore) cranes triggers high peak load on grid  and causes significant voltage and frequency fluctuations
  • Increased risk of grid blackouts
  • Heavy costs for the port crane area downtime
