Feed barges with limited shore power
Local support during short peaks and rapid load changes, without having to size the shore power for maximum simultaneous load.
Shore power for aquaculture and feed barges in weak grids
Faster electrification with less grid reinforcement
eqGrid helps fish farms and feed barges make better use of existing shore power and grid capacity, so electrification can be carried out faster and at lower connection costs.
Aquaculture and feed barges
Stylised feed barge.
What eqGrid brings to aquaculture
eqGrid is not a replacement for the grid. It increases the use of the existing connection and supports the load profiles that often make shore power challenging at sea sites.
Voltage support in weak grids
Stabilises voltage locally when feed blowers, pumps, compressors and other equipment cause rapid changes in power draw.
Transient support during motor starts
Battery and power electronics can help during brief power peaks and reduce practical limitations in weak grids.
Hybrid operation between grid and generator
Can operate with shore power, battery and generator to reduce diesel use and increase robustness in local supply.
Workboats and charging
Electric and hybrid workboats draw high power over short periods. A local power buffer can reduce the load on the grid.
Lower need for grid reinforcement
By reducing peak load and improving voltage quality, eqGrid can contribute to faster electrification and lower connection costs.
Grid capacity and power demand in aquaculture
Several analyses indicate that many aquaculture regions have limited grid capacity, long connection processes and high simultaneity between smaller loads.
Shore power for aquaculture and sea sites
- Increased electrification of aquaculture raises the load on the grid
- Many simultaneous loads can be demanding for the distribution grid
- Grid reinforcement can mean high connection charges and long lead times
- Local flexibility can give better use of the existing grid
