Shore power, peak loads & port efficiency: The new energy challenge for commercial fleets
The maritime world is undergoing constant change. With the green movement gaining momentum and regulations becoming ever stricter, commercial fleets now need not only be highly effective transportation systems but also environmentally friendly.
One of the main drivers of that change is the use of shore power. Thanks to the possibility to supply the vessel with electricity from the local grid, the use of shore power significantly decreases fuel consumption, CO2 emissions, and noise levels in the ports.
However, any technological revolution inevitably brings about certain problems. Ports need to find the way to address these new challenges and ensure efficient management of energy consumption.
Shore power: A greener path forward
Conventionally, ships used auxiliary engines to produce power at port. While this method works well, it wastes fuel and causes emissions, even though ships aren’t moving.
There’s a better way for ships to receive power from a port.
With shore power, ships plug into the port’s power supply system, enabling them to turn off their own generators and receive power from the grid. This leads to fuel savings, emission reductions, reduced noise levels, and cleaner air for nearby residents.
For many ports, shore power technology is now the reality rather than the future.
The challenge behind the plug
As much as the ecological advantages of using shore power have been proven, energy demands from the process are very high.
Large commercial vessels need a great deal of electricity while docked at a port. At one moment, many vessels might plug into shore power, causing a sudden spike in the energy demand.
Such spikes, which are referred to as peak loads, can cause significant stress for ports’ electricity infrastructures.
Without proper management mechanisms, ports can be unable to meet the needs for energy, experience inefficiencies, incur extra expenses, or face even worse challenges such as affecting ship turnaround times. That said, it is important that energy management should be better for higher numbers of ships plugging into shore power.
Why peak load management is important
Peak load management is not simply about engineering, but also about business.
Access to adequate and reliable power determines efficiency in operations. Without enough capacity, delays and other kinds of complications can arise.
This is why ports are now incorporating energy management systems capable of monitoring energy needs, balancing the electrical load, and ensuring that power goes where it is required.
For the fleets, this ensures consistency and reduces chances of disruptions in their port calls.
Port efficiency involves energy management too
Traditionally, discussions regarding port efficiency focused on aspects like cranes, containers, and cargo handling. However, nowadays, energy consumption is gaining ground too.
The most efficient ports are the ones that not only work well but are also smart when it comes to energy management.
That includes investing in such technologies as:
- Shore power infrastructure
- Effective electrical networks
- Energy storage systems
- Load balancing mechanisms
- Renewable energy integration
These solutions allow ports to ensure that increasing amounts of power do not disrupt their high-performance operations.
