The Port of Trelleborg’s investment in battery energy storage is entering its next phase. The new 4 MWh battery energy storage system (BESS) is now in place at the port, with testing scheduled to begin within a month. Once testing has been successfully completed, the system will be ready to become operational.
The battery storage system is an important part of the Port of Trelleborg’s ongoing energy transition and will primarily be used to balance electricity demand and reduce peak loads. This will be particularly important when several vessels are berthed and connected to onshore power supply simultaneously.
– Having the battery storage system in place marks another important step in the development of our energy system. It will enable us to make even better use of the renewable electricity we generate ourselves, reduce peak loads and support the continued electrification of the port. We are now looking forward to the testing phase and, once completed, putting the system into operation, says Håkan Nilsson, Technical Development Manager at the Port of Trelleborg.
The Port of Trelleborg already generates its own renewable electricity from two wind turbines, producing approximately 17 million kWh per year. This means that, on an annual basis, the port generates enough electricity to cover its own consumption.
The battery storage system will allow more of the electricity generated by the port to be stored when supply is high and used when demand peaks. This provides greater flexibility in the port’s energy use and supports the continued expansion of onshore power supply.
From 2030, EU regulations will also require larger vessels to use onshore power supply while berthed in port. As a result, the electricity demand at the berths in the Port of Trelleborg is expected to increase gradually.
