Intelligent field lighting controls save energy and reduce the carbon footprint of the harbour

The amount of diffused light carrying to the nearby areas in the Vuosaari Harbour has been restricted significantly.

The automated control of the Vuosaari Harbour field lighting was renewed in 2019. This resulted in a more flexible and secure lighting system that is able to serve customers better. In addition to this, energy savings are expected.

The intelligent lighting control project started in Vuosaari Harbour last spring. The new control system was introduced in September.

– Even though Vuosaari Harbour has only been around for 11 years, its electronics have started to reach the end of their lifecycle. We were experiencing some usage issues with our lighting poles, Electricity Manager Tarmo Purho explains.

Flexibility through intelligence 

Schneider customised the software for the system according to the needs and wishes of the harbour. Harbours own personnel themselves installed the terminal devices and dismantled the old system.

Now, all 86 lighting poles at Vuosaari Harbour have an intelligent terminal device that does not require a server for support at all times. 

– Disturbances in the IT network, for example, will not affect our lighting, Purho says. 

The major issue with the old system was that the order of priority of the different lighting sections could not be changed flexibly. The new system, on the other hand, is light and flexible and allows for easy programming of any future changes. The system allows the lighting to be timed so that the work lighting in certain areas can be scheduled to switch off according to the working times of operators at work in the area, for example. The order of priority can be altered flexibly in various areas.

Savings in energy consumption and costs and a smaller carbon footprint

– Instead of manual controls, we were now able to employ a more suitable automated system to run in the background. We are able to cut back on unnecessary lighting, the electricity manager says with a smile.

Better and more secure lighting is expected to generate savings in energy consumption, CO2 emissions and euros alike. 
– It is still too early to start calculating savings, as we have been using the system for only a few months. When the user interfaces are implemented for operators, consumption will likely continue to decrease. We will be able to calculate the impact on energy consumption and the resulting CO2 emissions in early 2020, Purho estimates.

– Either way, switching to LED lighting and employing automation plays a significant role in our journey to becoming carbon neutral by 2035.

The switch to LED lights will be gradual

As more luminous LEDs have been developed, and especially now that white LED, which is more pleasing to the human eye, has been invented, Vuosaari Harbour will gradually swift to using only energy-efficient LED lights. Lamps will be changed cost-effectively as they come to the end of their lifecycle. It is estimated that LEDs will be used for the entire field lighting system of Vuosaari Harbour by 2030.
