Port of Pori

The Port of Pori is a place between places – where land meets sea, and compass directions converge, serving as a hub for exports and imports. The port’s infrastructure includes areas such as Mäntyluoto and Tahkoluoto.

We built a serverless technology-based solution for the Port of Pori, where energy consumption for lighting in the port area is minimized by reducing lighting in areas where there are no ships or other activities. The project originated from a pilot project by the Prizztech Oy economic and development company, which commissioned a feasibility study for implementing data-driven lighting control. The purpose of the study was to find ways to intelligently control lighting in different situations within the port area.

Dyme conducted an extensive feasibility study in spring 2023. The study identified key data sources relevant to the operations of the Port of Pori, based on which lighting could be controlled in various situations. Additionally, algorithms and technical architecture were planned during the feasibility study for controlling lighting based on data from different sources. As part of the study, a calculation was made showing a significant potential reduction in energy consumption related to port area lighting.

Feasibility study, data-driven lighting control

Feasibility study, energy-saving potential for lighting

Based on the observations and plans made during the feasibility study, Dyme implemented a data-driven solution for the Port of Pori in summer 2023, which controls and optimizes lighting over a wide area. The pilot project for the system was conducted in the Port of Pori area, utilizing internal and third-party systems and services related to port operations.

Final report, data-driven lighting control for the Port of Pori

Technically, the system was implemented on the AWS cloud platform using a serverless approach. Since the system consists of multiple data sources, from which control commands are generated, it was natural to implement the system on an event-driven architecture (EDA) basis. At the core of the lighting control center is the EventBridge event bus, which serves as the hub for all event traffic. Control signals and commands were stored in an AWS DynamoDB database. The infrastructure description was created using Terraform code.

After the pilot project, the system has been gradually expanded to operate in different areas of the port, and new data sources controlling lighting have been integrated into the control system.
