One complete system.
Four parts.
The water that has passed the plant still carries energy. The system captures it downstream, in the existing canal.
Floating turbines are mounted downstream in the canal and capture kinetic energy that would otherwise be lost. This typically adds 1–3 GWh per plant per year.
We measure flow, depth and geometry in the canal with drone scanning of current speeds and water levels. From the measurements we calculate the plant's production potential. The result is a clear basis for decisions ahead of installation.
The turbines are installed floating in the outflow canal with the rotor below the surface, converting the water's kinetic energy into electricity. Each unit is equipped with sensors and telemetry. No rebuilding of the plant is required.
SeaPattern's modular anchoring system enables optimal turbine placement based on each plant's unique conditions. The system is installed in the existing canal without new dams or interventions in the watercourse and is designed to minimize impact on the bed sediments.
The electricity produced is converted into grid-ready power and integrated with the plant's existing grid connection, or stored in battery banks.
Four parts.
One delivery.
Drones scan current speed and water level. The plant's exact potential is calculated before any decision.
Floating turbines with sensors and telemetry capture the kinetic energy in water that has already passed the plant.
Mounted in the existing canal, with no new dams or interventions in the bed. Each turbine's position is tuned for maximum energy capture.
The electricity is converted into grid-ready power and connected to the plant's existing grid connection, or stored in battery banks.

Technical details
The choice of turbine is based on research focused on low environmental impact, and its environmental properties have been validated in scientific studies.
See our impact →Multiple field test campaigns conducted at Tekniska Verken's Svartåfors hydropower plant.
See the solution →The number of turbines is flexible and set by the target: annual output in GWh or capacity in kW.
