An expansion project, expected to comprise around 40 turbines with a capacity of 15 MW each, is currently in development with completion targeted for 2027.

The initial plan was to first build a demonstration project with two 15 MW wind turbines to pilot large-scale offshore wind turbine and foundation concepts, and construction methods for deep waters (15-45 metres), but Tahkoluoto Offshore Oy dropped the demo project last year and said it would move forward with the full expansion project.
