The country's capital, Helsinki, uses water from Vantaanjoki as its backup water supply if the Päijänne Water Tunnel needs to be repaired.^[1]

The Helsinki-based energy company Helsingin Energia has a working power station museum located at the mouth of Vantaanjoki. The Vanhakaupunki Hydropower Plant produces an average of 500 MWh annually.^[2]
