1000-1500 kWh

Like its sister tugboat, Gisas Power, it was built to a Zeetug30 design with around 30 tonnes of bollard pull and speed of 10 knots. Total fuel costs using an all-electric Zeetug30 were reduced by more than 50% and maintenance costs fell by 79% with the data derived by comparing the Zeetug30 with a similar diesel-powered tug in the shipowner’s fleet.
