Sarawak Energy launches first solar-powered electric boat

Sarawak Energy has introduced its first solar-assisted electric boat, named ‘Seri Batang Ai’, to support operations at the Batang Ai Hydroelectric Project. The vessel was officially named by Sarawak Premier Datuk Patinggi Tan Sri Abang Johari Tun Openg during a ceremony at Pangkalan Sapi in Kuching.

Measuring 10 metres in length, the boat was constructed by local company Global Fibreglass Industries using an electric propulsion system designed by Sarawak Energy’s R&D team. It is equipped with two 40 kilowatt electric outboard motors, providing a total output of 80 kilowatts, and a 92 kilowatt-hour battery energy storage system. The boat also features rooftop solar panels with a capacity of 3.6 kilowatt-peak.

The vessel can carry up to 12 passengers, reaches a maximum speed of 25 kilometres per hour, and has an operating range of 40 to 50 kilometres. It is intended for dam safety inspections, environmental monitoring, and transporting personnel. The transition to electric propulsion aims to eliminate direct exhaust emissions and reduce noise and vibration to minimize environmental disruption.
