Dunbar Grammar School won the Best Overall Project Award at the recent Go4SET Celebration and Assessment Day (CAD) held at Heriot Watt University.
The judges selected Dunbar Grammar for their outstanding work on the use of biomass as a source of renewable energy and the team were presented with a trophy and a cheque for £250 by Martin Grey from Viridor.
The team will now go forward to the Go4SET Scottish Final which will be held in the Scottish Parliament in May.
The CAD event and awards were sponsored by Viridor.
Councillor Paul McLennan, leader of East Lothian Council said: “As a former pupil of Dunbar Grammar School I am absolutely delighted that the school have won such a prestigious award.
“I commend the pupils for all their hard work and wish them luck in the Scottish Finals.
“It’s an important event for skilling our young people for the future.”
Dunbar Grammar were supported by EDF Energy Torness Power Station during the project.
