According to organisers, Brighton Festival Fringe is one of the largest and fastest-growing open access arts festival in the world and the largest in England, having launched in 1967.
Firefly is to provide a number of solar powered stages as well as supplying all technical infrastructures across Fringe City, which is Brighton's biggest street party and a showcase for new acts.
"This marks a real step forward for the Fringe in terms of its environmental agenda. We want to pay more than lip service to the idea of sustainability, and teaming up with Firefly is a practical way of achieving this," said Fringe executive manager Nick Stockman.
"We also want to help support local enterprise so it's great to be able to work with a Brighton and Hove success story like Firefly."
