The festival is powered by Aggreko who provide over 27 megawatts of power to the site with 250 bio-diesel generators, run on 60,000 litres of waste vegetable oil (WVO) fuel. The power generated is enough to power the city of Bath and the Pyramid Stage is powered by 4 generators itself. There is 24 km of festoon lighting around the site, also installed by Aggreko. This is run with time clocks so the lights are only on when they are needed, contributing to the festival's green requirements.
