The trust originated from a study by Sussex Chamber of Commerce in 1998 which considered the needs of engineering companies in that region. The investigation revealed low levels of interest in science, technology, engineering and mathematics (the so-called STEM school subjects).
The Greenpower project started in 1999 to encourage students to design, build and race their own electric race cars within professionally drafted specifications and only a small helping hand from experienced adults. Events were organized for weekends at major motor circuits around the UK to facilitate attendance from the general public. Circuits included (and still include) Goodwood, Castle Combe and Dunsfold (top gear test track).
Greenpower claims that it now works with 500 schools providing events around the UK. Its Headquarters are at Fontwell in Southern England and Greenpower national events were run at the nearby Goodwood Motor Circuit whose owner is a Patron of Greenpower. Beginning in 2015 the International Final is held at Rockingham Motor Speedway in the middle of October as a two day event, and attracts some 170 cars from all over the UK and Ireland with a small number of entries from international teams in America, Poland and South Africa. The Corporate Challenge attracts entries from large companies and universities as far away as Poland, up to 2012 this had been held at Goodwood or Silverstone but in 2013 was amalgamated with the Final of the F24 championship at Rockingham.
On 30 June 2014, Greenpower announced a partnership with the FIA's Formula e racing series, running a support race for schools during the formula e race weekend.
All Greenpower classes use a 24V, 240W Framco motor and pairs of 12V REC36-12 or YPC33-12 AGM batteries. These batteries are selected to be reasonably easy to lift, leak-proof and their discharge characteristics determine how fast the cars can go. The motor and batteries are sealed and cannot be modified.
