At the onset of World War Two, land at Chelveston was acquired by the Ministry of Defence for strategic use as an airfield. It became a fully operational USAF bomber base throughout the War and the subsequent the Cold War until the 1960’s when the MOD decommissioned the runways and most of the infrastructure and reconfigured the site as a radio mast transmitter site which operated until very recently.

The airfield was sold by the MOD in 2005 and the new owners, local employers, seeing the site to be ideal for development as a fully integrated renewable energy park formed Chelveston Renewable Energy Ltd.
