Generating Stations · The site of the project is located in Buckinghamshire, England. It is approximately 2km to the west of Gerrards Cross, approximately 2.5km east of Beaconsfield and approximately 1.5km north of Hedgerley. The site comprises land immediately to the south of the A40 Oxford Road and immediately to the north of the M40 motorway. It has a history of landfill activities and is currently operated by Veolia for the landfilling of inert building waste (albeit the site no longer accepts any forms of waste).
Planning Inspectorate list of nationally significant infrastructure projects (roads, railways, energy, water, waste), October 2026 (OGL). Each is placed at one point, usually the middle of the site; long schemes run well beyond it.
