 Since Innogy was taken over by RWE in 2002 , the site has been owned by RWE Npower . The only substantial structures remaining are the National Grid and NEDL substations . These buildings will continue to remain and there are plans to extend the National Grid substation . The rest of the power station site is unused brownfield land . The site of the main station buildings is currently covered in crushed concrete , left over from the demolition process . Underground workings , such as tunnels and culverts , also still exist on the site . The coal storage area to the north has been tarmaced and ash settling ponds have been filled with concrete . Some ash mounds are still situated to the east of the site .
