Gan ffurfio Cytundeb Cyd-fenter â'r awdurdodau sy'n ffinio â'r safle, Castell-nedd Port Talbot a Phowys, mae Llywodraeth Cymru'n chwilio am ddyfodol ar ôl glo ar safle sydd wedi'i adfer yn briodol a'i brynu ar y ddealltwriaeth ei fod wedi'i baratoi'n addas ar gyfer adeiladu'r ganolfan brofi. Bydd hynny wrth gwrs yn gofyn am gytundeb â'r perchennog presennol, Celtic Energy.
Forming a Joint Venture Agreement with the preferred site’s neighbouring authorities, Neath Port Talbot and Powys, the Welsh Government is working to deliver a future beyond coaling operations that allows an appropriately restored site, together with a site eventually acquired on the basis it is suitably prepared for the construction of a test facility. This will obviously require an agreed way forward with the current landowner Celtic Energy.
