In 1963, Aberthaw "A" Power Station officially opened, followed by the "B" station in 1971; construction had necessitated a local diversion of the River Thaw and the remnants of the old port diminished. Beyond the conversion of the former mission hall and a number of former agricultural buildings to residential use, East Aberthaw itself, however, has undergone little development. The "A" power station was demolished by July 1998 and the "B" station was closed on 13 December 2019, when decommissioning commenced.
