The coal-fired station was originally built and operated by the South Wales Power Company Limited to supply electricity to munitions factories during the Second World War. It was completed by the post-nationalisation British Electricity Authority in 1951, and was later operated by the Central Electricity Generating Board.

This brief starts where responsible research should: with the source description of “Llynfi power station” as former coal-fired power station. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as former coal-fired power station. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jun 12, 2026. The linked authority identifier is Q104847834. Authority coordinates are 51.570, -3.611. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1943, 1977 and 1951.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
