SWALEC was an electricity supply and distribution company in South Wales, established in 1989 following the de-regulation of the electricity supply industry in the United Kingdom. The business has seen several changes of ownership from 1996, and the SWALEC brand has been used for retail gas supply as well as electricity. Today National Grid runs the distribution network business, and SWALEC Contracting is a trading name of OVO Energy. The name SWALEC is a syllabic acronym of 'South Wales Electricity'.[1]
The SWaEB was responsible for the purchase of electricity from the electricity generator (the Central Electricity Generating Board from 1958) and the distribution and sale of electricity to customers. The key members of the Board were: Chairman W.D.D. Fenton (1964, 1967), Deputy Chairman H. Pryce-Jones (1964, 1967), full-time member William E. Richardson (1964, 1967).[2]
The number of customers supplied by the Board was:[3][4]

Formation
SWaEB was privatised in 1989[5] as South Wales Electricity, one of the regional companies created by the Electricity Act 1989. The company soon began to use the SWALEC brand.[6]
Purchase and breakup
The business was bought in 1996 for £872m[7] by newly privatised company Welsh Water, which rebranded itself as Hyder. The business plan was to make significant logistical savings by combining the field activities of electricity and water supply operations by co-locating in fewer offices and operational depots.
In 1997 SWALEC Gas was set up to take advantage of the deregulation of the gas market in the UK which took place in stages from 1997 to 1998. An advertising campaign was launched featuring Wimbledon F.C. and Wales footballer Vinnie Jones.
Hyder encountered financial difficulties and in February 2000 the retail electricity and gas business under the SWALEC brand was sold to British Energy for a reported £105m. The sale included the SWALEC retail brand, whilst Hyder retained the SWALEC electricity distribution business (i.e., running the electricity network) which was renamed Infralec.
SSE continued to use the SSE SWALEC brand name for the supply of electricity and gas in Wales. Following the sale of SSE's retail business to OVO Energy in 2020, SWALEC is a trading name of OVO.[8]
From 1992 to 2013 SSE was the sponsor of Wales WRU Challenge Cup, and the SWALEC name was attached to a range of league competitions and trophies administered by the Welsh Rugby Union.[9]
