Today National Grid runs the distribution network business, and SWALEC Contracting is a trading name of OVO Energy.

[6] The business was bought in 1996 for £872m[7] by newly privatised company Welsh Water, which rebranded itself as Hyder.

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.

In September 2000, Western Power Distribution bought Hyder for £565 million, sold Welsh Water and renamed Infralec to WPD South Wales.
