It was renamed Eastern Group under which name it was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index until it was acquired by Hanson plc in 1995, before being purchased by Texas Utilities in 1998.

It subsequently became known as Eastern Group, with offices across the east of England including Norwich,[7] Ipswich,[8] Wherstead Park,[9] Rayleigh,[10][11] Enfield,[12] Bedford[13] and Bury St Edmunds.

[19][20][21][22] Its subsidiary, Eastern Natural Gas,[23] was reported to be making a loss close to £40 million after a big push to grab market share after deregulation.

[28] The bid expired before the Monopolies & Merger Commission completed their investigation, and PacifiCorp were joined by Texas Utilities and Nomura Holdings in a takeover battle.

[36] The Telecom business announced that it had developed its own equipment to use the companies powerlines for telecommunications in July 1998, with a further 550 km of lines being purchased that October.

[37] The Telecom business was sold to NTL in January 1999, and purchased further stakes in North Sea gas fields.

In a separate deal in November 2001 TXU Europe sold West Burton power stations to London Electricity Group for £366 million.

[56] This was followed by the sale of Peterborough and King’s Lynn Combined Cycle Gas Turbine (CCGT) power stations to Centrica in August.

[65][66] Powergen purchased TXU's UK retail businesses for £1.37bn ($2.9bn) later that year, after a takeover battle with SSE plc.

[69] The collapse of the business lead to former shareholders losing £19m, as during the takeover by Texas Utilities they had taken loan notes instead of cash for their shares, which were not secured.

[70] In 2006, artist Rory Macbeth painted Sir Thomas More’s entire novel Utopia onto an old Eastern Electricity building on Westwick Street in Norwich.
