TXU Gets Okay to Buy Britain's Norweb

LCG, Oct. TXU Corp. of the United States was given clearance this morning by British regulators to acquire a regional electric company in northern England in a deal that will make the Texas company the biggest electricity retailer in the United Kingdom.

An arrangement between TXU and the British firm United Utilities for the purchase of Norweb Energi, the regional power retailer, for about $450 million was announced in August. The deal will add about 2.2 million electricity and gas customers to the 3.4 million TXU has through its ownership of Eastern Energy.

Industry savants in Britain have long said that a customer base of 5 million was necessary for a company to be a major long-term player in the UK retail energy market, and TXU is first over the bar with 5.6 million. The company will also become the number two natural gas retailer behind British Gas.
