Rising energy prices in the UK have boosted the price of Eggborough's term loan to the 203-206 range. The U.K. power station's term loan was trading in the 153-155 range three months ago. "Electricity prices have moved up. People view Eggborough as undervalued," said one investor. The company's bank debt was trading well below par in the 73-75 range a year ago. British Energy, a nuclear power company, bought Eggborough five years ago.
