The Wall Street Journal reported that Fidelity Management & Research agreed to back the chapter 11 plan of Dallas-based Energy Future Holdings.

The Journal said Fidelity holds Energy Future debt, and will join a group that is attempting to buy Energy Future’s electricity transmissions business, Oncor, according to statements made by an attorney for advocates of the restructuring plan in the U.S. Bankruptcy Court in Wilmington, DE.

The Journal said the sale of Oncor is essential to the restructuring plan as proceeds from the sale will be used to repay creditors.
