A fight for the power transmission company Oncor is threatening to derail Energy Future Holdings’ plans for a quick trip through bankruptcy court, the Dallas Morning News reported today. More than two months after the Dallas power company filed for chapter 11 protection from its $40 billion in debts, it is trying to get through court a proposal that would effectively hand its subsidiary Oncor to a group that includes Dallas energy magnate Ray L. Hunt and the state teacher’s pension fund. But EFH is facing substantial opposition from creditors who say the plan is allowing excessive returns to favored creditors. One group of opposing creditors has partnered with Florida-based NextEra Energy to produce a counter offer that would give NextEra control over Oncor. Bankruptcy Judge Christopher Sontchi is expected to rule on the EFH proposal later this week.
