Huge Northeast utility line proposal could reshape power grid, but also threaten renewables

One of the biggest new electric transmission line proposals in decades is turning into a debate over fracking, renewable energy and the future of an aging energy grid.

The $4 billion to $6 billion PPL Corp. project is designed to take electricity generated near Pennsylvania's booming shale gas region and deliver it to New York, New Jersey, and Maryland. That's prompting questions from environmental groups.

Jeff Tittel of the New Jersey chapter of the Sierra Club says the money would be better spent on renewable energy and efficiency projects. He says the group opposes having the line in its state.

Allentown-based PPL says the 725-mile project would increase reliability and save customers money. The company hopes to know more from regulators by the end of the year.
