Nova Scotia Premier Darrell Dexter is staying out of any potential regional spat over the revised $3.2-billion NB Power deal with Hydro-Quebec.
Newfoundland and Labrador Premier Danny Williams now says he's concerned the deal will give Quebec a "stranglehold" over electricity exports from eastern Canada.
The new deal gives Quebec guaranteed capacity on the transmission system, including export lines.
Jennifer Stewart, a spokeswoman in Dexter's office, says although the Nova Scotia premier is aware of Williams's stated concerns, he won't be commenting further until he gets a chance to look at the revised deal in detail.
Stewart says until then Dexter stands by his comments made Wednesday when the deal was announced.
Dexter said it appeared the deal had addressed concerns raised by the Atlantic premiers around access to New Brunswick's power grid.
