The premiers of the four Atlantic provinces have renewed a pact to act together on energy development, particularly on projects that could wheel energy beyond their borders.

A statement issued by the premiers — Darrell Dexter of Nova Scotia, Shawn Graham of New Brunswick, Robert Ghiz of Prince Edward Island and Danny Williams of Newfoundland and Labrador — says the provinces will co-operate on "an integrated and collaborative Atlantic Canadian energy system," including projects to export energy to other jurisdictions.

The premiers are all currently attending the annual Conference of New England Governors and Eastern Canadian Premiers.

The agreement comes as energy issues have been at the fore in the region. In New Brunswick, Areva — a French energy conglomerate — is promoting a second nuclear reactor, while Williams has been seeking the support of other premiers to move power from the proposed Lower Churchill hydroelectric project in Labrador through the Maritimes.

"All four Atlantic Canadian provinces have been working together on a range of energy issues through the Council of Atlantic Premiers, and look forward to building on that work in conjunction with the federal government through the Atlantic Energy Gateway Initiative," the statement said.
