April 28 (Reuters) - Emera Inc ( EMRAF ) and its

subsidiary Nova Scotia Power are addressing a cybersecurity

incident involving unauthorized access to parts of their

Canadian network and servers, the companies said on Monday.

The energy providers discovered the threat on Friday and

took steps to contain and isolate the affected servers, and

prevent further intrusion, they said.

"There remains no disruption to any of our Canadian physical

operations," including Nova Scotia Power's generation,

transmission and distribution facilities, the Maritime Link or

the Brunswick Pipeline, the companies added.

The 145-km (90-mile) Brunswick Pipeline transports natural

gas from New Brunswick, Canada, to an interconnection with the

much longer 878-km Maritimes & Northeast Pipeline near the

U.S.-Canadian border.
