The regulatory body is tasked with evaluating the proposal by utility company Emera (TSX:EMA) to build a subsea cable — known as the Maritime Link — that would ship power generated in Labrador to Nova Scotia.
The board has been asked to decide whether building the 170-kilometre cable represents the cheapest long-term alternative for the province's electricity users and whether the $1.5-billion project meets requirements governing the release of greenhouse gases and air pollutants.
If the development goes ahead, it is estimated it would provide about 10 per cent of Nova Scotia's power needs.
The board held hearings on the project this spring.
Note to readers: This is a corrected story. A previous version said the subsea cable was 180 kilometres.
