HALIFAX -- The Nova Scotia government is in talks with an Irish firm about adding another berth at a tidal energy research centre in the province.

Energy Minister Andrew Younger says DP Energy is interested in installing a 4.5-megawatt tidal stream demonstration power plant.

It would be located at the test site for the Fundy Ocean Research Centre for Energy in Parrsboro.

The government says there are four other tidal energy projects planning to test new technologies at the research centre, which is also known as FORCE.

In March, the government announced $4 million to help increase the electrical capacity at FORCE by allowing newer devices to connect to the grid.
