This renewable energy project was developed by Algonquin Power and consists of 26 3.2MW wind turbines on various sites around the island. Morven had completed a number of major civil projects on the Island including the Municipal Drain (1984), Box Culvert Replacements on Front Rd and Stella 40 Ft Rd (2011) and Front Road Reconstruction (2016) when Pennecon Heavy Civil Ltd. approached them to work on the pre-construction phase (early works) of the project.
