The Niagara wind farm is the fifth largest in North America. It comprises 77 3.0 MW turbines which provide a combined capacity of 230 MW.
The wind turbines are grouped into ten collector circuits that bring power to substations via a 34.5 kV underground cable. The fibre optic cable will be used to collect and transmit critical wind condition information from each turbine.
Prysmian’s contract was awarded by NCS International for the MV power and fibre optic cables, and Eptcon for the HV cables.
Prysmian will supply 25 km of 138 kV underground cable with aluminum conductor and XLPE insulation and 650 km of 35 kV MV power cables to interconnect the wind farm to Canadian utility Hydro One networks.
Prysmian will also supply the HV outdoor terminations and Click Fit jointing systems along with direct burial fibre optic cable. The medium voltage and high voltage cables will be supplied from Prysmian’s factories in Ontario in Canada and Abbeville in the US.
Scott Roberts, Prysmian’s vice-president of Energy & Infrastructure for North America, said: “This project re-affirms the company’s leading supply position in North America within the power transmission and distribution systems for the renewable energies market.”
