Sector: Energy

Project Description

The Northeast Power Line Project is a 500kV line between Hanmer TS (Sudbury) and Mississagi TS (Wharncliffe), which equates to 205km in length. The purpose of this transmission line is to reinforce the transmission line system in Northeastern Ontario while supporting the growing electricity demands of industry, businesses and residents. TULLOCH was contracted by HONI to provide land surveying and geotechnical engineering in support of the transmission line design.
