Underground Cable Modernization

The Underground Cable Modernization Program (UCMP) is designed to modernize and increase the capacity of the existing underground transmission cable systems by replacing existing fluid-filled cable with cross-linked polyethylene cable.

This modernization helps mitigate the risk of potential supply obsolescence and reduces the occurrence of unplanned outages which may require the need for emergency replacement or repair.​ This is a more environmentally friendly and widely available technology with a greater life expectancy.

The new polyethylene cable requires less maintenance and minimizes the impact to customers and property owners along the project route.​
