The residential underground line extension estimator is to be used for approximation estimates. It is not intended to determine a design or route, or identify how facilities will be installed on your site. Actual design and advance payment will be determined after you meet on site with a CPI representative.
Underground estimates are not applicable to service alteration, conversions, non-residential line extensions, or any lot where low-voltage facilities already exist to serve your new home.
Trenching and conduits are the applicant’s responsibility and are not included in these cost estimates.
The estimate is calculated based on starting point and distance provided, and may not reflect conditions unique to your site. The estimated path for the power line should be clear, accessible year around, and free of trees and rock.
Other factors that may affect cost include, but are not limited to:
- Street crossing (traffic control, boring across road, or road repair from trenching)
- Obstacles in route
- Concrete or shallow rock
- Steep incline/decline
- Soil Conditions (sandy, rocky, or contaminated soil)
- Right-of-way Permitting
The maximum allowed service wire length is 150 feet. All other distances will be calculated as a primary line extension. The maximum allowed line extension length for this approximation tool is 1750 feet.
