Installed cost covers what a utility spends to purchase, deliver, and install a utility pole. This cost, however, is not the total cost that a utility will spend over the service life of the pole. Utilities need to factor in the costs after the initial installation to maintain the pole throughout its service life. These could include inspection costs, repair costs, and replacement costs. The total cost of ownership follows that investment across the pole’s entire service life.
The Cost Comparison Shouldn’t Stop When the Pole Goes Up
The price gap between wood and composite poles is at its widest when the comparison includes just the pole purchase price. As an example, a wood pole could cost $500 while the same class and size composite pole could cost $2,500. This represents a 5:1 purchase price gap. The cost to install a single piece of wood pole and a single piece of composite pole is approximately the same. These costs would include transportation to the job site, digging the foundation, setting the pole in the hole, backfilling the foundation, and associated labor. These costs are approximated to be $10,000. Factoring these costs, the installed cost for the wood pole is $10,500, and for the composite pole it is $12,500. The purchase price gap now becomes 1.2:1. But this cost is not the total cost of a pole. The costs to maintain the pole during its service life also need to be considered.
Long-Term Cost Paths, Wood vs EnduraPOLE™
The U.S. Department of Energy’s Utility Pole Maintenance and Upgrades Resilience Investment Guide estimates the average service life of wood utility poles at 30–50 years, with wide variation based on inspection, maintenance, and replacement practices. That variation matters to the procurement decision because wood can follow two different spending paths.
Path A: Fund inspection and remediation to extend service life. The utility carries the inspection, labor, access, treatment, repair, and follow-up costs required to keep poles in service longer.
Path B: Limit remediation and replace the pole earlier. The utility spends less on recurring treatment but brings the next replacement forward. Within an 80-year model, a 30–50-year average service life introduces at least one additional purchase, installation, mobilization, removal, and disposal event.
Wood does not reach the longer end of its service life without considering the inspection and maintenance practices that support it. The utility either carries those ongoing costs or accounts for replacement within the study period.
Composite follows its own cost path. Thursday Poles specifies an 80-plus-year lifecycle for EnduraPOLE™, with no groundline treatment or scheduled retreatment cycle. The Oak Ridge National Laboratory assessment projects a service life exceeding 80 years for modern composite poles manufactured with UV inhibitors.
A Replacement Repeats More Than the Pole Cost
Every replacement reopens the cost of putting a pole into service: transportation, crew hours, equipment mobilization, access, removal, disposal, and site restoration.
Rural territories compound those costs through long travel distances, remote structures, difficult rights-of-way, seasonal conditions, and distance from service centers. The utility buys the entire replacement process again.
Put Decades of Costs on the Same Dollar Basis
Costs across decades need a common financial basis. A purchase today and a replacement in year 40 do not carry the same present value.
The U.S. Department of Energy’s life cycle cost methodology compares alternatives across the same project period and expresses future expenses in today’s dollars. The utility applies its finance-approved discount rate and uses either real or nominal dollars consistently.
An 80-year period places each cost path on the same timeline: wood replacement under the 40-year scenario, recurring inspection and remediation under the 80-year scenario, and EnduraPOLE™ remaining within its expected 80-year service life. Residual value credits the useful service life remaining when the analysis ends.
Run the Comparison With the Costs Your Utility Already Knows
The utility already holds most of the data required for a total cost of ownership comparison. Total cost of ownership = acquisition and delivery + installation + present value of inspection and treatment + present value of replacement + present value of outage and end-of-life costs − residual value
| Cost Factor | What the Utility Already Has | What It Determines |
|---|---|---|
| Acquisition and delivery | Quoted pole price, freight terms, unloading, and storage costs | The starting point of the comparison |
| Installation and access | Crew rates, equipment costs, travel, and average access time | What the initial installation and each changeout cost |
| Inspection and treatment | Inspection intervals, methods, labor, and remediation spending | Which wood cost path applies |
| Replacement | Scheduled and storm-driven replacement records | Whether another pole enters the study period |
| Outage exposure | Outage minutes, restoration records, and assigned outage values | The operational cost attached to a replacement |
| End of life | Removal, disposal, site restoration, and jurisdictional handling costs | The cost of each retirement event |
Wood service life figures reflect published industry averages and vary by decay zone, soil conditions, and maintenance program. EnduraPOLE™ figures reflect Thursday Poles’ published specifications.
Thursday Poles supplies the EnduraPOLE™ service life, maintenance, weight, and handling inputs. The utility supplies the operating history for its crews, equipment, inspection program, and service territory. Together, those inputs produce a result the utility can defend before management and its board.
Compare the Economics, Not Just the Installation
If a utility compares pole materials only through installation, it has not compared the total economics of the poles throughout their entire service lives. Any economic analysis must account for the complete cost path attached to each material to get the total cost of ownership. Contact Thursday Poles to discuss your service territory, replacement program, and EnduraPOLE™ lifecycle inputs.
Frequently Asked Questions
What disposal costs apply at end of life?
Treated wood may be considered to be a hazardous material which carries handling and disposal requirements that vary by state. EnduraPOLE™ is inert and qualifies for landfill disposal. Thursday Poles also accepts EnduraPOLE™ for recycling and supplies a safety data sheet with each shipment.
How should a utility account for outage costs?
Include outage costs when the utility assigns a dollar value to each event. If the utility tracks outage minutes without a financial value, report outage exposure separately. Excluding outage exposure understates the impact of an unplanned utility pole replacement.
How does utility pole weight affect cost?
Wood pole weight varies by species, class, moisture content, and preservative. EnduraPOLE™ specifications list weight by pole length and configuration. The specified weight determines poles per truck, hauling requirements, and the equipment required to reach and set the structure.
