Vegetation management cost per mile: benchmarks and calculator
Vegetation management cost per mile is driven mainly by how often each span is worked, how much vegetation is there, how easy the line is to reach and what the rules require. Public figures vary widely, from a few hundred to over forty thousand dollars per mile, because they measure different things. The figures below come only from documents we opened and read ourselves: a 2024 U.S. Department of Energy guide, the study it cites for one row, and annual reports filed with the Kentucky Public Service Commission.
How much do utilities spend on vegetation management per mile?
Each row states what the number covers, the period and where it comes from. Utility names are left out on this page; every source document names them.
| Who / where | Line type | Period | Cost per mile | What the figure is | Source |
|---|---|---|---|---|---|
| 7 Texas utilities | Distribution | 1998–2008 | $3k–$12k | Average cost per vegetation management cycle, per mile, nominal dollars averaged over the period | DOE 2024, Table 1 [1] |
| 7 Texas utilities | Transmission | 1998–2008 | $0.3k–$9k | As above | DOE 2024, Table 1 [1] |
| 3 Maryland utilities | Distribution, transmission and substation supply lines | c. 2013 | $6k | An estimate, not Maryland actuals: the average of more than 180,000 miles of tree trimming at 12 Texas and Florida utilities (2008), applied to Maryland overhead miles | DOE 2024, Table 1 [1]; NARUC/MDPSC 2013, PDF pp. 69–70 [2] |
| 1 Minnesota utility | Distribution and transmission combined | 2018–2020 | $8.7k | Average cost per cycle, per mile | DOE 2024, Table 1 [1] |
| 1 Florida utility | Distribution | 2023–2025 | $11k | Average cost per cycle, per mile, from a storm protection plan (planned, not actual spend) | DOE 2024, Table 1 [1] |
| 1 Florida utility | Transmission | 2023–2025 | $42k | As above | DOE 2024, Table 1 [1] |
| 1 Kentucky utility | Distribution, trees inside right-of-way | 2023 (actual) | $13,917 | Overall O&M cost per unit, per mile cleared; 1,396.6 miles cleared on a five-year cycle | Kentucky PSC filing, Apr 2024, p. 4 [3] |
| 1 Kentucky utility | Distribution, trees inside right-of-way | 2025 (actual) | $12,310 | Overall O&M cost per unit, per mile cleared; 1,643.9 miles cleared; total O&M $22.45 million | Kentucky PSC filing, Apr 2026, pp. 2–5 [4] |
These figures are not comparable 1:1. Some are per mile cleared in one year, some per mile of line per cycle; some are plans, some actual spend; some mix transmission and distribution; and the dollars are nominal, from different years. The DOE guide notes that total program cost also depends on how often the work is done. The same DOE table has two further rows for a second Florida utility that we left out, because we could not check their units against the original filing.
What changes the cost of utility tree trimming?
No numbers here that we cannot source. These are the factors that move a per-mile figure up or down.
Fixed calendar
Every span is worked every few years, whatever its state. Budgeting is simple: roughly one cycle-length fraction of the network each year. The documents above describe cycles of three to six years [1] [2] [4]. The cost: crews also visit spans that did not need work yet.
Measured need
Crews go where measured risk is highest; low-risk spans wait. Whether total cost falls depends on how uneven the risk is across your network and on the cost of measuring every span. We do not publish a savings figure, because it depends on your network.
Remote spans cost more
One Kentucky filing attributes a 2023 field cycle-maintenance cost per mile 20.1% above target partly to 28.8% of the miles cleared being in remote, difficult-to-access areas, together with higher contract costs [3].
Fast growers come back sooner
Fast-growing species can need a mid-cycle visit; the DOE guide gives a Florida example [1]. Vines can dominate in-right-of-way interruptions: about 72.9% of them in one Kentucky report for 2025 [4].
Rules set the floor
Minimum clearances and cycle schedules set by the regulator fix much of the work. Maryland's regulation, for example, required a utility on a four-year cycle to cover set shares of its distribution miles each year [2]. Landowner consent and refusals also limit what can be done [4].
What would monitoring cost on your network?
Plain arithmetic: your inputs times our published list prices. It does not estimate savings, outages or crew hours. LiDAR data collection is included only if you enter your own quote.
Result from your inputs
Not included: high-resolution satellite imagery (bought at market price, only where needed, via the data marketplace), pole image analysis, field work and anything else not entered above. Currency in brackets is a conversion at 1 € = 1.1185 $; the main figure uses the list price for the unit you chose, so miles and km results can differ slightly by rounding.
Vegetation management cost: common questions
How much does utility vegetation management cost per mile?
Published figures range from about $300 to $42,000 per mile, depending on whether the line is transmission or distribution, the period, and what the figure includes. A U.S. DOE guide (2024) lists $3,000–$12,000 per mile for distribution and $300–$9,000 per mile for transmission at seven Texas utilities (1998–2008), and $11,000 (distribution) and $42,000 (transmission) per mile in one Florida storm protection plan (2023–2025). One Kentucky distribution utility reported an O&M cost of $12,310 per mile cleared in 2025.
Why do vegetation management cost benchmarks differ so much?
They measure different things. Some are per mile trimmed in a year, some per mile of line per cycle, some are plans rather than actual spend, and some mix transmission and distribution. Cycle length, terrain, access, tree species, right-of-way width, contract labour rates and the rules in each state also change the number. Treat them as ranges, not as a target for your own network.
Is risk-based trimming cheaper than cycle-based trimming?
There is no general figure that holds for every network, and we do not publish one. Risk-based work moves crews to the spans where measured risk is highest instead of trimming every span on a fixed calendar. Whether that lowers your total cost depends on how uneven the risk is across your network, on your regulator's rules, and on the cost of the data you need to measure every span.
How much does a LiDAR survey cost per mile?
There are two parts. Data collection (the flight or drone survey) is quoted by survey providers and depends on terrain, point density and mobilisation; we do not publish a benchmark for it. Processing the point cloud with our automated LiDAR analysis has a list price of $90 per mile (€50 per km). Flying LiDAR only on the share of the network that satellite monitoring flags keeps the surveyed length smaller than flying the whole network.
What does satellite vegetation monitoring cost per mile?
Our list prices are $9 per mile per year (€5 per km) with quarterly refresh, $14.50 per mile (€8 per km) with monthly refresh and $22 per mile (€12 per km) with weekly refresh. The satellite packages apply from 6,200 miles / 10,000 km of network; smaller or larger networks are quoted. A free demo covers up to 60 miles / 100 km of your own network.
What does the calculator on this page include?
Only arithmetic on your inputs and our published list prices: network length times the package price for satellite monitoring, and the LiDAR processing price times the length you choose to survey. LiDAR collection is added only if you enter your own quote. It does not estimate savings, outages or crew hours, because those depend on data we do not have.
