Cable reels in New Mexico: wind lines, oil fields and long roads

SunZia: wind farms and a line to Arizona

SunZia is the project that defines New Mexico's grid work this decade. Pattern Energy describes it as 3,650 MW of New Mexico wind carried west on a plus or minus 525 kV HVDC transmission line of more than 550 miles to Arizona and the wider western grid. The wind farm side sits in central New Mexico; the line runs south-west across the state and into Arizona.

A wind farm of that size is a reel factory in its own right. Each turbine string is joined by buried medium-voltage collection cable, which comes on large nailed wood reels, and the collection system feeds substations that take their own feeder and control cable. When a phase is energized, the contractor's laydown yards hold piles of empties, often far from any town. Those piles are what we want to hear about.

• Collection cable reels: often large, 66-inch flanges and up, heavy and few to a trailer.
• Substation and control cable reels: 36 to 60 inch flanges, easier to resell.
• Fiber reels from turbine and substation communications: small and mid sizes.
• Conductor reels from the overhead line: often steel, which we don't trade.

The Permian Basin corner

South-eastern New Mexico, around Hobbs, Carlsbad and Artesia, sits on the western edge of the Permian Basin. Oil and gas work there uses a lot of power cable for pumps, compressors and well pads, and the reels it comes on collect at service yards along US-62 and US-285.

Southwestern Public Service, the Xcel Energy company serving eastern New Mexico and the Texas Panhandle, sold 11,607,263 MWh at retail in New Mexico in 2024, more than any other utility in the state by EIA's count. Its New Mexico territory takes in the oil field around Hobbs and Carlsbad. Line extensions to new well pads and substations for oil field load keep SPS contractors pulling cable, and the empties from that work often pair well with lots from the Texas side of the basin.

Albuquerque, Santa Fe and Las Cruces

Public Service Company of New Mexico, PNM, serves Albuquerque, Santa Fe and much of the north-central state. El Paso Electric serves Las Cruces and the Mesilla Valley. The City of Farmington runs its own utility in the Four Corners. Between them they account for most of New Mexico's metro distribution work, and the reels from it are the familiar mid sizes: 42 to 66 inch flanges from URD and feeder, and small building wire reels from commercial jobs.

Albuquerque is where I-25 and I-40 cross, so it is the natural gathering point for New Mexico reels. Las Cruces sits where I-25 meets I-10, close to El Paso, and a Las Cruces lot is often closer to Texas buyers than to Albuquerque ones.

Distance is the price

New Mexico is the fifth-largest state by area and one of the emptiest. Freight is paid by the trailer, and in a state this size the freight on a part load can exceed the value of the reels. A van of 36-inch reels holds about 200, per Sonoco's packing guide, so the cost per reel is small. A trailer of 84-inch reels holds about 9, so each one carries a large share of the trip.

We say this plainly because it decides whether a small, remote lot is worth selling now or worth holding until a second lot on the same road is ready. A wind site near Corona and a substation job near Clovis might share a trailer. A single reel lot near Gallup may need to wait for company.

Fiber for a rural state

NTIA's June 2023 table set New Mexico's BEAD allocation at $675,372,311.86. Unserved locations are spread over pueblos, tribal lands, ranch country and small towns, often many miles apart. Fiber routes that long use a great many reels, and crews need clean empties for cut lengths and re-spooling. The rule to remember is the bend limit: NEMA WC 26 sets the drum for fiber at no less than 20 times the cable's outside diameter, never under 12 inches.

Dry storage and sun damage

New Mexico's dry air protects reels from rot, and a reel stored years in Albuquerque often has firm staves. High-altitude sun is harder on flanges, drying the plies until they check and split. Spring winds on the eastern plains can roll light empties left on their sides. Stand them on their flanges, chock them, and send us photos of both flanges so we can judge the plies.

What the desk needs

1. 01

   Location first

   Nearest town and road. In New Mexico, location decides the freight more than anything.

2. 02

   Sizes and counts

   Flange x traverse x drum for each size, from the reel stencil, with a count.

3. 03

   Condition

   Photos of the pile, a stencil per size, and close shots of flange splits or torn drive holes.

4. 04

   Loading

   Forklift, telehandler, dock or none, and whether a 53-foot trailer can get in.
