Walden microhydro install — 1.8 kW Pelton on a 220-foot head
Off-grid retrofit on a 1968 hill farm. Replaced a worn-out genset with a continuous-baseload Pelton runner cut from the brook above the house.

Farm electrical, the way it actually gets done.
A worker-owned crew in Hardwick, Vermont. We rewire 1850s farmhouses, pull service to milking parlors and sugarhouses, and put in microhydro for hill places that grew up without grid power. Twelve years on the same trucks.
From the masthead
Twelve years of service calls between Hardwick and the Quebec line.
Lamoille River Wireworks is five worker-owners and a service van with 184,000 miles on it. We started in 2014 in a cinder-block shop behind the Center for an Agricultural Economy's Yellow Barn, doing 200-amp upgrades for the dairy farms whose electrician had retired and not been replaced. Twelve years later we still pull most of our work out of a 40-mile circle around Hardwick — Greensboro, Craftsbury, Walden, Cabot, Wolcott, Stannard, Glover, Albany.1
The work is unglamorous. It's 200A service drops to barns whose meter base hasn't been replaced since the Eisenhower administration. It's knob-and-tube remediation in farmhouses where six generations of owners have re-fed the original 1923 panel one extension cord at a time. It's sugarhouse power — vacuum pumping rigs, RO units, evaporator hood fans, the kind of intermittent four-week-a-year load nobody designs for. And it's microhydro and off-grid solar for the hill places that never got a service drop because the line wouldn't have penciled out.
We work to NFPA 70 (the National Electrical Code) — including the agricultural-buildings provisions of Article 547 — and we file every job with the Vermont Division of Fire Safety. We're not the cheapest electrician you can find. We are the one who will still take your call in February when the milkhouse heater trips a breaker at 4:30 in the morning.
"Knob-and-tube isn't unsafe because it's old. It's unsafe because it's been re-fed five times since 1923 by people who didn't know what re-feeding a thing meant." — Marya Buchholz, founder, in April: Mud-Season Service Calls
Job board · Eight numbered job-types
What we get called for, in order of how often.
Every job we take fits one of eight numbered categories. The job code is what we write on the work order, the invoice, and the field-log entry — so a customer reading a logged entry can match it to a job-type page without guessing. New customers usually ask for a J-01 or a J-04 first.
J-01 / SERVICE

J-02 / DAIRYMilking parlor wiring

J-03 / SUGARSugarhouse power
RO units, vacuum-tubing pumps, evaporator hood & bake-out, head-tank floats, sap-line monitoring.
J-04 / HERITAGEKnob-and-tube remediation

J-05 / HYDROMicrohydro & off-grid solar

J-06 / SURGELightning protection & surge mitigation

Field log · Most recent four
What we worked on this winter and spring.
The field log is what an electrician would call a job book. It is an entry per finished job, dated, with the load calculations we did, the parts we used, the route the conduit took, and what we found that surprised us. We publish a sanitized version of every entry — without the customer's name unless they've signed off — because we figure if you're going to hire us you want to see the work.
Cabot Hill knob-and-tube remediation
1851 cape, six previous re-feeds. Pulled NM-B through plaster cavities, AFCI changeout, three two-way switches restored.
East Craftsbury sugarhouse evaporator wiring
New 4×14 oil-fired evaporator. Three-phase 240V to vacuum, hood fans, RO booster, head-tank float, perimeter heat-trace.
Greensboro Bend dairy panel rebuild
52-cow tie-stall barn. 320A meter base & main, equipotential plane re-bonded, milk-house GFCI to NEC 547.
Almanac · Selected entries
Notes on the work, by the season it happens in.
Almanac entries are how we track what we keep relearning every year. Why power quality goes sideways during the sap run. Why the mud-season call list looks the way it does. Why a January cold-load isn't a summer cold-load with extra steps.
If you've ever wondered why your sugarhouse vacuum keeps tripping when a third farm down the line is also running their RO unit, the March entry answers that.
March
Sap-run power quality on the rural feeder
When five sugarbushes within a quarter-mile fire up their evaporators on the same day, the local 7.2 kV branch starts sagging. Here's what to expect, and why a soft-start is not optional.
January
Cold-load planning for hill farms
Why a 200A panel that has run a tie-stall barn for thirty Januarys can fail in its thirty-first — and what to ask your electrician before you say yes to the changeout.
Crew · Five worker-owners
A small co-op, not a big shop.
Lamoille River Wireworks is a Vermont worker cooperative under 11A V.S.A.. Five of us own equal shares; we take turns on dispatch. Hourly rate goes up only when our cost basis does, and we publish what we charge on the rates page.
Visit · By appointment most days
Drop by the shop, or book a service call.
Our shop is on the South Main side of Buffalo Mountain Co-op, in the second-floor space above the bike repair. We're walk-in if the door's open and we're not on a job; otherwise we work by appointment. Service calls inside the 40-mile radius (Hardwick to roughly Lyndonville, St. Johnsbury, Morrisville, Stannard, Cabot) get same-week scheduling outside of mud season; emergencies any hour.
