Washington State Utility Likes the Liquid for Its Superior Range:
Has Forged a New LNG Supply Agreement with Clean Energy Fuels
And Is the Lead Taker of LNG-Fueled Ford F-550 Trucks by World CNG

Seattle-based Potelco continues to affirm its commitment to liquefied natural gas as a fleet fuel, acquiring additional LNG service vehicles and notching a deal with Clean Energy Fuels for supply. The utility is the lead customer for LNG-fueled Ford F-550 trucks, with two in hand and 25 more on order from upfitter World CNG. updated March 27

World CNG is using 119-gallon (approximately 60 diesel gallon equivalent) fuel tanks from Taylor-Wharton on the vehicles it prepares for Potelco, giving them unusually long reach. World CNG is responsible for the utility’s Ford F-550 trucks and for Potelco’s newer LNG-fueled Freightliner trucks.

To maintain flexibility, Potelco operates two mobile Orca fueling units by Chart Industries. They are kept stocked by Clean Energy, and bring fuel to Potelco crews where it’s needed.

Clean Energy is supplying Potelco from a temporary station as a permanent site developed, says Clean Energy VP Chad Lindholm. “All fuel for Potelco is directly delivered from our temp station into their two Orca trucks,” he told F&F.

Potelco currently has 35 bucket and 35 digger derrick trucks operating on LNG, all of them on Freightliner M2 112 chassis and powered by 8.9-liter ISL G engines by Cummins Westport. Forty of them – 20 bucket and 20 digger derrick – have iCE Pack LNG fuel tanks from Westport (F&F, December 2, 2014). The two Orca fuelers have Westport iCE Packs too.

Thirty of Potelco’s newer trucks – 15 and 15 bucket and digger – have more economical LNG tanks from Taylor-Wharton installed by World CNG. Ten more are on order: five and five bucket and digger.

First of Their Kind?

Also in hand are two Ford F-550 chassis work trucks with LNG fuel systems by World CNG using Taylor-Wharton tanks – believed to be the first of the type to operate on LNG. They have 6.8-liter gaseous-prep Ford V-10 engines, and 25 more are on order. Five will have Altec “squirt boom” aerial lifts, says Potelco fleet manager Steve Steedley, and 20 will have standard service bodies.

“Nobody has buckets, nobody has diggers, and nobody has F-550 one-tons that run on LNG,” Steedley told F&F.

Also on order, and also with LNG fuel systems by World CNG, are eight five-yard FL 112-chassis dump trucks with ISL G engines, and two Freightliner 114SD-chassis 15-yard dump trucks with 11.9-liter ISX12 G engines from Cummins Westport.

Clean Claims an Exclusive

“We’re the exclusive fuel provider,” says Clean Energy’s Lindholm. “We anticipate upwards of half a million diesel gallon equivalents per year” of LNG for the utility, he says. Clean Energy is getting LNG from Intermountain Gas in Boise, Idaho, Lindholm says, and anticipates sourcing LNG from FortisBC in Canada as well.

Steedley is slated to speak at the Spotlight on Waste Disposal, Construction Fleets, and Work Trucks session on at ACT Expo on the afternoon of Tuesday, May 5. ACT Expo 2015 takes place May 4-7 at the Kay Bailey Hutchison Convention Center in Dallas, Texas.
