Pacific Gas & Electric adds liquid natural gas trucks
to its service fleet
Pacific Gas and Electric Company (PG&E) announced
that it has added five Class 8 heavy-duty liquid natural gas (LNG) trucks
to its alternative fuel fleet. PG&E is the first utility in the nation
to put the Kenworth T800 LNG-powered trucks into service.
The effort is part of the company’s commitment to reduce its environmental
footprint and improve California’s air quality.
PG&E purchased the Class 8 heavy-duty trucks from Bay Area Kenworth
as diesel units and collaborated on the upgrade to liquid natural gas
operation with Kenworth and Westport Innovations, Inc.
The fuel system developed and manufactured by Westport and called High
Pressure Direct Injection (HPDI), uses a small amount of diesel to ignite
the natural gas in the engine and provides diesel-equivalent torque,
horsepower and a range of 400-450 miles. The result is reduced NOx, particulate
matter and greenhouse gas emissions and less reliance on diesel fuel
by running the cleaner LNG fuel.
The LNG-powered trucks are based at PG&E’s Fremont service warehouse
from where all the utility’s supplies are shipped and are being put into
service for routes to Fresno, Marysville, Ukiah and Templeton. Four of
the Class 8 LNG trucks will be used for two shifts per day, representing
approximately 800 miles per day per truck. Using LNG will cut the fuel
costs for these trucks by approximately 50 percent. The fifth LNG truck
serves as a customer demonstration truck to educate PG&E’s large
trucking customers about the economic and environmental benefits of LNG-powered
PG&E operates 36 natural gas fueling stations throughout northern
and central California, 27 of which are open to the public.
The new LNG-powered trucks fuel up at PG&E’s Fremont Service Center
from an above-ground LNG fueling system.
