UNIONDALE, NY - The Long Island Power Authority (LIPA) is integrating the first two hybrid trucks into its service fleet.
"The addition of these two new trucks reinforces my commitment to LIPA's continued investment in energy efficiency and clean renewable technology," said LIPA President and CEO Kevin Law. "These trucks will provide many green benefits including: improving our air quality, curbing noise pollution, increasing energy efficiency and providing financial savings for our customers."
Each new vehicle is estimated to save 35 to 55 percent of fuel, based on similar prototype vehicles. With an annual consumption of 1,970 gallons of diesel fuel, at $3 per gallon and an approximate minimum reduction of 35 percent in fuel, LIPA expects to save 1,400 gallons of fuel per year for total savings of $4,200 dollars. Moreover, CO2 emissions will be reduced by 10-15 tons per truck annually; resulting in $500 to $750 in carbon offset savings, according to the agency.
The new trucks are equipped with the same size engine as a conventional truck and will operate like a normal hybrid vehicle. However, a key efficiency component of these trucks begins when the aerial bucket operates with the engine completely off, while workers use the bucket to perform day to day operations. Furthermore, the engine will also kick off when the vehicles are idling, reducing fuel usage and exhaust emissions.
The hybrid system also features regenerative braking. As the brakes are applied, the energy is captured and used to charge the lithium-ion battery system. This battery is used to operate the boom, (the part of the truck used to lift workers), for up to two hours with the engine off.
More than 25 percent of LIPA's 607 vehicles contain a clean energy component including, gasoline hybrids, bio-diesel, and compressed natural gas. LIPA envisions continuing to add more energy efficient vehicles as some of the older trucks and cars in the service fleet need replacement.
