Thanks to organizations like the Hybrid Truck User's Forum (HTUF), Florida Power and Light is one of the many utility companies to incorporate hybrid technology.
George Survant, director of fleet services for Florida Power & Light, is gearing up to place three diesel electric hybrid utility trucks into service between September and December.
"Depending on the duty cycles, the boom will run up to two hours on the stored electric power, without any noise at all. This same truck will produce 25 kW of export power with 27,000 pound GVWR. We know that this represents excellent potential for other uses while we are working. Right now, we don't know how it will best be used. But in additional to the boom operating and the tools operating, it will produce 25kW of export power," he says.
"This hybrid power comes to us through the hard work and the expertise of our friends at International. They are partnering with Eaton Corporation to bring us the hybrid trucks this fall."
TESTING, TESTING, H-E-V
Florida Power & Light began testing hybrid technology by purchasing Toyota's Prius. Now as they step into the next class of hybrid technology in medium duty trucks, "We haven't really had any difficulties. The trucks we are introducing now are fairly sophisticated trucks, and they are all now beginning to come with telematics," he says.
Telematics is ability to extract data from the truck while it is on the road to find out what the issues are. If every truck in the future has the capability to do diagnostics remotely and monitor the truck's performance, this kind of advancement could not only cut back on service downtime, but also promises more wireless capabilities in the future.
"The ability to go to an environment where we don't have to carry large paper maps to keep track of the distribution pathways--because now all of those things are integrated into our wireless work stations and global positioning networks--will not only reduce our customer response time, but also has helped us make this conversion to hybrid technology," Survant says.
Fuel savings is unquestionably another huge benefit. Survant says that a modest fleet like Florida Power & Light's will burn over four million gallons of fuel annually. "Generally speaking, every nickel spent at the pump translates to about a $200,000 annual impact," he says.
Throughout the process of testing for the best options, there were a few surprises for Survant and his crew. Survant says that when he first started testing HEVs, battery packs literally weighed thousands of pounds. "That sharply curtailed how far you could go because it took a substantial portion of energy used to drive the vehicle around just to haul the weight of the batteries.
"When we weighed the total package to adapt a medium duty truck, it weighs less than 350 pounds--batteries and motor generator included. We were stunned at how much the technology has leaped forward," he says.
MAKING IT WORK
"It is essentially the same truck. We have already gotten a very good service history with it," says Survant. "What is different is the motor generator, and the automated manual transmission that Eaton is providing. Although that is an off-the-shelf product that Eaton is providing, it already has a long successful service history."
Making sure the truck can be serviced is just one maintenance concern. Knowing how long maintenance managers can expect hybrid trucks to last is another.
"We normally would keep one of these trucks 11 -- 15 years, and we have no reason to believe that these hybrids won't be as durable. This truck had to be as reliable as or better than the ones we are buying today," Survant says.
WHY ADOPT NOW?
Despite advantages like fuel savings and emissions, the cost of actually implementing hybrid technology still may seem like a huge risk. Why should maintenance managers choose hybrid technology over other options?
