Sustainability is a goal for many utility fleets, but there may not be enough money in the budget – or full stakeholder support – to do all it takes to meet that goal, including overhauling infrastructure, adding new vehicles to the fleet and training staff.
That’s where biodiesel can come into play.
“Biodiesel can be burned in any vehicle, and you don’t have to make infrastructure changes,” said Patti Earley, fleet fueling operations specialist for Florida Power & Light Co. “The fuel tanks don’t need modifications. The fuel equipment isn’t different. It’s very easy. And with biodiesel, you can burn B20 one day and use ultralow sulfur diesel the next without any problems.”
Biodiesel – a fuel made from feedstocks including recycled cooking oil, soybean oil and animal fats – typically is named based on the percentage of biodiesel found in a particular blend. B20, for instance, is 20 percent biodiesel and 80 percent petroleum diesel; it also is the most common blend. Florida Power & Light has used biodiesel since 1999, up to B35. The utility runs all of its diesel equipment on biodiesel and has logged more than 150 million miles.
Proving just how seamless the conversion is, Earley noted that crews from other utilities who have helped out in storm recovery efforts have used biodiesel from Florida Power & Light and “weren’t aware” they were doing so.
