With more than 775 vehicles – ranging from plug-in hybrids to bucket trucks – OUC’s fleet logs more than 4.7 million miles annually. So, on the road to reducing our carbon footprint, we’re using alternative fuels, purchasing more hybrids and even recycling automotive products to help our environment.
Embracing fuel-efficient technology as a commitment to green initiatives, OUC was the first municipal utility in Florida to acquire a plug-in hybrid that gets up to 99 mpg. Today, we have 11 all-electric vehicles in our fleet and 42 hybrid vehicles.
To support our fleet and the needs of our customers, OUC has installed more than 150 electric vehicle (EV) charging stations in our service area and has innovative rebate options for both residential and commercial customers to install more.
For our linemen out in the field, we have four hybrid bucket trucks and one auxiliary battery system to operate the aerial tower hydraulics. Bucket trucks are a promising application for hybrid technology since much of the vehicle’s work is done when stationary. The hybrid diesel-electric system allows the main engine to be turned off while crews operate entirely off the battery.
Adding New Fuels to the Mix
As part of an overall plan to reduce emissions in our fleet, OUC has begun using “B20” – a blend of 80 percent petroleum diesel and 20 percent biodiesel – a clean-burning alternative fuel made from new or used vegetables oils and animal fats, including recycled cooking grease. Compared to petroleum diesel, biodiesel produces lower emissions, which is better for the environment. B20 has been integrated seamlessly into our fueling system without any changes to vehicles or fuel storage and distribution equipment.
Since 2008, more than 1.4 million gallons of B20 have been purchased – and the reduction in diesel fuel has reduced OUC’s carbon footprint by 44 metric tons of CO2e (carbon dioxide equivalent). Biodiesel is currently used at OUC’s Pershing Fleet Center, and we plan to expand its use to our Gardenia site.
OUC is also in the process of installing two new 10,000 gallon fuel tanks at its Pershing and Gardenia Operations Centers. These tanks will store E85 fuel. OUC currently has approximately 50 new vehicles coming next year that will be able to utilize this fuel.
Environmentally Friendly Policies
OUC’s Fleet Division has incorporated a number of eco-conscious policies. We use earth-friendly products and take special care to dispose of contaminated fuels according to environmental standards. Tires, batteries and oil filters are recycled through vendors, while Freon, antifreeze and motor oil are handled on site. OUC recycles about 20,000 gallons of used oil each year.
We also have a vehicle idling policy that requires the engine to be turned off after five minutes. Diesel engines use about one gallon of fuel per hour when idling, so this policy saves about $4 per hour per vehicle.
Water is recycled, too – thanks to mini-water treatment plants and wash racks at the Pershing and Gardenia facilities that keep OUC vehicles clean.
