What if you could convert the majority of your fleet to run on a cleaner-burning, renewable fuel with minimal capital investment. Would you do it?

According to NTEA’s 2019 Fleet Purchasing Outlook, a growing number of fleet professionals are saying they would, with survey participants naming biodiesel as their top alternative fuel choice – and their top choice for future interest.

Think of biodiesel as the low-hanging fruit for fleets to make a significant dent in their green initiatives without breaking the bank. That's because the fuel is relatively easy to get, and biodiesel blends up to B20 (20% biodiesel and 80% petrodiesel) can be used in most diesel engines without modification. Compared to petrodiesel, B20 reduces carbon emissions by 16% on average, according to the National Biodiesel Board. And you can use biodiesel in conjunction with your fleet electrification efforts, such as with hybrid-electric diesel trucks.

Suez North America is an environmentally friendly water utilities company, providing water and wastewater services as well as recycling and waste recovery services to almost 8 million people in North America. Known for placing sustainable environmental practices at the forefront of their operations, Suez employs innovative strategies to shrink their environmental footprint. The corporate headquarters for Suez’s North American operations are found in Paramus, New Jersey. In northern New Jersey alone, Suez serves 800,000 people with clean, sustainable water, while preserving the local waterways.

Bruce Ottogalli, transportation manager, oversees Suez’s fleet in New Jersey and New York. As the company’s only transportation manager, he is responsible for maintaining, servicing and updating the fleet’s work trucks – an integral part of Suez’s operations.

“As a sustainable company, the biggest thing for us is to have a limited environmental footprint with the vehicles, curb our carbon footprint and go green,” Ottogalli said. “We’re limited in our area as we can’t use propane or natural gas, because the suburban areas we serve don’t have that kind of fuel to fill our trucks.” Because the fleet’s vehicles must be powered by diesel or gas, Ottogalli has had to find other ways to follow the company’s green mandate.

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.

If you’re looking to green your fleet in a way that’s good for both the environment and the business, you don’t have to go about it alone.

That’s the message of Clean Cities (https://cleancities.energy.gov/), which was formed in 1993 by the U.S. Department of Energy and, today, has nearly 100 local coalitions that bring together businesses, fuel providers, vehicle fleets, government agencies and community organizations all pursuing the same goal: cutting petroleum use in transportation. Some of the program’s recent utility fleet success stories include Pacific Gas and Electric, Public Service Company of New Mexico and Atlantic County Utilities Authority in New Jersey.

The idea behind Clean Cities is that investing in green technologies at a meaningful scale can be a high-risk, high-cost endeavor for most fleets to shoulder alone. But what if you could connect with other fleet managers and experts who have real-world experience with vehicle electrification, natural gas, propane autogas, biodiesel or whatever technology you’re looking to deploy?

You could significantly reduce risk and tap into economies of scale that make your green initiative more affordable – and more compelling to the business.

It’s Clean Cities that helps make those connections happen at the local level and across the country, said Dennis Smith, Clean Cities national director, who, prior to joining the program in 2001, served as director of energy services at Atlanta Gas Light Co., a large Atlanta-based utility.

If your fleet operates plug-in electric vehicles (EVs) – or is planning to do so – there’s an emerging technology you’ll want to put on your radar that could impact your vehicle selection and charging infrastructure decisions within the next year or two.

It’s wireless EV charging, which proponents believe holds the key to widespread transportation electrification.

That’s because one of the friction points of operating EVs is the inconvenience of charging with a conventional cord and plug-in system, said David Schatz, vice president of business development and sales for WiTricity (http://witricity.com), a firm that develops wireless charging systems for EVs, headquartered in Watertown, Mass.

Schatz cites a major automaker’s internal study that found that 70 percent of all plug-in hybrid electric vehicle (PHEV) owners never plug in and opt for fueling only with gas because of the “inconvenience” of plugging in their vehicle.

The idea here is that if you cut the cord, you make EV charging more acceptable to a larger market because you’re not forcing users to change their behavior. “PHEV and EV drivers simply park over a charging pad in their garage, or at work, or at a shopping center and charge up with no hands, no effort,” Schatz said.

Regardless of how cutting-edge a type of technology may seem, getting buy-in from prospective users often requires a pragmatic approach: They need to be convinced it works.

Such is the case with anti-idling technology. Today’s tools – aimed at reducing emissions and wasted fuel – include automatic shut-off systems, real-time alerts and plug-in hybrid vehicles that allow systems to work when the engine is off. But the only way utility fleet operators will fully embrace such tools, experts say, is when they grasp the difference that can be made, in terms of both the environment and their organization’s financial bottom line.

“It’s very spotty,” said Linda Gaines, transportation system analyst at Argonne National Laboratory (www.anl.gov) and a recognized idling authority. “You’ll go to some meetings and talk to some fleets, and they’re on board. It’s like your job is done, and the information is all out there. A lot of states have regulations, and it seems like we’ve made a lot of headway. And then you go and visit some company and see how far there still is to go.”

Gaines referenced one organization that is interested in idle reduction and went through the process of installing telematics, but, she said, was still “absolutely shocked by how much idling their trucks were actually doing. I think that’s not an unusual occurrence. Just by sharing that information with the drivers, without any kind of threat or any kind of reward, either way, just by being aware, the drivers reduced their idling by some very significant fraction.” That fraction was near 30 percent.

Unnecessary idling is still the bane of many utility fleets, and while not every fleet wants to turn off vehicle engines at job sites, some new and updated technologies are offering improved auxiliary energy options.

In March, Altec (www.altec.com) introduced JEMS 4, the latest version of its Jobsite Energy Management System, which offers integrated engine-off cab heating and cooling and an on-demand, electrified PTO for hydraulic power.

The anti-idling system is automatic; as soon as the truck is put in park or neutral, the engine shuts down. “In this way, idle mitigation is not something the operator has to think about,” said Mark Greer, Altec market manager.

JEMS 4 relies on a new generation of lithium-iron-phosphate batteries, which offer improved thermal and chemical stability – safer chemistries – than the previous cobalt-based lithium-ion batteries. Also, the battery pack is about half the weight of previous versions and takes up about half the space, Greer said. (For more information, see the “Better Batteries, Lower Prices” sidebar at the end of this article.)

The core of JEMS is the idle and power management system from Cullman, Ala.-based ZeroRPM (www.zerorpm.com). In addition to the controller, components include lithium-iron power and energy modules to power booms, buckets and systems, said Evan Miller, vice president of sales and marketing. ZeroRPM also offers a stand-alone AC unit powered by the energy modules, and for organizations with enough roof space, the company has a solar-powered option to charge the batteries.

The benefits of advanced telematics systems are widely known today. They can help fleets deploy resources more efficiently, increase the number of jobs completed each day, reduce costs and more. But even so, having an awareness of these benefits is often not enough to convince fleet managers that an investment in telematics is worthwhile. To discover if a fleet-wide system will truly deliver value, fleet professionals must first take the time to identify their business challenges, set criteria and pilot different systems.

To identify the business problems a telematics system could potentially solve, fleet professionals should study their fleet’s productivity, fuel and labor expenses, safety concerns and quality of customer service. The fact is that a number of utility fleets are unable to answer important questions about these operational areas that make a big impact on a utility’s bottom line. Gaining a better understanding of the primary challenges the fleet faces is the first step toward building a business case for a telematics system implementation.

Approved as an alternative fuel under the Clean Air Act of 1990, propane autogas is certainly not new to the transportation industry. For several decades, many American fleets have used the fuel to reduce emissions and operating costs. But as the U.S Environmental Protection Agency tightens standards and regulations – a trend that is not likely to change in the foreseeable future – fleets across the country are ramping up their efforts to find more reliable, cleaner and more affordable fuel alternatives. And for utility fleets in particular, propane autogas is proving to be a viable option.

Vehicle Options
A growing number of OEMs now offer propane autogas vehicles that provide horsepower, torque and towing capacity comparable to gasoline and diesel versions of the same models. Most recently, medium-duty product offerings such as the ROUSH CleanTech Ford F-650 and Freightliner Custom Chassis Corp. S2G have entered the marketplace. Certified aftermarket propane autogas fuel systems from Blossman Services Inc. and ICOM North America have also emerged, providing utility fleet professionals with options that are ideal for service, bucket and crane trucks.

An initiative to increase utility fleets’ use of plug-in hybrid electric pickup trucks (see “Utilities Push Toward Fleet Electrification”) runs up against the reality that there are few vehicle options available to interested fleets.

But as growth in the electric power industry slows, electrifying the transportation sector “is a huge, albeit long-term opportunity for load growth,” the Edison Electric Institute stated in a June 2014 report, “Transportation Electrification: Utility Fleets Leading the Charge."

Electric utilities, EEI suggests, are missing an opportunity to help themselves by not expanding their use of plug-in electric vehicles. Only about 1.7 percent of the vehicles purchased by electric utilities in the last five years were equipped with plug-in technology, EEI noted, using data from Utilimarc, a consulting firm based in Minneapolis.

As utility fleets continue to search for cleaner-burning vehicles that operate more efficiently and use lower-cost fuel, the business case for natural gas vehicles (NGVs) is becoming clearer thanks to advancements in vehicle technologies and evolving infrastructure.

And yet, the recent decrease in oil prices – which is being driven, in particular, by a slowing global economy and increased supplies of shale gas in the U.S. – has left some people wondering about the future of NGVs. Do they still offer an economically viable solution for utility fleets? How will the decrease in oil prices impact initiatives to switch to clean-energy vehicles?

“Despite the current low cost of oil, natural gas still enjoys substantial cost savings compared to gasoline and diesel,” said Matthew Godlewski, president of NGVAmerica (www.ngvamerica.org), an organization dedicated to the development of a sustainable market for vehicles powered by natural gas or biomethane. “Utility fleets that have already begun to make the switch to natural gas and have seen its economic and other benefits firsthand are continuing to stay the course.”

In an effort to reduce fuel costs, extend replacement cycles and lower greenhouse gas emissions, an increasing number of utility fleets now operate electric vehicles (EVs). In fact, in November 2014, the White House and Edison Electric Institute announced that more than 70 U.S. electric utility companies have plans to devote at least 5 percent of their fleet acquisition budgets to buying plug-in EVs and related technology. Their investments will total approximately $50 million each year.

With fewer moving parts and less reliance on oil to lubricate and help cool the engine parts that do move, EVs represent a sound investment, over time, for many utility fleets. In addition to lower fuel costs and fewer emissions, others benefits of operating EVs include reduced noise levels, exportable power and lower total cost of ownership.

“While you pay more for a plug-in, the overall cost of ownership is significantly lower,” said David Meisel, senior director of transportation and aviation services at Pacific Gas and Electric (PG&E), explaining that payback for the company’s fleet usually ranges from two to seven years. “For our bucket trucks, we’re looking at paybacks in 24 to 30 months. Some of our light-duty applications pay back in five years or less. And some of our pickup trucks see payback in seven years.”

Pop quiz: Which uses more fuel and produces more emissions – letting a passenger car idle for 15 seconds or turning off a car and restarting it after 15 seconds?

If you answered that restarting the car uses more fuel, you would not be alone. Most people believe that starting is the less efficient option. But that’s not the case, according to research conducted by Argonne National Laboratory. Results of their experiment revealed that just 10 seconds of passenger car idling time actually uses more fuel than stopping and restarting the engine.

Founded in 1946, Omaha Public Power District is a publicly owned, business-managed electric utility governed by an elected board of directors and headquartered in Omaha, Neb. With a fleet operations staff of more than 50, OPPD services 5,000 square miles, covering 13 counties in southeastern Nebraska and serving 352,000 customers. In fact, OPPD is the 12th-largest public power utility in the United States in number of customers served. OPPD maintains multiple facilities, including three full-service garages in the metropolitan Omaha area, one full-service garage in south rural Omaha and a light-duty garage in downtown Omaha.
