Suburban Propane's Green Gamble: Powering the EV Future Off the Grid

SAN DIEGO, CA – June 23, 2026 – Amid the roar of engines and the high-octane energy of a NASCAR race weekend, an unusual sight unfolded at Naval Base Coronado. Tucked away from the track were sleek electric vehicle (EV) chargers, humming as they powered up cars. The source of their electricity, however, wasn't the local grid. It was propane. More specifically, it was renewable propane, supplied by a nearly century-old company, Suburban Propane.

At first glance, the partnership seems counterintuitive: a legacy fossil fuel distributor powering the very vehicles designed to replace gasoline and diesel. But peeling back the layers of this demonstration, a collaboration between Suburban Propane, technology firm ABB, charger manufacturer Kempower, and NASCAR, reveals a fascinating story. It’s a story about pragmatism in the energy transition, the hidden challenges of electrification, and a traditional company’s strategic maneuver to secure its place in a lower-carbon future.

This wasn't just a marketing stunt; it was a real-world test of a solution to one of the biggest hurdles facing widespread EV adoption: the grid. As more drivers go electric, our existing infrastructure is groaning under the strain. For large-scale temporary events like a NASCAR race, or in remote areas and during emergency situations, plugging in a fleet of EVs simply isn’t an option. This project aimed to prove there’s another way.

A Bridge to an Electric Future

The technical setup in San Diego was a clever, multi-step process. Suburban Propane provided renewable propane to fuel on-site generators. These generators didn’t power the EV chargers directly; instead, they charged large battery storage systems. From there, ABB’s power management equipment directed the electricity to Kempower’s mobile DC fast chargers, providing on-demand power for EVs. This system creates a portable, self-contained microgrid, capable of being deployed anywhere.

"This collaboration demonstrated how renewable propane can complement emerging technologies by providing reliable energy where and when it's needed," said Nandini Sankara, a spokesperson for Suburban Propane. The sentiment was echoed by partners who see the need for a diverse energy portfolio.

"The country's massive energy expansion will require a diversity of generation sources to meet growing demand," noted Chris Shigas, ABB's Vice President of Strategic Partnerships, framing the technology as a cleaner alternative to the traditional diesel generators often used for temporary power.

For an organization like NASCAR, which operates massive, logistically complex events, the appeal is obvious. "This partnership showcases how practical, lower-carbon energy solutions can perform in real-world, high-demand environments," said Amy Lupo, President of NASCAR San Diego. It offers a path to support sustainability goals without compromising operational needs, especially in locations like a naval base where permanent infrastructure changes may be difficult.

Digging Into the Data: What Does 'Renewable' Mean?

As a market analyst, I’m trained to be skeptical of buzzwords like 'green' and 'renewable.' The real story is always in the numbers. The company’s press release claims renewable propane has a "significantly lower lifecycle carbon intensity." My research confirms this claim is not just marketing fluff.

Renewable propane is chemically identical to the conventional propane used in backyard grills, but its origin story is entirely different. It’s produced from renewable feedstocks like used cooking oil, animal fats, and plant oils. This 'drop-in' nature is a huge advantage—it can be used in existing equipment and supply chains without any costly modifications.

The critical metric here is Carbon Intensity (CI), which measures greenhouse gas emissions across a fuel's entire lifecycle, from production to combustion. The data is striking:

• Conventional Propane: Has a CI score of around 80 gCO2e/MJ (grams of CO2 equivalent per megajoule).
• Diesel: Sits higher, at approximately 100 gCO2e/MJ.
• Average U.S. Electric Grid: Surprisingly, the electricity from our walls is often not as clean as we think. The U.S. grid average CI score is about 130 gCO2e/MJ, largely due to its continued reliance on coal and natural gas.
• Renewable Propane: Depending on the feedstock, its CI score can be as low as 20.5 gCO2e/MJ. That's nearly 75% lower than conventional propane and less than 16% of the carbon intensity of the average U.S. grid.

In this context, using renewable propane to generate off-grid electricity for EVs is not a step backward. In many cases, it’s a cleaner alternative to charging from a fossil-fuel-heavy grid, and it dramatically outperforms the diesel generators typically used for such events by reducing both carbon and harmful particulate matter.

A Strategic Pivot for a Legacy Company

This demonstration is more than a technical showcase; it's a window into the strategy of Suburban Propane Partners, L.P. (NYSE: SPH). As a publicly traded master limited partnership founded in 1928, the company has built its business on distributing propane. In an era defined by decarbonization, standing still is not an option.

Through its "Go Green with Suburban Propane" pillar and the formation of Suburban Renewable Energy, LLC, the company is actively investing in a future beyond its traditional business. It has already directed over $300 million toward low-carbon ventures, including renewable natural gas and hydrogen, in addition to renewable propane. This NASCAR activation is the public face of that pivot, signaling to investors and customers that the company intends to be a participant, not a casualty, of the energy transition.

By positioning renewable propane as a complementary fuel—a solution for the hard-to-electrify gaps in our system—Suburban Propane carves out a vital niche. It’s not competing directly with grid-based EV charging in dense urban areas; it’s providing a solution where the grid falls short. This strategy allows the company to leverage its nearly 100 years of expertise in fuel logistics and distribution while adapting to a new energy paradigm.

The Question of Scale

An innovative demonstration is one thing; a scalable, economically viable solution is another. Can this model be replicated widely?

The primary enabler is renewable propane’s status as a 'drop-in' fuel, which eliminates the need for new, multi-billion-dollar infrastructure. The production side is also promising. Renewable propane is a co-product of renewable diesel and sustainable aviation fuel (SAF) manufacturing. As demand for those fuels skyrockets, the supply of renewable propane is set to increase dramatically alongside them. Current U.S. production capacity is over 4.5 million gallons annually and growing, with some industry forecasts suggesting it could meet half the world's propane demand by 2040.

Of course, challenges remain. Current production volumes are still a fraction of the total propane market, and the cost can be higher than its conventional counterpart. However, financial incentives like credits under the federal Renewable Fuel Standard and California's Low Carbon Fuel Standard are helping to close that gap, making it an economically attractive option for producers and, increasingly, for consumers.

The ultimate role for this technology likely isn't to power every EV on the road, but to serve as a critical tool for resilience and access. It’s a solution for fleet operators who need to charge vehicles in remote yards, for first responders who require power in disaster zones, and for bringing EV access to events and communities that the grid has yet to reach.
