Why Joule Case?


Joule Case provides innovation in a largely stagnant battery market, replacing noxious generators with clean, safe, cost-efficient renewable power in the fast-growing event-power industry with music festival partners like Burning Man and Electric Daisy Carnival (EDC).



Portable and backup power is noisy, toxic, expensive—and poses a serious public health safety issue. But even as we transition towards a greener grid, we’re still heavily dependent on lithium ion battery technology for energy storage—half a century after it was first developed. Time for some serious innovation—and Joule Case is up to the task.




Finally—a major shift in the battery scene. Prices have dropped 87% in a decade, and big initiatives plus an influx of capital is pushing the sector forward—fast. Now, Joule Case isn’t here to reinvent the wheel, but this innovative startup has found an ingenious way to help batteries play nicely together in a stackable format.

Onto their first mission: making music festivals greener.




The future of portable energy is here and it’s simple, silent, safe, and clean. Joule Case’s grid-scale batteries are intuitive, user-friendly, and stackable: if you need more power, all you need to do is stack. No generators, no noise, no smell, no CO2. Just efficient energy wherever and whenever you need it.




Power is one of the largest production costs for a music festival, and it can account for over 70% of its core carbon footprint. Recent lawsuits against Coachella and other concerts have revealed dangerously high levels of toxins in the air—from diesel generators—at these events. And with fuel costs rapidly rising and the energy market forecast as increasingly volatile, something’s gotta give.




The music festival sector has a unique opportunity to contribute to CO2 reduction, showcase new innovation, and engage audiences. Joule Case is partnering up with LIVE Nation, Insomniac Events, and festivals like EDC and Burning Man to transition from loud, harmful generators to renewable, stackable energy.

“The potential for Joule Case in music festivals is massive.”

– Rutger Jansen (Director of Camp EDC)


With events coming back bigger than ever, we believe Joule Case is poised for incredible growth. Starting with Insomniac Events, organizer of Electric Daisy Carnival, Joule Case is on a mission to replace all the dirty diesel generators at concerts and outdoor events with clean, safe, renewable power.




The $30B lithium ion battery market is predicted to spike four-fold over the coming decade. Event power itself is a fast-growing market at 25% CAGR that sits directly in sight for Joule Case technology.



Event-powering generators are the subject of recent lawsuits against events including Coachella under California’s Prop 65. Seven-time Grammy-winning band Coldplay recently announced a return to touring after pausing in protest against venue diesel emissions. This announcement also unveiled plans for their shows to be powered exclusively by a rechargeable battery system.

Toxins from diesel generators are known to contribute to cancer and premature death, and combined with other compounds in sunlight they form ozone, a potent trigger for asthma attacks and other health issues. What started as a purely environmental issue has quickly escalated into a public health and safety issue, and the verdict is in: event-powering generators need to go.

Additionally, with California signing into law Assembly Bill 1346, which will effectively ban small gas-powered generators, the widespread transition to clean battery alternatives has begun.
