All audio, lighting, video and stage production on the main stage at this year’s Lollapalooza will be entirely powered by a hybrid battery system, the festival announced Monday (July 29).

According to organizers, that makes Lollapalooza the first major U.S. music festival to have a main stage run entirely on a hybrid battery system. Typically, diesel generators power the stages at large-scale events.

Lollapalooza’s hybrid-powered stage will deploy over 1.5 MWh of battery storage capacity. A representative for the festival tells Billboard that the batteries are reusable and will be charged using diesel generators that run on biodiesel fuel (typically made from renewable sources like vegetable oil, animal fat or recycled cooking grease and used as a cleaner-burning alternative to petroleum-based diesel fuel). That’s similar to systems that power hybrid vehicles.

The batteries, manufactured by Swedish industrial tools and equipment company Atlas Copco, will be deployed by CES Power, which provides temporary event power generation, power distribution, and HVAC for festivals, film and broadcast, major events, and industrial projects. The system is being deployed via a partnership between Live Nation’s sustainability initiative Green Nation, T-Mobile and CES Power.

“We have set a goal to build a more sustainable future for music festivals, which requires taking bold steps to find solutions that can reinvent how we operate and in turn, build industry trust in new technology so that major live events can see a path towards becoming more energy efficient,” Jake Perry, director of operations and sustainability at C3 Presents, which produces Lollapalooza, said in a statement.

“Solutions like the ones Lollapalooza are pioneering not only contribute toward our global Green Nation goal of cutting our emissions in half by 2030, but they provide local benefits as well through reduced noise and air pollution which creates a better experience overall for the artists, fans and crew,” added Lucy August-Perna, head of global sustainability at Live Nation. “We look forward to sharing the results and learnings from Lollapalooza with our network of over 200+ festivals around the world who are committed to raising the bar for more sustainable live events.”

Major events have historically been reticent to incorporate hybrid battery power due to concerns about its reliability, but such batteries are becoming more popular on the live scene as the technology advances. This past May, California’s Mill Valley Music Festival became the first U.S. festival to be powered by 100% renewable energy through the use of batteries.

This isn’t the first time Lollapalooza has experimented with green energy on its main stage. Last August, Billie Eilish‘s headlining set at the festival was partially run on a solar-powered battery system via an initiative with environmental nonprofit Reverb.

Lollapalooza 2024’s headliners include Meghan Thee Stallion, Hozier, SZA, Stray Kids, The Killers, Future and Metro Boomin, Blink 182, Melanie Martinez, and Skrillex.
