Supercool Cleaning the Grid: Wärtsilä Tackles the Toughest Battery Storage Projects on Earth
Grid battery storage has gone from niche to necessary. Fast. Projects that were once 300 megawatt-hours are now hitting 9 gigawatt-hours. And companies like Wärtsilä are leading the charge, taking on the hardest, highest-stakes deployments around the world.
In this episode, Dave Hebert, VP of Global Sales & Business Strategy for Wärtsilä's Energy Storage division, takes us inside the systems powering the clean energy transition. Wärtsilä has deployed over 17 gigawatt-hours of storage—enough to power millions of homes for hours at a time—across more than 130 projects worldwide. Many of these are first-of-a-kind systems built in remote deserts, on islands, and in densely populated urban neighborhoods, where batteries now operate alongside people, not just power lines.
Dave shares what it takes to deliver at this level: fire safety, noise control, seismic readiness, cybersecurity, and software managing millions of real-time data points across every cell.
Battery storage now sits at the heart of the energy transition. It’s how we make solar and wind reliable. How we stabilize grids shaped by AI, EVs, and electrified homes. Wärtsilä is building that future, where others won’t.
