The EV Slowdown Could Supercharge Building Energy Storage

Battery makers are being forced to pivot. With electric vehicle sales plateauing after years of explosive growth, companies that built their fortunes on powering cars are now looking to power buildings instead. The global slowdown in EV demand has left manufacturers with excess production capacity and falling margins. That’s leading many to redirect their focus toward stationary energy storage including batteries designed to help stabilize power grids, manage peak loads, and provide backup power for homes and commercial buildings. This pivot isn’t just about market diversification, it’s about survival. And in the process, it could reshape how buildings manage energy.

For years, battery storage in buildings has been more promise than practice. The technology was available, but the economics rarely penciled. Between high upfront costs, regulatory hurdles, and uncertain payback timelines, most property owners viewed battery systems as futuristic luxuries rather than essential infrastructure. Now, that calculus may be changing. Battery makers are now moving aggressively into grid storage to offset weak EV demand. That shift could accelerate cost declines that make battery installations feasible for the broader commercial market...
