Battery costs have shaped the pace and scale of the energy transition. For years, falling cell prices underpinned bullish business cases, opened up new flexibility markets, and helped grid-scale storage move from niche to mainstream.

But what happens when those cost declines level off?In this episode of Transmission, Aaron Wade returns to unpack the state of battery pricing in 2025. With lithium prices stabilising and cell costs holding firm in the $40–50/kWh range, the era of dramatic year-on-year price drops appears to be over.

That shift is changing how developers plan, how integrators position themselves, and what buyers prioritise when building or procuring storage.

We dig into the structural factors behind the price plateau, explore the commercial and technical implications, and ask: if price is no longer the main lever - what is?

In this episode we explore

⚡ Why have cell prices stabilised around $40–50/kWh and what’s keeping them there?

⚡ Are the big cost drops over for battery manufacturing?

⚡ What matters more than price now when designing storage systems?

⚡ How integrators are adapting to a more stable, competitive market

⚡ Are buyers over-specifying solutions and adding avoidable cost?
