| 2025 | $108/kWh | −8% | Actual (BNEF) |
| 2026 | ~$105/kWh | −3% | Forecast (BNEF) |
| 2030 | ~$69/kWh | — | Projection (BNEF) |

The implied CAGR, derived: from $108 (2025) to $69 (2030), the implied constant decline is (69 ÷ 108)^(1/5) − 1 ≈ −8.6% per year; from the $105 forecast for 2026, the 2026–2030 leg implies (69 ÷ 105)^(1/4) − 1 ≈ −10.0% per year. Either way the 2030 projection implies a sustained high-single-digit annual decline — far gentler than the 2010s collapse from $1,160/kWh.
The deceleration, quantified: 2025 fell 8%, 2026 is guided for 3% — the forecast's own numbers show the curve flattening in real time, which is what a maturing cost structure looks like.
The 2025 drop ran on oversupply — manufacturing capacity built ahead of demand, mostly in China (see the price cycle). The remaining decline is a different engine: chemistry shifts (LFP taking share from NMC), materials at half their 2022 levels (see the materials index), and scale — the same levers, but each with less left to give.
| Segment | 2025 price | Why it differs |
|---|---|---|
| EV packs | ~$108/kWh average | Automotive-grade cells, pack integration |
| Storage packs | ~$70/kWh | LFP-dominant, simpler integration, utility-scale volume |
The storage lead is the same two-speed shape as the storage market itself — LFP and scale pull storage prices down faster than automotive quality requirements allow.
BNEF's own caveat belongs in the record: geopolitics and policy changes add uncertainty to both EV adoption and pricing. The forecast's levers — oversupply persistence, policy support, materials markets — each carry a sign error risk. Treat the projection as the industry's centre of gravity, not a schedule: the direction is well-anchored, the timing is not.
My read: The forecast's most honest line is its slope — the 8% then 3% sequence says the battery industry is exiting its cost-collapse era and entering a slow-grind era, and every buyer should reprice their assumptions accordingly: future savings will be incremental, not revolutionary.
Why: The 2010s taught the market to expect miracles; the 2026 numbers teach it to expect percentages. Procurement plans, bankability models and fleet economics built on the old slope will overpromise; built on the new slope, they land. The forecast's value is not the 2030 number — it is the slope.
