# Battery storage costs crossing below 100 dollars per kWh make renewables dispatchable and fundamentally change grid economics by enabling solar and wind to compete with firm baseload power

Lithium-ion battery pack prices have fallen from over $1,200/kWh in 2010 to approximately $139/kWh globally in 2023 (BloombergNEF), following a learning rate of ~18-20% per doubling of cumulative production. Chinese LFP (lithium iron phosphate) packs have already breached $100/kWh, and BloombergNEF projects the global average crossing this threshold by 2025-2026.

The $100/kWh mark is not arbitrary — it is the threshold at which 4-hour battery storage paired with solar becomes cost-competitive with natural gas peaker plants for daily cycling. Below this price, "solar + storage" becomes a dispatchable resource that can be contracted like firm power, fundamentally changing the competitive landscape. Utilities no longer need to choose between cheap-but-intermittent renewables and expensive-but-firm fossil generation.

The implications cascade: grid-scale storage enables higher renewable penetration without curtailment, residential storage enables energy independence, and EV batteries create a distributed storage network that can provide grid services. Battery manufacturing follows the same learning curve dynamics as solar — Wright's Law applies, and scale begets cost reduction.

## Challenges

The $100/kWh threshold enables daily cycling (4-8 hours) but does not solve seasonal storage. Winter in northern latitudes requires weeks of stored energy, and lithium-ion economics don't support discharge durations beyond ~8 hours. Long-duration storage candidates (iron-air, flow batteries, compressed air, hydrogen) remain 3-10x more expensive than lithium-ion and lack comparable manufacturing scale. Lithium, cobalt, and nickel supply chains face concentration risk (DRC for cobalt, Chile/Australia for lithium), though LFP chemistry reduces critical mineral dependence. Battery degradation over 10-20 year project lifetimes introduces uncertainty in long-term LCOE projections.

Relevant Notes:
- [[solar photovoltaic costs have fallen 99 percent over four decades making unsubsidized solar the cheapest new electricity source in history and the decline is not slowing]] — storage makes solar dispatchable, completing the value proposition
- [[AI datacenter power demand creates a 5-10 year infrastructure lag because grid construction and interconnection cannot match the pace of chip design cycles]] — battery storage can provide bridge capacity while grid infrastructure catches up
- [[the atoms-to-bits spectrum positions industries between defensible-but-linear and scalable-but-commoditizable with the sweet spot where physical data generation feeds software that scales independently]] — battery manufacturing is atoms-side with software-managed dispatch optimization
