COMPILED NOTES

LCOS $78/MWh (4-hour BESS), LFP at $65/MWh, below gas peaker cost in 6+ markets, battery storage as #1 energy investment

Grid storage LCOS reaches $65-78/MWh — below gas peaker economics

Key Contributions

Levelized cost of storage (LCOS) for 4-hour battery energy storage systems (BESS) has fallen to $78/MWh
LFP chemistry achieves even lower LCOS at $65/MWh
Battery storage now cheaper than gas peaker plants in 6+ markets — a critical economic tipping point
Battery storage identified as the #1 energy investment category for 2026
Signals the end of gas peakers as the default grid flexibility solution

Results / Data

LCOS (4-hour BESS): $78/MWh
LCOS (LFP): $65/MWh
Markets where BESS undercuts gas peakers: 6+
Investment ranking: #1 energy investment for 2026
Implication: economic case for battery storage now self-sustaining without subsidies in key markets
