The battery cost disconnect
For years, the battery energy storage (BESS) story has followed a familiar script: costs fall, deployment accelerates, economics improve. Even when cell costs rose and system prices briefly flattened during the 2021-22 lithium price spike, the narrative largely held. Paola Perez Peña, senior principal analyst at S&P Global Energy, examines why the latest jump in lithium prices has only had limited impacts on overall BESS costs so far.
