Between the Terminals

U.S. energy developers are navigating recent policy changes, but the energy storage project pipeline continues to grow, and domestic equipment sourcing remains a key consideration for moving projects forward. In other parts of the world, energy storage is breaking record deployments, and the appetite for these systems only continues to increase.

TLDR · What matters most

Policy & Markets

Competitive TCO, detailed specs and strong local presence key for BESS supplier success in Germany, RWE says
