Battle of the BESS: Integrated vs. Modular Energy Storage Solutions

Utility-scale energy storage deployment has reached an inflection point where hardware flexibility can determine project success or failure. With the U.S. Energy Information Administration projecting a record 18.2 GW of utility-scale battery storage additions in 2025—nearly double the 10.3 GW installed in 2024—developers face unprecedented growth alongside supply chain uncertainties, evolving battery chemistries, and changing […]
Battle of the BESS: AC- vs. DC-Coupling

In the rapidly evolving battery energy storage system (BESS) market, one of the most critical architectural decisions developers face is how to integrate their battery systems: with an AC-coupled or DC-coupled configuration. Neither approach is inherently better; rather, the optimal choice depends on the specific goals of the project, site constraints, and revenue strategies. Over […]
