The choice is influenced by the energy market where the BESS operates, as well as market conditions, financial goals, and the investor's risk appetite. Regardless of the model, BESS systems offer the flexibility to provide multiple applications simultaneously, enabling operators to stack revenues from diverse sources and align revenue strategies with evolving market opportunities. Most systems built in 2024 used some combination of contract and merchant-driven revenue.
