The 3-Layer stack that determines profitability of Battery Storage Systems

By interacting with many international companies that already have activities across different energy markets, I have gained extensive insight from hardware to software for batteries. Mass battery deployment in Spain begins in 2026-2027. If you have a large scale installation or you are considering them for your industry, the following information is useful to you. 

The 3-Layer stack that determines profitability:
⚡Algorithmic Trading Layer 
Analyzes price signals across day-ahead, intraday and balancing markets. Generates trading strategies and dispatch signals. This layer sees the profit opportunity, but it's useless if it can't communicate decisions downstream fast enough.

🔄 EMS (Energy Management System) 
Receives trading signals from above and translates them into physical dispatch commands. Manages constraints: current State of Charge, temperature limits, grid connection capacity, solar generation (if hybrid).

🔋  BMS (Battery Management System) 
Controls the physical reality, cell voltages, temperatures, charge/discharge rates. Feeds operational limits back up to the EMS. 

System Integration, the three layers operate as a bidirectional control loop:
Market price signal → Algorithm generates strategy → EMS executes dispatch → BMS validates against constraints → Operational limits feed back → Algorithm adjusts strategy
