How to Choose the Right Energy Storage System for Your Business
Key Data and Requirements for Selecting an Energy Storage System
Electrical parameters of the facility: The contracted and connection capacity are critical in defining the available limits for a plant. They also directly affect grid fees, as exceeding the contracted capacity may lead to penalties. These parameters determine the required inverter power and battery capacity.
Consumption profile: Annual energy usage, monthly seasonality, and hourly load profiles are essential for sizing the storage correctly. A facility working in one, two, or three shifts — or operating 24/7 — requires a different storage strategy. A detailed analysis allows optimization of charging and discharging cycles, peak shaving, and efficient use of renewable generation.
On-site renewable and generation sources: If the facility already has a PV installation, the storage system can capture excess production and discharge it during evening peaks or cloudy days. Additional energy sources such as wind turbines, cogeneration units, or backup generators can also be integrated with the storage system.
Installation and infrastructure conditions: Available space (container-based or indoor solutions), ventilation, cooling requirements, and readiness of switchgear and metering points must all be assessed. A single-line diagram is required to define connection points and boundaries of responsibility.
Business objectives and operation mode: The purpose of the investment determines the design:
Cost reduction: peak shaving, tariff optimization, and reduced energy purchase during expensive hours.
Energy security: backup supply and island mode operation during outages.
Maximizing self-consumption: using more of the energy generated on-site instead of selling excess to the grid at low rates.
Revenue generation: participation in demand response programs (DSR), capacity markets, frequency regulation, or energy arbitrage.
Future perspective: Expansion of production lines, increased demand, or new renewable installations may require scaling the system. Modern storage solutions are modular and can grow from several hundred kWh to multiple MWh as business needs evolve.
