Container Battery Storage is a highly efficient solution for energy management and renewable energy integration. For European businesses and utilities, understanding the initial investment is crucial to evaluate feasibility and achieve long-term energy savings. This article provides a data-driven analysis to help you calculate costs and assess your project’s viability.
Key Cost Summary
- A 1MWh system: Costs between €695,000 and €850,000.
- Larger systems, like 5MWh, cost €3.5 million to €4 million, benefiting from economies of scale.
- Calculating initial costs involves assessing energy capacity, power requirements, and site-specific conditions.
How to Calculate Your Initial Costs
Assess Your Energy Needs
Start by determining the key parameters for your project:
- Energy Capacity (kWh): How much energy you need to store for your operations.
- Power Output (kW): The peak energy demand during high-use periods.
- Discharge Duration: The time your system needs to supply power without recharging.
Example:
- A factory with a peak load of 2MW and a requirement for 3 hours of backup energy would need:
Energy Capacity = 2MW × 3 hours = 6MWh.
Understand Key Cost Components
- Battery Modules
- Cost: €157–€190 per kWh (IRENA).
- Example: For a 6MWh system, battery costs range from €942,000 to €1.14 million.
- Power Conversion Systems (PCS)
- Cost: €0.05–€0.06 per watt.
- Example: For a 2MW PCS, costs range from €100,000 to €120,000.
- Containerization and Thermal Management
- Cost: €330–€400 per kWh (Energy-Storage.news).
- Example: For a 6MWh system, containerization adds €1.98 million to €2.4 million.
- Balance of System (BoS)
- Includes switchgear, cabling, and monitoring systems.
- Cost: ~20% of the system cost. For a 6MWh system, BoS costs range from €600,000 to €800,000.
- Installation and Commissioning
- Covers site preparation, labor, and commissioning.
- Cost: ~10% of total project cost. For a 6MWh system, this is approximately €400,000 to €500,000.
Total Cost Estimation
For a 6MWh System:
| Component | Cost (€) |
|---|---|
| Battery Modules | 942,000–1,140,000 |
| Power Conversion System | 100,000–120,000 |
| Containerization | 1,980,000–2,400,000 |
| Balance of System | 600,000–800,000 |
| Installation | 400,000–500,000 |
| Total | €4.02 million–€4.96 million |
How to Evaluate Your Project Feasibility
Determine ROI
Estimate your revenue streams and operational savings:
- Energy Arbitrage:
Buying electricity at €0.10/kWh off-peak and selling at €0.40/kWh during peak demand.- For a 6MWh system, daily arbitrage revenue: 6MWh × €0.30 = €1,800/day.
- Annual revenue: €657,000 (assuming 365 days of operation).
- Grid Services:
Providing ancillary services like frequency regulation can add €30,000–€50,000 annually per MWh. - Demand Charge Reduction:
Reducing peak electricity usage can save €50,000–€100,000 annually for a mid-sized factory.
Use Regional Incentives
- Germany: Up to 30% subsidy for energy storage under the Renewable Energy Sources Act (EEG).
- France: Tax breaks for renewable energy projects.
- Check country-specific programs to reduce upfront costs.
