Tesla team | 25.03.2025Benefits and economic returns of implementing battery storage
How battery storage cuts energy costs, covers peaks and gives businesses a return on investment in roughly five years.
At a time of rising energy prices, unstable supply and a strained distribution grid, battery storage is one of the most effective solutions for businesses that want to:
- take control of their consumption,
- reduce energy costs,
- increase operational stability,
- and support sustainability.
TESLA ENERGY GROUP offers business customers modular battery energy storage systems of its own manufacture, tailored to their specific needs – from small businesses to large industrial operations.
Cost optimisation through consumption management
One of the biggest advantages of battery storage is the ability to optimise electricity purchasing. Using peak shaving, the systems cover short-term consumption peaks – which would otherwise drive up electricity bills significantly.
Benefits for businesses:
- lower reserved capacity charges,
- buying energy during low-tariff periods,
- higher energy efficiency.
Model scenario for illustration and explanation:
Model company:
- Annual consumption: 1,200 MWh
- Electricity price: €150/MWh
- Costs without storage: €180,000/year
- Installed storage: 500 kW / 1,000 kWh
Savings after BESS installation:
- Energy savings: 20% (€36,000 per year)
- Reduced capacity charges: €10,000 per year
- Total: €46,000 saved per year
- Investment: approx. €230,000
Payback: approximately 5 years
