One battery. Five levers. Tailored to your company.

1

Peak shaving

Capacity charges
€60,000–88,000/year
typical savings

Short power peaks set your annual peak demand and, with it, a large share of your grid fees. The battery cuts precisely these moments.

Starting point

In manufacturing plants the load level is usually stable. But when, for example, large loads start up at the same time, shifts change or compressors start in parallel, short, sharp peaks occur, and it is precisely these few minutes that set the annual peak demand.

How it works

The battery detects upcoming peaks and discharges precisely at these moments. The power drawn from the grid falls, the load curve is smoothed and your annual peak demand is lowered permanently.

Example calculation
Annual peak today3.2 MW
Target after peak shaving2.8 MW (−400 kW)
Capacity charge€150–220/kW/year
→ 400 kW × €150–220/kW
= €60,000–88,000/year
2

Atypical grid usage

§ 19(2) StromNEV
€200,000–320,000/year
at €800k in grid fees

Electricity-intensive companies that relieve the grid during peak load periods can apply for significantly lower individual grid fees.

Starting point

Grid operators define predictable peak load hours. Under the German Electricity Network Charges Ordinance (StromNEV), companies that demonstrably draw less power in these windows can apply for individual grid fees and pay significantly less.

How it works

The battery discharges automatically in the defined windows and pushes grid import below the critical threshold. Production continues unchanged.

Example calculation
Current grid fees€800,000/year
Typical reduction25–40%
→ €200,000–320,000/year in savings
3

Self-consumption optimisation

PV & CHP
€96,000/year
at 4 GWh solar output

Surplus self-generated power from solar PV or CHP is stored and used precisely when grid power is most expensive.

Starting point

Operators of solar PV or CHP (combined heat and power) plants face a timing mismatch between generation and consumption, so valuable self-generated power is fed into the grid on unfavourable terms.

How it works

The battery charges when surplus self-generated power could only be fed in at a low tariff, and discharges when grid power becomes expensive. Conflicts with peak shaving and atypical grid usage are avoided automatically.

Example calculation
On-site generation4 GWh/year
Self-consumption today → with battery50% → 70%
Additional volume800,000 kWh
Price gap (import vs. feed-in)€0.12/kWh
→ 800,000 kWh × €0.12/kWh
= €96,000/year

Dynamic tariffs

Dynamic prices
€43,800–65,700/year
at 1.5 MWh/day shifted

The battery charges when wholesale prices are low and discharges in expensive hours, automatically matched to your tariff.

Starting point

Many industrial companies buy part of their power on the spot, day-ahead or intraday market and are therefore directly exposed to market price fluctuations. As a result, prices differ markedly between cheap and expensive hours.

How it works

The battery charges when wholesale prices are low and discharges in expensive hours to reduce grid import. The FION software coordinates the tariff structure, forecasts and the other use cases.

Example calculation
Low/high price spread€0.08–0.12/kWh
Daily shifted volume1.5 MWh/day
Annual volume547,500 kWh
→ 547,500 kWh × €0.08–0.12/kWh
= €43,800–65,700/year

Arbitrage

Market revenue
Varies by project
on top of the classic use cases

Via direct marketers (specialist power traders), batteries can trade actively on spot, intraday and balancing markets for extra revenue.

Starting point

Arbitrage means actively monetising price differences on power exchanges: charging in cheap hours and selling when supply is scarce. This usually runs through a direct marketer.

How it works

Arbitrage complements the industrial use cases. Peak shaving, atypical grid usage and self-consumption are planned first. Then we check whether, and how, market revenue can usefully add to them.
