Why your load profile decides your ROI

We size the battery based on your actual load profile, not rules of thumb.

Our promise

Your battery recommendation. Concrete and reliable.

We size your battery so that the calculated economics hold up in practice. You receive:

01

Battery sizing

1–2 concrete battery recommendations with power (kW) and capacity (kWh)

02

Economics

Expected payback period, annual savings potential, investment range

03

Use case overview

Side-by-side assessment of the main operating strategies and their savings impact

04

Sensi­tivity analysis

How robust the results are when electricity prices, load profiles or contracts change

Without load analysis

Every wrong assumption delays payback.

No two industrial sites are alike. Grid connection, voltage level, load curve, power contracts and on-site generation determine the economics. Blanket rules fall short.

Too small

Electricity costs barely fall. Capacity charges, grid fees and self-consumption stay almost unchanged, and the business case collapses.

Too large

Unnecessary investment with no added benefit. Excess capacity ties up capital without delivering further savings. In operation, the extra capacity is systematically underused.

First understand the load profile. Then size the battery.

Our process

From your raw data to a reliable recommendation.

We analyse your site in three clear, traceable steps, from the underlying data to the battery recommendation.

  1. Step 1

    Data collection and quality check

    We import load profiles and tariff data, check them for completeness and plausibility, and clean up metering errors and outliers.

  2. Step 2

    Simulating battery and use case combinations

    Our software systematically simulates different battery sizes and operating strategies: peak shaving, solar self-consumption and more. The goal is not the theoretical optimum but the most cost-effective solution.

  3. Step 3

    Economic assessment

    For each option we calculate investment and operating costs, annual savings, the expected payback period and how sensitive the results are to changes in electricity prices or usage profiles. From these options we identify the solution that fits your strategy.

Data input

No assumptions. Only your data.

For reliable sizing, our software systematically combines four site-specific data sources.

FION software: energy flow overview with load profile, grid import, grid feed-in and state of charge
Input 1: Load profiles (RLM)
  • 15-minute data covering at least 12 months
  • Actual annual peak demand and load peaks
  • Daily, weekly and seasonal patterns
  • Solar PV or CHP generation
Input 2: Electricity prices & grid fees
  • Current and planned power contracts
  • Energy charges, capacity charges and grid fees
  • Peak load windows and atypical grid usage (reduced grid fees under § 19(2) of the German Electricity Network Charges Ordinance, StromNEV)
Input 3: Grid connection data
  • Import and export at the grid connection point
  • Voltage level and technical constraints
Input 4: Future outlook
  • Changes to production or shift patterns
  • New equipment or electrification
  • Site strategy (growth or consolidation)
