Simulations as the Basis for Selecting the Right Storage System

/in /by

Why Simulation?

The selection of a battery storage system has a decisive impact on the profitability, safety, and lifetime of a project. With detailed simulations of load profiles, electricity prices, and market models, we determine the optimal storage size and operating strategy.

This makes it possible to avoid revenue losses due to curtailment, take advantage of new market models, and transparently evaluate economic viability. The result: a well-founded basis for decision-making that provides security for investors and tailors the storage system precisely to your project.

Methodology

  • Load and generation profiles (PV/wind, consumption, grid constraints) are modeled at high temporal resolution (e.g. 15 min/5 min).
  • Dispatch optimization (self-consumption, arbitrage, balancing services, peak shaving, multi-use) with technical constraints (SOC limits, efficiencies, C-rate).
  • Degradation model (calendar & cycle) to forecast capacity losses, efficiency, and residual value.
  • Scenarios & sensitivities: prices, curtailments, CAPEX/OPEX, subsidy conditions, grid fees.

Input Data

  • Location and weather data, historical/forecast electricity prices, grid tariffs & demand charges.
  • Technical datasheets (BMS limits, DoD, round-trip efficiency, temperature range).
  • Project and financial parameters (CAPEX, OPEX, interest rate, lifetime, residual value, insurance).

Key Performance Indicators (KPIs)

  • NPV, IRR, payback period, cash flow profile.
  • Number of cycles, full cycle equivalents, expected lifetime and residual capacity.
  • Revenue contributions by market model (self-consumption, arbitrage, balancing services, etc.).
  • Avoided curtailment losses and peak shaving savings.

Result & Benefits

  • Tailored system sizing (kWh/kW) and optimized operating strategy.
  • Transparent investment decision with reliable financial metrics.
  • Techno-economic alignment: return targets vs. lifetime/degradation.
  • Bank & investor ready: documentation for financing, tenders, and insurers.
