01 — The Challenge

Rising Energy Costs Without Control

The facility faced increasing electricity expenses driven by peak tariffs and demand charges, with no flexibility to optimize when energy was purchased.

⚡

High Peak Tariffs

Peak electricity price: ~€0.38–0.45/kWh

🌙

Low Off-Peak Price

Off-peak electricity price: ~€0.12/kWh

📊

High Demand Charges

Monthly demand charges: ~€8,000

🔋

No Load Flexibility

No ability to shift when energy was purchased

02 — Project Overview

System Configuration & Key Financial Inputs

System Configuration

  • 300kW / 645kWh C&I Energy Storage System
  • LFP battery chemistry (6,000+ cycles)
  • Grid-tied hybrid inverter
  • Cloud-based EMS for dispatch optimization

Key Financial Inputs

  • Peak price: €0.38/kWh
  • Off-peak price: €0.12/kWh
  • Spread: €0.26/kWh
  • 1 cycle/day · 300 operating days/year
03 — How the ROI Is Calculated

Simple, Transparent Economics

Annual savings are driven by daily energy arbitrage — the systematic capture of the peak/off-peak price spread, every day, automatically.

ROI Calculation
645 kWh × 1 cycle/day × €0.26 spread × 300 days = ≈ €50,000/year
Assumes 90–95% round-trip efficiency and real dispatch losses. Based on systematic daily capture of the off-peak/peak spread under Italy TUT PUN Zone 6 tariff structure, 2025.
📊 Actual project result: €47,700/year — slightly lower than theoretical due to efficiency losses (95% RTE) and first-year EMS calibration.

EMoreShare configured a system aligned with the facility's load profile and tariff structure:

🔋

Battery System

645kWh LFP battery optimized for daily cycling

  • 6,000+ cycles
  • 10-year warranty
  • 80% depth of discharge
⚡

Inverter

300kW bidirectional inverter

  • Supports peak shaving
  • Grid interaction capability
  • Backup function
📊

EMS

Cloud-based energy management system

  • Time-of-use optimization
  • Day-ahead tariff forecasting
  • 24/7 remote monitoring
05 — Risk & Sensitivity

What Could Impact ROI

To ensure realistic expectations, we model against three key variables:

📉 Tariff Spread Compression

If spread narrows significantly: IRR drops to 12–14%. Underwritten with −30% sensitivity.

🔋 Utilization Below 0.7 Cycles/Day

If load profile changes and cycles fall: IRR extends beyond 5 years. EMS allows dispatch flexibility to adapt.

⚡ Incorrect System Sizing

Oversizing increases CAPEX without proportional return: ROI efficiency drops significantly. Correct sizing is validated against load profile.

Bottom line: Even under conservative scenarios, storage remains financially viable in high-tariff markets. The arbitrage mechanism does not depend on government subsidies.
