Revenue Stacking at an Industrial Site — in Italy
Project Overview
BESS for Power Trading and FCR in Italy demonstrates how a 2.5MW/5MWh battery energy storage system can stack market dispatch with fast frequency services to improve project economics. Deployed at an industrial site, the system charges during low-price windows and discharges during high-price periods, while reserving capacity to deliver Frequency Containment Reserve (FCR) when the grid needs it. A revenue-stacking EMS coordinates dispatch setpoints, SOC reserve, and compliance logging to keep the asset available, responsive, and battery-safe.
Project Background
Across Europe, industrial facilities are increasingly exposed to volatile electricity prices and grid-balancing requirements. At the Florim site in Italy, the operator sought a flexible asset that could both monetize energy price spreads and participate in frequency services without compromising operational reliability. This created a need for tight real-time coordination between market-driven charge/discharge schedules and frequency-response obligations.
Project Challenge
- Dual-Objective Control: Execute power trading dispatch while maintaining continuous FCR availability and avoiding conflicting commands.
- SOC Reserve Management: Hold a protected SOC corridor for symmetric up/down response, and recover SOC after events without over-cycling.
- Settlement & Compliance: Provide time-synced metering, response verification, and event logs required for market settlement and performance auditing.
FFD POWER Solution
FFD POWER implemented a containerized, grid-connected BESS integrated with a market-ready EMS, enabling the site to operate the system as both a dispatchable energy asset and a fast frequency-response resource. The EMS orchestrates dispatch scheduling, SOC reserve enforcement, and frequency-response control, while recording high-resolution operational data for O&M and settlement.
System Specifications
- BESS POWER : 2.5 MW
- BESS capacity : 5 MWH
- Product used : Galaxy5015 String Type BESS
- Application : Power trading + FCR
- Architecture: EMS with dispatch scheduling + FCR controller (SOC reserve)
Operational Logic: Dispatch + FCR with SOC Reserve
The core innovation lies in how the EMS stacks market dispatch with frequency response while protecting SOC and battery life:
- Market Dispatch Scheduling: Charges in low-price windows and discharges in high-price periods, respecting power limits and SOC constraints.
- FCR Overlay Control: Superimposes droop-based frequency response on top of the dispatch baseline, with configurable deadband and ramp limits.
- SOC Reserve & Recovery: Enforces an SOC corridor to guarantee up/down response; after FCR events, automatically rebalances SOC to target without breaking dispatch commitments.
