Day-Ahead Market Arbitrage

Day-Ahead Market Arbitrage is a revenue-generating strategy in the electricity market that capitalizes on price volatility by buying low and selling high on a day-ahead basis. It leverages sophisticated algorithms for market analysis and price forecasting, enabling participants to lock in profitable spreads and maximize returns.

What Makes Day-Ahead Market Arbitrage Different?

Day-Ahead Market Arbitrage leverages electricity price volatility to optimize energy buying, selling, and storage strategies before real-time operations begin. Unlike fixed-tariff models or simple load shifting, this approach requires accurate forecasting, advanced bidding algorithms, and seamless system coordination to capitalize on dynamic market conditions. The challenge lies in anticipating price curves, managing constraints, and acting with precision—where our expertise delivers measurable results.

Case Presentation

String-Type PCS for Utility-Scale Deployment BESS for Day-ahead Arbitrage in Italy

BESS for Day-ahead Arbitrage in Italy grid-connected 2.5MW/5MWh deployment with string-type PCS and modular battery containers

FFD POWER deployed a 2.5 MW / 5 MWh grid-connected Battery Energy Storage System (BESS) near the Autodromo Enzo e Dino Ferrari to take advantage of day-ahead electricity price fluctuations in Italy. The system uses string-type PCS and modular battery containers, enabling flexible scaling and easy on-site maintenance.

Background and Challenges

  • Italy’s electricity market shows significant intra-day price differences, creating opportunities for batteries to buy at low prices and sell at high prices for arbitrage.

  • The project is part of a larger 40 MW / 80 MWh multi-site deployment plan, requiring standardized design for efficient implementation and operation.

  • The system must ensure accurate day-ahead dispatch, reliable state-of-charge (SOC) management, and compliance with local grid regulations.

FFD POWER Solution

  • Deployed a 2.5 MW / 5 MWh string-type PCS BESS with a modular architecture for enhanced reliability and simplified maintenance.

  • Integrated Energy Management System (EMS) enables automatic charge/discharge scheduling based on day-ahead electricity price forecasts—charging during low-price periods and discharging during high-price periods.

  • EMS manages SOC boundaries and power limits to ensure repeatable and safe daily operation.

  • String-based modular design allows independent operation of each subunit, improving system reliability and maintenance efficiency.

System Specifications

  • Project Scale: 2.5 MW / 5 MWh (single site), overall 40 MW / 80 MWh

  • Output Power: 2.5 MW

  • Storage Capacity: 5 MWh

  • Equipment: Galaxy 5015 String-Type Battery System + EMS

  • Architecture: Grid-connected string-type BESS for day-ahead arbitrage and grid optimization

Key Highlights

  • Modular string-type PCS and battery units

  • Accurate EMS execution of day-ahead price-based dispatch

  • SOC management ensures repeatable, reliable operation

  • Scalable design suitable for large-scale, multi-site deployment
