Peak-Valley Arbitrage
For Industry electricity saving
Maximize Factory Savings with Peak and Valley Energy Arbitrage
Reducing Energy Costs with Arbitrage
In today’s dynamic energy market, managing costs is critical for factories and industrial facilities.
What is Energy Arbitrage?
Energy arbitrage allows you to take advantage of price differences between peak and valley periods.
How It Works
By charging batteries during low-cost valley periods and discharging them during high-cost peak periods, factories can reduce overall energy expenses. This strategy also ensures a steady and reliable power supply.
FFD POWER Peak-Valley Solution
Distributed AC coupling BESS
FFD Power Cabinet BESS
FFD Power’s Cabinet BESS offers a nominal capacity of 233 kWh with 100 kW charging and discharging power.
Scalable Solution
This solution is scalable from 233 kWh up to 7 MWh, making it ideal for small to medium-sized businesses and industrial users using peak-valley arbitrage strategies.
Independent Operation
Each battery cluster connects to an independent Power Converting System (PCS). This ensures that every cabinet operates autonomously. If one cabinet experiences a fault, the others continue to function smoothly, maintaining uninterrupted performance.
Concentrated DC coupling BESS
FFD Power Containerized BESS
FFD Power’s Containerized BESS offers a nominal capacity of 3.42 MWh. Charging and discharging power ranges from 1250 kW to 1725 kW.
Scalable Solution
This system is scalable from 3.42 MWh up to 102.6 MWh. It is ideal for medium to large-scale industrial users and grid operators implementing peak-valley arbitrage strategies.
Flexible and Efficient Design
The batteries are separate from the Power Converting System (PCS). Multiple systems can be connected in parallel to the grid for larger capacities. This design is compact, cost-effective, and helps maximize efficiency and savings.

7MWH Distributed BESS
Parallel Cabinet System
FFD Power’s system connects 30 cabinets in parallel on the AC side. Each cabinet has a Power Converting System (PCS) delivering up to 100 kW of continuous charging and discharging power.
Individual Battery and EMS
Each cabinet includes a 233 kWh LiFePo4 battery storage system and its own Energy Management System (EMS).
Centralized Control
A central EMS communicates with all cabinet EMS units and the meter at the connection point. It controls charging and discharging power as well as timing.
Safety and Grid Protection
Transformer capacity protection prevents overpower during battery charging. Additionally, a zero export function ensures that no energy is fed back into the grid during discharge.
24MWH Concentrated BESS
Parallel Containerized BESS System
FFD Power’s system connects 7 containerized BESS units in parallel on the AC side. Transformers convert the 690 Vac output from each 1250 kVA PCS to the rated connection point voltage.
Individual Container Components
Each containerized BESS includes:
A 3.42 MWh LiFePo4 battery
A 1250 kW Power Converting System (PCS)
An AC transformer
Its own Energy Management System (EMS)
Centralized Coordination
A central EMS communicates with all container EMS units and the meter at the connection point. It manages charging and discharging power as well as timing.
Safety and Grid Protection

Bulgaria Electricity Price Analysis
On Thursday, August 29, 2024, the electricity price in Bulgaria was lowest between 03:00 and 06:00, averaging 48 Euro/MWh. During this period, the system can charge the battery fully in 3 hours.
Peak Price Period
The highest electricity price occurred between 19:00 and 21:00, averaging 500 Euro/MWh. The battery can be fully discharged in 2 hours during this period.
Precise EMS Control
Our Energy Management System (EMS) allows precise control of charging and discharging. Power can be adjusted every 15 minutes, maximizing financial benefits.
In addition to pre-setting charging and discharging power and time, our system integrates essential features to ensure optimal performance and protection:
Transformer Capacity Protection:
This feature prevents the total power from exceeding the nominal capacity of your transformer. For example, if you have a 1 MW transformer with a load power of 300-600 kW and a 500 kW/1 MWh BESS, the system automatically adjusts the battery charging power based on the load. If the load is at 300 kW, the battery can charge at its full 500 kW, as the total power (800 kW) is within the transformer’s 1 MW capacity. If the load increases to 600 kW, the EMS automatically reduces the battery charging power to 400 kW, ensuring the total power remains within the 1 MW limit.Zero Export Function:
To prevent energy waste during battery discharge, our zero export function ensures that the battery discharges only the amount of power needed by the load, without sending excess energy back to the grid. This is crucial as the grid typically does not pay for energy returned, and maximum benefit is achieved when the load fully utilizes the energy from the battery.
15 Mins Action
A 15-minute setting provides more granular control, enabling the system to be more responsive to market conditions, manage loads more effectively, and maximize financial returns. In Europe, where trading prices change every 15 minutes, this capability is especially crucial for staying competitive and optimizing energy costs
Higher Flexibility and Precision:
With a 15-minute setting, the system can adjust charging and discharging power more frequently. This allows you to respond quickly to changes in electricity prices, load demands, or grid conditions, optimizing energy usage in smaller increments. In Europe, where trading prices are updated every 15 minutes, this precision is particularly valuable for capturing short-term market opportunities. In contrast, a 1-hour setting might miss these brief but significant price fluctuations.Maximized Cost Savings:
Electricity prices can vary significantly within an hour. A 15-minute setting enables the system to capitalize on these fluctuations, charging during brief periods of low prices and discharging during high-price intervals. In markets like Europe, where prices update every 15 minutes, this setting ensures you are always optimizing your costs in real-time, resulting in greater savings compared to a 1-hour setting.Better Load Management:
In facilities with variable loads, a 15-minute setting allows for more precise load balancing. The system can better align energy supply from the battery with actual demand, reducing the risk of overloading the transformer or underutilizing the battery’s capacity.Enhanced Grid Interaction:
With more frequent adjustments, the system can better synchronize with grid conditions, such as demand response signals or frequency regulation needs. This can lead to additional revenue streams if the system participates in grid support programs, which often operate on short time intervals.Increased System Efficiency:
The ability to fine-tune the system every 15 minutes ensures that the battery operates closer to its optimal state of charge and discharge, prolonging its lifespan and improving overall efficiency.
