On-Grid Energy Storage: Energy Optimization in Grid-Connected Mode
- October 7, 2025
On-grid energy storage systems (ESS) operate while connected to the public electricity grid. They enable businesses, industries, and utilities to store energy during low-cost, off-peak hours and release it during periods of high demand or high electricity prices.
Unlike off-grid systems that rely entirely on renewable energy sources or backup generators, on-grid systems work synergistically with the grid to achieve economic optimization, improve grid stability, and maximize renewable energy utilization.
FFD POWER’s on-grid energy storage solutions are designed to make every kilowatt-hour count—turning energy management into an intelligent, automated process that reduces costs, enhances efficiency, and supports sustainable energy transitions.
Key Functions of On-Grid Energy Storage Systems
1. Peak Shaving and Valley Filling
Electricity prices fluctuate throughout the day. On-grid ESS can charge during valley periods when energy is cheap and discharge during peak periods when demand and prices rise.
This process—known as peak shaving—reduces electricity costs and relieves strain on the grid.
Example:
FFD POWER’s Galaxy 233L-AIO-2H systems are deployed in factories to charge during nighttime off-peak hours and discharge during peak hours, effectively reducing operational electricity bills and improving power quality.
2. Maximizing Solar Self-Consumption
In commercial and industrial solar projects, not all generated solar power is consumed immediately. Excess solar energy is often exported to the grid at a lower feed-in tariff.
An on-grid ESS stores this surplus solar energy for later use, allowing facilities to maximize solar self-consumption and minimize grid dependency.
This directly translates to greater financial returns and more sustainable operations.
3. Providing Grid Services and Stabilization
On-grid energy storage also plays a critical role in supporting the grid by offering services such as:
Frequency regulation
Voltage support
Load balancing
Demand response
Through intelligent control, FFD POWER systems can automatically respond to grid signals, contributing to grid resilience while generating additional revenue for the user.
How FFD POWER Optimizes On-Grid Energy Storage
