On-Grid Industrial Energy Storage

The most efficient and cost-effective solutions for renewable energy storage, peak-power shaving, frequency regulation and even more applications

FREQCON IES On-Grid Applications

FREQCON IES On-Grid systems allow the storage of unstable electric energy during wind and photovoltaic power generation and supply this energy when it is needed. Our energy storage systems can work grid connected to smooth the power output of renewable power plants or as base load power supply to the public grid.

The systems can work as stable voltage source within island grid installations to integrate renewable energy sources and diesel generation without the danger of black-outs or brown-outs.

FREQCON IES can be used for peak power shaving to reduce energy costs for commercial applications. Energy costs for industrial consumers strongly depend on their peak power demand. Just use FREQCON IES to cut these high peak demands and pay less for your energy.

The system is also able to provide frequency stabilization of the public grid. To compensate fluctuations of power consumption and production in the grid, balancing power is needed. The system therefore provides balancing power as source and also as consumer. At the same time, the reactive power capability makes it useful for voltage control applications.

Other applications the system is used for:

Energy smoothing in order to benefit from energy price fluctuations.

Harmonic compensation to improve the grid voltage quality.

Backup power supply during grid blackouts.
