What is IES?
Industrial Energy Storage (IES) is a comprehensive system made from electric-vehicle batteries and developed for the storage of electricity.
The IES system gives a second life to batteries that are no longer suitable for use in vehicles, but still have high capacity for use as stationary energy storage units. Through this approach, we extend the life cycle of batteries, support circular economy, reduce waste and contribute to reducing environmental impact.
IES was designed in cooperation with the car manufacturer Škoda Auto.
- Storage of energy
from PV plants - Backup energy
source - Optimisation of maximum
electric power in 15 minutes - Reduction of
reserve input power - Compensation
for grid quality - Secondary use
of batteries - Cost
savings
IES battery storage units are ideal for:
- Storing surplus energy from photovoltaics
- Operational energy backup
- Optimisation of maximum electric power in 15 minutes
- Reduction of reserved capacity
- Island operation
- Black-start support
Benefity
- Participation in power-balancing
and energy-trading services up to CZK 1,900,000/year max. 3 cycles per day / max. 650 cycles per year - Reduction of reserved
capacity up to CZK 560,000/year HV connection, reduction of reserved capacity by up to 210 kW - Lower costs for fast-charging
of electric vehicles (in combination with PV plants) by more than 60% in comparison with standard public charging stations - Reduction of electricity costs (in combination with PV plants) up to 109,500 kWh/year
- Protection against
unexpected power outages Storage system is equipped with
island-operation functionality
IES is offered in three power ranges while maintaining compact dimensions
