For many commercial and industrial users, electricity costs are not only driven by total energy consumption, but by how much power is used at peak moments. Short demand spikes can significantly increase monthly electricity bills. In Bulgaria, a factory faced exactly this challenge—making peak demand control a priority for cost reduction.
1. System: Single-cabinet energy storage system
2. Power / Capacity: 115 kW / 233 kWh
3. Application: Factory electricity consumption4. Use Case: Peak shaving, valley filling, and peak-valley arbitrage
The facility experienced recurring peak load periods during daily operations, resulting in:
1）Elevated demand charges
3）Limited flexibility in energy usage
The issue was not total consumption—but when energy was used.
To address this, Pytes deployed a Pi Station 230 system designed to actively manage energy usage:
1) Charge during off-peak hours when electricity prices are lower
3) Automatically respond to load changes in real time
No manual intervention. No operational disruption.
The system's pre-integrated, plug-and-play design enabled fast deployment with minimal impact on site operations.
With peak demand effectively controlled, the system delivers:
1) Reduced demand charge exposure
3) Improved overall energy cost management
Energy becomes manageable—not just consumable.
Dual fire protection system (aerosol + water) with integrated safety response
2. Stable in Any Environment
IP55 protection with liquid cooling for consistent performance
3. Financial Visibility
Real-time monitoring enables tracking of savings and system performance4. Grid-Ready
PCS certification ensures compliance with local utility requirements
This project demonstrates a key reality:
Peak shaving is not a theory—it is a proven, repeatable financial strategy.
With successful deployments across Europe—including Austria, Switzerland, and Romania—Pytes continues to validate its capabilities in commercial and industrial energy storage.
These real-world projects also provide a strong foundation for expanding high-voltage C&I solutions in the U.S. market, bringing proven experience to future deployments.
