Eliminating Peak Demand Charges with Integrated Storage
Client: Major Global Logistics Provider | Location: Southern California | Solution: Commercial Solar & Energy Storage
The Challenge
The client's massive distribution center in Southern California faced crippling peak demand charges from the local utility, primarily driven by high-power material handling equipment and HVAC systems operating during the late afternoon. The existing 2.5MW rooftop solar system was not enough to cover the facility's peak load, and the lack of storage meant excess solar generation was often exported at low value.
The SolarComtech Solution
SolarComtech designed and installed a 500kW/1MWh Battery Energy Storage System (BESS) seamlessly integrated with the existing solar array and managed by the SC-Vision Standard platform. The solution was programmed for intelligent peak shaving and solar self-consumption optimization:
- Peak Shaving Algorithm: The BESS automatically discharges during the utility's defined peak hours, reducing the facility's grid demand to near zero when rates are highest.
- Solar Optimization: Excess solar energy generated during the day is stored in the BESS instead of being exported, maximizing the value of the on-site generation.
- Resilience: The BESS provides critical backup power for essential operations, ensuring business continuity during brief grid disturbances.
The Results
95%
Reduction in peak demand charges during the first year of operation.
$450,000+
Annual savings realized from energy cost avoidance.
< 4 Years
Projected payback period for the entire BESS investment.
Conclusion: The integrated solar and storage solution provided the client with unprecedented control over their energy costs, turning a major operational expense into a predictable, manageable asset.
