C&I Storage Planning: Peak Shaving, Backup Loads, and Scalability
Key considerations for commercial and industrial storage projects: peak-shaving economics, backup load segmentation, and scalable multi-unit system design.

Why C&I facilities invest in storage
Commercial electricity bills often include demand charges based on the highest 15-minute average power draw each month. A battery system can shave these peaks by discharging during high-demand periods and recharging when demand is low.
Peak shaving strategy
The battery management system monitors real-time load and triggers discharge when demand approaches a pre-set threshold. For a 500 kW-peak facility capped at 350 kW with a 150 kW / 300 kWh battery, annual demand charge savings can reach tens of thousands of euros.
Backup and business continuity
C&I backup targets business-critical loads: server rooms, refrigeration, manufacturing line controls, or lighting. Size the battery to sustain these loads for the required autonomy period, typically 2-4 hours.
Scalability across sites
For multi-site operations, standardized battery cabinets and a unified monitoring platform simplify procurement, commissioning, and O&M.
