What is a Commercial Energy Storage System?
A commercial and industrial energy storage system, C&I BESS, is a battery energy storage system built for the electrical realities of a business site rather than a home. A residential system cannot simply be scaled up: C&I storage runs three-phase power, operates at higher DC voltages (up to 1000 V compared with roughly 600 V for residential systems), uses industrial-grade components and fire suppression, and carries the UL 9540 certification that most authorities having jurisdiction (AHJs) will expect to see before they sign off.
Discover's C&I energy storage solutions are engineered to simplify the integration process. For example, a commercial battery storage system has to perform reliably, whether it’s reducing demand charges or backing up critical loads. This only happens when the batteries and hybrid inverter/PCS & controls integrate cleanly with each other and the site's existing electrical design. Discover's systems reduce the cost of that integration and the complexity of permitting, driving higher margins for the EPC or installer.
Discover's industrial energy storage range is built around modularity for exactly this reason. These solutions are designed as scalable building blocks. Capacity can be added in stages to hit ROI targets on any project, to hit ROI targets in stages for any size of project, from light commercial installs through to from light commercial installs to large industrial-scale deployments.

Commercial energy storage systems produce ROI in different ways depending on the site.
These are the five applications where we see C&I BESS projects deliver economic value consistently.
PEAK SHAVING & DEMAND CHARGE MANAGEMENT
Accommodates discharge through peak demand intervals, reducing demand charges on a utility bill.
CRITICAL BACKUP POWER & RESILIENCE
UL 9540-certified transfer keeps production, refrigeration and data running through an outage.
EV CHARGING INFRASTRUCTURE
Buffer EV chargers supplied by a constrained grid with energy storage.
OFF-GRID & REMOTE OPERATIONS
Delivers reliable off-grid power generated by solar or gensets for mines, camps and island utilities.
MICROGRIDS/ENERGY INDEPENDENCE
Grid-tied or islanded operation with PV and/or genset integration for sites that can't go dark.
Certified for Permitting
Every Discover C&I system is UL 9540 and UL 1973 certified, with UL 9540A test data available for a fire safety review. Often this is the first question an inspector asks about a commercial battery storage installation. We supply the certification documentation, test reports and datasheets that the permitting package needs.
