Why It Matters to Hosts
Commercial-grade energy storage for essential retail sites
OpenGrid deploys professionally engineered, behind-the-meter battery energy storage systems designed for long-term commercial operation at grocery-anchored and essential retail properties.Installed at the main electrical panel, our systems reduce peak demand exposure, support resiliency, and integrate seamlessly with site operations.
Where It Sits
Energy storage connects directly at the main meter and panel behind the utility meter, working alongside your existing site electrical infrastructure.
Fully integrated into your site’s electrical distribution
No bypassing or rewiring of core building systems
No disruption to refrigeration, lighting, or point-of-sale operations
Installed to commercial electrical codes and standards
Why It Matters to Hosts
High-Performance Energy Infrastructureesigned for long-termcommercial sites
OpenGrid utilizes the PowerStack Liquid Cooled C&I Energy Storage System, a high-degree integrated system designed for maximum safety and efficiency at commercial sites.
Precision Thermal Management
Innovative liquid cooling maintains a cell temperature difference of 2.5°C, cutting daily heat loss by 40% and extending the life of the asset.
Triple-Layer Safety
Features integrated three-level fire prevention with early warnings for thermal runaway and dedicated water-based fire suppression.
Seamless Integration
Pre-commissioned cabinets are designed for side-by-side installation, creating a clean, professional footprint that reduces on-site work.
Industrial Capacity
Each unit delivers 257 kWh of nominal capacity, providing robust power support for grocery-anchored operations.
Core Capabilities
Demand charge reduction:
Battery storage is designed to reduce short-duration peak demand events that drive utility demand charges.
Load shaping & site support:
The system smooths net load and provides controlled, responsive discharge during peak intervals.
Resiliency enhancement:
Energy storage provides on-site capacity to support load stability during grid events.
Supports optional EV charging:
When paired with EV chargers, storage helps manage incremental load without burdening the site.

Why It Matters to Hosts
EV Charging
When feasible, OpenGrid can include EV charging as part of the system, connected at the main panel and optimized by our operations team. Battery integration helps manage incremental charging load without materially increasing site peak demand. EV charging remains optional and site-specific.
Example configuration (OdeumOne integrated DCFC):
50 kW rated output
CCS1 and NACS connectors
36.8 kWh integrated LFP battery
OCPP 1.6 JSON (2.0.1 upgradeable)
Payment via QR, credit card, or RFID
