Commercial battery energy storage systems (BESS) are increasingly used by Ontario businesses to reduce electricity costs, improve power reliability, and support on-site renewable energy. As demand charges rise and grid constraints become more common, battery storage allows businesses to store electricity when it is inexpensive or abundant and use it strategically when demand is highest. Solify designs and delivers commercial battery storage solutions in Ontario that are fully engineered, code-compliant, and optimized for long-term performance.
What Commercial Battery Storage Is Used For
Ontario businesses install battery energy storage systems for both cost control and operational resilience. The most common applications include:
- Peak shaving to reduce peak demand and Global Adjustment charges
- Backup power for critical operations during outages
- Solar integration, allowing excess solar generation to be stored and used later
- Power quality improvements for sensitive equipment
- Reducing or replacing diesel generators
- Preparing for future grid and demand response programs
Example: A manufacturing facility can use a battery to discharge during peak demand hours, lowering its monthly demand charges while maintaining production continuity.
Commercial Battery System Sizes
Solify deploys scalable, modular battery systems sized to match a facility’s load profile and operational goals.
- 50–100 kWh systems are commonly used by small commercial buildings, retail locations, and offices for peak shaving and limited backup power.
- 150–500 kWh systems support industrial and manufacturing sites, providing deeper demand reduction and solar integration.
- 1 MWh to 4 MWh+ systems are designed for large facilities, agricultural operations, and multi-building portfolios that require advanced load management and long-duration backup.
All Solify battery systems are solar-ready and include real-time monitoring.
Ontario Regulations and Compliance
Commercial battery storage in Ontario is subject to electrical, safety, and utility requirements. Solify ensures every project complies with:
- Ontario Electrical Code (including Rule 64 for energy storage)
- Electrical Safety Authority (ESA) guidelines
- UL 9540 and CSA-certified battery and inverter equipment
- Local zoning, fire, and utility interconnection rules
This ensures systems pass inspection, remain insurable, and operate safely over their full lifecycle.
Engineering and Load Analysis
Battery performance depends on proper engineering. Solify conducts detailed demand and load analysis, including interval data review, peak demand mapping, and solar-battery interaction modeling. Critical loads are identified and prioritized so the battery delivers measurable savings and operational value, not just installed capacity.
Installation, Monitoring, and Optimization
Solify provides a fully turnkey installation process, including engineering, ESA permitting, installation, inspection, and commissioning. All work is completed by licensed electricians. Every system includes real-time monitoring, automated peak-shaving controls, solar-first charging logic, and 24/7 remote diagnostics to ensure ongoing optimization.
Commercial Battery Incentives in Ontario
Eligible commercial battery projects may qualify for:
- Save on Energy commercial incentives
- The Federal Clean Technology Investment Tax Credit (up to 30%)
- Accelerated capital cost allowance (CCA) depreciation
- Future demand response or grid services programs
Solify aligns system design and ownership structure with incentive requirements from the start.
