Battery Energy Storage Systems
Battery Storage
Battery energy storage systems (BESS) store electricity and discharge it when required by the grid, a facility, or an integrated energy system. BESS can be deployed as a standalone asset or combined with solar, onsite generation, or microgrids to support grid flexibility, manage demand, provide backup power, and improve the use of renewable generation.
Intelligent system controls monitor operating conditions and determine when batteries should charge or discharge based on project objectives, facility loads, market signals, and grid requirements. Each battery storage project requires site-specific evaluation of system capacity and duration, equipment configuration, interconnection, controls, supporting electrical infrastructure, safety requirements, commissioning, and operating objectives.
Storage Supports Energy Resilience and Cost Management
Reliability & Resilience
A properly designed battery storage system can support critical loads during an electricity disruption and may be sized for selected equipment or broader facility needs. For grid-scale applications, storage can respond quickly to shifts in electricity supply and demand and support grid stability.
When paired with solar or onsite generation, battery storage can extend the use of locally generated electricity beyond production hours and provide additional flexibility during changing operating conditions.
Time-of-Use Management
Electricity rates may vary by time of day or based on shorter billing intervals, particularly for commercial and industrial customers. Battery storage can charge when electricity rates are lower or when excess solar generation is available and discharge when rates are higher.
This approach can help facilities manage exposure to time-of-use pricing, depending on the applicable utility tariff and system configuration.
Demand Reduction & Peak Shaving
Utility demand charges are generally based on a customer’s highest electricity usage during a billing period or specified interval. Battery storage can discharge during periods of peak demand to reduce the amount of electricity drawn from the utility grid.
Storage systems equipped with intelligent controls can monitor facility loads and dispatch stored energy when demand approaches established thresholds. Potential savings depend on the utility tariff, facility load profile, battery capacity, and operating strategy.
Demand Response Participation
Subject to program and market requirements, battery storage may enable commercial and industrial facilities to participate in demand-response programs without significantly reducing onsite operations. Systems can discharge stored energy in response to utility or market signals, helping support grid needs while creating potential revenue or cost-management opportunities.
Support High-Demand Electrical Loads
Battery energy storage can help facilities manage new or concentrated electrical loads by reducing peak grid demand and providing additional operating flexibility. Applications may include industrial equipment, data centers, fleet-charging infrastructure, manufacturing operations, and other energy-intensive facilities.
A battery storage system can charge during lower-demand periods or when excess onsite generation is available and discharge when facility demand increases. Depending on system design and utility requirements, this approach may help manage demand charges, address electrical-capacity constraints, and reduce the impact of large loads on existing infrastructure.
For facilities operating electric vehicle fleets, battery storage can help manage simultaneous charging demand and schedule electricity use around operating requirements and time-of-use rates. Base system capacity and operating strategy on the facility’s load profile, charging schedule, available electrical capacity, utility requirements, and long-term energy needs.
Support Renewable Energy Integration
Battery energy storage can help integrate solar and other renewable resources by storing electricity for later use. By increasing grid flexibility and shifting energy use across time, storage can reduce curtailment and support more efficient use of available renewable generation.
When paired with solar, a battery energy storage system can extend the use of solar-generated electricity beyond production hours and reduce reliance on grid electricity during periods of peak demand. Environmental benefits vary based on how and when the system is charged and discharged, the source of the stored electricity, and the regional electricity supply mix.
