PEAK SHAVING
Peak shaving
BESS supplies additional power when the facility’s electricity demand rises.
High demand during certain periods creates a need to manage peak power.
Power threshold, peak duration, required support and electricity tariff structure.
Reduces grid power demand during peak periods. Financial benefits must be assessed against the applicable tariff and facility data.
ENERGY SHIFTING
Energy shifting
Store electricity when a source is available and use it when the facility needs it.
Energy availability and periods of higher demand do not coincide.
Load profile, power sources, charging/discharging windows, losses and state-of-charge (SOC) limits.
Schedules charging and discharging without requiring a change to production schedules.
BACKUP POWER
Backup power
BESS can support selected loads during a main supply interruption with suitable grid isolation, transfer and islanded-operation controls. BESS is not assumed to replace a UPS.
Certain loads need to remain powered when the main supply is interrupted.
Priority loads, power, duration, switching and islanded-operation capability.
Improves the ability to maintain operation of designated loads.
Three coordinated functions: storing electricity, supplying power to support the facility and managing operation according to demand.
Illustrative AC-coupled configuration; the actual design depends on the project.
Electricity from available sources is converted and stored in the battery system.
Stored energy is converted into alternating current to support the facility.
The energy management system (EMS) monitors and coordinates charging and discharging according to demand and equipment limits.
Solid lines represent power flows; dashed lines represent data and control signals, with no electrical connection at crossings. The diagram does not show grid export or a dedicated backup configuration.

Interfaces & protection
Connects BESS to the facility’s electrical infrastructure through appropriate protection, isolation, earthing and switching.
Protection settings, isolation, earthing and switching principles.
Suitable applications · Preliminary power and energy capacity ranges · Integration direction
Final specifications are confirmed through technical and financial analysis using project data.
365Energy coordinates the work from survey to handover, with scope and responsibilities agreed for each project.
Survey the existing site and develop the configuration and integration approach.
Coordinate procurement, installation and connection in line with the design.
Check functions, protection and controls, and record acceptance results.
Provide documentation, operating guidance and the agreed scope of support after handover.
After handover: Monitor status, assess data and review charging/discharging schedules where included in the service scope.
A UPS is designed to maintain a continuous power supply to loads. BESS stores and manages energy; its backup function depends on the architecture, switching and load requirements. BESS is not assumed to replace a UPS or provide uninterrupted power.
When there is a defined need concerning peak demand, energy-use timing or loads requiring backup. Compare options using load data, applicable tariffs, capital and operating costs, losses, battery degradation and the value of maintaining loads. Peak shaving does not automatically mean lower electricity bills; combined applications share the system’s power and energy limits.
Total electricity consumption alone is not sufficient. The assessment needs time-based load data, required support power, discharge duration, SOC and equipment limits.
Backup duration depends on available energy capacity, priority-load power, SOC and the system configuration at the time of the outage.
