Demand Limiting

Operating Mode

Active and/or reactive power limiting (from grid)

Objective

Reduce demand charges and maximize use of onsite resources

Spirae Solution

The Energy Storage Management application monitors facility energy demand, automatically discharges storage devices to keep net demand below set level, and maintains desired state of charge based on operating conditions

Benefits

Demand charge reduction and maximum use of local renewables

Load management

Operating Mode

Load-responsive charge/discharge

Objective

Control net load using storage assets as flexible resource

Spirae Solution

Discharge storage assets when load exceeds setpoint and charge when loads fall below setpoint or other conditions such as electricity cost become favorable

Benefits

Minimize peak electricity charges, consume electricity when costs are low, maximize renewables contribution, valley-filling during low load periods

Renewables Integration

Operating Mode

Net Energy Firming and Ramp control

Objective

Minimize net variability due to renewables production fluctuation

Spirae Solution

Monitor “net” meter (physical or virtual) and dynamically dispatch storage assets while respecting state of charge and other operating constraints

Benefits

Maximize onsite renewables consumption, increase renewables hosting capacity on distribution grids, minimize spinning reserves required for renewables ariability compensation

Market Participation

Operating Mode

Frequency Response

Objective

Create additional value streams for storage assets through market participation

Spirae Solution

Supply firm dispatchable resources to trading desk to bid into frequency response markets and schedule, dispatch, and monitor assets to perform to technical market participation specifications

Benefits

Capture additional value through market participation and bring demand-side resources to bear in ancillary services markets
