Introducing Wave Distributed Energy Resources Management System

  • Wave DERMS integrates DER resources with other programs such as traditional Demand Response programs. Rather than just calling a DR Event, shape the load to match renewable generation profiles using energy storage, Demand Response assets, distributed generation and renewables.
  • Wave DERMS can integrate to individual devices or to aggregations of devices. Individual devices typically include larger energy storage devices, PV plants, and conventional generation. Aggregation may include home DR programs (thermostats and hot water heaters), residential storage and PV, and EV fleets

  • Spirae Wave manages DER resources for distribution utility operations. Wave DERMS applications work together with existing utility systems to provide visibility and manage DER and use its inherent flexibility to host more renewables and enhance reliability.
  • Wave DERMS is DER type and brand agnostic. It sees the DER world as a portfolio of DER assets with specific capabilities.
  • Wave DERMS can include the Wave Microgrid and Energy Storage applications.
  • Wave DERMS provides value stacking, allowing assets to be grouped, scheduled and used for multiple purposes at different times. The Wave Planning Engine allows users to take load and renewables forecasts into account and plan optimal dispatch strategies across multiple use cases.


  • Increase flexibility: The flexibility to use any DER resource to support many utility use cases makes distribution utility operations flexible and adaptable.
  • Increase efficiency: Increase grid operations efficiency and asset utilization by using DERs to meet grid operations requirements and deferring capital upgrades.
  • Decrease cost: Wave’s vendor-neutral DER management system, with plug and play capabilities, reduces the cost of DER integration
  • Increase renewables hosting capacity: Increase the amount of renewables that can be added to distribution feeders or at the system level without negatively impacting grid operations.
  • Streamline DER adoption: Wave DERMS streamlines DER adoption from DER provisioning and configuration to optimal dispatch and settlements.

Use Scenarios

Demand Limiting

Active and/or reactive power limiting (from grid) at system level or by location (e.g., feeder or substation)

Avoid thermal constraints on equipment, reduce procured energy costs and imbalance charges, provide non-construction alternatives to growth areas.

Spirae Solution
The Wave DERMS applications monitor demand and available resources, dispatching DER according to user-selectable criteria such as low-cost or low-carbon.

Operations cost reduction, maximum use of local renewables and optimal use of storage assets

Load Shaping

DER dispatched to shape load in operations-friendly manner. The classic example is flattening the “duck curve” and reducing ramp rates during periods of high load and renewables volatility.

Monitor and dispatch resources to support high-levels of renewables without heavy investment in low utilization physical assets.

Spirae Solution
Use forecasts of load and renewables to manage energy storage, DR, and other available DER resources to dynamically shape load to stay within desired limits.

Reduce costs through peak reduction, load shifting, and higher utilization of assets
Smooth the combined effects of renewables variability and net load reduction using demand-side resources rather than bulk system resources
Replace lumpy investments in conductors and transformers with granular investments in smart systems

Market Participation

Aggregation of resources to create virtual power plant (VPP) capacity to participate in day-ahead and hour-ahead energy, capacity, and ancillary services markets.

Create additional value streams for DER assets through market participation

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

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


Wave DERMS may be paired with Wave Microgrid functionality to provide resilience to sections of the grid using utility microgrids and behind the meter microgrids


Wave is based on a distributed control strategy that makes it easy to integrate any type of distributed energy resource (generation, storage or loads), visualize and monitor assets, and optimally dispatch them for different applications. Dispatch can be carried out manually, scheduled ahead of time, or performed automatically to meet specific objectives.
The Wave DERMS architecture allows users to selectively mix and match groups of DERs with specific application capabilities. The Wave DERMS client connects to Wave Servers and allows operators to dispatch different DER groups to meet different objectives.
