FCAS & Arbitrage

Frequency Control Ancillary Services (FCAS) and Arbitrage solutions support stability and reliability of the grid’s frequency by maintaining a balance of electricity supply and demand, and generate revenue by directing electricity back to the grid. This revenue can be maximised by joining with eLumina and our preferred energy aggregators that use AI-driven technology to connect and manage various distributed energy resources (DERs).

Key Features:

Revenue Generation

Receive payment for feeding stored energy back to the grid.

Optimised Power Consumption

Eliminate short-term spikes in energy demand and lower costs.

As the energy sector pursues a net-zero target, Frequency Control Ancillary Services (FCAS) and energy arbitrage are tools businesses and grid operators can use to interact with electricity efficiently and profitably.

Selling electricity back to the grid from a full battery
Energy Management Systems (EMS) determine the cheapest source of power (e.g. solar) and best times to send it to the grid
Revenue sharing arrangements between eLumina, customers, and aggregators yield increased financial benefits.
