Elysia Battery Intelligence for BESS

Elysia shows what your site can really deliver, explains where performance is being lost and helps you identify the actions that could recover value.

It connects battery intelligence, workflow and on-site control so operators can move from evidence to action.

Your BESS is only valuable when it performs

You invested in a certain amount of power and energy. But can your team see and trust what each asset can deliver?

Some battery data is not visible to asset operations teams. Other signals, including state of charge, can be inaccurate, distorting dispatch, maintenance and trading decision. As portfolios grow, teams must manage more data and operational complexity, often with limited time and tools.

The result can be unused capacity, avoidable downtime and lost revenue. 

Turn your battery data into better decisions

Elysia BESS Copilot is a suite of performance engineering solutions for grid-scale energy storage. It shows what your site can really deliver, identifies where performance is being lost, explains the cause and helps prioritise the action most likely to recover value. 

  • Performance diagnostics

    Unexplained availability shortfalls can leave capacity unused. Elysia monitors, diagnoses and prioritises issues to help recover available capacity.

  • Maintenance workflows

    Service and RMA actions can be difficult to coordinate across a growing fleet. Our software automates preventative maintenance and service workflows to improve O&M efficiency.

  • EMS power optimisation

    Uneven power allocation can lead to unexpected derating and inverter shutdowns. Our software integrates with the energy management system to optimise power allocation across power conversion systems, helping protect full-power hours.

  • Real-time signal correction

    Inaccurate battery signals can undermine market decisions. Our software corrects state-of-charge, state-of-energy and telemetry data to support more reliable operations and revenue capture.

  • Cell-level anomaly detection

    Thermal issues need to be identified early. Our software flags cell-level anomalies and thermal precursors to support protective action.
