Modo Energy’s WEM index is now live (ME BESS AUS WEM), providing a revenue benchmark for batteries in Western Australia’s Wholesale Electricity Market.

Built from Modo Energy’s asset-level performance data, the index applies a consistent methodology tailored to the WEM. It gives asset owners, investors, analysts, and developers a common reference for comparing battery revenues.

Why is it useful?

The WEM index helps put individual asset and portfolio revenues in the context of wider market performance. Use it to:

• Track market trends: see how battery revenues change over time.
• Benchmark an asset: compare a battery’s revenues with a relevant peer group.
• Assess portfolio performance: compare a fleet against the wider market or a selected group.
• Support investment and financing analysis: use historical revenue evidence to evaluate a project’s assumptions.
• Provide a reference for financial swaps: manage exposure to battery revenues through contracts settled against an agreed index. See how SSE and Statkraft used a Modo Energy index.
