WEM market data explained: how to analyse it using Ko

Wholesale Electricity Market (WEM) battery revenues are built from several moving parts, and pulling them together usually takes a lot of manual work.

Merchant revenues need wholesale prices, dispatch volumes and FCESS enablement. Total revenues then need Reserve Capacity Mechanism payments and Non-Cooptimised Essential System Service contracts layered on top. Without that full stack, it is easy to miss why two batteries facing the same market conditions recorded very different outcomes.

Ko brings these datasets together in the Terminal. It can pull price history, trace facility dispatch, compare merchant and contracted revenue, and show how individual batteries operated through specific market conditions.
