Modo Energy capture rates show how much of a battery’s available revenue opportunity was actually captured.

This metric adjusts revenue potential for the factors faced by each asset, including constraints, MLFs, contracts and availability. This makes it easier to compare how well batteries performed across different regions and operating conditions.

Two batteries can record similar revenues, but one may have captured most of what was available whilst the other left a large share on the table.

Ko can query Modo’s capture rate dataset directly. It breaks down revenue losses by stage, compares performance across states and assets, tracks quarterly trends, and links cycling behaviour with capture outcomes without writing SQL.

Capture rate measures earned revenue against maximum potential revenue

Modo Energy’s capture rate dataset measures how much of each battery’s daily revenue opportunity it actually earned. It covers every grid-scale BESS asset in the NEM from January 2024 to the present.

​The primary dataset is nem_modo_capture_rates. It tracks five stages of potential revenue, then compares them with actual revenue for each asset and date.

Potential revenue starts with the theoretical ceiling. This assumes a battery could charge at the lowest-priced intervals available and discharge at full capacity during the highest-priced intervals, cycling once per day. Each stage then applies a real-world adjustment.
