Same math as the index

Capture Rate Explorer

What would your shape have captured? Pick a preset profile and a zone — realized market value, capture rate and negative-price exposure over the window, computed through the exact library the public index uses. Custom 15-minute profile upload (your actual asset) is the POST /v1/capture/profile API — Scale tier, 3 free runs/month.

Presets are stylized hour-of-day shapes (disclosed in the page source) applied uniformly across the window — a screening tool, not a yield model. Your real 15-minute meter data through the API gives the true number. Derived statistics computed by Voltcast; prices from published day-ahead auction results.
