No login. Aggregates carry differentially-private Laplace noise (ε = 1, k ≥ 5). The marginal-party column shows a technology bucket only (coal/gas-peaker/wind/solar/cross-border). Raw participant identity is suppressed when fewer than 5 sellers cleared in the hour. Source data: CSV · JSON  ·  low-bandwidth (text-only)
