Control energy prices (reBAP — regelzonenübergreifender einheitlicher Bilanzausgleichsenergiepreis) are the prices used to value imbalance energy in MaBiS settlement. They are published by the TSOs and received via PRICAT EDIFACT messages.
Imbalance cost calculation — each quarter-hourly imbalance (actual minus scheduled energy) is multiplied by the corresponding reBAP price to determine the financial impact
Monthly cost summaries — the GET /mabis/energy-volumes/{mabis_zp_id}/monthly-summary endpoint uses these prices to compute cost breakdowns per aggregation object
Prices are available once the TSO publishes them via PRICAT messages. For the preliminary billing phase (M+18 WT), provisional prices may be used. Final prices are typically available before the final billing deadline (M+42 WT).
