The so-called COGIX (COGeneration IndeX) is an indicator for the operating efficiency of CHP-plants, that receive revenues at the wholesale electricity market. It is similar to the spark spread resp. green spark spread including emission costs for greenhouse gases, which is a contribution margin calculated from fuel costs, emission costs and revenues from electricity sales. In the COGIX framework, also the revenues from heat sales of the CHP-plant are considered.

  • Der COGIX (COGeneration IndeX) ist ein Wirtschaftlichkeitsindikator für Kraft-Wärme-Kopplungs-Anlagen (KWK-Anlagen), die am Strommarkt agieren. Ähnlich wie beim Spark Spread, bzw. dem Green Spark Spread inclusive CO2-Emissionskosten, wird ein Deckungsbeitrag aus Stromerlösen und Kosten für Brennstoff inclusive CO2-Emissionen berechnet. Zusätzlich werden beim COGIX auch noch die Wärmeerlöse der KWK-Anlage betrachtet.
