IT-CNOR · battery revenue index
Was ein Batteriespeicher in Italy Centre-North verdient
Der tägliche BESS-Erlösindex für IT-CNOR: Day-Ahead-Arbitrage bei perfekter Voraussicht, pro MW — die transparente, reproduzierbare Obergrenze — für Standard-Anlagen mit 1, 2 und 4 Stunden Dauer, methodisch versioniert (BESS-v2), nie nachträglich korrigiert. Reale Projekte verdienen weniger; der Explorer rechnet Ihren Wirkungsgrad, Ihre Zyklen, Verfügbarkeit und Degradation ein — und zeigt, was der Handel auf unserer Prognose (statt einer Kristallkugel) tatsächlich einfängt.

How to read these numbers
The index is the arbitrage ceiling: a battery that knew each day's prices in advance, charging the cheapest hours and discharging the most expensive at 90% round-trip efficiency, one cycle per day. It's deliberately simple — simple is auditable, and auditable is the point. Your project's number is lower: forecast error (see the explorer's Volt foresight capture rate), availability, degradation strategy, grid fees. The ceiling's job is to be the stable benchmark those haircuts apply to — comparable across every zone and every year back to 2015, through the 2021–22 crisis the newer indices' histories don't reach.
Where IT-CNOR has the data, the API also returns the day's IDA1-arbitrage figure and the FCR/aFRR capacity alternatives — shown side by side, never summed, because the same megawatt can't do both at once. Full method, including what v2 does not model: methodology.
