Was ein Batteriespeicher in Kosovo verdient
Der tägliche BESS-Erlösindex für XK: 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 XK 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.
