IT-NORD · battery revenue index
What a battery earns in Italy North
The daily BESS revenue index for IT-NORD: perfect-foresight day-ahead arbitrage per MW — the transparent, reproducible ceiling — for standard 1h, 2h and 4h assets, methodology-versioned (BESS-v2) and never restated. Real projects earn less; the explorer haircuts it with your exact efficiency, cycles, availability and degradation — and shows what trading on our forecast (instead of a crystal ball) actually captures.

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-NORD 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.
