EUA carbon closed EUR 80.14/tonne on 16 July, down 1.26%, drifting back under the EUR 81 line it had broken on 13 July for the first time since February 1. An EUA is the tradeable permit a generator must surrender for each tonne of CO2 it emits under the EU Emissions Trading System, and it feeds directly into what a gas or coal plant pays to run.
The pullback stayed modest, within about a euro of the break rather than a reversal of it. Carbon slipped in the same window that German power climbed hard, so the two moved apart: one input to the thermal cost stack eased while the demand pulling on that stack intensified. For the spark and dark spreads, a softer EUA trims the marginal cost of running, a small offset against the fuel-and-demand pressure elsewhere in this briefing.
