EUA December carbon allowances broke EUR 81/tonne on Monday 13 July for the first time since February, climbing from a flat EUR 79.04 settlement on Friday 10 July to about EUR 81.35 on a market-data snapshot around 13 July 1. EUA is the EU Emissions Trading System allowance that gas- and coal-fired generators surrender for each tonne of carbon dioxide they burn, so its price feeds straight into the marginal cost of thermal power.
The climb extends an established run rather than opening a new one. EUA first cleared EUR 80 on 25 June and settled EUR 80.17 on 30 June , so the EUR 81 print is the next leg up, not a break from range. Treat the exact 81.35 level with some caution: it rests on a dated snapshot rather than a confirmed exchange settle, while the EUR 79.04 baseline of 10 July is firmer.
With gas firm at the same time, CCGT marginal cost rises from carbon and fuel together, compressing the clean spark spread further just as gas-fired plant picks up the load French nuclear has dropped. The same squeeze showed up on 9 July, when gas and carbon rose together and compressed Germany's clean spark spread rather than the France-Germany spread .
