Germany's clean spark spread widened to roughly €74/MWh on 30 June, its best reading since the early-June heat series 1. Take the day-ahead high, subtract about €88 of gas input and €32 of carbon at a 50%-efficiency CCGT, and the gross generating margin lands there. Three weeks earlier the same spread sat near EUR -8 to -9, with CCGTs losing money on every dispatched megawatt .
The carbon leg moved too. EUA (EU Allowance) permits slipped to €79.25 on 29 June, briefly losing the €80 handle, then recovered to €80.17 on 30 June 2 . EUA had first broken above €80 on 25 June, and holding that level keeps the carbon cost near €32/MWh.
That €32 carbon charge is what holds the German margin in check. Strip the permits out and the same day-ahead high would clear a spark spread well above €100. The reversal from three weeks of losses tracks the day-ahead rather than any fall in gas: at an unchanged €88 fuel leg, the power price alone turned the spread positive.
