German gas plants ignore cheaper fuel

German fossil-gas generation fell from 4.37 GW on 24 July to 2.09 GW on the 26th and 2.85 GW on the 27th, over the same days that gas itself got cheaper.

Key takeaway

German gas output fell as gas got cheaper, because the merit order had already left these units behind.

German fossil-gas generation ran 4.37 GW on 24 July, 2.09 GW on Sunday the 26th and 2.85 GW on Monday the 27th, falling across the very days the fuel got cheaper.⁠1 The CCGT fleet did not come back, and the reason is arithmetic rather than sentiment.

Dispatch responds to the fuel price only while the plant is close enough to the money for the fuel price to decide the outcome. Once the spread runs to roughly minus €40/MWh, no hour that a wind farm can cover will call a gas turbine, and a few euros off the cargo does not close a gap that size. The merit order had already moved past these units; cheapening their input moved it back by a rounding error.

German storage got there first, stopping its bids for prompt cargoes on 21 July with injection down to 0.8 GWh a day, because a cavern's alternative buyer for a prompt cargo is a gas plant that will not run. No storage reading fresher than 22 July could be sourced this window, so this briefing will not tell you where the fill sits today. What it can tell you is that the demand-side case for refilling has not improved on cheaper gas, and that is the sentence any 2027 or 2028 gas-plant investment case now has to answer: a regime exists in which an eight per cent fall in the fuel price makes the asset less profitable, not more.

Deep Analysis

In plain English

Even though gas got cheaper this week, German gas power stations still ran less, not more. That sounds backwards, but it makes sense once you know that these plants had already stopped being profitable at any price close to what gas actually costs; the problem is not the cost of the fuel; it is that wind power is now supplying so much electricity that gas plants are not needed as often, whatever they burn.

Deep Analysis
Root Causes

Below roughly minus €40/MWh on the spark spread, the fuel price stops being the variable that decides dispatch, because no plausible level of demand clears at a price high enough to cover the plant's marginal cost; cheaper gas lowers that marginal cost only slightly, from around €123/MWh to €117/MWh across this window, nowhere near the €77 to €84/MWh power actually cleared at.

That is why fossil-gas generation kept falling, 4.37 GW to 2.85 GW, through the same four sessions TTF fell 8 per cent: the plant is not being priced out by expensive fuel, it is being priced out by cheap wind, and cheaper fuel cannot fix a revenue problem.

What could happen next?
  • Meaning

    German gas-fired generation now tracks the residual load left after wind and solar, not the TTF gas price, a structural shift from how the fleet behaved earlier in the cycle.
