European gas at €66/MWh as storage lags last year and power prices run hot

Dutch TTF wholesale gas printed €66.1 per MWh. EU underground storage is 62% full — about 13 points thinner than last year. German next-day electricity printed €142/MWh. Energy Stress sits near 59 (Stressed). Tighter fuel and grid conditions, not a blackout.

The Dutch TTF hub is the usual European wholesale gas benchmark for heating, industry, and power-plant fuel. On 23 August 2026 the exchange average printed €66.1 per MWh — up from €62.9 on 17 August and €59.8 at the end of July. A higher print tightens the energy system; it is not by itself a shortage claim.

EU underground gas storage stood at 62.3% of capacity on 21 August, 12.8 percentage points below the same date a year earlier. Inventories are the continent’s winter buffer. A thinner fill raises price and shortage risk later in the season — not a same-day outage.

Next-day electricity followed the fuel. Germany printed €142/MWh, the Netherlands €140, Belgium €137, Austria €167, and northern Italy €189. France printed €103/MWh; Spain €80.2 and Portugal €89.3 were the softer western prints the same day. French grid demand printed 40.1 GW on the national operator feed.

Energy Stress sits near 59 (Stressed) after folding fuels and electricity into one lane. That is an index reading on published prices, storage, and load — it does not mean the lights went out.
