Vattenfall CEO warns European gas refilling cost will drive up winter power prices
Anna Borg told Montel on Friday that restocking storage will be costlier than desirable, with a direct pass-through to electricity prices this heating season.
The cost of restocking European gas storage ahead of this winter will run above desirable levels and push power prices higher, Vattenfall chief executive Anna Borg told Montel on Friday (2026-07-17). Borg leads the Swedish state-owned utility that generates and sells power across several northern European markets, making her statement an operational view rather than an analytical scenario.5
ICE Endex TTF front-month was at €57.51/MWh as of Friday morning (2026-07-18), with German day-ahead power at €113.24/MWh on the same date. Neither level yet fully reflects the cost of whatever additional gas purchasing an accelerated refilling campaign would require.5
Gas sets power prices across much of north-western Europe for most winter hours. That is the transmission mechanism Borg is pointing to: competitive purchasing to top up storage pushes TTF higher, and higher TTF translates into higher marginal generation costs for the gas-fired plant that clears the market. Industry experts told Montel in May (2026-05-21) that gas would remain the dominant driver of European power market volatility through the year, with any shortfall in injection rates amplifying the signal.1
Refilling at tolerable cost means competing for Atlantic LNG. But that market is under mounting pressure from Asian demand. JKM, the benchmark for delivered LNG in northeast Asia, stood at $20.98/MMBtu on Friday (2026-07-18), against NYMEX Henry Hub front-month at $2.91/MMBtu. Whether flexible US cargoes head west to Europe or east to Asia turns on whether European hub prices offer a sufficient premium over Asian delivered costs after shipping and liquefaction.4
Consultancy ICIS argued in June (2026-06-11) that European gas prices would need to rise to attract US LNG away from Asian buyers and complete seasonal restocking. That argument has only grown more pressing as the injection season advances. The competition between European and Asian demand for flexible supply is what determines whether refilling completes at the cost levels Borg described as already higher than desirable.4
Germany's storage position in late May illustrated the injection backlog. Gas Infrastructure Europe data showed German sites at 30.6% full as of May 27 (2026-05-27), well below the 38.65% recorded at the same point the prior year. Slower early progress requires more aggressive and more expensive purchasing in August and September, when competition for both pipeline and LNG flows typically peaks.3
The structural constraint behind all of this is a European gas balance permanently altered by the erosion of Russian pipeline supply. Russia previously accounted for 40 to 50% of European gas imports; that share has fallen sharply, leaving the continent more reliant on LNG and Norwegian flows to sustain injection pacing through summer into autumn.2
Borg is running generation and supply businesses that hedge and dispatch against the same forward curve she expects to rise. Whether ICE Endex TTF front-month needs to move materially from current levels to attract sufficient LNG volume westward, and whether that happens early enough to avoid a winter draw on inadequate reserves, is the trade implication her Friday (2026-07-17) statement leaves open.5,3
