“Europe’s total grid consumption is falling despite electrification”

A falling grid reading is not falling total consumption

There are verified examples of falling demand on parts of Europe’s electricity networks while electric transport and solar expand. The strongest example from recent months is Great Britain’s new minimum transmission-supplied demand in May 2026. However, the latest quarterly figures for total UK electricity demand show growth. A record low for one half-hour and a fall in national consumption across a quarter are different findings. ^[1][3]

The distinction also explains why solar can coexist with electrification and lower measured grid demand. When homes or businesses consume their own electricity, or distribution-connected generators supply nearby customers, less electricity may travel through the transmission network. Those customers still consume electricity. A large solar farm supplying a network mainly changes the generation mix; its output cannot simply be deducted from total electricity use. NESO expressly distinguishes low transmission demand from underlying consumer use. ^[2]

Great Britain: a new grid minimum alongside growing electric transport

NESO reported National Demand of 12.6 GW on 24 May 2026, in settlement period 27, the lowest it had ever recorded at that point. Its April outlook listed the previous minimum at 12.8 GW on 25 May 2025. These are half-hour power observations, measured in gigawatts, rather than monthly or annual energy totals. The June report also records a solar generation peak of 15.2 GW on 24 May, although it does not establish that both records occurred in the same half-hour. ^[1][2]

Electric transport was expanding during this period. Department for Transport statistics show 2.017 million licensed zero-emission cars across the UK at the end of June 2026, 34.0% more than a year earlier. That category includes battery electric and hydrogen fuel-cell cars and excludes plug-in hybrids. These fleet figures cover the UK, while NESO’s system figures cover Great Britain. They establish contemporaneous growth, not an exact calculation of the cars’ effect on the recorded minimum. ^[4]

The broader electricity figures moved upwards. DESNZ’s release of 29 September 2026 puts UK Q2 demand at 76.3 TWh, up 3.4% from Q2 2025, and final consumption at 65.1 TWh, up 1.6%. Transport electricity consumption rose 20% to 4.8 TWh. The falling network minimum therefore cannot support a claim that all UK electricity consumption fell. ^[3]

Germany: a real quarterly decline in 2025, followed by growth in 2026

Germany provides a genuine earlier example. SMARD’s July 2025 release reported Q2 network load of 107.3 TWh against 109.4 TWh in Q2 2024, down 1.9%, while solar electricity fed into the network increased. This is a specific quarter from 2025, not a decline observed in the latest months of 2026. ^[5]

The August 2026 release reports Q2 2026 load of 109.5 TWh, up 1.5% against its revised Q2 2025 comparator of 107.9 TWh. Solar injection simultaneously rose from a revised 29.7 to 31.8 TWh. The chart uses both demand values from this newer release; combining its 2026 value with the earlier unrevised 2025 number would distort the change. Neither comparison isolates solar self-consumption, weather or industrial activity as the cause of demand changes. ^[6]

France, Spain and Denmark show why the wider claim needs qualification

France’s 2025 data show almost flat consumption alongside growing new uses. RTE reports weather- and calendar-adjusted consumption of 451 TWh, up 0.4%, and unadjusted consumption of 446.1 TWh, up 0.9%. Dedicated data centres connected directly to its transmission system consumed almost 1 TWh, versus around 0.8 TWh in 2024. Estimated solar self-consumption rose from 2.0 to 2.9 TWh. RTE includes that self-consumption in national consumption, so rooftop growth is not automatically counted as a national demand reduction. These are completed 2025 observations published in 2026. ^[7]

Spain’s September release likewise contradicts a current national fall: January–August 2026 demand reached 175.858 TWh, up 2.8% year on year, or 1.7% after weather and working-day adjustment. August demand alone was 23.137 TWh, up 3.7% unadjusted, while self-consumption installations generated an estimated 1.6 TWh separately. Growing solar and growing demand can occur together. ^[8]

Denmark adds a completed 2025 observation. Energinet’s Electricity Market Report says national electricity consumption rose in both 2024 and 2025, with notable increases in both years. Solar generation simultaneously rose by around 1 TWh to 4.4 TWh (14% of domestic generation, up from 10% in 2024), while wind output fell 1.5 TWh in a generally low-wind year. This is evidence of rising electricity use alongside rising solar generation, not a rooftop-only measure or a causal estimate. Energinet’s narrative gives no directly comparable weather-adjusted percentage, so Denmark is not included in the country chart. ^[9]
