Europe power demand slips week-on-week as warmer weather and May Day holidays curb consumption

Electricity demand weakened across much of Europe in the week of April 20, a pattern that investors will likely read as a sign of softer near-term consumption rather than a broad-based shift in fundamentals. The declines coincided with generally higher temperatures in many countries and were reinforced by holiday effects expected to weigh on usage across large parts of the continent.

Most markets down, with the UK leading the decline

The UK recorded the largest week-on-week decrease, with electricity demand down 5.9%. France followed with a 4.4% decline, while Germany and Italy saw reductions of 4.1% and 3.4%, respectively. On the Iberian Peninsula, the pullback was more modest: Spain fell 0.7% and Portugal declined 0.6%.

Belgium was the only exception, where demand rose slightly by 0.4%. That increase also marked a break after three consecutive weeks of declines.

Warmer conditions lift temperatures unevenly across Europe

Weather played a role in the day-to-day variability behind demand trends, with average temperatures rising across most markets over the same period. Portugal and Spain experienced the strongest increases—up 2.1°C and 1.7°C—while France rose by 1.4°C and the UK saw only a marginal increase of 0.1°C.

Not all countries warmed: several recorded cooling, ranging from a temperature decline of 0.8°C in Belgium to a larger drop of 2.5°C in Germany. The spread underscores that consumption changes are being shaped by uneven regional weather rather than uniform conditions.

AleaSoft forecasts further declines ahead, except in Britain

Looking to the week of April 27, AleaSoft Energy Forecasting expects electricity consumption to fall further in France, Belgium, Germany, Italy, Spain and Portugal. The forecast attributes much of this expected weakness to the May 1 International Workers’ Day holiday observed across much of continental Europe.

In contrast, AleaSoft projects an increase in demand for the British market during that same period—an outcome that would keep the UK distinct from broader European trends as holiday-related load effects take hold elsewhere.
