German Power Prices Skyrocket Past French Levels

German power prices for May have reached approximately four times the level seen in France, marking a record disparity. This significant divergence stems from the disruption to natural gas supplies, exacerbated by the ongoing conflict in the Middle East, which amplifies pre-existing differences between the two European energy markets.

France benefits from a stable, low-cost electricity supply primarily derived from nuclear and renewable sources. In contrast, Germany, which closed its nuclear reactors in 2023, relies more heavily on fossil fuels. Consequently, evenings with low wind or solar output necessitate the use of coal- or gas-fired power plants, driving up German electricity prices.

Utilities in Germany have attempted to mitigate rising gas prices by increasing coal-fired generation. However, their capacity to shift further is constrained by a significant number of coal plants already closed under the country's energy phase-out policy. The German government is exploring options such as reactivating reserve or decommissioned coal units to address the crisis.

Furthermore, concerns over French power exports, particularly during spring periods when grid operator RTE has previously curtailed cross-border flows, contribute to the price gap. Such restrictions can depress domestic prices in France by limiting excess electricity sales and simultaneously increase prices in neighboring countries like Germany.
