In its second full year of operation the Saint-Nazaire offshore wind farm produced approximately 1.4 TWh of electricity, a modest reduction relative to the 1.5 TWh recorded in 2023 and below the 1.6 TWh subsequently achieved in 2025. The 2024 result corresponds to a load factor of roughly 33% against the 480 MW installed capacity. According to EDF power solutions' offshore wind asset-management director, the year's weaker wind resource was the principal driver of the lower output, with the December 2023 offshore substation transformer fault and the subsequent return-to-service period contributing only marginally on a full-year basis. Monthly production exhibited the usual seasonal envelope (around 168 GWh in February 2024, falling to about 70 GWh in August 2024). Notwithstanding the lower headline figure, the year was the first in which full plant availability returned after the early-2024 substation restoration, and operational reliability and predictive-maintenance routines stabilised. The 2024 production was reported by the operator as broadly in line with the long-term resource envelope despite running below the 1.7 TWh design-case annual yield, and informed the subsequent operational targeting for 2025 maintenance windows and intervention scheduling.
