German Negative Power Price Hours Decline 9.4% in 2026, Bucking EU Trend

Germany recorded 463 hours of negative electricity prices in 2026 through late September, down from 511 hours a year earlier, according to Bloomberg-compiled data — the first annual decline in four years. Negative prices occur when supply exceeds demand, forcing generators to pay to produce. Kpler Ltd. expects Germany's annual total to fall about 13% from 2025. Electricity consumption from May through July was 10% higher year-over-year, per Fraunhofer Institute data. Revised renewable-support rules also discourage solar generation during negative-price periods. The trend diverges from Spain, where negative hours jumped 31% to 703, and France, which recorded 520 versus 493 a year earlier. Analysts cite abundant solar output and elevated hydro reservoir levels in Spain, and expanded solar capacity and higher nuclear availability in France. Despite the decline, German negative-price hours remain historically elevated, underscoring challenges integrating intermittent renewable generation.
