to Montel Analytics. The agency expects electricity prices in many European countries to fall below zero in the third quarter of 2025 to reach a new high. The latest report
of Montel Analysis, an
energy research Institute, points out that the main reason for the frequent occurrence of negative electricity prices in Europe is the continuous growth of solar power generation. In its summary report on the European electricity market in the second quarter of 2025,
the agency pointed out that the negative electricity price period in almost all European countries has increased significantly this year, and this trend will continue in the future.
In Sweden's SE2 tariff zone, the negative tariff time in the first half of the year to the end of June was 506 hours , ranking first in Europe. According to the report, this is caused by "exceptionally strong hydraulic runoff, transmission bottlenecks, adjustment of market coupling mechanism based on flow, and expansion of renewable energy installation".
In addition, Spain (459 hours) , Netherlands (408 hours) , Germany (389 hours) , France (363 hours) , Belgium (361 hours) , Negative tariff hours in Finland (363 hours) and Western Denmark (326 hours) both exceeded 300 hours .
Montel's analysis attributes the frequent occurrence of negative electricity prices to two aspects: in the second quarter of 2025 (April-June), solar power generation in Europe reached 104.4 TWh, a record high in the same period ; However, the lack of energy storage facilities and the lack of flexibility on the demand side have led to an oversupply of electricity. Jean-Paul Harreman
, Montel's director of analysis, predicts that the duration of negative electricity prices in parts of Europe will reach a record high in the third quarter of 2025. He said this was due to "the continued expansion of renewable energy, but the demand for basic electricity has not kept pace.." Electricity prices in Germany, the Netherlands and Belgium may fall sharply into negative territory in the afternoon, and then rise sharply in the evening as fossil fuel generators start up in the evening.
He added that parts of south-eastern Europe were showing similar trends. "However, limited grid infrastructure and cross-border interconnection capacity will undermine the region's ability to benefit from low electricity price markets in neighbouring countries,
" Harreman said. Earlier
this week, Ember, an energy think tank in London, said the EU's record solar power generation had become a key factor in stabilizing European power supply during the recent heat wave.
