Chile loses $562 million to rising solar and wind curtailment
Ember says Chile has curtailed 11,900 GWh of renewable generation since 2022 due to grid congestion, costing operators $562 million.
Cypriot startup unveils new device to reduce solar curtailment
Cyprus-based Enerthon has developed a smart zero-export control device that prevents PV export losses from curtailment by directing generation to self-consumption. Certification is expected soon.
Renewables overbuilding, proactive curtailment can reduce Europe’s energy system costs
New research from the Netherlands showed that renewables and short-term storage can meet around 92.5% of Europe’s electricity demand in future energy scenarios, with the remaining 7.5% being satisfied by green hydrogen. The scientists considered Europe as fully self-sufficient with zero import-export of power or hydrogen, with each of the 37 countries included in the modeling having a self-sufficiency rate of at least 80%.
Hydrogen can mitigate curtailment in floating PV-pumped hydro energy storage systems
Scientists at Italy’s University of Cagliari explored the integration of a water electrolyzer with a floating PV-pumped hydro energy storage system. They found that under high curtailment conditions, hydrogen production helped to stabilize system efficiency and lower the levelized cost of electricity when compared to a system without the electrolyzer.
Brazil solar curtailment hits 20% as renewables strain grid infrastructure
Renewables curtailment in Brazil in the first half of 2025 is straining investment and highlighting grid and transmission limits, with analysts calling for clearer pricing and storage solutions.
Brazil PV curtailment hits 14% as Voltalia seeks compensation deal
Voltalia has reported a 14% cut in its Brazilian PV output in the first half of 2025. The company expects curtailment to stay near 12% to 15% until 2027 and ease from 2028.
Solar power curtailment rises in California
Curtailment – the intentional reduction of power production – continues to rise for both solar and wind power in California.
PV curtailment jumps 97% in Germany in 2024
Solar curtailment increased by 97% in Germany last year, driven by rapid growth in PV deployment and unusually high solar radiation in the summer, according to the Federal Network Agency (Bundesnetzagentur).
China scraps energy storage mandate for renewable energy plants
In a major policy shift toward electricity market liberalization, China has introduced contract-for-difference (CfD) auctions for renewable plants and removed the energy storage mandate, which has driven up to 75% of national demand to date. S&P Global expects the move to reverberate through the global battery storage supply chain, further driving down prices already at historic lows.
Cyprus curtails 29% of renewable energy in 2024
Cyprus curtailed 29% of its renewable energy in 2024, a record high that signals risks to the island’s energy transition.
