Impacts of heatwaves on electricity reliability: Evidence from power outage data in China.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Heatwaves, driven by climate change, have increasingly challenged energy systems with increased demand and reduced supply, leading to power outages. This study empirically examines the impact of heatwaves on power outages, employing fixed-effects models and using high-frequency outage data from China (2019-2021). The results indicate that heatwaves increase the frequency of outages by 3.9%-4.0% and extend their duration by 7.9%-8.3%. Additionally, each degree of temperature rise increases outages by 0.1%, and an additional heatwave day raises outages by 0.5%. We also observed heterogeneity in outage impacts across different socio-demographic groups. Furthermore, projections under RCP2.6, RCP4.5, and RCP8.5 show that outages will increase by 5.2%-12.5% in 2030 and 7.4%-20.3% in 2050. These findings underscore the urgency of grid upgrades and provide insights for resource allocation to adaptation to climate change.
