The Climate Change Impact on Power Grid Transmission Capacity

Abstract

Proposing practical solutions to mitigate climate change effects on the electrical power system requires a comprehensive understanding and quantification. By conducting an assessment at high grid resolution, this article explores the impact of climate on transmission network capacity, employing established thermal models and a regional expansion plan. The results indicate average reductions of 1.53%, 2.3%, and 0.2% for overhead lines, power transformers, and underground cables, respectively. We propose a quasi-Dynamic Thermal Rating method to counter these effects, estimating maximum capacity. This approach enhances component capacity by an average of up to 35% during winter at the power transformers and up to 14% during nighttime hours for overhead lines. This solution constitutes a viable alternative for electricity operators, to address the dilemma between the necessity of reducing the failure rate/decrease in capacity, and the imperative need for new investments in transmission assets.
