Reductions in carbon emissions have been a focus of the power sector. However, the sector itself is vulnerable to the impacts of global warming. Extreme weather events and gradual changes in climate variables can affect the reliability, cost, and environmental impacts of the energy supply. This paper analyzed the interplay between CO₂ mitigation attempts and adaptations to climate change in the power sector using the Long-range Energy Alternative Planning System (LEAP) model. This paper presented a novel methodology to integrate both CO₂ mitigation goals and the impacts of climate change into simulations of a power system expansion. The impacts on electricity supply and demand were quantified, based on historical climate-related impacts revealed during fieldwork and existing literature. The quantified effects, together with climate mitigation targets, were then integrated into the LEAP modeling architecture. The results showed a substantial alteration in technology composition and an increase in installed capacities driven by the joint climate mitigation–adaptation efforts when compared with the scenario without mitigation and adaptation (reference). Furthermore, an increase in CO₂ emissions was observed under the mitigation-adaptation scenario compared with the mitigation only scenario, indicating that the power sector’s adaptations for climate change are likely to hinder CO₂ mitigation efforts. Therefore, a nexus between mitigation and adaptation should be exploited in the policy development for a low-carbon and climate-resilient power system.

减少碳排放一直是电力部门的重点。但是，该行业本身很容易受到全球变暖的影响。极端天气事件和气候变量的逐渐变化会影响能源供应的可靠性，成本和环境影响。本文使用远程能源替代计划系统（LEAP）模型分析了电力部门的CO ₂缓解尝试与气候变化适应之间的相互作用。本文提出了一种整合两种CO ₂的新颖方法缓解目标和气候变化的影响纳入电力系统扩展的模拟中。根据田野调查中发现的与气候有关的历史影响和现有文献，对对电力供需的影响进行了量化。然后将量化的影响以及减缓气候变化的目标整合到LEAP建模架构中。结果表明，与没有缓解和适应措施的情况相比，联合采取的缓解和适应气候变化措施，将大大改变技术组成并增加装机容量（参考）。此外，CO ₂的增加与仅采用缓解方案相比，在采用缓解方案的情况下观测到的二氧化碳排放量表明，电力部门对气候变化的适应可能会阻碍CO ₂缓解措施。因此，在低碳和具有气候适应力的电力系统的政策制定中，应利用缓解与适应之间的联系。
