MISO对煤炭投掷一条短救生索，反之亦然

由于MISO的容量竞标的结果和今后的容量不足的警告，这个夏天，陆续发表了为了缓和至2025年的市场窘迫，煤炭发电厂的退役延期。MISO向FERC申请将Rush Island(1,195MW)指定为SSR，MISO判断退役将使供电网的可靠性暴露于危险中，因此是为了确保成本回收。

可是，今后10年，由于供应链的后退而导致的短期产能短缺，以及再生能源大量引进预计长期性容量不足，需要不仅这个发电厂维持上线状态。电力公司清洁能源目标，环保法规，老化，经济理由等，所有人都竞相将煤炭排除在系统之外，不过，由于维持固定容量的必要性，加速退役是有限度的。问题并非缺乏理由和动机，现实上MISO确保替代容量并不容易。

本报告提供MISO的煤炭发电厂的退役延期发表相关资讯。

Report Summary:

Following the Midcontinent System Operator's capacity auction results and warnings of upcoming capacity shortfalls, a wave of coal plant retirement delay announcements rolled in this summer in an effort to mitigate market tightness until 2025. MISO just filed with FERC to designate Rush Island (1,195 MW) a SSR, which will guarantee cost recovery after MISO found its retirement would endanger grid reliability. However, it is not the only plant that will be needed to stay online in the following decade, as capacity tightness is projected in the near-term due to supply chain setbacks and long-term despite a high amount of renewables entering the system. Utility clean energy goals, environmental regulation, age and economic reasons will all compete to pressure coal off the system, but the need to retain firm capacity will put a cap on accelerated retirements. The issue is not a lack of reason or motivation, but the reality is that replacement capacity is not easy to come by in MISO.
