CAISO：在紧要关头出现另一场热浪

分析总结

9 月初，加利福尼亚经历了夏末的热浪，创下了新的电力需求高峰，给该州的电网带来了严重压力。与 2020 年 8 月中旬的热浪相似，关注的关键时期恰逢净需求（总需求减去可再生能源发电）的峰值，晚上太阳能发电量增加，这是因为需求没有随着供应而减少从市场下跌。然而，与 2020 年不同的是，这一次 CAISO 能够避免轮流停电，儘管需求创纪录且水电减少。这一成功是多种因素的结果，包括增加的电池存储、新的和扩展的需求响应 (DR) 计划，以及 CAISO 大型燃气发电厂的持续灵活供电。由于对加利福尼亚未来的热浪既乐观又悲观，积极的规划对于保持凉爽至关重要。

本报告分析了 CAISO（加利福尼亚独立电网运营商）在 2022 年夏季的应对状况和电力危机。

Report Summary:

Early September brought a late-summer heat wave to California that resulted in record peak demand and severely stressed the state's power grid. Just like the mid-August 2020 heat wave, the key hours of concern aligned with peak net demand (gross demand less renewable generation), which occurred in the evening hours as solar generation waned, but demand remained strong. However, unlike 2020, this time CAISO managed to avert rolling blackouts despite the record demand and reduced hydro generation. This success is the result of several factors: the growth of battery storage, new and expanded demand response programs, and the continued flexibility provided by CAISO's critical gas-fired fleet. As California looks to future heat waves, there are reasons for both optimism and pessimism, and proactive planning will be essential to keeping cool.
