CAISO：在緊要關頭出現另一場熱浪

分析總結

9 月初，加利福尼亞經歷了夏末的熱浪，創下了新的電力需求高峰，給該州的電網帶來了嚴重壓力。與 2020 年 8 月中旬的熱浪相似，關注的關鍵時期恰逢淨需求（總需求減去可再生能源發電）的峰值，晚上太陽能發電量增加，這是因為需求沒有隨著供應而減少從市場下跌。然而，與 2020 年不同的是，這一次 CAISO 能夠避免輪流停電，儘管需求創紀錄且水電減少。這一成功是多種因素的結果，包括增加的電池存儲、新的和擴展的需求響應 (DR) 計劃，以及 CAISO 大型燃氣發電廠的持續靈活供電。由於對加利福尼亞未來的熱浪既樂觀又悲觀，積極的規劃對於保持涼爽至關重要。

本報告分析了 CAISO（加利福尼亞獨立電網運營商）在 2022 年夏季的應對狀況和電力危機。

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.
