  1. Data center demand could drive a 79% increase in ERCOT power prices by 2027.

    AI + cloud growth is accelerating energy demand fast.

    Energy is no longer just a cost, it’s a strategy.

  2. ERCOT grid weathers winter storm, energy expert praises federal prep order

    Monday’s sunshine proved to be a welcome sight, not just for those who are tired of the snow,…

  3. As #Texas power demand surges, #solar, #wind and storage carry the load
    Together, wind and solar supplied 36% of #ERCOT's total #electricity over those nine months. Solar, in particular, has transformed Texas's daytime energy mix. From June to September, ERCOT solar farms generated an average of 24 gigawatts (GW) between noon and 1 pm -- double the midday output from 2023. That growth has pushed down natural gas use at midday from 50% of the mix in 2023 to 37% this year.

  4. The ongoing travesty of lack of political leadership in Texas. The pattern of inaction is clear - Texas fails to take preventative actions to prepare for disasters. Recent low-lights:

    1) 2008, Hurricane Ike hammered the Texas coastline > 100 deaths, ~ 25B in damages. No action on creating a surge barrier in Galveston Bay.

    2) 2021, massive winter storm crashed the state’s eccentric power grid leaving ~5M people without heat and more than 200 dead. 4 years later, the state’s electric grid operator, Ercot, is warning another similar storm has an 80% likelihood of rolling blackouts.

    3) 2025, Texas hill county floods, > 120 deaths and $Billions in damages. Texas Senate lawmakers killed a statewide initiative to improve emergency alerts with a network of outdoor sirens, a few months prior to the floods in 2025, via bill HB13.

    📌 Summary:
    本文透過分析德州獨立電網 ERCOT 的實際資料,證明再生能源,特別是太陽能,如何顯著降低德州電力成本。從 2018 年至 2024 年,德州夏季尖峯需求由 65 GW 增至 80 GW 同時,太陽能裝機容量大幅提升,尖峯發電量從 1.2 GW 激增至 18.8 GW。由於電力價格由「邊際發電機」定價,通常是最昂貴的火力發電廠,因此減少火力發電需求即降低邊際成本。太陽能發電減少對火力發電的依賴,使得 2024 年在相同負載下電價比 2018 年低約 40%以上。此報告還計算出若無再生能源擴展,2024 年的電價將高達每兆瓦時 55 至 90 美元,遠高於實際約 39 美元。作者強調,雖然過去補貼促進再生能源發展,但目前補貼規模不大,成本下降主要源自技術進步與市場機制。此外,文中也指出儲能系統如電池對降低尖峯價格及提升電網穩定性的正面影響。最後,作者提醒再生能源成本效益不可簡單外推至 100% 再生能源的電網,並指出相關政策及市場設計對未來能源轉型的重要性。

    🎯 Key Points:
    → 再生能源擴展與電價下降:2018 至 2024 年間,德州太陽能發電量大幅成長,帶動邊際火力發電需求下降,價格隨之降低。
    → 邊際發電機機制解析:ERCOT 採用邊際成本定價,最貴的發電廠決定價格,故太陽能量越多,火力需求越低,整體電價越低。
    → 實際數據計算:2024 年 8 月平均電價約 39 美元/MWh,若依 2018 年價格負載曲線,價格估計在 55-90 美元/MWh,證明太陽能帶來經濟效益。
    → 儲能系統角色:電池等儲能裝置平抑電價波動、減少高峯時段價格飆升,並帶來市場利潤,儲能日益普及。
    → 補貼與政策影響:過去補貼助攻再生能源成長,當前補貼已縮減,未來市場及政策仍是推動能源轉型關鍵。
    ★ 強調再生能源並非花錢「燒錢」,反而拯救消費者數十億美元電費支出。
    ★ 警示不宜盲目將此成果推展至 100% 再生能源系統,因穩定性及成本挑戰不同。
    ★ 提及德州電網孤立限制了輸出,多國互聯及地區儲能將是下一步挑戰與機會。

  6. Wonder why wind, storage & other climate techs matter in the current climate?

    Here's a live view of Texas's electricity mix: wind tops the list, energy storage plays a key role. The second biggest source: solar. (There's a CKI deep-dive for solar, too.)

    Wind, solar & batteries don't dominate Texas's grid because of state-level policies & regulations. Quite the opposite.

  7. The Greater Houston area will remain under a freeze warning until 9 a.m. Monday morning, according to the National Weather Service. A cold weather advisory warning of freezing wind chills will remain in place until 11 a.m.
