I agree, the other thing missing is it's involvement with the WorldCom one as well which was even bigger. Unfortunately, I can't put any original source information due to wikipedia rules so I guess it will never be known \o/2603:8000:CE01:B380:AC16:8E49:934A:4DEA (talk) 10:18, 27 October 2022 (UTC)

Advert?

Why is there an advert tag to this? It seems pretty factually neutral, even though all the links are to the CAISO website, which is unsettling. 128.8.65.25 (talk) 14:26, 29 July 2013

Correction regarding "Deliberate 2020 rolling blackouts"

The following is a correction regarding the "Deliberate 2020 rolling blackouts" section:

On August 14 and 15, 2020, the California Independent System Operator Corporation (CAISO) was forced to institute rotating electricity outages in California in the midst of a West-wide extreme heat wave. Between Aug. 14 and 19, 2020, California experienced temperatures 10-20 degrees above normal, and the rest of the West endured record or near-record highs of 5-20 degrees above normal. Several wildfires were burning in proximity of major transmission lines.  Collectively, the heat and extenuating conditions stressed generators, causing some to fail or reduce output.  At 6:38 p.m. on Aug. 14, the CAISO declared a Stage 3 Emergency because it did not have sufficient resources remaining to meet its reserve requirement. A controlled load shed was necessary to allow the CAISO to recover and maintain its reserves. The reserves are required as a contingency in case of an additional significant loss of transmission or generation. Without shedding load and recovering reserves, the CAISO risked causing uncontrolled load shed and destabilization of the western power grid. By 7:40 p.m., the CAISO began restoring shed load as system conditions improved. A total of 491,600 customers were affected for time periods ranging from 15-150 minutes.

On Aug. 15, similar weather and fire conditions persisted. In the afternoon, solar generation dropped due to cloud cover, and in the evening, wind generation stalled. At 6:28 p.m., the CAISO declared a Stage 3 Emergency, again, because it couldn’t meet its reserve requirement. At 6:48 p.m., wind production increased and the emergency was cancelled. A total of 321,000 customers were affected for time periods from 8-90 minutes.

Following these emergency events, Governor Gavin Newsom requested the CAISO, the California Public Utilities Commission (CPUC), and the California Energy Commission (CEC) report on the root causes of the events leading to the August outages.

The analysis found that the August outages were related to extreme weather conditions, resource adequacy and planning processes, and market practices. The factors identified were:

1. The climate change-induced extreme heat wave across the western United States resulted in demand for electricity exceeding existing electricity resource adequacy (RA) and planning targets.

2. In transitioning to a reliable, clean, and affordable resource mix, resource planning targets have not kept pace to ensure sufficient resources that can be relied upon to meet demand in the early evening hours. This made balancing demand and supply more challenging during the extreme heat wave.

3. Some practices in the day-ahead energy market exacerbated the supply challenges under highly stressed conditions Electricsolar (talk) 21:07, 11 August 2022 (UTC)

Thank you. Have you got an independent, reliable source to verify that? Storchy (talk) 21:12, 11 August 2022 (UTC)

He provided the very report compiled (like he said) by 3 different government agencies that are independent of each other. What more do you need?2603:8000:CE01:B380:AC16:8E49:934A:4DEA (talk) 10:24, 27 October 2022 (UTC)
