Wind Farms are turned off, 95% in 2022 and 94% in the first seven months of 2023, even with high winds

Wind and Solar is a LIE, a joke.

Did you know that ALL SOLAR FARMS in the world, cannot operate when the outside temperature is above 86 degrees Farenheit? It’s in the detail people. Look it up.

Then WHY do they place almost ALL Solar Farms IN THE DESERT, where it is almost always, above 86 degrees?

The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation as it balances supply and demand during the rapid growth of wind and solar power in California.

Grid operators must balance supply and demand to maintain a stable electric system. The output of wind and solar generators are reduced either through price signals or rarely, through an order to reduce output, during periods of:

  • Congestion, when power lines don’t have enough capacity to deliver available energy
  • Oversupply, when generation exceeds customer electricity demand

In CAISO, curtailment is largely a result of congestion. Congestion-related curtailments have increased significantly since 2019 because solar generation has been outpacing upgrades in transmission capacity. (84% of the wind farms are turned off, even in high winds.)

In 2022, CAISO curtailed 2.4 million megawatthours (MWh) of utility-scale wind and solar output, a 63% increase from the amount of electricity curtailed in 2021. As of September, CAISO has curtailed more than 2.3 million MWh of wind and solar output so far this year.

Solar accounts for almost all of the energy curtailed in CAISO—95% in 2022 and 94% in the first seven months of 2023. CAISO tends to curtail the most solar in the spring when electricity demand is relatively low (because moderate spring temperatures mean less demand for space heating or air conditioning) and solar output is relatively high.

CAISO has increasingly curtailed renewable generation as renewable capacity has grown in California. In 2014, a combined 9.0 gigawatts (GW) of wind and solar capacity had been built in California. As of July 2023, that number had grown to 17.6 GW. Developers plan to add another 3.0 GW by the end of 2024.

CAISO is exploring and implementing various solutions to its increasing curtailment of renewables, including:

The Western Energy Imbalance Market (WEIM) is a real-time market that allows participants outside of CAISO to buy and sell energy to balance demand and supply. In 2022, more than 10% of total possible curtailments were avoided by trading within the WEIM. A day ahead market is expected to be operational in Spring 2025.
