California. Oversupply of energy from wind and sun

There is no data available yet on California wind power production, which I promised to cover in the next post with the intention of comparing wind power supply data in both countries. On January 11, 2021, which ends just now, a summary of the data from the department was published Oversupply and constraintswhich I find very interesting due to the adoption in the European Union of striving to maximize the use of green energy. Each country in the European Union is to rapidly eliminate coal, oil and gas from the energy sector, and actually from the entire economy. I have described these bureaucratic plans many times, so today I highly recommend the text published on December 27, 2020 on the personal blog of prof. Konrad Świrski – link: Tthe triumph of the green revolution lies ahead a decade that will change everything

California has long been decarbonized. Investing in renewable energy sources simultaneously causes an oversupply of energy from these sources. This is represented by the original multi-year chart with monthly constraints data. The restrictions apply to a greater extent to solar energy.

Please remember that zeros after the decimal point do not mean quantities less than one. This decimal treatment means a change of MWh to GWh. The headache due to the need to develop excess capacity usually falls on local producers of green energy. Last year, there was an increase of over 60% compared to 2019. The oversupply in 2020 constitutes 40% of the oversupply from 2014-2020.

I enter the main text from the CAISO website linked above into my diary:

Managing oversupply. California ISO works to meet the state’s renewable energy targets and supports California’s leadership in the global movement to decarbonise the electrical sector. ISO is ready to integrate additional renewable energy sources into the grid while maintaining safety, cost-effectiveness and reliability.
