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. … [continued]
Electricity grid operators often keep a wary eye towards the thermometer, particularly during the summertime danger season, as daily temperatures soar above 90 degree Fahrenheit and heat waves spread around the country. And for good reason: extreme heat events cause a host of reliability issues for the grid. Electricity demand … [continued]
States with decarbonization goals must plan, prepare, and test for long-duration energy storage
Average wholesale electricity prices at major trading hubs in the United States rose throughout much of 2022 and were, at times, volatile as a result of extreme weather events. The limited availability of coal to substitute for higher-priced natural gas also contributed to higher electricity prices. Prices at all electricity … [continued]

California is doubling down on electric vehicles (EVs). Critics say more plug-in cars will strain the power grid. Here’s why they’re wrong.
In the first two weeks of September 2020, average solar-powered electricity generation in the California Independent System Operator (CAISO), which covers 90% of utility-scale solar capacity in California, declined nearly 30% from the July 2020 average as wildfires burned across the state.
The share of variable renewable energy (VRE) — mainly solar and wind — generation on U.S. regional power systems more than doubled on average from 2012 to 2018, according to the newly released 2018 Renewable Energy Grid Integration Data Book.
The utility-scale solar sector has led the overall U.S. solar market in terms of installed capacity since 2012. In 2018, the utility-scale sector accounted for nearly 60% of all new solar capacity, and is expected to maintain its market-leading position for at least another six years.
According to the Union of Concerned Scientists, curtailment of renewable energy is not a problem, it is an opportunity to adjust our use of electricity to a 21st century world.
