Monthly average wholesale electricity prices at selected trading hubs Data source: S&P Global Market intelligence
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.
CleanTechnica’s Charles W. Thurston recently talked with Doug Karpa, the policy director of the Menlo Park-based Clean Coalition about his organization’s efforts to convince CAISO, the California Independent System Operator of the grid, to treat wholesale distribution-connected solar generators and grid storage more fairly in terms of transmission charges that eventually trickle down to customers.
The road to renewables will not be paved by the environmentalists. Instead, the path is being cut by the accountants, and health care provider Kaiser Permanente is showing how to do it right.
For several years now, there have been increasing complaints from utilities about the resulting load shape from owners with solar systems. This is the so called “duck curve” which has gotten a lot of attention from utility alarmists. In some sense, it has been a way of claiming that rooftop solar is a profound problem for utilities. We will show here that this problem can be (and will be) solved.
