electricity generation. Renewables are continuing to increase their share of the power sector, rising to almost 23 percent of the nation’s electricity supply last year, which was higher than the generation from both coal-fired and nuclear plants. In other words, when the air is hot, gas power plants cannot generate as much electricity.

It has been reported that on August 25, the plant temporarily lost all of its off-site electrical power from the grid, which is essential for its safe operation, forcing it to rely on on-site backup power. That could lead to loss of the cooling ponds, which are needed to cool the plant’s diesel generators, enabling them to function.

Rate design has been a site of experimentation and contestation since the earliest days of electricity provisioning. In the earliest days of electricity provisioning, fixed charges were common in residential rates due to the limits of metering technology. Regulators and policymakers began to reevaluate their approach to rate design.

Gas, which now generates 40 percent of US electricity, is considered by some to be critical to maintain grid reliability. For example, Dominion Energy, an electric and gas utility in Virginia, is planning to build a mammoth 1,000-megawatt gas plant in an area with a high percentage of residents who are people of color and low-income.

These areas experience higher temperatures relative to surrounding areas because they have a denser concentration of heat-trapping surfaces and limited green spaces that offer cooling benefits. Some themes that emerged were the lack of shading trees, vulnerable populations, the need to be creative when cooling, and issues related to water.

We need to make sure regulators like EPA and CARB restrict its usage before it gains a fossil-fueled foothold in the marketplace. This gas is regulated by EPA under its heavy-duty vehicle program, but controls will only be implemented to the extent that EPA requires them under rigorous testing procedures and strong standards.

At any point in the summer, extreme heat could trigger electricity supply shortages and rotating power outages. In reality, a big heat wave could lead to electricity supply shortages and rotating power outages during any summer month, but September is when it’s most likely. How well has California’s grid been performing this summer?
