The residents of the United States of America are amidst a deadly heat wave, with temperatures going through the roof across many states. In this crisis, Americans aren't only ones under stress, but so are our power grids. These power grids were not initially created to withstand triple digits, and the consequence to the poor infrastructure is clearly demonstrated through power outages, providing dirty energy, and pushing air conditioning usage to the point where low-income families cannot keep up.
Infrastructure. Energy. Residents. All of the following are under strain, affecting the quality of life, particularly for older Americans, outdoor workers, and infants. It is clear to us that heatwaves are causing massive grid stress, warranting our attention in creating strategies like renewable energy and infrastructure upgrades.
What does a human do when it gets extremely hot? They turn on the air conditioning. Now, when an incredible number of people turn on the air conditioning at the same time because of the heat wave, it puts stress on the power grid. The outdated infrastructure of the power grid makes it unable to handle the pressure coming from all directions, ultimately leading to a power outage. The increased pressure on the power grid from the electrical demand forces the power grid to complete its task by providing dirty energy. In fact, Energy Digital states that "37% of the increase in electricity demand in the US from April to September 2024, compared to the same period in 2023, was due to higher air cooling needs. This led to an increase in coal and gas electricity generation to meet the higher demand."
One of the efficient ways to relieve stress from the power grids is by managing electricity at times when the demand is high. Demand Response has a whole different course of action to address the situation, where instead of trying to produce more power that could potentially be dirty, the electricity is shifted to avoid blackouts. The company can call residents and ask them to temporarily reduce their electricity usage. Examples can include unplugging non-essential appliances and delaying the charging of electric vehicles. Powermag supports the idea by saying it improves the resilience of power grids, "incorporating distributed generation resources [such as renewables] closer to demand points, improves resilience".
Another efficient resolution to the power grid crisis is improving the physical systems of the power grid itself, like power lines, substations, transformers, and control systems. Improving these systems will make the power grid much more reliable during a heatwave, as it can resist the high temperature with its modern and stronger infrastructure. These changes are heavily needed, as older generation infrastructure did not expect the temperatures and energy demands of today. On the other hand, extreme heat in a heat wave can make the equipment overheat, increasing the risk of a blackout. Power grid failures have also been a primary contributor to wildfires, like the 2018 Camp Fire in California and the Smokehouse Creek fire in Texas, where both these incidents were caused because of a power grid malfunction.
