Electrical outages have increased more than twofold over the past six years, and power networks throughout the United States have collapsed due to numerous weather-related and natural disasters (Reuters). However, as our population rises and severe weather occurs more frequently, the demands on the electricity infrastructure will only keep rising. A sustainable solution, however, is around the corner owing to solar energy.
Solar energy technology provides a safe, effective way to capture and use solar energy to generate electricity for our homes and businesses. You are aware of the various advantages that solar energy may provide for you. Solar power has many benefits, including lower energy costs and a dependable power supply. But did you realize solar can also provide essential advantages to the American electricity grid? This article will go through the fundamentals of power grids, the problems with the American power grid, and why solar energy might be the perfect solution.
How Power Grids Operate
A vast network of power plants, distribution hubs, and transmission lines makes up the American electrical grid. It is designed to offer the vital energy that fuels our nation while balancing the supply and demand for electricity.
Three fundamental parts of Power Grids
- Generation: Fossil fuels or clean energy sources like wind and solar are used to generate electricity at a power plant.
- Transmission: Next, power lines transport high-voltage electricity over large distances.
- Distribution: The power is transformed into lower voltages for usage in homes and businesses at substations after it has arrived. Consumers receive electricity via power distribution lines.
Over 2,000,000 miles of electricity lines, 11,000 power plants, and 3,000 distribution centres make up the U.S. power grid.
How many electrical grids are there in the U.S.?
Although the United States electricity grid is sometimes referred to as a single entity, it is divided into three independent grids: the Texas, Eastern, and Western.
How antiquated is the American electrical system?
Since Thomas Edison unveiled America’s first power plant in 1882, little has changed in the fundamental design of the power system. The basic idea has mostly stayed the same, even if the grid has expanded tremendously.
One of its most significant concerns is that much of the data used to operate the electrical system is independent of what we currently know about climate change. For instance, regional grid operators’ risk models reference weather patterns from the 1970s. None account for the most recent scientific findings, resulting in a severe failure to consider how extreme weather can endanger the grid.
The physical technology utilized in the electricity grid also exhibits signs of aging, so it’s not only the data that needs to be updated. The massive power transformers in the United States, which control 90% of the country’s energy supply, have an average age of more than 40 years. Research has shown that faults sharply rise at the age of 40. Additionally, with a lifespan of only 50 years, roughly 75 per cent of our power lines are older than 25 years.
How reliable is the American power grid?
Unfortunately, the grid has serious weaknesses that will worsen over time. And while renewable energy offers an excellent substitute for highly polluting power plants, significant improvements are required to make it a workable option on a national scale. But for widespread sustainable energy initiatives to be supported, significant changes in how the grid is managed will probably need to occur first.
Who is in charge of the U.S. electricity grid?
With numerous legislative initiatives to centralize regulatory powers, there has been much discussion about who should be in charge of the electrical grid. Today, maintaining grid monitoring is tasked with a “patchwork” of federal and state agencies. Currently, the Federal Energy Regulatory Commission (FERC) of the Department of Energy produces and distributes energy throughout the United States. However, the actual distribution of power is within the jurisdiction of state and local governments. The Environmental Protection Agency was given the jurisdiction to regulate air pollution produced by power plants that supply the American grid in 1970 thanks to the Clean Air Act. The U.S. Supreme Court, however, decided in June 2022 that the EPA lacked the authority to impose broad rules for power plant emissions.
How the American Power System Fails
There are a few significant issues with the American electrical system right now:
- The grid’s reliability is seriously threatened by extreme weather, which is usually made worse by climate change.
- The majority of the grid’s structure is located above ground, where it is more susceptible to weather events; severe weather and natural disasters can easily overwhelm outdated power lines; the steadily rising variability brought on by climate change is increasing energy demand while concurrently reducing the efficiency of both transmission and production.
- According to information from the Council for Foreign Relations, the American grid was created to function in circumstances that don’t exist anymore. We experience more grid failures than ever since the current extremes exceed what was anticipated when the infrastructure was being developed.
The Benefits of Solar Renewable Energy
According to the National Renewable Energy Laboratory, strengthening the American grid is feasible, and the key to success is having a more varied mix of energy sources. What does this mean? Renewable energy sources should be more widely used; we can no longer rely on fossil fuels and nuclear power. This change has been overdue. The complex demands of the electricity system cannot be satisfied by a single energy-producing technique. But by integrating different approaches, we can fortify the grid and get closer to a cleaner, more effective America.
The potential for solar energy to enhance the grid is enormous, according to ongoing research:
- Solar is being investigated as a potential recovery resource to support other power sources in case of a system shutdown and speeding reconnection time from days to hours. Testing in California demonstrated that a new photovoltaic (P.V.) plan reacted extremely effectively to load changes, delivering regulation accuracy close to 30% better than a conventional power plant.
- Additionally, employing solar energy as your energy source can reduce your reliance on the grid on a personal level. Consequently, you can continue to have a steady, dependable source of electricity even when problems arise.
