The solar eclipse and its effect on the grid
Solar power has become an increasingly significant part of our energy mix. Since the last big eclipse in 2017, solar energy use in the U.S. has grown. It's now the largest source of midday generation in California and the second-largest source of midday generation in Texas, Florida, other parts of the East Coast, and in the Southwest.¹ Solar power’s popularity can be credited to its sustainable, renewable, and abundant nature — at least when the sun is shining.
When a solar eclipse occurs, like the one headed our way on April 8, the amount of sunlight reaching solar panels dips dramatically, causing a temporary drop in solar power generation. This can create a challenge for managing the electric grid, especially in areas heavily reliant on solar power. But there’s no need to start prepping for a power outage.
Grid operators, the people behind the scenes keeping our lights on, are prepared for the eclipse and strategize weeks in advance for events like this. They'll be ready to tap into other reliable sources of electricity, like natural gas or wind power, to make up for the temporary shortage in solar power. Battery storage will also have a role to play, helping to balance the grid by supplying power during the eclipse.
How states in the path are getting ready for the eclipse
In anticipation of the upcoming solar eclipse, grid operators stretching from the sun-drenched plains of Texas up to the rocky shores of Maine are bracing themselves for a temporary yet significant decrease in solar power generation.
Here's what states within the path are doing to get eclipse-ready:
- Coordinating with electricity providers along the path. They're sharing information, assessing potential impacts, and ensuring everyone's on the ready to maintain grid stability.
- Ramping up power plant production. This ensures natural gas and other reliable sources will be ready to take over when solar power dips.
- Solidifying conservation contingency plans. While conservation requests are not expected, energy providers are prepared to schedule and deploy additional generation and regulation resources as necessary to account for possible shifts in load.
The bottom line? Grid operators in the eclipse's path, are taking proactive steps to ensure a smooth flow of electricity during this exciting celestial event. It's a testament to the resilience and adaptability of our electric grid and the people who keep it running. So, sit back, relax, and enjoy the eclipse — the lights will stay on.
