For decades, the U.S. electric grid operated on a predictable rhythm. Coal and nuclear ran 24/7. Natural gas and hydro flexed around them. But by 2015, solar had grown 30x since 2010. On spring afternoons in California, renewables were meeting nearly 40% of demand. Then, between 4 PM and 7 PM, a strange thing happened. As solar faded and families came home to cook dinner, grid operators had to ramp conventional power faster than any other time of day—a 13,000 MW climb in three hours. That’s like adding 10 large nuclear plants in the time it takes to watch a movie.
The QER’s first installment, released in April, focused on energy transmission, storage, and distribution. On paper, that sounds technical. In reality, it marked the first time a major U.S. energy policy document implicitly asked: What happens when the sun sets? quadrennial energy review 2015
The 2015 QER didn’t panic. It observed. And in doing so, it reoriented the conversation from How much energy do we have? to When do we have it, and can we move it in time? For decades, the U
Here’s a short, interesting piece written in the style of a thought-provoking editorial or feature sidebar for a Quadrennial Energy Review 2015 —focusing on a theme that was both urgent and underappreciated at the time. If you search for images from the 2015 Quadrennial Energy Review (QER), you’ll find charts. Bar graphs of generation capacity. Tables of pipeline miles. But one chart—perhaps the most important of the year—looked less like infrastructure and more like a waterfowl. The “Duck Curve,” popularized by California’s grid operator, was no longer a future warning. In 2015, it began to quack. Natural gas and hydro flexed around them
In energy, as in sports, some of the best moves happen off the ball. In 2015, the U.S. began learning to dance with the sun. And the duck? It’s still quacking. Louder every year. Quadrennial Energy Review 2015: Transforming the Nation’s Electricity System — Key takeaway: Flexibility is the new fuel.
