Image of a bar graph (where bars extend from the top of the graph downwards. A a full bar signifies 100% conventional power generation and an empty bar signifies 100% renewable generation). The bar graph image is directly attached above of a line graph (where the line graph shows percent of renewable curtailments), the day of the "Major Blackout" is highlighted across the bar and line graphs show it is the point where the grid has started with more renewable curtailments, and more conventional generation that provides spinning inertia. Before the blackout, conventional generation (e.g. nuclear, hydro, CCGT) was allowed to fall as low as 7% at noon on April 23. Renewables were dominant, and curtailments were minimal (~3%). After the blackout, a clear pattern emerges: higher conventional generation (noon levels at 26–44%) and increased curtailment of renewables (averaging 12% vs. <5% before). This suggests a shift in strategy. The blackout exposed the limits of operating a grid with minimal inertia. The other piece of the puzzle? Protection systems. Many were likely configured for a high-inertia grid. Without adaptation, they triggered rapid disconnections, worsening the cascade.

Trofim Lysenko crouches in a field holding a stalk of wheat while two others look attentively, black and white photo. Text above the image reads: "Biologist Trofim Lysenko studying the growth of wheat: His wild ideas, rejected by virtually all besides Stalin and Mao, directly caused the death of more than 50 million people. He rejected evolution and genetics and thought he could teach cross to grow desired traits via the power of collectivism"
