📊 Macro Trend Analysis
Historically, negative pricing clusters heavily in the spring and deeply windy winter months (noticeably spiking in 2023 and 2024). The volume of cheap slots systematically accelerates during seasons with erratic high-pressure weather patterns, where intense renewable generation (abundant wind) overlaps with mild temperatures, keeping baseline heating and cooling demands low.

âš¡ The "Sunday Slump" Phenomenon
There is a drastic intensity shift clustering specifically on Saturdays and Sundays. Plunges happen reliably during midday slots (10:00 - 15:00) and deep overnight segments (01:00 - 05:00). These windows represent the exact collision of maximum renewable output (peak midday solar or nighttime offshore wind) meeting the massive structural drop-off in commercial and industrial power consumption during the weekend checkout.

📅 The Seasonal Weekend Skew
Sunday heavily dominates the cheap pricing distribution vertically across all twelve months. Interestingly, during high-solar high-heat summer months (like July and August), this "weekend effect" frequently bleeds backwards into Fridays and Mondays as large parts of the industrial grid throttle down, exacerbating the oversupply problem.

💡 Slot Volume vs Day Consistency
While the previous chart highlights sheer volume (how many total slots plunged), this chart reveals reliability. It strips away multi-slot wind-storms to show you how many actual distinct calendar days plunged globally. If a cell is intensely colored here, it means you can routinely bank on that specific weekday plunging in that month!
