Wind Generation Profile * Kitty Hawk NC Challenge: Moving Wind Benefit to coincide with Dominion’s Peak Load
Solar Generation Challenge: Moving Solar Peak to coincide with economic benefit (PJM LMP Peak)
Solar / Battery Peak ShiftingOptimize Batteries for Peak Benefit Challenge: Moving Solar Peak to coincide with economic benefit (PJM LMP Peak) • Charge battery during off-peak w Solar • Discharge battery during peak • Solar Economic Volume • ≈$30/day Solar only • ≈ $90/day Solar & Battery
Solar Firming/Intermediacy Purpose: To flatten out the solar production throughout the day due to cloud cover by allowing the batteries to fill gaps during short periods of solar production intermediacy. Fast acting relays and controls allows for solar firming
