Lumina II Solar Project
Intersect Power · Scurry County · ERCOT
Lumina II is a co-located solar-and-storage plant in Scurry County, Texas. EIA's May 2026 inventory reports a 326.6 MW nameplate solar generator with 320 MW seasonal capability, dated January 2024, plus a 160 MW battery generator dated October 2025. Intersect Power identifies the battery as a 320 MWh, two-hour system using 86 Tesla Megapacks. Intersect's 828 MWp / 640 MWac Lumina announcement covers the broader Lumina solar project, while the $837 million financing covers three Texas battery projects; neither portfolio figure is assigned solely to Lumina II.
