Strategic Partnerships
High. Partnering with WEC Energy Group subsidiaries allows MGE to purchase cost-effective fractional ownership shares (typically 10%) in large-scale solar, wind, and battery storage projects.
Terms: MGE owns fractional capacities (e.g., 35 MW solar, 5 MW battery, and 18 MW wind from four approved projects in late 2025; and 9.8 MW from Good Oak / Gristmill in early 2026) to share capital costs and risks.
