What Invenergy does

Invenergy is a privately-held, Chicago-based developer, operator, and investor in clean energy and energy infrastructure, founded in 2001 by Michael Polsky. The company operates as North America's largest privately held independent power producer with 220+ projects totaling 38 GW of developed capacity and 25+ GW in reliable operation across four continents (North America, South America, Europe, and Asia). Its diversified multi-technology portfolio spans natural gas (6+ GW across 13 facilities), utility-scale solar (8+ GW across 59+ projects), land-based wind, energy storage, HVDC transmission (including the $11 billion Grain Belt Express), geothermal, and clean hydrogen production. The company also owns adjacent operating subsidiaries including Reactivate (landfill solar), Illuminate USA, and Energize Capital.

The company's core technology stack centers on utility-scale generation and transmission assets combined with operational integration through its Center of Excellence (Central Machine Shop, Parts and Distribution Warehouse, 24/7 Generation Control Center) and analytics capabilities. Recent technology innovations include the Sauk Valley Hydrogen Facility - the first U.S. clean hydrogen plant using PEM electrolyzer technology from Ohmium International powered by on-site solar - and a Flexible AI Factory initiative developed in partnership with Nvidia and Emerald AI that pairs data center infrastructure with colocated power generation and storage using Nvidia's DSX reference design and Emerald AI's Conductor grid orchestration platform.

Invenergy generates revenue through long-term power purchase agreements (PPAs) with utilities, municipalities, and industrial customers, plus merchant sales into wholesale markets. Distribution occurs via direct enterprise field sales across 17 regional offices, with dedicated channels for utilities, industrial/manufacturing customers, and AI data center operators. The transmission business (Grain Belt Express) operates as merchant transmission connecting buyers and sellers of electricity. The company has secured substantial financing including a $3 billion Blackstone equity investment (2022), $900 million Green Letter of Credit facility (2024), $2.5 billion Revolving Credit Facility (2025), and multiple project-level debt facilities. In April 2026, founder Michael Polsky transitioned to Executive Chairman with Jim Murphy appointed CEO, signaling continuity through a generational leadership change.
