What They Do

Invenergy's core technology focus spans wind, solar, natural gas, combined heat and power generation, and energy storage, with services extending to operations and maintenance via its Invenergy Services division founded in 2005 (source: infrapppworld.com). The company develops, owns, operates, and provides third-party management for power generation and storage facilities, delivering solutions at scale including grid-integrated renewables (source: infrapppworld.com).

Competitively, Invenergy differentiates as North America's top private renewable developer through its end-to-end expertise from development to operations, led by Polsky's engineering background, enabling profitable scaling beyond early setbacks like the Tennessee wind farm (source: bcigem.com).

Projects & Track Record

Invenergy has a global portfolio of power generation and storage facilities, with notable completed projects including early wind developments that have led to some of the most successful U.S. wind and solar sites (source: bcigem.com). Ongoing major projects feature the Cardal Transmission Project in Salto, Uruguay, where subsidiary Tealov S.R.L. secured US$67 million in construction financing from IDB Invest and executed an operating lease with Uruguay's National Administration of Power Plants and Electrical Transmissions (source: infrapppworld.com). Key clients and partnerships include IDB Invest for Uruguay financing, Puerto Rico Public-Private Partnerships Authority (shortlisted consortia involvement), and third-party asset owners via Invenergy Services (source: infrapppworld.com).
