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). Target markets include North America and Europe, serving utilities, commercial customers, and governments through large-scale projects that supply clean power to grids; customer segments encompass energy buyers seeking long-term power purchase agreements and owners needing asset management (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). Geographic presence spans development and operations in the United States, Canada, Mexico, Uruguay, Scotland, Poland, Israel, and Japan, with expansion via regional offices supporting new markets (source: bcigem.com).

Recent Developments

In the last two years, Invenergy Services surpassed a major milestone in its managed portfolio, though specifics on capacity or value are not quantified in announcements, highlighting its growth in third-party power asset management globally (source: invenergy.com). Subsidiaries Tealov S.R.L. and Invenergy Transmission completed construction financing and operating leases for the US$67 million Cardal Transmission Project in Uruguay with IDB Invest (source: infrapppworld.com). The company participated in Puerto Rico PPP shortlisting for three projects among 13 consortia, indicating active bidding (source: infrapppworld.com). No major acquisitions, mergers, or funding rounds were reported in this period, but ongoing project financings like Cardal signal expansion; no specific awards or certifications from 2024-2025 are detailed (source: infrapppworld.com).

Working There

Invenergy offers roles across engineering (software development, infrastructure, power plant tech), product management and design, sales and marketing (business development, customer success), operations (finance, HR, administrative), and executive leadership, primarily at its Chicago headquarters housing these departments (source: salestools.io).
