Invenergy: A Deep Dive into America’s Fast-Growing Renewable Energy Developer

As countries worldwide look to reduce carbon emissions to combat global warming, companies are looking to prove that renewable energy can be delivered cost-effectively and at scale. Invenergy has been at the forefront of the push to make renewable energy affordable and more commonplace. The result has been a fast-paced growth and the development of some of the country’s largest solar and wind projects. Here is an in-depth look at one of the major companies behind the growing renewable energy industry.

The history of Invenergy

Invenergy was founded in 2001 by a former engineer who had made a name for himself – and a fortune – developing power-plant technology. Michael Polsky worked as a power-plant engineer in the late 1970s when U.S. public policy changed to encourage private companies to develop power plants. Polsky saw an opportunity, and in 1985, he co-founded Indeck Energy Services. The company grew to more than $100 million in value and was recognized three times as one of the fastest-growing companies in the United States.

When a disagreement led Polsky to leave Indeck in 1995, he started another energy company, SkyGen Energy. SkyGen specialized in creating gas-powered generators capable of engaging and creating energy quickly to meet with spikes in electricity demand. Not wanting to take the company public, Polsky sold SkyGen in 2000 for a net profit of $650 million.

Ready for his next energy venture, Polsky founded Invenergy. His initial vision was to purchase power plants at discount prices from energy companies struggling to manage their debt. When the venture failed to gain traction, Polsky began looking for alternatives. Realizing that financing ventures wasn’t his strong suit, he returned to what he knew well: Energy development.

Looking to find a foothold in a growing energy niche, Invenergy undertook its first project – a wind farm in Tennessee. The project flopped when construction in the remote area cost more than anticipated, and the area wasn’t windy enough to generate significant energy. The $40 million project lost $6 million overall. But Polsky and the Invenergy team used the lessons learned to become a major player in green energy in North America, with additional projects in South America, Europe, and Asia.

Invenergy today

Today, Invenergy is the largest privately-held renewable energy company in North America. It is headquartered near Chicago, with regional offices in New York and Denver, Canada, Mexico, Colombia, El Salvador, Israel, Scotland, Poland, and Japan.

Invenergy generates 28,505 megawatts from 180 different projects in North America, South America, Europe, and Asia. In all, Invenergy’s wind, solar, and natural gas plants are capable of powering nearly 8.3 million homes. The company has created record-setting renewable energy facilities, including its Grand Ridge Energy Center, which is located southwest of Chicago. The facility is one of the world’s largest combined renewable energy facilities, with 140 wind turbines, 120 acres of solar panels, and a battery installation.

Invenergy’s holdings include:

• Wind farms – Invenergy has created more than 78 wind farms in the United States, Mexico, Scotland, Poland, Uruguay, and Japan. Invenergy harvests more wind energy than any other independent energy company in North America.

• Solar farms – Solar farms are a newer venture for Invenergy, though the company is still a top-10 generator of solar energy in the United States. Invenergy has solar installations in the United States, Canada, Mexico, Uruguay, and Japan. In addition to developing rural installations, Invenergy also has gained attention for redevelopment projects, such as transforming an old golf course in Long Island into a solar farm.

• Natural gas – Invenergy’s natural gas plants are focused on efficiency, with plants, on average, producing 50 percent less carbon dioxide than coal-fired power plants. The company runs 11 natural gas plants in the United States, Canada, and Mexico.

• Battery storage – With natural energy comes the need for energy storage that allows for the control of the flow of energy into the grid, despite the natural fluctuations in solar rays or wind velocity. Invenergy considers itself a leader in energy storage and has six battery storage facilities in the United States.

• Clean water – Recognizing the growing demand for clean water worldwide, Invenergy works with municipalities to meet water needs for local industry through the desalination process. Invenergy handles water projects from end-to-end, with development, financing, engineering, construction, distribution, and management.  

As the company is privately held, its exact value is unknown, but industry analysts estimate its worth at $10 billion. In addition to its energy facilities, Invenergy also has a venture capital wing, Energize Ventures. The V.C. fund is valued at $150 million and focuses on green technology, including companies that develop drones and laser technology to inspect wind turbines and another that develops electric vehicle charging stations.

Within the water industry, Invenergy notes that currently, 25 percent of the world’s population – or 1 billion people – suffers from a lack of clean water, and that number is expected to grow to 3.5 billion by 2025. In Texas alone, it is projected that the economy will see $91 billion in income losses by 2030. Increasing, Invenergy asserts, more people are gaining access to clean water through the types of desalination projects that Invenergy oversees.

The future of Invenergy

Invenergy is continuing to see rapid growth and development. It has future planned projects in the United States, Mexico, El Salvador, Japan, and Israel.

One of the most notable planned projects is a Texas-based solar installation called the Samson Solar Energy Center that would become the largest solar energy farm in the United States. Announced in November 2020, the project would generate 1.3 gigawatts of energy and would span three Texas counties. The project, which would occur in phases, would see energy entering the grid in 2022, with another phase opening in 2023.

The project already has seen purchase commitments from AT&T – the largest such purchase in the United States, of 500 megawatts – as well as from Honda, McDonald’s, Google, Home Depot, and several Texas cities.

The company also has planned a Kansas wind farm that would be the nation’s largest installation of wind turbines. The project would see 1,000 wind turbines installed across 100,000 acres of Kansas farmland.

As green energy shows itself to be more affordable than energy generated through fossil fuels, Invenergy’s leadership has stated that they are committed to illustrating how green energy can be delivered efficiently at scale. The company’s website notes that the wind-energy industry has grown by 1,784 percent since 2001, and wind energy is 60 percent cheaper to produce today than it was five years ago. Similarly, the cost to produce solar power has dropped by 70 percent in the last 10 years.
