What Invenergy does in wind energy

Invenergy is a private energy company that develops, builds, and operates wind farms across North America. The company does not sell electricity directly to households — instead, it builds large wind installations and sells the power they generate to utilities, businesses, and grid operators under long-term contracts. Understanding how Invenergy operates helps explain how wind farms connect to the broader electricity system and who benefits from the power they produce.

Invenergy was founded in 2002 and is headquartered in Chicago. The company has built wind farms in multiple U.S. states and Canadian provinces. Unlike some wind developers that focus on a single region, Invenergy operates across different markets, which means the terms of its contracts, the turbine technology it uses, and the local permitting process vary by location.

Key Takeaways

  • Invenergy builds and operates wind farms but does not sell power to individual customers — it sells to utilities and grid operators under contracts that typically last 15 to 25 years.
  • The company operates wind farms in multiple U.S. states and Canada, with project sizes ranging from under 100 megawatts to over 300 megawatts.
  • Wind farms Invenergy develops go through state and local permitting processes that include environmental review, noise studies, and community input before construction begins.
  • Invenergy uses modern turbine technology, typically in the 2.5 to 4.5 megawatt range per turbine, though specific models vary by project location and wind resource.
  • Property owners near Invenergy wind farms may receive lease payments for hosting turbines or transmission lines on their land.

How Invenergy wind farms connect to the electricity grid

Invenergy wind farms generate electricity that flows into regional transmission systems managed by grid operators. The company signs power purchase agreements (PPAs) with utilities or large commercial customers that commit to buying the wind farm's output for a set price over many years. This contract structure allows Invenergy to finance construction and guarantees a revenue stream, while the buyer locks in a predictable electricity cost.

The electricity produced does not go to a single location — it enters the grid and is distributed to wherever demand exists on that regional network. A utility might use Invenergy wind power to meet state renewable energy requirements, or a large corporation might use it to meet its own sustainability goals. The grid operator balances supply and demand in real time, so the wind farm's output is one piece of a much larger system that includes other wind farms, solar installations, natural gas plants, and hydroelectric facilities.

Invenergy wind farm locations and project sizes

Invenergy operates wind farms across the central and western United States and in parts of Canada. Major project locations have included Texas, Oklahoma, Kansas, Colorado, Illinois, and Ontario. The company's portfolio includes both onshore wind farms (on land) and has explored offshore wind development, though most of its current operating capacity is onshore.

Project sizes vary significantly. Some Invenergy wind farms generate under 100 megawatts of capacity, while larger installations exceed 300 megawatts. A megawatt is a unit of power — a 100-megawatt wind farm can power roughly 25,000 to 30,000 homes under average wind conditions, though actual output depends on local wind patterns and seasonal variation. Invenergy typically operates multiple projects simultaneously at different stages of development, construction, and operation.

Permitting and environmental review for Invenergy projects

Before Invenergy builds a wind farm, it must obtain permits from state and local authorities. The process includes environmental impact assessments, which examine effects on wildlife (especially birds and bats), noise levels, shadow flicker (the flickering shadow cast by rotating blades), and viewshed impacts on nearby properties. Different states have different requirements — some require detailed wildlife studies, while others focus more on noise or visual impact.

Local governments typically hold public hearings where community members can comment on proposed projects. County zoning boards or planning commissions review setback requirements (the minimum distance turbines must be from property lines), height restrictions, and other local rules. Invenergy must demonstrate compliance with these local standards before construction can begin. The permitting timeline varies from one to three years depending on the state and the complexity of local review processes.

Turbine technology and capacity at Invenergy wind farms

Invenergy uses modern wind turbines that typically range from 2.5 to 4.5 megawatts per unit, depending on the project and when it was built. Newer projects tend to use larger turbines with taller towers, which can capture wind at higher altitudes where wind speeds are more consistent. The specific model and capacity depend on the wind resource at each site — a location with strong, steady winds might use larger turbines, while a site with moderate winds might use smaller ones.

Turbine specifications also reflect the age of the project. Wind turbine technology has improved steadily over the past two decades, so a wind farm built in 2010 will have different equipment than one built in 2020. Invenergy sometimes retrofits older projects with new turbines or upgrades to existing installations to improve performance. The company publishes project-specific details in environmental review documents filed with state agencies, which are usually available to the public.

Land leases and payments to property owners

Property owners in areas where Invenergy develops wind farms may lease their land for turbine placement or for transmission lines and access roads. Lease payments vary widely based on location, land quality, and local market conditions. Typical arrangements involve annual payments per turbine or per acre, with payments often increasing over the lease term. Some landowners receive lump-sum payments at the start of the lease, while others receive annual royalties based on the wind farm's output.

Lease terms are negotiated between Invenergy and individual landowners and are not public information. However, landowners considering a lease should understand that they retain ownership of the land, that the lease is typically long-term (often 20 to 30 years), and that the land cannot be used for other purposes during the lease period. Landowners should review lease terms carefully or consult a lawyer before signing, as these agreements are legally binding contracts with significant implications for land use.

Decommissioning and end-of-life wind farm management

Wind turbines have a typical operational lifespan of 20 to 25 years, though some operate longer with maintenance and upgrades. When Invenergy wind farms reach the end of their useful life, the company must decommission them — removing turbines, towers, and foundations, and restoring the land. State regulations increasingly require wind developers to post financial assurance (a bond or escrow account) before construction to may provide that decommissioning funds will be available.

Decommissioning costs vary by project size and location but typically range from $300,000 to $500,000 per turbine. Some states require detailed decommissioning plans to be filed before permits are issued. Invenergy may also choose to repowering a site — replacing old turbines with new, more efficient ones — rather than fully decommissioning. This decision depends on the site's wind resource, the cost of new equipment, and the market for electricity at that location.

Frequently Asked Questions

Can I get electricity directly from an Invenergy wind farm?

No. Invenergy sells power to utilities and large commercial customers under contracts, not to individual households. Your local utility may purchase some of its power from Invenergy wind farms, but you would not know which specific projects supply your home. You pay your utility bill as usual, and the utility handles all the purchasing and distribution.

How much does an Invenergy wind farm cost to build?

Wind farm construction costs vary widely based on size, location, and turbine technology. A rough estimate is $1.2 to $1.6 million per megawatt of capacity, meaning a 100-megawatt project might cost $120 to $160 million. Invenergy finances these projects through a combination of equity investment, debt, and sometimes tax credits or other incentives. Specific project costs are not always public unless disclosed in regulatory filings.

Do Invenergy wind farms create jobs?

Yes, both during construction and operation. Construction typically employs hundreds of workers for one to two years. Permanent operations jobs are fewer — a large wind farm might employ 10 to 20 full-time technicians and support staff for maintenance and monitoring. Local economic benefits also include property tax payments and spending by construction workers in nearby communities.

What happens if an Invenergy wind farm is built near my home?

Local zoning rules determine the minimum distance (setback) between turbines and property lines, which varies by state and county but is often 1.5 times the turbine height or more. You may experience noise, though modern turbines are quieter than older models and typically produce 35 to 45 decibels at a distance of 300 feet. Shadow flicker and visual impact are also considerations. Review your local zoning code and any environmental review documents filed with your county to understand specific impacts.

Can I invest in Invenergy wind farms?

Invenergy is a privately held company, so you cannot buy stock in it directly. However, some of its wind farms are financed through project-level investments or partnerships that may be available to institutional investors or high-net-worth individuals. Invenergy also works with financial institutions that structure renewable energy investments. If you are interested in renewable energy investments, consult a financial advisor about available options in your area.
