**Generac Holdings Inc.**, commonly referred to as **Generac** (derived from a combination of *generating* and [AC](/source/Alternating_current)), is an American manufacturer of [backup power](/source/Backup_power) [generation](/source/Generator) products for residential, light commercial, and industrial markets.[6] Generac's power systems range in output from 800 watts to 9 megawatts[7] and are available through independent dealers, retailers, and wholesalers.[6] Generac has headquarters in [Waukesha, Wisconsin](/source/Waukesha%2C_Wisconsin),[2][5] and manufacturing facilities in [Berlin](/source/Berlin%2C_Wisconsin), [Oshkosh](/source/Oshkosh%2C_Wisconsin), [Jefferson](/source/Jefferson%2C_Wisconsin), [Eagle](/source/Eagle%2C_Wisconsin), and [Whitewater](/source/Whitewater%2C_Wisconsin), all in Wisconsin.[7]

## History

Founded by Robert Kern in 1959, Generac produced portable generators for [Sears, Roebuck and Co.](/source/Sears%2C_Roebuck_and_Co.) under the [Craftsman](/source/Craftsman_(tools)) brand.

During the 1970s the company expanded its offerings in the portable and recreational vehicle markets, and in the 1980s it entered the commercial and industrial markets with backup power generation systems.[7]

By end of the 1980s, the company was manufacturing residential, commercial and industrial generators, and in 1989, Generac introduced the first gaseous-fueled automatic home [standby system](/source/Standby_generator).[7]

In 1992, Generac began private labeling generator sets for [Caterpillar, Inc.](/source/Caterpillar_Inc.) As the partnership grew between the two companies, they discussed a potential acquisition of Generac by Caterpillar, although a deal was never finalized. In June 1996, Caterpillar decided to terminate the private labeling agreement. Generac then sued Caterpillar under the Wisconsin Fair Dealership Law ("WFDL"), the [Sherman Antitrust Act](/source/Sherman_Antitrust_Act), the Wisconsin common law concerning restrictive covenants, and the Illinois Consumer Fraud and Deceptive Business Practices Act.[8] The federal district court, in two separate orders, disposed of the action in Caterpillar's favor. Generac then challenged the lower court's rulings in the [U.S. 7th Circuit Court of Appeals](/source/United_States_Court_of_Appeals_for_the_Seventh_Circuit), which ruled that Generac's claims were properly dismissed by the lower court.[9] Generac continued to supply some transfer switches to Caterpillar until 2002, when Caterpillar changed suppliers.

In 1998, Generac sold its portable products division to the Beacon group, a [private equity](/source/Private_equity) firm, who later sold it to [Briggs & Stratton](/source/Briggs_%26_Stratton). Upon expiration of a non-compete agreement related to the sale in 2007, Generac re-entered the portable generator market in 2008.[7]

In late 2006, Generac was purchased by [CCMP Capital](/source/CCMP_Capital) of New York.[7] In 2009 CCMP took a write-off, described as a non-cash [goodwill](/source/Goodwill_(accounting)) and trade name impairment charge, of $583.5 million against their purchase of Generac.[10] Aaron Jagdfeld was appointed president and chief executive officer in September, 2008 and is the current CEO.[7]

### Generac goes public

On February 11, 2010, Generac Holdings Inc. (NYSE: GNRC), parent company of Generac Power Systems, Inc., began trading on the [New York Stock Exchange](/source/New_York_Stock_Exchange) under the ticker symbol GNRC.[7] The initial public offering provided $224 million in net proceeds, which were used to pay down debt.[7]

## Recognition

Generac is a recipient of [Milwaukee Magazine](/source/Milwaukee_Magazine)’s “Best Places to Work” award for Southeastern Wisconsin.[11]

Generac's industrial sizing application, Power Design Pro, received silver in the 2010 *Plant Engineering* "Product of the Year" award.[12]

The company has also earned the [Good Housekeeping Seal](/source/Good_Housekeeping_Seal) for its Guardian Series home standby generators and several portable generators.[13]

Generac was honored with the 2014 Natural Gas Generator Company of the Year Award from Frost & Sullivan for its contribution to the North American natural gas generator set industry.[14]

## Products

Generac manufactures gasoline-fueled, diesel-fueled and bi-fuel engine-driven power generation equipment, modular paralleling systems, automatic transfer switches and small engines.[6] The company supplies products to the industrial, commercial, and portable generator markets through many different distributors.

In December 2009, Generac introduced Generac Industrial Power (a rebranding of its industrial products division) to include new engines, new enclosures, ergonomic changes and aesthetic changes. This included a partnership with [Fiat Powertrain Technologies](/source/Fiat_Powertrain_Technologies) to supply Generac with industrial diesel engines for use in industrial generators.[15]
