Dynegy Inc., commonly known as Dynegy, was an electric company founded in 1984 as Natural Gas Clearinghouse, later adopting the Dynegy name in 1998. Headquartered in Houston, Texas, it was a publicly traded company on the NYSE (ticker DYN) until its acquisition by Vistra Corp. on April 9, 2018. Prior to the acquisition, Dynegy reported approximately 2,489 employees in 2017 and an annual revenue of $4.8 billion in the same year.
Dynegy primarily focused on electricity generation through its ownership and operation of fossil fuel-powered (natural gas and coal) power stations across various U.S. states. It provided wholesale power, capacity, and ancillary services to a range of clients including utilities, cooperatives, and municipalities. Additionally, the company offered retail electricity services with fixed-rate plans to residential and commercial customers in deregulated markets such as Illinois, Ohio, Pennsylvania, and Massachusetts. Historically, Dynegy was also involved in natural gas supply and energy trading but exited these businesses by 2005.
In terms of patent litigation, Dynegy Inc. has a posture consistent with an operating company defending its business. The company has been involved in 1 tracked case, appearing solely as a defendant. This indicates that Dynegy is not an entity primarily engaged in patent assertion.
The sole tracked case involving Dynegy Inc. is Midwest Energy Emissions Corp. et al. v. Arthur J. Gallagher & Co. et al., where Dynegy is listed as a defendant in the U.S. District Court for the District of Delaware, with the case initiated on July 17, 2019. This litigation occurred after Dynegy's acquisition by Vistra Corp. in 2018, which created a leading integrated power company with significant generation capacity across competitive U.S. power markets.
