**Killen Station** was a 618 megawatt ([MW](/source/Megawatt)) dual-fuel power generating facility located east of [Wrightsville, Ohio](/source/Wrightsville,_Adams_County,_Ohio) in [Adams County, Ohio](/source/Adams_County,_Ohio). The power plant had two units: one coal-fired and one oil-fired. At the time of its closure, it was operated by AES Ohio Generation, a subsidiary of the [AES Corporation](/source/AES_Corporation). The plant began operations in 1982 and ceased generation on May 31, 2018.

## History

Construction of Killen Station began in 1974 and commenced commercial generation in 1982 at a cost of $588 million.[1][2] The plant was named after Robert B. Killen, a former chairman of [Dayton Power & Light](/source/DPL_Inc.) (DP&L).[3] A second coal unit was planned, but was cancelled in 1980 after estimates for electric use in the next decade were revised showing demand stagnating.[4] Killen's coal unit was retrofitted with a [selective catalytic reduction](/source/Selective_catalytic_reduction) (SCR) system between 2003 and 2004 by [Black & Veatch](/source/Black_%26_Veatch). The SCR was installed to comply with the [Clean Air Act](/source/Clean_Air_Act_(United_States)#Clean_Air_Act_Amendments_of_1990)'s 1990 amendments and Ohio's State Implementation Plan (SIP).[5] [Flue-gas desulfurization](/source/Flue-gas_desulfurization) (FGD) equipment, designed by the [Chiyoda Corporation](/source/Chiyoda_Corporation), was installed at Killen in 2007 to reduce [sulfur dioxide](/source/Sulfur_dioxide) () emissions.[6] In August 2014, Duke Energy sold its stake in the coal unit to [Dynegy](/source/Dynegy).[7] Operations at Killen were transferred from DP&L to AES Ohio Generation in October 2017.[8]

### Closure

DP&L announced plans in March 2017 to close Killen Station along with its sister plant [J.M. Stuart Station](/source/J.M._Stuart_Station) due to economic and environmental challenges in an agreement with the [Sierra Club](/source/Sierra_Club) and several unnamed parties.[9] The commercial generation of Killen ceased on May 31, 2018.[10] In December 2019, DP&L sold the site to Kingfisher Development for remediation and redevelopment.[11]

## Incidents

A worker was killed in August 1984 after getting pinned in a coal chute.[12]

A worker died in June 1994 from hyperthermia after attempting to rescue workers stranded in the plant's 900 feet (270 m) smokestack.[13][14]

On December 9, 2020, contractors were working to prepare the site for demolition. At around 8:30 A.M. the primary building collapsed injuring several and trapping others. Three workers were rescued from the collapse. Three days later, one worker was found dead[15][16][17] and on January 8, 2021, thirty days after the collapse, the final worker's body was recovered.[18]

## Archaeological site

The lands owned by DP&L for Killen Station contain two archaeological sites that date back to the [Adena](/source/Adena_culture) and [Fort Ancient](/source/Fort_Ancient) cultures. To prevent the sites from being disturbed during construction of the power plant, the [Ohio Historical Society](/source/Ohio_Historical_Society) applied to the [Department of the Interior](/source/United_States_Department_of_the_Interior) to include Wamsley Village and an Adena [burial mound](/source/Burial_mound) on the [National Register of Historic Places](/source/National_Register_of_Historic_Places).[19] Both listings were added to the National Register in 1974.[20][21] Archeology was conducted at Wamsley Village and the mound. The archeologists discovered a number of artifacts and burials.[22] These sites remain preserved today.[19]
