Philo Power Plant was a 510 megawatt (MW), coal power plant located in Philo in Muskingum County, Ohio. It was the first power plant in the United States to apply steam reheat and supercritical steam generator technologies for its turbines. The plant had six units and its operations were handled by Ohio Power, a forerunner of American Electric Power (AEP). It operated from 1924 until ceasing in 1975.
Construction of the Philo Power Plant began in 1922 with the plant designed by Sargent & Lundy. [1] [2] Philo began commercial generation with Unit 1 in 1924. [3] This unit initially had a nameplate capacity of 35 MW from General Electric's curtis turbine, but was raised to 40 MW after performing well on its test run. [2] The turbine had a maximum pressure of 600 psi (4,100 kPa) and temperature of about 725 °F (385 °C). It was the first unit in the country that utilized steam reheat. [3] Unit 1 was decommissioned and replaced by Unit 6 in 1957. [4] Unit 2 was completed in 1925 and also had a nameplate capacity of 40 MW. [2] [5] The total cost of both units was $10 million. [6] Unit 3 was completed in 1929 with a nameplate capacity of 165 MW. [7] [8] The total cost to construct Unit 3 was $17 million. [8] Units 4 and 5 were completed in 1941 and 1942 respectively and each had a nameplate capacity of 85 MW. [4]
Philo Unit 6 was the nation's first commercial supercritical steam generator. The unit began commercial generation in 1957 with nameplate capacity of 120 MW. [9] Its steam generator, designed and built by Babcock & Wilcox, had a maximum pressure of 4,500 psi (31,000 kPa) and an operating temperature of about 1,150 °F (621 °C). [9] [10] Its steam turbine was designed and built by General Electric that made 3,600 rpm. [10] The unit was able to demonstrate operations at ultrasupercritical levels, but due to the lack of metals able to tolerate the extreme temperatures, the levels were unsustainable. [11] To support the new unit, a 183 ft (56 m) smokestack was erected. [9] The total cost to construct Philo Unit 6 was approximately $19.5 million. [12]
When Philo began operations, the plant maintained a thermal efficiency of 24% consuming 14,000 BTU. Coal used by the plant came by either rail or river barge. [2] Most of the coal burned at Philo was mined within the State of Ohio with some coal coming from West Virginia. [4] Water was sourced from the Muskingum River with its intake being above a dam and was discharged below the dam. [2] At the time of its deactivation, 203 employees worked at the plant. [3]
Philo was deactivated on May 31, 1975. The company cited declining electricity demand during the 1973–75 recession and the facility being surpassed by newer, more efficient power plants. [3] The plant went on standby following deactivation with a single unit used to regulate voltage. Ohio Power remained optimistic that Philo would be reactivated. [13] The plant was eventually demolished in 1983. [14] After the Philo Power Plant was demolished, the rotors from the turbine from Unit 6 were utilized in a sculpture created by George Greenamyer. [15] The sculpture was unveiled in October 1983 as a part of a landscape design project for the newly built AEP Building located in Columbus, Ohio. [15] [16]
Philo is a village in Muskingum County, Ohio, United States, along the Muskingum River. The population was 733 at the 2010 census.
American Electric Power (AEP), is a major investor-owned electric utility in the United States, delivering electricity to more than five million customers in 11 states.
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind or the sun. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production.
The Mountaineer Power Plant is a major coal-fired power plant outside New Haven, West Virginia, USA. Owned by American Electric Power (AEP), it has one of the tallest chimneys in the world at 336 metres (1,102 ft). This chimney was built as part of the plant in 1980 and is not in use now. It has been replaced by a slightly shorter and wider chimney for the electrostatic precipitator and scrubber units.
Hub Power Company Limited, colloquially known as HUBCO, is the first and largest Pakistani Independent Power Producer (IPP) with a combined installed power generation capacity of 2920 MW.
The William H. Zimmer Power Station, located near Moscow, Ohio, is a 1.35-gigawatt coal power plant. Planned by Cincinnati Gas and Electric (CG&E), with Columbus & Southern Ohio Electric and Dayton Power & Light (DP&L) as its partners, it was originally intended to be a nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. The plant began operations in 1991. Today, the plant is owned and operated by Vistra Energy.
Rockport Generating Station is a coal-fired power plant, located along the Ohio River in Ohio Township, Spencer County, Indiana, in the United States, near Rockport. The power plant is located along U.S. Route 231, approximately one mile north of the William H. Natcher Bridge, spanning the Ohio River. It is operated by Indiana Michigan Power, a subsidiary of American Electric Power.
J. Robert Welsh Power Plant is a 1-gigawatt, coal power plant located east of Pittsburg, Texas in Titus County, Texas. It is operated by SWEPCO, a subsidiary of AEP. The plant is named after J. Robert Welsh, a former President and Board Chairman of SWEPCO.
The AEP Building is a 456 ft-tall (139 m) skyscraper in Downtown Columbus, Ohio. It was completed in 1983 and has 31 floors. Abramovitz, Harris & Kingsland designed the building following a modernist architectural style. The AEP Building is the 8th tallest building in Columbus. It has served as the headquarters of the American Electric Power (AEP) since the company relocated from New York City in 1983.
John E. Amos Power Plant is a three-unit coal-fired power plant owned and operated by Appalachian Power, a subsidiary of American Electric Power (AEP). With a nameplate rating of 2,933 MW, it is the largest generating plant in the AEP system. It was named after John E. Amos, a prominent state senator, Democratic National Committee member from West Virginia, and member of the AEP board of directors.
Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely. There are many upsides to repowering.
