Robert W. Scherer

Georgia Power plan confirms move from coal to renewables | Georgia Public Broadcasting

The Robert W. Scherer Power Plant, also known as Plant Scherer is a coal-fired power plant located in Juliette, Georgia. The plant comprises four generating units, each capable of producing 930 megawatts for a total installed capacity of 3720MW.

The first of the four units was brought online in 1982 while the additional units were brought online in 1984, 1987, and 1989. Georgia Power Co. the owner and operator of the power plant has plans to decommission units 3 and 4 in 2024 and 2022 respectively.

The company said it isn’t sure whether it will close units 1 and 2 as those units, largely owned by others, are economically “challenged” and it would prepare to close them by 2028 while looking for options to keep them open.

W. A. Parish

WA Parish Generating Station - Wikipedia

Made up of two four-unit plants, one of which is a natural gas unit while the others are coal units, W.A. Parish Generating Station is a dual-fired power plant located near Thompsons in Texas.

The power plant, with a total installed capacity of 3,653 MW, entered into commercial operation in 1977 but it is however likely to be shut down following complaints that it is polluting the air and contributing to approximately 178 premature deaths each year.

It is also performing poorly in terms of electricity generation. During the 2021 Texas power crisis, it was reported to have experienced up to a 664 MW loss in generation capacity, including an 80 MW decrease in capacity early in the crisis that contributed to the need for rolling blackouts.

Turkey Point Nuclear Generating Station

Turkey Point Power Plant Facing Major Lawsuit | Gallardo Blog

Located on Biscayne Bay approximately 24 miles south of Miami and just east of the Homestead area, Turkey Point Nuclear Generating Station is a nuclear and gas-fired power plant with an installed capacity of 3562MW.

The power plant has a total of five power generation units. However, the first two (Units 1 and 2), which are fuel oil/natural gas/used oil/propane-fired generation units with a 404-megawatt capacity each, are retired.

The rest, two 802 MWe Westinghouse pressurized water reactors (Units 3 and 4), and a 1,150 MW combined-cycle gas-fired Unit 5 remain operational until 2052.

There are also plans for the construction of two 1,117-MWe Westinghouse AP1000 reactors (Units 6 and 7) the Combined Construction and Operating License (COL) application of which were authorized by the Nuclear Regulatory Commission (NRC) in April 2018.

Turkey Point Nuclear Generating Station serves the entire southern portion of Florida since 1967 when the first unit was commissioned followed by the rest in 1968, 1972, 1973, and 2007, in order.

Bowen Steam Power Plant

Georgia Power plans to finish shift from coal-fired plants by 2035 | Georgia Public Broadcasting

Plant Bowen or rather Bowen Steam Plant, is a 3499MW coal-fired power plant located just outside Euharlee, Georgia, approximately 14 km west-south-west from Cartersville.

It is made up of four units, with electricity generation capacities of 806, 789, 952, and 952 megawatts, respectively. The first unit began operation in 1971, and additional units were respectively brought online in 1972, 1974, and 1975.

In November 2021 it was announced that two of the four units at Plant Bowen would tentatively close by 2028 while the rest, with a combined capacity of 1,904 MW, would be operated until 2035.
