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, Indiana.
 The power plant is located along U.S. Route 231 (segment known as the Abraham Lincoln Memorial Parkway), approximately one mile north of the William H. Natcher Bridge, spanning the Ohio River.
 It is operated by Indiana Michigan Power, a subsidy of American Electric Power.
The Ohio Valley Electric Corporation (OVEC) is a company jointly owned by several parent electrical utilities.
 It is headquartered in Piketon, Ohio.
 OVEC and its wholly owned subsidiary, Indiana-Kentucky Electrical Corporation (IKEC), own and operate two coal-fired electrical generating plants.
 They are the Kyger Creek Power Plant, located near Gallipolis, Ohio, and the Clifty Creek Power Plant near Madison, Indiana.
The Gibson Generating Station is a coal-burning power plant located at the northernmost end of Montgomery Township, Gibson County, Indiana, United States.
 It is close to the Wabash River, 1.5 miles southeast of Mount Carmel, Illinois, 2 miles south of the mouth of the Patoka River, and 4 miles south of the mouth of the White River.
 The closest Indiana communities are Owensville 7.5 miles to the southeast of the plant, and Princeton, 10.5 miles to the east.
 With a 2013 aggregate output capacity among its five units of 3,345 megawatts, it is the largest power plant run by Duke Energy, the third-largest coal power plant in the world, and the tenth-largest electrical plant in the United States, With the reduction of Nanticoke Generating Station, it became the largest coal power plant in North America by generated power late in 2012.
 Also on the grounds of the facility is a 3000 acre large man-made lake called Gibson Lake which is used as a cooling pond for the plant.
 Neighboring the plant is a Duke-owned, publicly accessible access point to the Wabash River near a small island that acts as a wildlife preserve.
 This is the nearest boat-ramp to Mount Carmel on the Indiana side of the river.
 Located immediately south of Gibson Lake, the plant's cooling pond, is the Cane Ridge National Wildlife Refuge, the newest unit of the Patoka River National Wildlife Refuge and Management Area.
 Opened in August 2006, this 26 acre area serves as a nesting ground for the least tern, a rare bird.
 Cane Ridge NWR is reportedly the easternmost nesting ground for the bird in the U.S.
 The Gibson Generating Station is connected to the power grid via five 345 kV and one 138 kV transmission lines to 79 Indiana counties including the Indianapolis area and a sixth 345 kV line running from GGS to Evansville and Henderson, owned by Vectren and Kenergy.
The Saint Clair Power Plant is a major coal- and oil-fired power plant owned by Detroit Edison, a subsidiary of DTE Energy.
 It is located in St. Clair County, Michigan, on the west bank of St. Clair River.
 The plant is across M-29 from the newer Belle River Power Plant in East China, Michigan.
 The first four units of St. Clair were built in 1953–1954.
 Since then, three more generating units have been added to the plant.
 The St. Clair Power Plant generates 1982 megawatts in total.
 It is Detroit Edison's second largest power producer.
 The power plant has a large impact on the local economy, employing about 300 workers.
The Beles Hydroelectric Power Plant, sometimes referred to as Beles II or Tana Beles, is a run-of-the-river hydroelectric power plant in Ethiopia near Lake Tana.
 The power plant receives water from the lake and after utilizing it to produce electricity, the water is then discharged into the Beles River.
 The plant has an installed capacity of 460 MW and it is the second largest power plant in the country.
 It is also expected to help provide water for the irrigation of 140000 ha .
 It was inaugurated in May 2010 and the last generator was operational in February 2012.
 Its construction was negatively perceived by downstream Egypt.
Tanner's Creek Generating Station (also spelled Tanners Creek) was a major, 1000-MWe coal-fired electrical power plant in Indiana.
 Located on the north bank of Ohio River, it was one of the two coal-fired power stations within 3 mi of Lawrenceburg, Indiana, near the tripoint of Indiana, Ohio, and Kentucky (the other plant being the Miami Fort Power Station in the neighboring Ohio).
 The former plant is situated directly across the Ohio river from Petersburg, Boone County, Kentucky.
 Tanner's Creek was one of the two Indiana coal power plants owned by Indiana Michigan Power, a subsidiary of American Electric Power (the other plant being Rockport Generating Station near Rockport, Indiana).
The McCarthy Power Plant, also known as the Mother Lode Coalition Mining Company Power House and the Mother Lode Plant, is a historic power plant building in the small community of McCarthy, Alaska, in the heart of Wrangell-St.
 Elias National Park and Preserve.
 It is a three-story wood frame structure with a clerestory roof, located on the banks of McCarthy Creek.
 It was built in 1917, after the arrival of the Copper River and Northwestern Railway in the area kicked of a building boom.
 The coal-fired power plant was built to provide electricity for the operation of a tramway and other facilities of the Kennecott mines.
 Most of the transmission lines and the tramway were destroyed by avalanches in 1919, and other changes made soon afterward made the power plant unnecessary, and its turbine was moved up to Kennecott.
General James M. Gavin Power Plant is a 2.6-gigawatt (2,600 MW) supercritical coal-fired power station in the village of Cheshire, Ohio, United States.
 It is owned by Lightstone Generation LLC, a 50–50 joint venture of The Blackstone Group LP and ArcLight Capital Partners.
 Gavin is the largest coal-fired power facility in Ohio, and one of the largest in the nation, capable of powering two million homes.
 In February 2017, the plant represented slightly more than 11 percent of the total electric generation capacity in Ohio.
The Eklutna Power Plant, also referred to as Old Eklutna Power Plant, is a historic hydroelectric power plant on the Eklutna River in Anchorage, Alaska.
 Located about 5 mi downstream of the more modern new Eklutna Power Plant, it was built in 1928-29 to provide electrical power to the growing city, and served as its primary power source until 1956.
 The facilities include two dams, a tunnel and penstock, and a powerhouse.
 The main dam, Eklutna Dam, located at the northwestern end of Eklutna Lake, was built in 1941 to replace a series of temporary structures built after an earthen dam failed before the plant began operation.
 The diversion dam, a concrete arch dam, is located 7 mi downstream from the lake, and provides facilities for diverting water into the tunnel.
 The tunnel is 1900 ft long, and is terminated in a penstock, a structure designed to raise the water pressure.
 The powerhouse is a concrete-and-steel structure completed in 1929.
Kyger Creek Power Plant is a 1-Gigawatt coal-fired power station at Cheshire, Ohio, USA operated by the Ohio Valley Electric Corporation.
 Launched into service in 1955, the plant is located just 2.5 km downstream along the Ohio River from a much larger, newer coal-fired Gavin Power Plant.
 It has one of the tallest chimneys in the world at 305 m , built in 1980.

Question:  Kyger Creek Power Plant is downstream along the Ohio River from a power plant capable of powering what?
Answer: two million homes
