question: Which company started life running streetcars in the early 1900's and now operates hydroelectric dams?
answer: Georgia Power
context: Title: Conowingo Dam
  Passage: The Conowingo Dam (also Conowingo Hydroelectric Plant, Conowingo Hydroelectric Station) is a large hydroelectric dam in the lower Susquehanna River near the town of Conowingo, Maryland.  The medium-height, masonry gravity dam is one of the largest non-federal hydroelectric dams in the U.S.
  Title: History of the Inga dams
  Passage: This is a history of the Inga dams, chronicling the various studies, plans, and projects that have aimed to harness the energy of the Congo River at the site of the Inga Falls, located north of Matadi in the Democratic Republic of the Congo (DRC).  The immense potential of the Inga Falls was recognized in the early 1900s, though the first major hydroelectric project, initiated by the Belgians, did not come until the late 1950s.  Two dams were built at the site during the rule of President Mobutu Sese Seko: Inga I was commissioned in 1972 and Inga II in 1982.  Since then proposals have been put forth for an Inga III as well as a Grand Inga, which if built, would be the largest hydroelectric facility in the world.
  Title: List of dams and reservoirs in Sri Lanka
  Passage: The following page lists most dams in Sri Lanka.  Most of these dams are governed by the Mahaweli Authority, while the Ceylon Electricity Board operates dams used for hydroelectric power generation.  Hydroelectric dams, including small hydros accounts for nearly half of the installed power capacity of Sri Lanka.
  Title: La Tuque Generating Station
  Passage: The La Tuque Generating Station is an hydroelectric power plant, located on the Saint-Maurice River, at the height of the city of La Tuque, in the province of Quebec, in Canada.  This power plant is the property's of Hydro-Québec.  It is 6th of 11 hydroelectric dams on the river from the mouth.
  Title: Lake Tugalo
  Passage: Lake Tugalo is a 597 acre reservoir with 18 mi of shoreline located in the northeastern Georgia in Habersham and Rabun counties, but also lies partially in Oconee County, South Carolina.  It is the fifth lake in a six-lake series created by hydroelectric dams operated by Georgia Power that follows the original course of the Tallulah River.  The series starts upstream on the Tallulah River with Lake Burton followed by Lake Seed, Lake Rabun, Lake Tallulah Falls and Lake Tugalo, ending with Lake Yonah.  The western arm of Lake Tugalo is filled by the Tallulah River and the eastern arm is filled by the Chattooga River.  Georgia Power considers the lake full at a surface elevation of 891.5 ft .
  Title: Safe Harbor Dam
  Passage: The Safe Harbor Dam (also Safe Harbor Hydroelectric Station) is a concrete gravity dam on the lower Susquehanna River with an associated hydroelectric power station.  It is the most northerly and last of three Great Depression-era public electrification projects' hydroelectric dams and was constructed between 1 April 1930 and 7 December 1931.  It created a long and relatively shallow lake along the upper stretch of the Conejohela Valley known as Lake Clarke.  The creation of the lake shrank the upper Conejohela Flats in size.
  Title: Georgia Power
  Passage: Georgia Power is an electric utility headquartered in Atlanta, Georgia, United States.  It was established as the Georgia Railway and Power Company and began operations in 1902 running streetcars in Atlanta as a successor to the Atlanta Consolidated Street Railway Company.
  Title: Iron Gates
  Passage: The Iron Gates (Romanian: "Porțile de Fier" , Serbian: "Đerdapska klisura" , German: "Eisernes Tor" ) is a gorge on the Danube River.  It forms part of the boundary between Serbia and Romania.  In the broad sense it encompasses a route of 134 km ; in the narrow sense it only encompasses the last barrier on this route, just beyond the Romanian city of Orșova, that contains two hydroelectric dams, with two power stations, Iron Gate I Hydroelectric Power Station and Iron Gate II Hydroelectric Power Station.
  Title: Tapajós hydroelectric complex
  Passage: The Tapajós hydroelectric complex (Portuguese: "Complexo Hidrelétrico de Tapajós" ) is a proposed complex of hydroelectric dams on the Tapajós and Jamanxim rivers in the state of Pará, Brazil.  The Tapajós dams would contain locks, thus converting the river into a navigable waterway.  A "platform" model is proposed under which all people and material would be moved by river or by helicopter, avoiding the need to build access roads and the consequent inflow of settlers and environmental damage.  However, there have been protests against flooding of indigenous territory by the dams, and the largest dam seems unlikely to be approved.
  Title: Kukuan Dam
  Passage: Kukuan Dam () is a concrete thin arch dam on the Dajia River in Heping District, Taichung, Taiwan.  The dam serves for hydroelectric power generation and flood control, and is the third in a cascade of hydroelectric dams on the Dajia River, being located below the Techi and Qingshan dams and upstream from the Tienlun Dam.  The dam supplies water to a power station consisting of four 45 megawatt (MW) turbines for a total capacity of 180 MW, generating 507 million kilowatt hours per year.
