Question: Which company started life running streetcars in the early 1900's and now operates hydroelectric dams?

full_context: Document 1: Geary Street, Park and Ocean Railway: The Geary Street, Park and Ocean Railway was one of the first cable car operators in San Francisco. Operation commenced in 1880, and the route soon proved quite popular. The line was purchased by the Market Street Railway in 1887. In 1912, the city declined to renew the franchise and instead took over operation of the Geary Street railway. The line was converted into an electric streetcar line, forming the first element of the San Francisco Municipal Railway (Muni) that was to come to be synonymous with transit in that city. Muni replaced the street cars with motor coaches in 1956. Today, the bus routes that serve the Geary corridor are the most heavily used in San Francisco.

The dam wall of 325 m3 is 43 m high and 528 m in length. At 100% capacity, the dam wall holds back approximately 85500 ML and creates the impounded reservoir of Lake Yarrunga that has a surface area of 831 ha , drawn from a catchment area of 5750 km2 . The spillway has a discharge capacity of 27600 m3/s .
Document 3: Georgia-Pacific: Georgia-Pacific LLC is an American pulp and paper company based in Atlanta, Georgia, and is one of the world's leading manufacturers and distributors of tissue, pulp, paper, toilet and paper towel dispensers, packaging, building products and related chemicals. As of Fall 2010, the company employed more than 40,000 people at more than 300 locations in North America, South America and Europe. It is an independently operated and managed company of Koch Industries.
Document 4: Hiwassee Dam: Hiwassee Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina. It is one of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s to bring flood control and electricity to the region. The dam impounds the Hiwassee Lake of 6000 acre , and its tailwaters are part of Apalachia Lake. At 307 ft , Hiwassee Dam is the third highest dam in the TVA system, behind only Fontana and Watauga.
Document 5: Lake Keowee: Lake Keowee is a man–made reservoir in the United States in the state of South Carolina. It was created to serve the needs of a power utility (Duke Energy) as well as public recreational purposes. It is approximately 26 mi long, 3 mi wide, with an average depth of 54 ft , and a shoreline measured at 300 mi in total, and is approximately 800 ft above sea level. It began in 1971 as a massive demolition and building project, including the construction of two large dams––Keowee Dam and Little River Dam––and covered 18372 acre of the state. The lake collects or "impounds" waters from the Keowee River and the Little River and others, and the outflows below the respective dams join to form the Seneca River which flows into the larger Savannah River. Lake water helps to cool Duke Energy's three nuclear reactors located at the Oconee Nuclear Generating Station. In addition, the force of falling water through gravity helps generate hydroelectric power. The Keowee Hydro Station generates 158 megawatts from the lake's outflows. In addition, Lake Keowee has been touted as a recreational destination for fishing, boating, swimming, sailing, kayaking and other watersports, and the lake has been described as having pure and clean water. The name "Keowee" (ᎨᎣᏫ) is a Cherokee name roughly translated as "place of the mullberries." The former Keowee River, which was inundated by Lake Keowee, had been part of the Cherokee Lower Towns region, and Keowee Town had been located on the bank of the Keowee River.
Document 6: Georgia and Alabama Railroad: The original Georgia and Alabama Railroad was based in Rome, GA, incorporated in 1853, and started initial rail construction in 1857. In August 1866, the G&A officially consolidated with the Dalton and Jacksonville Railroad and the Alabama and Tennessee River Railroad Company with the intent to create a consolidated rail system from Selma, AL to Dalton, GA. The consolidated corporation was to do business under the name of the latter, but it officially took the name Selma, Rome and Dalton Railroad Company in December of that same year. Still, in some cases, business continued under the name of Georgia and Alabama Railroad. For instance, in May 1868, a contract was executed to the Georgia and Alabama Railroad, leasing 100 African American convicts in the state of Georgia to work for the railroad company without pay.
Document 7: Tugaloo: Tugaloo was a Cherokee town on the Tugaloo River, at the mouth of Toccoa Creek, near present-day Toccoa, Georgia and Travelers Rest in Stephens County, Georgia.

Document 9: Kansas City Power and Light Company: Kansas City Power and Light Company is an electric utility company serving the Kansas City metropolitan area. It is a wholly owned subsidiary of Great Plains Energy Incorporated of which it is the biggest component. The company traces its roots to November 1881 when Joseph S. Chick obtained the exclusive rights to use the Thompson-Houston arc lighting system in the counties of Jackson, Missouri, and Wyandotte, Kansas, for $4,000. The following month, the initial franchise to establish an electric works in the City of Kansas, Mo., was granted to Lysander R. Moore and later assigned to "Kawsmouth Electric Light Company". Construction was begun in February 1882 on a power plant on a tract of land at the southeast corner of 8th and Santa Fe Streets in the West Bottoms. Kawsmouth Electric Light Company built quickly and, on Saturday night, May 13, 1882, brought electric illumination to the first 13 customers on the west side of Main Street in the downtown district. In 1885 the company reincorporated as "Kansas City Electric Light Company".

Document 12: Watauga Dam: Watauga Dam is a hydroelectric and flood control dam on the Watauga River in Carter County, in the U.S. state of Tennessee. It is owned and operated by the Tennessee Valley Authority, which built the dam in the 1940s as part of efforts to control flooding in the Tennessee River watershed. At 318 ft , Watauga is the second-highest dam in the TVA river and reservoir system (behind only Fontana), and at the time of its completion was one of the highest earth-and-rock dams in the United States. The dam impounds the TVA Watauga Reservoir of 6430 acre , and its tailwaters feed into Wilbur Lake. The Appalachian Trail crosses the top of Watauga Dam.
Document 13: Chatuge Dam: Chatuge Dam is a flood control and hydroelectric dam on the Hiwassee River in Clay County, in the U.S. state of North Carolina. The dam is the uppermost of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s for flood storage and to provide flow regulation at Hiwassee Dam further downstream. The dam impounds the 7000 acre Chatuge Lake, which straddles the North Carolina-Georgia state line. While originally built solely for flood storage, a generator installed at Chatuge in the 1950s gives the dam a small hydroelectric output.
Document 14: Atlanta and Richmond Air-Line Railway: Organized in 1870, the Atlanta and Richmond Air–Line Railway combined the Georgia Air Line Railroad and the Air Line Railroad in South Carolina under president Algernon S.
