Rocky Mountain Hydroelectric Plant
The Rocky Mountain Hydroelectric Plant is a pumped-storage power plant located northwest of Rome in the U.S. state of Georgia. It is named after Rocky Mountain on top of which the plant's upper reservoir is located. Construction on the plant began in 1977 and it was commissioned in 1995. After upgrades were completed in 2011, the plant has an installed capacity of . It is owned by both Oglethorpe Power and Georgia Power which have 75 percent and 25 percent stakes, respectively.
==Background==
After Georgia Power applied for a Federal Energy Regulatory Commission (FERC) license to operate the plant in 1972, they began to carry out design studies and plans for land acquisition. Construction on the project began in 1977 after the FERC license was granted. The initial phase included the tunnels, penstocks, roads and bridges. Construction was suspended in 1985 when the project was 20 percent complete. In 1987, Oglethorpe Power, who was in need of a pumped-storage plant, began negotiations with Georgia Power to complete the power plant. On 15 December 1988, the two power companies reached an agreement after Oglethorpe received a US$706.8 million loan guarantee. The agreement allowed Oglethorpe to operate the plant and have a 75 percent stake in ownership. Construction on the power plant restarted shortly after the agreement.〔(【引用サイトリンク】url=http://www.fundinguniverse.com/company-histories/OGLETHORPE-POWER-CORPORATION-company-History.html )〕 In 1995 the power plant was completed and the generators commissioned. The project cost $1 billion and it was dedicated on 9 October 1995. An upgrade of the power station was completed in 2011 which increased the installed generating capacity of each turbine-generator from to . This increased the installed capacity of the plant from to 1,095 MW. The power of the pumps was also increased as well. The upgrade may seem early for the young power plant but the turbines, pumps and inlet valves were purchased before construction was suspended and sat in storage.〔〔(【引用サイトリンク】url=http://www.mwhglobal.com/mwh-projects/rocky-mountain-pump-storage-hydropower-upgrade )〕〔(【引用サイトリンク】url=http://www.industcards.com/ps-usa.htm )〕
