The Itá Hydroelectric Power Plant is a dam and hydroelectric power plant on the Uruguay River near Itá on the border of Santa Catarina and Rio Grande do Sul, Brazil. The power station has a {{convert|1450|MW|adj=on}} capacity and is supplied with water by a concrete face rock-fill embankment dam. It is owned and operated by Tractebel Energia and produces the equivalent of 60% of the energy consumed in Santa Catarina.
Background
Construction on Itá originally began in 1980 but was halted in 1987 because of financial conditions. In 1995, construction recommenced after a consortium was formed and the dam was complete in 2000. Most of the 6,000 people that were in the town of Itá were relocated to a new area above the reservoir.{{cite web |title=Itá Hydroelectric Power Plant, Brazil |url=http://www.power-technology.com/projects/ita/|publisher=Power-Technology.com |accessdate=12 September 2010}}{{Unreliable source?|reason=domain on WP:BLACKLIST|date=June 2016}}
The {{convert|741|ha|adj=on}} Fritz Plaumann State Park was created in 2003 as environmental compensation for the dam.{{citation|language=pt|ref={{harvid|Parque Estadual Fritz Plaumann – Fatma}}|title=Parque Estadual Fritz Plaumann|publisher=Fatma|url=http://www.fatma.sc.gov.br/conteudo/parque-estadual-fritz-plaumann|accessdate=2016-12-14|archive-date=2019-02-12|archive-url=https://web.archive.org/web/20190212124631/http://fatma.sc.gov.br/conteudo/parque-estadual-fritz-plaumann|url-status=dead}}
Itá Dam
The Itá Dam is a {{Convert|880|m|adj=on}} long and {{Convert|125|m|adj=on}} high concrete face rock-fill embankment dam with a crest elevation of {{Convert|375.5|m}} above sea level. The dam's reservoir has a capacity of {{Convert|5100000000|m3|acre.ft|abbr=on}}, surface area of {{Convert|141|km2}} and catchment area of {{Convert|45800|km2}}. The dam supports two spillways, one of its right abutment with six floodgates and another on the ridge to the dam's west, just south of the power plant which has 4 floodgates. Each gate measures {{Convert|21.8|m}} wide and {{Convert|18|m}} tall and in total, both spillways have a maximum capacity of {{Convert|49940|m3/s}}. Also on the ridge is the power plant's intake and three axillary dikes to support the reservoir level. The power plant intake is {{Convert|84.5|m}} wide and contains five gates that allow water to enter the five penstocks that are {{Convert|8|m}} in diameter and average {{Convert|197|m}} in length.{{cite web |title=Technical Specs - HPP Itá - UHIT |url=http://www2.tractebelenergia.com.br/modules/system/viewPage.asp?P=907&VID=&SID=609569496659033&S=1&C=82 |publisher=Tractebel Energia |accessdate=12 September 2010 }}{{dead link|date=November 2017 |bot=InternetArchiveBot |fix-attempted=yes }}
Power plant
The above ground power station is {{Convert|172.5|m}} long and {{Convert|57|m}} wide and contains five {{convert|290|MW|adj=on}} generators powered by Francis turbines. The first generator was commissioned in July 2000 and four more later that year with the last generator being commissioned in March 2001.
