The '''Andasol 1 solar power station''' is Europe’s first [[parabolic trough]] commercial power plant (50 MWe), located near [[Guadix]] in the [[province of Granada]], [[Spain]]. The Andasol 1 power plant went online in November 2008, and has a thermal storage system which absorbs part of the heat produced in the solar field during the day. This heat is then stored in a molten salt mixture of 60% sodium nitrate and 40% potassium nitrate. A turbine produces electricity using this heat during the night, or when the sky is overcast. This process almost doubles the number of operational hours at the solar thermal power plant per year.<ref>[http://www.renewableenergyworld.com/rea/news/story?id=54019&src=rss Andasol 1 Goes Into Operation]</ref> |

The Andasol 1 solar power station is Europe’s first parabolic trough commercial power plant (50 MWe), located near Guadix in the province of Granada, Spain. The Andasol 1 power plant went online in November 2008, and has a thermal storage system which absorbs part of the heat produced in the solar field during the day. This heat is then stored in a molten salt mixture of 60% sodium nitrate and 40% potassium nitrate. A turbine produces electricity using this heat during the night, or when the sky is overcast. This process almost doubles the number of operational hours at the solar thermal power plant per year.[1]

Andasol 1, developed by Solar Millennium AG, is the first parabolic trough power plant in Europe. The plant has a gross electricity output of around 180 GWh per power plant per year and a collector surface of 510, 000 square meters (equal to 70 soccer fields). Andasol 1 has an electricity output of 50 megawatts and operates with thermal storage. A full thermal reservoir can run the turbine for about 7.5 hours at full-load, in case it rains or after sunset. The heat reservoirs each comprise of two tanks measuring 14 m in height and 36 m in diameter and contain molten salt. Andasol 1 is able to supply environmentally-friendly solar electricity for up to 200,000 people.[2]
The commissioning of Andasol 2 will follow in spring 2009 and Andasol 3 is scheduled for February 2011. These are also 50 MW solar thermal power plants. The Andasol power plants are helping to meet summer peak electricity demand in the Spanish power grid primarily caused by air conditioning units. The electricity supplied from the Andasol plants is ideal for meeting the demand during the the day, particularly early afternoon, when the power demand reaches its peak and solar radiation as well as the power plant output are also at their peak.[2]
