The Vepřek Solar Park is the second largest photovoltaic power plant in the Czech Republic and the 15th largest photovoltaic power plant in the world.
 It is found near Vepřek village, part of Nová Ves municipality, approx 30 km north from Prague.
Amonix, Inc. is a solar power system developer based in Seal Beach, California.
 The company manufactures concentrator photovoltaic (CPV) products designed for installation in sunny and dry climates.
 CPV products convert sunlight into electrical energy in the same way that conventional solar photovoltaic technology does, except that they use optics to focus the solar radiation before the light is absorbed by solar cells.
 According to a comparative study of energy production of solar technologies, CPV systems require no water for energy production and produce more energy per megawatt (MW) installed than traditional PV systems.
 Amonix has nearly 70 Megawatts(DC) of CPV solar power systems deployed globally, including Southwestern U.S. and Spain.
 In May 2012, the Alamosa Solar Generating project, owned and operated by Cogentrix Energy, began commercial operation.
 This is the largest CPV power plant in the world and is expected to produce enough clean renewable energy per year to power more than 6,500 homes and will avoid the emissions of over 43,000 metric tons of carbon dioxide per year.
 The Alamosa Solar Generating Project is supported by a power purchase agreement (PPA), which is a long-term agreement to sell the power it will generate.
 Under the project’s PPA, the Public Service Company of Colorado will buy the power generated by the solar facility for the next 20 years.
 In July 2012, Amonix set the world record for photovoltaic module efficiency at 33.5% (full regression analysis) under nominal operating conditions, verified by the National Renewable Energy Laboratory.
 In April 2013, Amonix broke the record set in July 2012, demonstrating photovoltaic module efficiency at 34.9% (full regression analysis) under normal concentrator standard operating conditions (CSOC), also verified by the National Renewable Energy Laboratory.
 In August 2013, Amonix announced it had achieved a 35.9% photovoltaic module efficiency rating under concentrator standard test conditions (CSTC) as calculated by NREL.
 In June, 2014, the assets of Amonix were acquired by Arzon Solar, LLC for the purpose of continued development of CPV technology and products.
Solar power in Nevada has been growing, due to a Renewable Portfolio Standard which requires 20% renewable energy by 2015, and 5% from solar power.
 Nevada, at the end of 2007, became home to then-largest photovoltaic power plant in the world, the 14.2 megawatt (peak) Nellis Solar Power Plant, which, by selling the renewable energy credits (RECs), was able to provide Nellis Air Force Base with electricity for only 2.2 cents/kWh, compared to the 9 cents they are paying Nevada Power.
 Since then many larger solar power stations have been built in Nevada, with more proposed.
Calasparra Photovoltaic Power Plant (Spanish: "Planta solar fotovoltaico Calasparra" ) is a photovoltaic power station in Calasparra, Murcia in Spain.
 The project consists of different production units.

Alamosa photovoltaic power plant, is an 8.22 MWp photovoltaic power plant located in San Luis Valley, Colorado, USA.
 The power plant was developed by SunEdison, sells all output to Xcel Energy, and was completed in December 2007.
Beneixama photovoltaic power plant is a 20 MW photovoltaic power plant located in Beneixama, Spain.
 The plant consists of approximately 100,000 solar panels, encompassing an area of approximately 500,000 m.
 The panels are City Solar PQ 200 modules made of polycrystalline silicon solar cells.
The Olmedilla Photovoltaic Park is a 60-megawatt (MW) photovoltaic power plant, located in Olmedilla de Alarcón, Spain.
 When completed in July 2008, it was the world's largest power plant using photovoltaic technology.
Fibrominn, located in Benson, Minnesota, is the first power plant in the United States designed to burn poultry litter as its main source of fuel.
 It is producing 55 megawatts of electric power and burning turkey manure combined with wood chips.
 All of the energy is purchased by Xcel Energy.
 The plant was developed by Fibrowatt LLC, part of the Homeland Renewable Energy Group, which was set up by the management team which built the world's first three poultry-litter-fueled power plants (in the UK).
 Construction began in 2005 and the plant began operating in 2007, making it the largest biomass power plant in the United States .
 Grand opening ceremonies were held October 12–13, 2007.
 The plant is now owned by ContourGlobal, LP.

Question: Alamosa photovoltaic power plant developed by SunEdison, sells all output to Xcel Energy, a utility holding company based in what state? 
Answer: Minnesota
