Abengoa Solar

Abengoa Solar developed as the solar-focused business of Abengoa and was formerly known as Solúcar Energía. It was organized around the development and delivery of large solar-energy facilities rather than consumer retail products. Its stated activities included designing projects, promoting them, arranging or attaining financing, constructing plants, and operating completed installations. The technological scope included photovoltaics, concentrated photovoltaics, and concentrated solar thermal power. The company’s strongest identity was connected with concentrated solar power. In this model, mirrors or related optical equipment concentrate solar radiation to create heat, which is then converted into electricity through a thermal power cycle. Some of the company’s projects also incorporated thermal storage, allowing generation to be extended beyond the period of peak sunshine. This combination of project development, engineering, plant construction, and operational know-how enabled Abengoa Solar to pursue utility-scale installations in Spain and overseas. One of the company’s most visible Spanish assets was the PS10 Solar Power Plant. The 11-megawatt facility uses solar power tower technology, in which a field of mirrors directs sunlight toward a central receiver. Reference material identifies PS10 as Europe’s first commercially operating concentrating solar power plant. Its public profile was strengthened by appearances in television programs, including the Sci Fi network’s “World’s Strangest” and the BBC’s “James May’s Big Ideas.” Abengoa Solar also expanded internationally. Its technology and project activities were associated with the Solana Generating Station in Arizona, United States, and the Xina Solar One project in South Africa. These projects illustrated the company’s focus on large solar-thermal infrastructure in regions with high solar irradiation and government or market support for renewable generation. Research and development formed another important part of the business. The reference material reports more than €42.4 million of research investment in 2011 and more than €150 million cumulatively from 2007. It also reports 115 patent applications covering concentrated solar power and photovoltaic technologies as of May 2012. The company sought to protect its technical advances through priority rights and industrial and intellectual-property protections. The later history of Abengoa Solar was shaped by financial stress at its parent group. Abengoa accumulated a substantial debt burden, affecting its financing capacity and the structure of its businesses. In January 2023, Abengoa Solar was sold to Rioglass Solar Holding. The available sources do not specify the purchase price, the complete list of transferred assets, or the exact legal and commercial status of the brand after the transaction. For that reason, the company’s current status remains unknown in this dossier, although ownership by Rioglass Solar Holding is recorded for the reported transaction.

Utility-scale solar project development, engineering, and concentrated solar power technology

• Solar power generation

  Photovoltaic power plants

  Abengoa Solar designed, promoted, financed, constructed, and operated utility-scale photovoltaic facilities. These projects converted sunlight directly into electricity through photovoltaic modules and formed one part of the company’s broader solar-generation portfolio.

• Solar power generation

  Concentrated photovoltaic systems

  The company’s stated technology scope included concentrated photovoltaics, which use optical systems to focus sunlight onto high-efficiency photovoltaic cells. The available reference confirms this activity as part of the business scope but does not identify a separate branded product line or commercial launch date.

• Concentrated solar power

  Concentrated solar thermal power systems

  These systems concentrate solar radiation to produce high-temperature heat, which is converted into electricity through a thermal cycle. Abengoa Solar’s work covered project design, development, construction, and operation, with particular visibility in large power-tower and other solar-thermal installations.

• Solar power tower

  PS10 Solar Power Plant

  PS10 is an 11-megawatt concentrating solar power tower plant in Spain associated with Abengoa Solar. A field of mirrors directs sunlight to a central receiver, producing heat for electricity generation. Reference material identifies it as Europe’s first commercially operating concentrating solar power plant.

• Solar thermal power project · 2013

  Solana Generating Station

  Solana is a utility-scale concentrating solar power station in Arizona, United States, associated with Abengoa Solar’s international project portfolio. The facility uses solar-thermal generation and includes thermal-storage capability, enabling electricity production to continue beyond periods of direct sunlight.

• Solar thermal power project

  Xina Solar One

  Xina Solar One is a concentrated solar power project in South Africa associated with Abengoa Solar. It represents the company’s participation in international solar-thermal infrastructure and the use of storage-related capabilities in utility-scale renewable generation.
