Torresol Energy

Torresol Energy

The company Torresol Energy was founded in 2008 with a view to promote the technological development, construction, use and maintenance of large concentrated solar power (CSP) plants throughout the world. After its first development phase, the company’s activities involved three SPVs (GEMASOLAR, ARCOSOL and TERMESOL), which own other operative plants in Spain, Gemasolar, Valle 1 and Valle 2, and an operating company, Torresol Energy Operation & Maintenance (TOM), which is responsible for running the aforementioned facilities under the principles of maximum safety, efficiency and environmental respect.

To do this, the company works with new technologies for each new project, with a view to turn this energy into a viable, economically competitive and environmentally-friendly alternative with respect to traditional energies.

The objective of Torresol Energy is to achieve excellence in operating and maintaining its solar thermal power plants, thus contributing to the development and improvements of competitiveness in this technology.

  • Gemasolar, the world’s first plant that works on a commercial scale with a central tower receiver and a thermal storage system, located in Fuentes de Andalucía (Seville), running at a power of 17 MWe
  • Valle 1 and Valle 2, two plants that run at 50 MW each, with SENERtrough® parabolic trough collectors, located in San José del Valle (Cádiz).

All of Torresol Energy’s plants are equipped with heat storage, which allows them to deliver electricity even during prolonged absences of radiation (nights), giving their product (kWh from a renewable origin) a unique quality in the sector, in guaranteeing programmable and manageable energy.

The technological advances of Torresol Energy’s innovative plants have been developed by SENER, the leading company in the solar thermoelectric energy sector, both in terms of the number of projects in its portfolio and for its cutting edge technological solutions.

Investment, promotion, maintenance, operation

To develop solar power globally through investment in efficient and profitable solar concentration plants and thus pioneer new thermosolar technologies to reduce the cost of future plants.

Operational excellence

To become a global company leading the use of reliable solar power and which contributes to the protection of the environment for future generations.

Pioneeris in new technologies

To invest in innovation to become pioneers in new technologies that will render it possible to progressively reduce investment in thermosolar plants.

Torresol Energy began to take shape in 2007, when SENER decided to promote its own thermosolar plants all over the world and invest in them in the long term. To address this important challenge it identified MASDAR as the ideal partner. Both companies shared the same vision on the development of thermosolar power.

Thus, in 2008 Torresol Energy was incorporated, 60%-owned by the SENER Grupo de Ingeniería and 40% by MASDAR, the alternative energies company of Abu Dhabi.

In 2008 work got under way on the building of the Gemasolar plant in the province of Seville (Spain). In spring 2009, work began on the construction of a further two plants, Valle 1 and Valle 2, equipped with cylindrical-parabolic collector technology (CPC) and located in the province of Cadiz (Spain).

For the portfolio of projects currently in progress, entailing an investment amounting to almost one billion euros, Torresol has closed long-term “Project Finance” funding lines, which has enabled it to address these projects thanks to the continuous support of  international and Spanish financial organizations.
