The Extresol 1 Concentrating Solar Power (CSP) – Thermal Energy Storage System is a 50,000kW energy storage project located in Badajoz, Torre de Miguel Sesmero, Spain.
The thermal energy storage project uses molten salt as its storage technology. The project was commissioned in 2010.
The Extresol 1 Concentrating Solar Power (CSP) – Thermal Energy Storage System was developed by Cobra Gestion de Infraestructuras (Ggrupo Cobra).
The key application of the project is renewables energy time shift, renewables capacity firming.
Cobra Gestion de Infraestructuras (Ggrupo Cobra) has delivered the project.
Electricity generation of the plant is 158,000 MWh/yr (Expected/Planned). The type of storage is 2-tank indirect and the description is as follows: 28,500 tons of molten salt. 60% sodium nitrate, 40% potassium nitrate. 1,010 MWh. Tanks are 14m high and 36m in diameter.
All publicly-announced energy storage projects included in this analysis are drawn from GlobalData’s Power IC. The information regarding the projects are sourced through secondary information sources such as country specific power players, company news and reports, statistical organisations, regulatory body, government planning reports and their publications and is further validated through primary from various stakeholders such as power utility companies, consultants, energy associations of respective countries, government bodies and professionals from leading players in the power sector.
