Commissioned in early 2012, Novatec Solar Espana’s 30 MW Puerto Errado 2 Thermosolar Power Plant is the world’s first and largest utility-scale, grid-connected linear fresnel reflector solar CSP power plant.

The plant employs a dry-cooled Thermodyne SAS steam turbine for reduced water usage and incorporates a Ruth single-tank thermocline thermal storage system, utilizing hot water and saturated steam, for efficient steam buffering. The project is built on a 170 acre site and has (28) rows of LFR mirrors.

Linear fresnel reflector technology (LFR) has concentrating solar power’s best land-to-electricity ratio due to a compact design and the potential use of space below the support structures. LFR technology uses flat or slightly curved mirrors to focus sunlight on to a linear receiver to boil water, generating 270 C to 500 C high-pressure direct steam to power the steam turbine genset. The direct steam technology eliminates the need for costly heat transfer fluids and heat exchangers. With simplified plant design, lower capital investment, and lower operational costs, LFR systems are among the most economical solar SCP technologies.
