Photo taken from the air that shows a tall tower toward the left rising above a flat field. In front of the tower on the field is an oval-shaped area containing rows of flat mirrors that are approximately concentric to the tower. The mirrors are oriented horizontal to the ground, but when in operation, they will be oriented to focus the sun onto the top of the tower.

Planta Solar 10

This page provides information on Planta Solar 10, a concentrating solar power (CSP) project, with data organized by background, participants, and power plant configuration. Abengoa Solar's Planta Solar 10 is the first solar central-receiver system producing grid-connected electricity under a purely commercial approach. PS10's technologies—including glass-metal heliostats, pressurized-water thermal storage system, and saturated-steam receiver and turbine—were previously tested and qualified at the Plataforma Solar de Almería facility. This testing helped to avoid technological uncertainties and allowed the project to focus on scaling up, integrating subsystems, demonstrating dispatchability, and reducing O&M costs. The plant's thermal storage system has a 50-minute capacity at 50% load to handle cloud transients. The tower was designed to reduce visual impact—its relatively narrow body includes a large open space to give a lightweight sense.
