The 30MW Puerto Errado 2 development, built by Novatec Solar for Tubo Sol PE2 – a development consortium led by Swiss utility Elektra Baselland, will generate some 50 million kWh of electricity each year, enough to power 12,000 households.

The PE2 “solar boiler” is made up of 28 rows of linear Fresnel reflectors, each approximately 950 meters long, with a total mirror surface of 302,000 sq metres.
