PROJECT SUMMARY

In September 2011, the Department of Energy issued a $90.6 million loan guarantee to finance Alamosa, a 29.3-MW high concentration photovoltaic (HCPV) solar generation project. It is one of the first utility-scale HCPV projects in the U.S. and the largest HCPV generation facility in the world. The project started commercial operations in April 2012.

TECHNOLOGY INNOVATION

Alamosa uses innovative HCPV systems, consisting of concentrating optics and multi-junction solar cell panels that are controlled by a dual-axis tracking system. The tracking system rotates and tilts the cells throughout the day so the surface of the solar panel maintains an optimal angle with respect to the sun. The multi-junction solar cells are nearly 40% efficient – about double the efficiency of more traditional PV panels used in areas with high amounts of direct sunlight.

ECONOMIC IMPACT

Alamosa created 75 construction jobs and hundreds of supply chain jobs across several states, including California, Massachusetts, and Ohio. It is expected to support 10 permanent operations jobs.

CLIMATE BENEFIT

Alamosa is expected to generate approximately 58,000 MWh of clean energy per year. It is expected to prevent more than 34,000 metric tons of carbon dioxide emissions annually.
