From testing space shuttle tiles to making electricity from sunlight, the world’s first multimegawatt solar tower has contributed to energy research, space exploration, defense testing and solar energy commercialization since it was commissioned at Sandia National Laboratories in July 1978.
The solar tower is a key component of a specific type of utility-scale solar energy technology that uses hundreds of large mirrors to reflect and concentrate sunlight onto a receiver on a tower. The heat from the concentrated sunlight is absorbed by either a liquid, gas or solid and stored or used immediately in a heat exchanger to generate electricity. This type of energy, called concentrating solar power, is appealing because it can supply renewable energy — even when the sun is not shining — without using batteries for storage.

In a year-long project, researchers at Sandia and Los Alamos national laboratories teamed up with the City of New Orleans to analyze ways to increase community resilience and improve the availability of critical lifeline services during and after severe weather.

Sandia researchers then developed a tool to analyze and identify existing clusters of businesses and community resources in areas less prone to inundation — such as gas stations, grocery stores and pharmacies that could be outfitted with microgrids to boost resilience.
