Tour of the National Solar Thermal Test Facility (NSTTF) at Sandia National Laboratories in Albuquerque, NM

Two tours of the Sandia NSTTF are being planned with the targeted dates of September 26th and September 30th, 2022. Sandia Labs is a U.S. Federal Facility and is located on a U.S. Air Force Base. Accordingly, visitors for these tours will need to register early.


The following pre-registration is required for every visitor to one of the two NSTTF tours offered as part of the SolarPACES 2022. This pre-registration is used to conduct a background check for visitors to a U.S. Federal Facility. Only those conference attendees that complete the pre-registration and obtain approval will be able to register for one of the tours later.


Please note that we can only process tour pre-registration requests until May 31, 2022. Approvals will be handled on a first-come-first-serve basis. Because we have limited space on the NSTTF tours, we highly encourage you to submit your pre-registration information as soon as possible before the May 31 deadline.

Please note that you will first get the approval. You will be able to register and pay as soon as the general conference registration is open.
Please also note that payment is NOT yet required for pre-registration.

More about the NSTTF tours

CSP R&D has been ongoing at Sandia Labs in Albuquerque, New Mexico, and Livermore, California, since the 1970s. The U.S. Department of Energy selected Sandia’s Albuquerque site to host the National Solar Thermal Test Facility. Construction began around 1976 and the NSTTF was officially opened in 1978. For over 40 years, the NSTTF has been a pioneer and leading facility in the advancement of CSP technologies worldwide. Current CSP R&D includes testing of solar integrated supercritical CO2 cycles, high temperature falling particle and liquid receivers, thermal energy storage, heliostat optics, industrial process heat applications, and autonomous collector technologies.
