This report documents the findings related to a review of power sources for six off-grid Road Weather Information Systems (RWIS) in
;
Alaska. Various power sources were reviewed as a means of reliably operating the off-grid RWIS sites throughout the year. Based on
;
information collected on current power sources and equipment used at the off-grid RWIS sites, and visits to off-grid installations in
;
Alaska, some viable methods of reliable operation were discovered. Power sources included in the study were solar photovoltaics (PV),
;
small wind turbines, fuel cells, and thermoelectric generators, all charging a battery bank which powers the weather sensors, cameras,
;
and communication equipment. The results showed that while solar PV provides enough standalone power to keep the sites operational
;
from early spring to late fall with wind supplementing this somewhat during the transition seasons, a fossil fuel based source is
;
necessary to maintain operation through the winter. These findings suggest that a combination of power sources is required for reliable
;
RWIS operation throughout the year and is dependent on the location of the site.
