Tva´s Photovoltaic Activities

This paper describes the Tennessee Valley Authority\´s (TVA) current photovoltaic (PV) activities. These include four roof-mounted 4 kWp residential arrays (which are also Southeast Residential Experiment Station field sites) and two 5-6 kWp commercial sites, all grid connected with no battery storage. Also included are approximately 30 kWp of non-grid-connected remote sites with storage (remote lighting, weather stations, etc.). Monitoring results from the two "online" residential systems are presented. Finally, TVA\´s future PV plans are discussed, both with respect to interfacing with a multitude of residential and commercial cogenerators and with regard to possible TVA PV central station plans.
