GreenSmith Demo Southern Company Research installing 10 Li-Ion battery storage systems to demo on the system. Will show the benefits of distributed storage 6kW, >24kWh One unit will stay in our lab for testing, the remainder will be in field demos. Integrating into our communications infrastructure Premium Power Demo SCS Research, EPRI, and two other utilities set to demo a TransFlow 2000 500kW, 2.8MWh, 480V 3φ output ZnBr Flow Battery with an estimated 30 yr life Transportable Integration to show feasibility of transportable DER tied into operations
Renewable Energy Solar Photovoltaics Incorporating Demos at GPC and APC HQs as well as any available customer installations Performance and reliability of different PV technologies will be monitored Renewable Energy Solar Photovoltaics Install 50 single-module, utility-connected photovoltaic (PV) sites in Georgia Monitor each ac module s output and sunlight input at 1- to 5-sec intervals for 18 months Generate datasets to feed into detailed distribution system circuit models Study the impacts of bringing high penetration of PV onto the distribution system
