Further details on winning projects will be featured in the April issue of POWERGRID International magazine. Best Energy Efficiency/Demand Response ProjectGulf Power Co. won the Energy Efficiency/Demand Response Project of the Year for its Energy Select Program. Based in Pensacola, Fla., the Southern Co. subsidiary initiated the automated dynamic pricing program for residential electricity users to increase efficiency and sustainability while meeting growing demand. The program's 10,000 participants can automate their home energy usage by programming intelligent devices through a Web portal. The devices automatically respond to the utility's dynamic pricing signals based on settings chosen by the participants. Gulf Power expects the program will expand to 16,000 participants by 2016. Runner-up for the 2013 Energy Efficiency/Demand Response Project of the Year is Western Power in Perth, Australia, for its demand response air conditioning trial. Best Grid Integration of Renewables ProjectDuke Energy Corp. won the Grid Integration of Renewables Project of the Year for the Rankin Energy Storage System. In 2010, Duke, S&C Electric Company and FIAMM, a producer of sodium-nickel-chloride batteries, solved a problem Duke was experiencing on distribution circuits with distributed solar generation: Passing clouds were causing solar energy output to fluctuate. In some cases, more than 80 percent of a solar unit's output would drop in less than five seconds. FIAMM delivered 12 sodium-nickel-chloride Zebra batteries to S&C Electric Company for assembly and testing, and the system was delivered to Duke in December 2011. Duke installed the system in the Rankin Avenue Retail Substation in Mount Holly, N.C. Since then, the battery control system has been adjusted continuously to develop the most effective way to use storage for solar integration. Runner-up for the 2013 Grid Integration of Renewables Project of the Year is Acciona Energy for implementing power management capability with advanced control and energy storage systems.
