4-year update on smart grid demonstration project

Electric Power Research Institute (EPRI)
 
The “EPRI Smart Grid Demonstration Initiative: Four Year Update” provides short case studies for each of the projects. Examples include:
·         ESB Networks: The deployment of time-of-use rates and energy information services were found to reduce overall electricity usage by 2.5 percent and peak usage by 8.8 percent.
·         Consolidated Edison: Using distributed energy resources to achieve greater reliability at the Jamaica substation might be possible for about two-thirds the cost of adding capacity.
·         Kansas City Power & Light: Opting in to receive a free device or information service does not translate into customer engagement.
·         PNM Resources: A 1-second data capture rate of photovoltaic output proved essential to use storage for smoothing functions.
·         Southern Co.: Advanced metering infrastructure capacitor bank health monitors identified more than 650 problems in the first six months and changed the inspection schedule from once a year to once a day.
·         Commonwealth Edison: Critical-peak price and peak-time rebate customers provided the largest demand reduction — up to 20 percent — while technology treatments added no measurable improvement.
