view of load, improves project justifications-previously only used a snapshot of peak values

– Identifies equipment issues prior to customer complaints• Voltage, Other issues

related to unbalanced loading

– Improves effectiveness of existing capacitors-both station and line

Breaker Status knowledge– Visual Presentation to

Distribution Dispatchers– Improves outage trouble

shooting, outage history easier to analyze

– Outage prevention-Identify breakers inadvertently left in blocked position

AMI… “The Last Mile”AMI… “The Last Mile”AMI main components:

– A smart meter able to collect and store electricity interval data for its own service type plus interface with and collect and store data from other devices such as other meters and home gateways. It can also initiate and respond to two-way communications with the utility.

– A home gateway device able to collect data from, communicate with and control various energy-using appliances throughout the home such as air conditioners and hot water heaters. A home gateway also has two-way communications with the utility.

– A data collection network that provides bi-directional communication of data and commands between the home and the utility. The collection network can be publicly or privately owned and can operate using open and proprietary standards.

– An enterprise meter data management (MDM) system that provides a single, scalable repository for metering-based data along with standard interfaces to other utility systems such as CIS, OMS, GIS, and workforce management.

AMI systems also support advanced capabilities such as load control, Time-of-Use and Critical Peak Pricing, and outage and restoration reporting.
