Vision of the Future:AMR to AMI to Smart Grid


Vision of the Future: Benefits

More accurate, timely bills Complaint reduction More information available for resolving high bill issues No meter reader on site Improved public relations Faster outage detection and restoration – including nested outages Inform customers of outages to:

• Reduce energy costs through demand response programs• Reduce demand charges• Access detailed consumption and quality data• See immediate results for turn-on/turn-off

Customer pays for actual energy used – move-in/move-out Customer driven due dates and summary billing – enables SAP

functionality


Vision of the Future: More Benefits

Reduces safety incidents due to fewer field trips Enables environmental improvement

• Decreased greenhouse gas emissions

• Improved energy efficiency

• Reduced field trips and vehicle emissions

Enables net metering, Plug-in hybrid cars and distributed generation Aids in outage detection Identifies metered accounts not being billed and meter malfunctions Simplifies rate changes Provides potential new revenue from value-added products, services Reduces congestion in power lines – balanced distribution load

Suggestions Compare network size to Internet in mid-1990s Provide more than 20 years of expandable architecture

• Similar to Internet Protocol (IP) and Ethernet in 1980sProvide a subset of featuresOffer new infrastructure to accommodate higher speeds, lower latencies, greater

capacities, enhanced features and more economies of scale Ensure a secure environment

• Greater security than business Wireless LAN• More than Supervisory Control and Data Acquisition (SCADA)

Emphasize changing technology • 23 years of exponential technology growth

Needs Collaboration• Economies of scale• Interactive energy services for customers and company


Suggestions Computer controlled 300 MW load shed?

• Turn-on/turn-off through AMI network

• Home area network devices for demand response, load shed• Programmable, communicating thermostats, plug-in-hybrid cars and

generators

Support smart grid direction to minimize throwaway

• Response time and speed

• AMI is not the only connectivity

Use thoughtful approach for request for proposal and installation• Design end to end complete process

• Don’t build quick and dirt

• Think about future • upgrades of your core business objects
