Customer Choice

Smart Grid Projects Driven by Federal, State & Local Initiatives

ExamplesCentral Vermont PowerTVAState of Pennsylvania

Central Vermont Public Svc,158,000 Customers

Smart Power Program ….designed to reduce customer energy use, costs and

environmental impacts while improving storm

management …

Tennessee Valley Authority,3.5M Customers

…. the TVA Board formed Customer Resources' (CR)

Energy Efficiency/Demand Reduction (EE/DR)

organization with the responsibility of achieving a 1400

MW reduction in peak power demand by 2012. …

State of Pennsylvania, PSC, Oct 2008

…. targets of a minimum reduction in consumption of 1

percent by May 31, 2011 and of 3 percent by May 31,

2013….There also must be a minimum peak demand

reduction of 4.5 percent over the 100 highest use hours

by May 31, 2013.. …

Smart Meters

&

Advanced Metering Infrastructure (AMI)

Smart MetersDigital, not a rotary dial

Hourly & sub-hourly, not monthly

Provides status points & voltage readings

Pilot Programs

Jacksonville Electric Authority

Implemented in 2003

360K electric & 300K water meters

Three AMI systems – Primarily CellNet

Used for:

CIS billing

Enhanced outage detection/management

Enhanced connect/disconnect

Load data for planning & engineer

FPL Pilots and Implementation

3 pilot programs: 5K, then 50K, then 100K meters

SilverSpring AMI networks

275K smart meters to be installed by end of 2009

4.3M smart meters by end of 2013

California Implementations

City of Anaheim

160K water & electric meters, 5 AMI systems

Project started in 2007, complete 2008

Southern Cal

5.3 million meters

Project started in 2008

Home Area Network (HAN)

ZigBee Alliance Defining protocols for the Home Area Network

Low-cost, low-power, wireless mesh networks

Price signals are broadcast from utility via smart meters

Appliances in the home will react to pricing signals

Function to reduce peak demand or shift demand to off

peak schedules
