Business Case
Consumer Benefit
Able to better manage costs
Retailer Benefit
Wholesale cost management via demand response
Society Benefit
Reduced environmental
impact
Distributor benefit
Peak demand management via direct load
control
Smart Grid SecurityAdditional risks are not introduced that negate the benefits

UR Typical response, behavior
drops off over time
Intervention with customer creates short term stimulus
Desired effect, long term change in behavior
Key Objectives
Feedback Technologies• Test a suite of feedback technologies• Compare the impact for different levels of functionality and
engagement• Conventional methods have limited opportunities for customer
engagement
Utility solutions• Load control options for air conditioning, hot water and pool filters
(DRED)• Water Meter integration (1,500 homes)• Gas meter integration (lab only)
Simple In Home Display
• Target for unit cost to be below $50, resulting in limited functionality
• One way integration with meter
• Displays data in five minute intervals
• “Always on”. Utility has no visibility of level of engagement
Advanced In Home Display
• Assumes customer acquires device, not the utility (due to cost)
• Gets data both locally (meter) and from web (utility)
• Reduces load on utility communications network
• Displays data in five minute intervals
• “Always on”. Utility has some visibility of engagement
Achievements to date - Newington
Newington Smart Village• 700 homes with WiMAX smart meters• Selection of those with full Home Area Network (HAN)• HAN was via the customer boadband service rather than meter
Smart Home• 2 kWh natural gas powered fuel cell• 2 x solar totalling 2kWh• 16 kWh battery• Electric vehicle• Innovative appliances

Smart Meter Functionality
• Deploy 50+ standard charge points and eight fast charge points• Demonstrate demand management capability via remote controlling of
charging times • Integrate the Network Control Centre systems between Ausgrid and
Better Place
Integrated model
• Develop and test the capability for an Electric Vehicle owner to be billed for all recharging, regardless of the location of the recharge
• Demonstrate demand management capability via remote controlling of charging times
Roaming model
• Examine customer charging behaviour and receptiveness to centrally managed charging
• Examine the adoption of Electric Vehicles• Investigate Electric Vehicle charging tariffs• Evaluate possible approaches to billing and settlement• Vehicle-to-Grid simulation using Distributed Storage Application
