Terry Daly – Customer Applications and Electric Vehicles Stream Lead

Can Smart Grids help solve the energy conundrum?

Challenge 1: Consumers reacting to price rises…

Long-term Growth Index of Rolling 12 Month Values

Challenge 2:The divergence between peak and energy growth is expected to continue….

Switch to Gas & Solar Hot Water

Price Increase

Solar PV Programs

Home Insulation

Customer Applications - Scope

20,000 Ausgrid Customers

Up to 10,000 Retailer Opt-In customers

Customer Applications – Key Objectives

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

Feedback Technologies

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

Basic Customer Portal

Advanced Customer Portal

Home Area Network (HAN)

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

Electric Vehicles

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
